definition: a core relation that holds between a part and its whole
editor note: Everything is part of itself. Any part of any part of a thing is itself part of that thing. Two distinct things cannot be part of each other.
editor note: Occurrents are not subject to change and so parthood between occurrents holds for all the times that the part exists. Many continuants are subject to change, so parthood between continuants will only hold at certain times, but this is difficult to specify in OWL. See https://code.google.com/p/obo-relations/wiki/ROAndTime
editor note: Parthood requires the part and the whole to have compatible classes: only an occurrent can be part of an occurrent; only a process can be part of a process; only a continuant can be part of a continuant; only an independent continuant can be part of an independent continuant; only an immaterial entity can be part of an immaterial entity; only a specifically dependent continuant can be part of a specifically dependent continuant; only a generically dependent continuant can be part of a generically dependent continuant. (This list is not exhaustive.) A continuant cannot be part of an occurrent: use 'participates in'. An occurrent cannot be part of a continuant: use 'has participant'. A material entity cannot be part of an immaterial entity: use 'has location'. A specifically dependent continuant cannot be part of an independent continuant: use 'inheres in'. An independent continuant cannot be part of a specifically dependent continuant: use 'bearer of'.

editor preferred term~editor preferred label: preceded by
definition: x is preceded by y if and only if the time point at which y ends is before or equivalent to the time point at which x starts. Formally: x preceded by y iff ω(y) <= α(x), where α is a function that maps a process to a start point, and ω is a function that maps a process to an end point.
editor note: An example is: translation preceded_by transcription; aging preceded_by development (not however death preceded_by aging). Where derives_from links classes of continuants, preceded_by links classes of processes. Clearly, however, these two relations are not independent of each other. Thus if cells of type C1 derive_from cells of type C, then any cell division involving an instance of C1 in a given lineage is preceded_by cellular processes involving an instance of C. The assertion P preceded_by P1 tells us something about Ps in general: that is, it tells us something about what happened earlier, given what we know about what happened later. Thus it does not provide information pointing in the opposite direction, concerning instances of P1 in general; that is, that each is such as to be succeeded by some instance of P. Note that an assertion to the effect that P preceded_by P1 is rather weak; it tells us little about the relations between the underlying instances in virtue of which the preceded_by relation obtains. Typically we will be interested in stronger relations, for example in the relation immediately_preceded_by, or in relations which combine preceded_by with a condition to the effect that the corresponding instances of P and P1 share participants, or that their participants are connected by relations of derivation, or (as a first step along the road to a treatment of causality) that the one process in some way affects (for example, initiates or regulates) the other.

contained in
type: ObjectProperty
inverse of: contains
domain: material entity
range: independent continuant
property chain axiom: located in
property chain axiom: part of
editor preferred term~editor preferred label: contained in
editor note: Containment is location not involving parthood, and arises only where some immaterial continuant is involved.
editor note: Containment obtains in each case between material and immaterial continuants, for instance: lung contained_in thoracic cavity; bladder contained_in pelvic cavity. Hence containment is not a transitive relation. If c part_of c1 at t then we have also, by our definition and by the axioms of mereology applied to spatial regions, c located_in c1 at t. Thus, many examples of instance-level location relations for continuants are in fact cases of instance-level parthood. For material continuants location and parthood coincide. Containment is location not involving parthood, and arises only where some immaterial continuant is involved. To understand this relation, we first define overlap for continuants as follows: c1 overlap c2 at t =def for some c, c part_of c1 at t and c part_of c2 at t. The containment relation on the instance level can then be defined (see definition):

editor preferred term~editor preferred label: located in
example of usage: my brain is located in my head
example of usage: this rat is located in this cage
definition: a relation between two independent continuants, the target and the location, in which the target is entirely within the location
editor note: Location as a relation between instances: The primitive instance-level relation c located_in r at t reflects the fact that each continuant is at any given time associated with exactly one spatial region, namely its exact location. Following we can use this relation to define a further instance-level location relation - not between a continuant and the region which it exactly occupies, but rather between one continuant and another. c is located in c1, in this sense, whenever the spatial region occupied by c is part_of the spatial region occupied by c1. Note that this relation comprehends both the relation of exact location between one continuant and another which obtains when r and r1 are identical (for example, when a portion of fluid exactly fills a cavity), as well as those sorts of inexact location relations which obtain, for example, between brain and head or between ovum and uterus

causally related to
type: ObjectProperty
sub property of: related via dependence to
has curation status: IAO_0000428
definition: This relation groups causal relations between material entities and causal relations between processes
editor note: This branch of the ontology deals with causal relations between entities. It is divided into two branches: causal relations between occurrents/processes, and causal relations between material entities. We take an 'activity flow-centric approach', with the former as primary, and define causal relations between material entities in terms of causal relations between occurrents. To define causal relations in an activity-flow type network, we make use of 3 primitives: * Temporal: how do the intervals of the two occurrents relate? * Is the causal relation regulatory? * Is the influence positive or negative The first of these can be formalized in terms of the Allen Interval Algebra. Informally, the 3 bins we care about are 'direct', 'indirect' or overlapping. Note that all causal relations should be classified under a RO temporal relation (see the branch under 'temporally related to'). Note that all causal relations are temporal, but not all temporal relations are causal. Two occurrents can be related in time without being causally connected. We take causal influence to be primitive, elucidated as being such that has the upstream changed, some qualities of the donwstream would necessarily be modified. For the second, we consider a relationship to be regulatory if the system in which the activities occur is capable of altering the relationship to achieve some objective. This could include changing the rate of production of a molecule. For the third, we consider the effect of the upstream process on the output(s) of the downstream process. If the level of output is increased, or the rate of production of the output is increased, then the direction is increased. Direction can be positive, negative or neutral or capable of either direction. Two positives in succession yield a positive, two negatives in succession yield a positive, otherwise the default assumption is that the net effect is canceled and the influence is neutral. Each of these 3 primitives can be composed to yiel…

comment: "There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague."

comment: https://en.wikipedia.org/wiki/ The term body of water most often refers to large accumulations of water, such as oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; Rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.

comment: The definitions of forest can vary greatly, and different classes will be needed to support the major categories. Tree cover alone is not enough to distinguish between forests and plantations. The international definition proposed by the 2010 FAO Forestry Resource Assessment: "land spanning more than 0.5 ha with trees higher than 5 metres and canopy cover of more than 10 percent, or trees able to reach these thresholds in situ . It does not include land that is predominantly under agricultural or urban land use." - FAO. 2010. Global forest resources assessment 2010, Main report, FAO Forestry Paper 163. Rome.

subclass of: Restriction

subclass of: Restriction
  on property: has quality
  some values from: PATO_0001199
definition: A linear shoaling landform feature within a body of water. Bars tend to be long and narrow (linear) and develop where a current (or waves) promote deposition of granular material, resulting in localized shallowing (shoaling) of the water. Bars can appear in the sea, in a lake, or in a river. They are typically composed of sand, although could be of any granular matter that the moving water has access to and is capable of shifting around (for example, soil, silt, gravel, cobble, shingle, or even boulders). The grain size of the material comprising a bar is related: to the size of the waves or the strength of the currents moving the material, but the availability of material to be worked by waves and currents is also important.

black smoker
type: Class
subclass of: marine hydrothermal vent
definition: A hydrothermal vent found on the ocean floor. The vents are formed in fields hundreds of meters wide when superheated water from below the Earth's crust comes through the ocean floor. The superheated water is rich in dissolved minerals from the crust, most notably sulfides, which crystallize to create a chimney-like structure around each vent. When the superheated water in the vent comes in contact with the cold ocean water, many minerals are precipitated, creating the distinctive black color. The metal sulfides that are deposited can become massive sulfide ore deposits in time.

lateral moraine
type: Class
subclass of: moraine
definition: The parallel ridges of till deposited along the sides of an alglacier. The unconsolidated debris is deposited on top of the glacier by frost shattering of the valley walls and from tributary streams flowing into the valley. The till is carried along the glacial margin until the glacier melts.

drumlin
type: Class
subclass of: hill
definition: An elongated whale-shaped hill formed by glacial action. Its long axis is parallel with the movement of the ice, with the blunter end facing into the glacial movement. Drumlins are sometimes compared to kames, but their formation is distinctively different. A drumlin is not originally shaped by meltwater, but by the ice itself and has a quite regular shape. It occurs in fine grained material, such as clay or shale, not in sands and gravels. And drumlins usually have concentric layers of material, as the ice successively plasters new layers in its movement.

saline pan
type: Class
subclass of: dry lake bed
definition: A flat expanse of ground covered with salt and other minerals, usually shining white under the sun. A salt pan is formed where water pools. A saline pan would be a lake or a pond if it were located in a climate where the rate of water evaporation were not faster than the rate of water precipitation, i.e., if it were not in a desert. If the water is unable to drain into the ground, it remains on the surface until it evaporates, leaving behind whatever minerals were dissolved. Over thousands of years, the minerals (usually salts) accumulate on the surface.

definition: An isolated hill with steep sides and a small flat top, smaller than mesas and plateaus. Buttes are formed by erosion when a cap of hard rock, usually of volcanic origin, covers a layer of softer rock that is easily worn away. This hard rock avoids erosion while the rock around it wears down.

spit
type: Class
subclass of: bar
definition: A deposition landform found off coasts. A spit is a type of bar or beach that develops where a re-entrant occurs, such as at a cove, bay, ria, or river mouth. Spits are formed by the movement of sediment (typically sand) along a shore by a process known as longshore drift. Where the direction of the shore turns inland (reenters) the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This causes a bar to build out from the shore, eventually becoming a spit.

definition: A fluvioglacial landform occurring as the result of blocks of ice calving from the front of a receding glacier and becoming partially to wholly buried by glacial outwash. Glacial outwash is generated when sediment laden streams of meltwater flow away from the glacier and are deposited to form broad outwash plains called sandurs. When the ice blocks melt, holes are left in the sandur.

subclass of: plain
definition: The plain formed by the large amounts of silt and sediment, picked up as a glacier erodes the underlying rocks as it moves slowly downhill, and at the snout of the glacier, meltwater can carry this sediment away from the glacier and deposit it on a broad plain. The material in the outwash plain is often size-sorted by the water runoff of the melting glacier with the finest materials, like silt, being the most distantly re-deposited, whereas larger boulders are the closest to the original terminus of the glacier.

comment: https://en.wikipedia.org/wiki/ If the vadose zone envelops soil, the water contained therein is termed soil moisture. In fine grained soils, capillary action can cause the pores of the soil to be fully saturated above the water table at a pressure less than atmospheric. In such soils, therefore, the unsaturated zone is the upper section of the vadose zone and not identical to it.

phreatic zone

comment: ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.

These pools are concentrations of water having an extremely high salinity as compared to the surrounding ocean, caused by the motion of large salt deposits through salt tectonics. -------------------- SOURCE DEFINITION: Marine brine pools are large areas of brine on the ocean basin. These pools are bodies of water that have a salinity three to five times greater than the surrounding ocean. For deep-sea brine pools the source of the salt is the dissolution of large salt deposits through salt tectonics. The brine often contains high concentrations of methane, providing energy to chemosynthetic animals that live near the pool.

  some values from: volcanic ash
definition: A cone that is composed of particles of silt to sand size. Explosive eruptions from a vent where the magma is interacting with groundwater or the sea (as in an eruption off the coast) produce steam and are called phreatic. The interaction between the magma, expanding steam, and volcanic gases results in the ejection of mostly small particles called ash. Fallen ash has the consistency of flour. The unconsolidated ash forms an ash cone which becomes a tuff cone or tuff ring once the ash consolidates.

definition: A cone built almost entirely of loose volcanic fragments called cinders (pumice, pyroclastics, or tephra). They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone. Most cinder cones have a bowl-shaped crater at the summit.

spatter cone
type: Class
subclass of: volcanic cone
definition: A volcanic cone formed of molten lava ejected from a vent somewhat like taffy. Expanding gases in the lava fountains tear the liquid rock into irregular gobs that fall back to earth, forming a heap around the vent. The still partly liquid rock splashed down and over the sides of the developing mound is called spatter. Because spatter is not fully solid when it lands, the individual deposits are very irregular in shape and weld together as they cool, and in this way particularly differ from cinder and ash.

ribbon lake
type: Class
subclass of: lake
definition: A lake that is long, narrow, and finger-shaped, usually found in a glacial trough. Its formation begins when a glacier moves over an area containing alternate bands of hard and soft bedrock. The sharp-edged boulders carried at the bottom of the glacier erode the softer rock more quickly by abrasion, thus creating a hollow called a rock basin. On either side of the rock basin, the more resistant rock is eroded less and these outcrops of harder rock are known as rock bars, which act as dams between which rainwater may accumulate after the retreat of the ice age, filling up the rock basin and creating a ribbon lake. A ribbon lake may also form behind a terminal or recessional moraine, both of which also act as dams, enabling water to accumulate behind them. A ribbon lake may also occur if a tributary glacier joins a main glacier. The increase in power can create a trough, which is filled with water from a river/meltwater to create a ribbon lake.

pseudocrater
type: Class
subclass of: depression
definition: A volcanic landform which resembles a true volcanic crater, but differs in that it is not an actual vent from which lava has erupted. A pseudocrater is characterised by the absence of any magma conduit which connects below the surface of the earth. Pseudocraters are formed by steam explosions as flowing hot lava crosses over a wet surface, such as a swamp, a lake, or a pond. The explosive gases break through the lava surface in a manner similar to a phreatic eruption, and the tephra builds up crater-like forms which can appear very similar to real volcanic craters.

comment: Palsas typically occur in areas with discontinuous permafrost, frequently peat bogs. A palsa consists, similarly to a pingo, of an ice core and overlying soil materials, in case of a palsa usually boggy soil. Palsas are characteristically found in areas with discontinuous permafrost and in such areas bay be the only reliable surface evidence of permafrost. A palsa needs large quantities of water for the formation of its ice core (i.e. ice lens), which is why they frequently emerge from and are bound by boggy soils, which can store enormous quantities of water in their pores. Palsas develop particularly in moorlands and are therefore also named palsamoors.

comment: 'In engineering terms, soil is referred to as regolith, or loose rock material that lies above the 'solid geology'. Soil is commonly referred to as "earth" or "dirt"; technically, the term "dirt" should be restricted to displaced soil.' https://en.wikipedia.org/wiki/Soil " The upper limit of soil is the boundary between soil and air, shallow water, live plants, or plant materials that have not begun to decompose. Areas are not considered to have soil if the surface is permanently covered by water too deep (typically more than 2.5 meters) for the growth of rooted plants. The lower boundary that separates soil from the nonsoil underneath is most difficult to define. Soil consists of horizons near the Earth's surface that, in contrast to the underlying parent material, have been altered by the interactions of climate, relief, and living organisms over time. Commonly, soil grades at its lower boundary to hard rock or to earthy materials virtually devoid of animals, roots, or other marks of biological activity. For purposes of classification, the lower boundary of soil is arbitrarily set at 200 cm."

comment: ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.
comment: This is distinct from classes such as http://purl.obolibrary.org/obo/UBERON_0001988 in that it refers to the environmental material composed primarily of feces rather than 'just' feces.

comment: ENVO bodily fluid classes differ from UBERON's treatment of bodily fluids. UBERON refers to the substance itself ("S"). We assert that UBERON's classes are the primary compositional component of the terms in ENVO ("S material"). Use of the ENVO terms is typically recommended when you wish to indicate that there may be other materials intermixed with S.

type: Class
subclass of: soil
subclass of: Restriction
  on property: part of
  some values from: technosphere
definition: Technosols are soils whose properties and pedogenesis are dominated by their technical origin. They contain a significant amount of artefacts (something in the soil recognizably made or extracted from the earth by humans), or are sealed by technic hard rock (material created by humans, having properties unlike natural rock). They include soils from wastes (landfills, sludge, cinders, mine spoils and ashes), pavements with their underlying unconsolidated materials, soils with geomembranes and constructed soils in human-made materials.

back-arc basin
type: Class
subclass of: structural basin
subclass of: Restriction
  on property: part of
  some values from: Class
    union of: ocean floor
    union of: sea floor
definition: A depression in the sea floor that results from the collision of continental plates; the weight of the sinking plate causes the overlying plate to stretch and thin, causing a basin in the overlying plate. Sometimes, the Earth's crust in these basins stretches so much it cracks, allowing magma through from the mantle beneath. Hence, basins often contain active volcanoes and hydrothermal vents.

comment: A material entity determines an environmental system when its removal would cause the collapse of that system. For example, a seamount determines a seamount environment, acting as its 'hub'. This class is currently being aligned to the Basic Formal Ontology. Following this alignment, its definition and the definitions of its subclasses will be revised.

comment: This class is defined in its geological sense: https://en.wikipedia.org/wiki/ Hydrologically, an oceanic basin may be anywhere on Earth that is covered by seawater, but geologically ocean basins are large geologic basins that are below sea level. Geologically, there are other undersea geomorphological features such as the continental shelves, the deep ocean trenches, and the undersea mountain ranges (for example, the mid-Atlantic ridge) which are not considered to be part of the ocean basins; while hydrologically, oceanic basins include the flanking continental shelves and shallow, epeiric seas.

comment: 'Terminology differs between countries. For example, in the United States, the entire dairy farm is commonly called a "dairy." The building or farm area where milk is harvested from the cow is often called a "milking parlor" or "parlor." The farm area where milk is stored in bulk tanks is known as the farm's "milk house." Milk is then hauled (usually by truck) to a "dairy plant," also referred to as a "dairy", where raw milk is further processed and prepared for commercial sale of dairy products. In New Zealand, farm areas for milk harvesting are also called "milking parlours", and are historically known as "milking sheds."' https://en.wikipedia.org/wiki/Dairy

They normally deposit the dirt or vegetation at the top of the hill to prevent it from sliding back into the colony, but in some species they actively sculpt the materials into specific shapes, and may create nest chambers within the mound.

has_exact_synonym: portion of environmental material
comment: Everything under this parent must be a mass noun. All subclasses are to be understood as being composed primarily of the named entity, rather than restricted to that entity. For example, "ENVO:water" is to be understood as "environmental material composed primarly of some CHEBI:water". This class is currently being aligned to the Basic Formal Ontology. Following this alignment, its definition and the definitions of its subclasses will be revised.

imported from: envo.owl
database_cross_reference: EcoLexicon:surface
database_cross_reference: SWEETRealm:Surface
database_cross_reference: https://en.wikipedia.org/wiki/Surface
comment: This class is distinct from a geometric surface, which is two-dimensional. The idea of "uppermost" may be problematic. Further, the definition of layer (the superclass of surface in rev 133) references surface. This may be another issue. Perhaps this can be made into an inferred class using 'bounding layer of' some material entity, note that 'bounding layer' implies containment, which may not be valid here.

upwelling
type: Class
subclass of: ocean current
definition: MERGED DEFINITION: TARGET DEFINITION: An oceanographic feature that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-deplete surface water. -------------------- SOURCE DEFINITION: A marine upwelling is a net flow of marine water to the surface of the water column from deeper regions. This is often a result of surface water displacement off continental coasts by wind action. Localised upwellings may also occur along divergent fronts around eddies and along some of the major oceanographic features. Deeper waters often have higher nutrient content; consequently blooms of primary producers, such as planktonic algae, are generally observed around upwelling zones.

database_cross_reference: https://en.wikipedia.org/wiki/Silt
comment: https://en.wikipedia.org/wiki/ In the Udden-Wentworth scale (due to Krumbein), silt particles range between 0.0039 to 0.0625 mm, larger than clay but smaller than sand particles. ISO 14688 grades silts between 0.002 mm and 0.063 mm. In actuality, silt is chemically distinct from clay, and unlike clay, grains of silt are approximately the same size in all dimensions; furthermore, their size ranges overlap. Clays are formed from thin plate-shaped particles held together by electrostatic forces, so present a cohesion. According to the U.S. Department of Agriculture Soil Texture Classification system, the sand-silt distinction is made at the 0.05 mm particle size. The USDA system has been adopted by the Food and Agriculture Organization (FAO). In the Unified Soil Classification System (USCS) and the AASHTO Soil Classification system, the sand-silt distinction is made at the 0.075 mm particle size (i.e., material passing the #200 sieve). Silts and clays are distinguished mechanically by their plasticity.

subclass of: marine biome
definition: The marine salt marsh biome comprises marshes that are transitional intertidals between land and salty or brackish marine water (e.g.: sloughs, bays, estuaries). It is dominated by halophytic (salt tolerant) herbaceous plants. The daily tidal surges bring in nutrients, which tend to settle in roots of the plants within the salt marsh. The natural chemical activity of salty (or brackish) water and the tendency of algae to bloom in the shallow unshaded water also allow for great biodiversity.

Few species were originally considered to feed directly on seagrass leaves (partly because of their low nutritional content), but scientific reviews and improved working methods have shown that seagrass herbivory is a highly important link in the food chain, with hundreds of species feeding on seagrasses worldwide, including green turtles, dugongs, manatees, fish, geese, swans, sea urchins and crabs." https://en.wikipedia.org/wiki/Seagrass 2016-01-18

  on property: part of
  some values from: marine water body
definition: Marine anoxic zones are areas of marine water that are depleted of dissolved oxygen. This condition is generally found in areas that have restricted water exchange. In most cases, oxygen is prevented from reaching the deeper levels by a physical barrier (sill) as well as by a pronounced density stratification. Anoxic conditions will occur if the rate of oxidation of organic matter by bacteria is greater than the supply of dissolved oxygen.

mesoscale marine eddy
type: Class
subclass of: marine current
definition: Mesoscale marine eddies are characterized by currents which flow in a roughly circular motion around the center of the eddy. The sense of rotation of these currents may either be cyclonic or anticyclonic. Ocean eddies are also usually made of water masses that are different to those outside of the eddy. Marine mesoscale eddies are between about 10 and 500 km in diameter, and persist for periods of days to months. They may be formed when an ocean current develops an instability. This instability grows, causing the current to meander, and eventually an eddy is pinched off from the meander.

definition: A marine Taylor column is a Taylor column that is formed in a marine body of water. Currents flowing over shoaling topography such as seamounts are accelerated and destabilised, resulting in Taylor columns. Eddies and internal waves are generated downstream of the topological feature and may extend 1000 m or so above them. This may result in a localised increase in primary production where the Taylor column reaches surface waters.

marine surface current
type: Class
subclass of: marine current
definition: A marine current bordered by the surface of the water column and the permanent thermocline, where it occurs. Surface currents are mostly wind driven and mostly limited to the top 400 m of the water column. Ocean currents are driven by the circulation of wind above surface waters. Frictional stress at the interface between the ocean and the wind causes the water to move in the direction of the wind. Large ocean currents are a response of the atmosphere and ocean to the flow of energy from the tropics to polar regions. In some cases, currents are transient features and affect only a small area. Other ocean currents are essentially permanent and extend over large horizontal distances.

definition: The marine sublittoral zone is part of the marine littoral zone which is permanently covered by seawater. In physical oceanography, the sublittoral zone refers to coastal regions with significant tidal flows and energy dissipation, including non-linear flows, internal waves, river outflows and oceanic fronts. In practice, this typically extends to the edge of the continental shelf, with depths around 200 meters. In marine biology, the sublittoral refers to the areas where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone.

determinate root nodule
type: Class
subclass of: root nodule
definition: Determinate nodules are root nodules found on tropical (sub)legumes, such as those of the genera Glycine (soybean), Phaseolus (common bean), Lotus, and Vigna. Determinate nodules lose meristematic activity shortly after initiation, thus growth is due to cell expansion resulting in mature nodules which are spherical in shape.

indeterminate root nodule
type: Class
subclass of: root nodule
definition: Indeterminate nodules are found on temperate legumes like Pisum (pea), Medicago (alfalfa), Trifolium (clover), and Vicia (vetch). They earned the moniker "indeterminate" because they maintain an active apical meristem that produces new cells for growth over the life of the nodule. Because they are actively growing, indeterminate nodules manifest zones which demarcate different stages of development/symbiosis.

type: Class
subclass of: PATO_0001018
has curation status: IAO_0000121
definition: An environmental condition is a range of a determinate quality or combination of qualities that are present in an environmental system.

comment: A condition defines a restricted range of a given quality or combination of qualities. If an environment class, E, has_condition C, then all qualities listed in C are restricted to the ranges defined in C in E. This is not intended as a logical conditional.

tropical
type: Class
subclass of: environmental condition
definition: A tropical condition is an environmental condition in which an environmental system receives high yearly solar irradiance per unit area and, on Earth, the Sun reaches a subsolar point at least once during the solar year. This results in a hot and moist year-round climate at low elevations, which have a monthly average temperature above 18 degrees Celsius.

subtropical
type: Class
subclass of: environmental condition
definition: A subtropical condition is an environmental condition in which an envrionmental system receives more solar irradiance than those with temperate conditions, but less than those with tropical conditions. At low elevations, this typically results in eight months of the year having average temperatures greater than or equal to 10 degrees Celsius with the coldest monthly temperature averaging between 2 and 13 degrees Celsius.

comment: As with most other climatic zones and conditions, multiple classification schemes have somehat different definitions and criteria. To quote from https://en.wikipedia.org/wiki/ "Several methods have been used to define the subtropical climate. In the Trewartha climate classification, a subtropical region should have at least eight months with a mean temperature of 10 °C (50.0 °F) or above. German climatologists Carl Troll and Karlheinz Paffen defined Warm temperate zones as plain and hilly lands having an average temperature of the coldest month between 2 °C (35.6 °F) and 13 °C (55.4 °F) in the Northern Hemisphere and between 6 °C (42.8 °F) and 13 °C (55.4 °F) in the Southern Hemisphere, excluding oceanic and continental climates. According to the Troll-Paffen climate classification, there generally exists one large subtropical zone named the warm-temperate subtropical zone,[4] which is subdivided into seven smaller areas.[5] According to the E. Neef climate classification, the subtropical zone is divided into two parts: Rainy winters of the west sides and Eastern subtropical climate.[6] According to the Wilhelm Lauer & Peter Frankenberg climate classification, the subtropical zone is divided into three parts: high-continental, continental, and maritime.[7] According to the Siegmund/Frankenberg climate classification, subtropical is one of six climate zones in the world.[8]"

temperate

felsic lava
type: Class
subclass of: lava
definition: Felsic lava is lava which is high in silica (> 69 percent by weight), aluminium, potassium, sodium, and calcium, forming a polymerized liquid rich in feldspar and quartz. Felsic lava has a higher viscosity than other magma types. Felsic magmas can erupt at temperatures as low as 650 to 750 °C. Unusually hot (>950 °C) rhyolite lavas, however, may flow for distances of many tens of kilometres

intermediate lava
type: Class
subclass of: lava
definition: Intermediate lava is lava which, relative to felsic lava, is lower in aluminium and silica (between 52 and 63 percent by weight), and usually somewhat richer in magnesium and iron. The temperature of intermediate lava ranges from 750 to 950 degrees Celsius, destroying polymerized bonds and promoting more fluid behaviour relative to felsic lavas and also a greater tendency to form phenocrysts. Higher iron and magnesium tends to manifest as a darker groundmass, and also occasionally amphibole or pyroxene phenocrysts.

mafic lava
type: Class
subclass of: lava
definition: Mafic lava is lava which, relative to other lava types other than ultramafic lava, has a high ferromagnesian content and low aluminium and silica content, with silca making up between 45 and 52 percent of its weight. Mafic lava generally erupts at temperatures in excess of 950 degrees Celsius. The high temperature and low polymerisation in mafic lava favors low viscosity and chemical diffusion, promoting the formation of large, well-formed phenocrysts.

type: Class
subclass of: lava
definition: Ultramafic lava is lava which, relative to other lava types, has very high magnesium oxide content and less than 45 percent silica by weight is thought to have erupted at temperatures of 1600 degrees Celsius. Due to its high temperature and composition, the viscosity of ultramafic lava is very low.

comment: In ENVO's alignment with the Basic Formal Ontology, this class is being considered as a subclass of a proposed BFO class "system". The relation "environed_by" is also under development. Roughly, a system which includes a material entity (at least partially) within its site and causally influences that entity may be considered to environ it. Following the completion of this alignment, this class' definition and the definitions of its subclasses will be revised.

comment: Note that the definition of the term mineral is debatable; however, a mineral generally must be naturally occuring, stable at room temperature, representable by a chemical formula (unlike rocks, which may include a wide variety of components), are usually formed by geophysical processes (i.e. are abiogenic), and have an ordered atomic arrangement.

definition: A mineral material is an environmental material which is primarily composed of some substance that is naturally occurring, solid and stable at room temperature, representable by a chemical formula, usually abiogenic, and that has an ordered atomic structure.
editor note: Look for "mineral" in a chemical or geochemical ontology to formalise the composed primarily of link. From https://en.wikipedia.org/wiki/ [A mineral] is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition. The exact definition of a mineral is under debate, especially with respect to the requirement a valid species be abiogenic, and to a lesser extent with regards to it having an ordered atomic structure.

comment: A similar term exists in linguistics and mathematics. An ecocline, or biological cline, is a related concept; however, may be better placed as a child of a class like "ecotone". Further, some definitions of "layer" require a layer's constiuent materials to have consistent properties, thus "cline" would not qualify as a subclass. The term "gradient" has been proposed as a more suitable superclass. Discussion in Issue #286)

comment: There is debate on the usage of mudstone and mudrock, and some ambiguity is to be expected. https://en.wikipedia.org/wiki/ The terminology of "mudstone" is not to be confused with the Dunham classification scheme for limestones. In Dunham's classification, a mudstone is any limestone containing less than ten percent carbonate grains. Note, a siliciclastic mudstone does not deal with carbonate grains. Friedman, Sanders, and Kopaska-Merkel (1992) suggest the use of "lime mudstone" to avoid confusion with siliciclastic rocks.

comment: ENVO contains this top-level class, but all instances will be in GAZ. The definition is preliminary and will be aligned to BFO. https://en.wikipedia.org/wiki/ Ecozones correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. Ecozones are characterized by the evolutionary history of the organisms they contain. They are distinct from biomes, also known as major habitat types, which are divisions of the Earth's surface based on life form, or the adaptation of plants and animals to climatic, soil, and other conditions. Biomes are characterized by similar climax vegetation. Each ecozone may include a number of different biomes. A tropical moist broadleaf forest in Central America, for example, may be similar to one in New Guinea in its vegetation type and structure, climate, soils, etc., but these forests are inhabited by plants and animals with very different evolutionary histories.

dimictic lake
type: Class
subclass of: holomictic lake
definition: A dimitic lake is a holomictic lake which mixes from top to bottom during two mixing periods each year. Mixing typically occurs during the spring and autumn, when the lake is "isothermal" (i.e., at the same temperature from the top to the bottom). At this time the water throughout the lake is about 4°C, and, in the absence of any temperature or density differences, the lake readily mixes from top to bottom. These lakes are common in regions with temperate climates.

subclass of: field
subclass of: Restriction
  on property: composed primarily of
  some values from: mesoscale marine eddy
definition: A mesoscale eddy field is an expanse of marine water which includes coherent vortices, as well as a rich cascade of other structures such as filaments, squirts and spirals and is characterized by temperature and salinity anomalies with associated flow anomalies that are nearly in geostrophic balance. Although only the surface expression of mesoscale eddies is visible in satellite images of sea surface height or temperature, they are in fact three dimensional structures that reach down into the pycnocline.

cold desert
type: Class
subclass of: desert area
definition: A cold desert is a desert which has hot summers and cold, dry winters with temperatures below 0 degrees Celsius
imported from: envo.owl
in_subset: envoPolar
comment: This variant of the desert climate is somewhat rare outside of Asia. A cold desert climate is typically found in temperate zones, almost always in the rain shadow of high mountains which restrict precipitation from the westerly winds, or in the case of Central Asia, from the monsoon. The Gobi desert in Mongolia is a classic example of a region with a cold desert climate. Though hot in summer, it shares the very cold winters of the rest of Central Asia. The Kyzyl Kum and Taklamakan deserts of Central Asia and the drier portions of the Great Basin Desert of the western United States are other major examples of BWk climates. The Ladakh region, lying in the Great Himalayas in India also has a cold desert climate.

definition: Andesite is an extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic texture. In a general sense, it is the intermediate type between basalt and dacite, and ranges from 57 to 63 percent silicon dioxide as illustrated in TAS diagrams. The mineral assemblage is typically dominated by plagioclase plus pyroxene and/or hornblende. Magnetite, zircon, apatite, ilmenite, biotite, and garnet are common accessory minerals. Alkali feldspar may be present in minor amounts.
imported from: envo.owl

dacite
type: Class
subclass of: igneous rock
definition: Dacite is an igneous, volcanic rock. It has an aphanitic to porphyritic texture and is intermediate in composition between andesite and rhyolite. Dacite consists mostly of plagioclase feldspar with biotite, hornblende, and pyroxene (augite and/or enstatite). It has quartz as rounded, corroded phenocrysts, or as an element of the ground-mass. The plagioclase ranges from oligoclase to andesine and labradorite. Sanidine occurs, although in small proportions, in some dacites, and when abundant gives rise to rocks that form transitions to the rhyolites.

wet meadow ecosystem
type: Class
subclass of: meadow ecosystem
definition: A wet meadow is a type of wetland with soils that are saturated with water for part or all of the growing season.
imported from: envo.owl
comment: Debate exists whether a wet meadow is a type of marsh or a completely separate type of wetland. Wet prairies and wet savannas are hydrologically similar. Wet meadows may occur because of restricted drainage or the receipt of large amounts of water from rain or melted snow. They may also occur in riparian zones and around the shores of large lakes. Unlike a marsh or swamp, a wet meadow does not have standing water present except for brief to moderate periods during the growing season. Instead, the ground in a wet meadow fluctuates between brief periods of inundation and longer periods of saturation. Wet meadows often have large numbers of wetland plant species, which frequently survive as buried seeds during dry periods, and then regenerate after flooding. Wet meadows therefore do not usually support aquatic life such as fish. They typically have a high diversity of plant species, and may attract large numbers of birds, small mammals and insects including butterflies.

definition: The lowest of the concentric layers of the atmosphere, occurring between the Earth's surface and the tropopause. It is the zone where atmospheric turbulence is at its greatest and where the bulk of the Earth's weather is generated. It contains almost all the water vapour and aerosols and three-quarters of the total gaseous mass of the atmosphere. Throughout the troposphere temperature decreases with height at a mean rate of 6.5°C/km and the whole zone is capped by either an inversion of temperature or an isothermal layer at the tropopause.

definition: Paraffin is a thin, clear liquid composed of hydrocarbons that typically contain between 6 and 16 carbon atoms per molecule. Paraffin is obtained from the fractional distillation of petroleum between 150 and 275 degrees Celsius, resulting in a mixture with a density of 0.78–0.81 grams per cubic centimetre. It is miscible in petroleum solvents but immiscible in water. Regardless of crude oil source or processing history, kerosene's major components are branched and straight chain alkanes and naphthenes (cycloalkanes), which normally account for at least 70% by volume. Aromatic hydrocarbons in this boiling range, such as alkylbenzenes (single ring) and alkylnaphthalenes (double ring), do not normally exceed 25% by volume of kerosene streams. Olefins are usually not present at more than 5% by volume.

liquefied natural gas
type: Class
subclass of: liquefied hydrocarbon gas
definition: Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4) that has been converted to liquid form for ease of storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state. It is odorless, colorless, non-toxic and non-corrosive. LNG achieves a higher reduction in volume than compressed natural gas (CNG) so that the (volumetric) energy density of LNG is 2.4 times greater than that of CNG or 60 percent of that of diesel fuel.

piece of furniture
type: Class
subclass of: manufactured product
definition: A piece of furniture is a movable object intended to support various human activities such as seating (e.g., chairs, stools and sofas) and sleeping (e.g., beds).
imported from: envo.owl
comment: The assumption is that furniture is manufactured, which is arguable. Further, according to Black's Law Dictionary (http://thelawdictionary.org/furniture/) many classes can be subclasses of 'piece of furntiure': "This term includes that which furnishes, or with which anything is furnished or supplied; whatever must be supplied to a house, a room, or the like, to make it habitable, convenient, or agreeable; goods, vessels, utensils, and other appendages necessary or convenient for housekeeping; whatever is added to the interior of a house or apartment, for use or convenience. Bell v. Holding, 27 Ind. 173.The term “furniture” embraces everything about the house that has been usually enjoyed there, including plate, linen, china, and pictures. 1 Endicott v. Endicott, 41N. J. Eq. 96, 3 Atl. 157.The word “furniture” made use of in the disposition of the law. or in the conventions or acts of persons, comprehends only such furniture as is intended for use and ornament of apartments, but not libraries which happen to be there, nor plate. Civ.Code La. art. 477." However, this would eventually be absurd and limit other groupings. Perhaps some sort of 'furnishing' BFO:function would be a better way to handle this.

comment: "Soil Erosion is a common term that is often confused with soil degradation as a whole, but in fact refers only to absolute soil losses in terms of topsoil and nutrients. This is indeed the most visible effect of soil degradation, but does not cover all of its aspects. Soil erosion is a natural process in mountainous areas, but is often made much worse by poor management practices." http://www.fao.org/soils-portal/soil-degradation-restoration/en/

comment: A class created fro SDGIO. The definition of rural is highly varied, dealing with areas, settlements, and populations interchangeably. The 'rural' classes in ENVO aim to clarify these differing definitions. See issue #272.

village
type: Class
subclass of: populated place
definition: A village is a clustered human settlement or community, larger than a hamlet but smaller than a town, with a population ranging from a few hundred to a few thousand. Though often located in rural areas, the term urban village is also applied to certain urban neighbourhoods. Villages are normally permanent, with fixed dwellings; however, transient villages can occur. Further, the dwellings of a village are fairly close to one another, not scattered broadly over the landscape, as a dispersed settlement.
editor note: This class may be split. "urban village" doesn't sit well and prevents relations to village biomes.

definition: An object which is composed of one or more gravitationally bound structures that are associated with a position in space.
imported from: envo.owl
has_related_synonym: celestial object

comment: If there is only one astronomical body involved, this class is equivalent to ENVO:01000799. This may be problematic with reasoning, but it seems to be true to the rather fuzzy definitions found thus far.

globular star cluster
type: Class
subclass of: astronomical object
definition: A group of gravitationally bound stars.
imported from: envo.owl
in_subset: envoAstro
comment: There is a need to account for open star clusters which are not gravitationally bound. This would need a superclass other than 'astronomical object', as currently defined.

comment: Considerable debate on this definition exists.

minor planet
type: Class
subclass of: astronomical body
definition: A minor planet is an astronomical object in direct orbit around the Sun that is neither a planet nor exclusively classified as a comet. Minor planets can be dwarf planets, asteroids, trojans, centaurs, Kuiper belt objects, and other trans-Neptunian objects.
editor note: This definition is in need of revision - it relies on negation and seems to straddle class and instance level. The definitional space here is contested and quite inhomogeneous.
imported from: envo.owl
in_subset: envoAstro
comment: "Before 2006, the IAU had officially used the term minor planet. During its 2006 meeting, the IAU reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSB). Objects are called dwarf planets if their self-gravity is sufficient to achieve hydrostatic equilibrium and form an ellipsoidal shape. All other minor planets and comets are called small Solar System bodies. The IAU stated that the term minor planet may still be used, but the term small Solar System body will be preferred. However, for purposes of numbering and naming, the traditional distinction between minor planet and comet is still used."

The NLCD 2011 continues to state that more than 75% of these trees should shed foliage simultaneously in response to seasonal change. Such thresholds - which are themselves fuzzy - are not asserted in this definition.

alternative term: developed, high intensity
imported from: envo.owl
has_alternative_id: NLCD:24
in_subset: nlcd2011
comment: According to the NLCD 2011, areas of developed space under high intensity usage are dominated by constructed features where humans reside and work. Examples include apartment complexes, row houses and commercial/industrial facilities. Further, it is asserted that "impervious surfaces", most likely referring to concrete and related substances, cover between than 80 - 100% of the area. Such thresholds - which are themselves fuzzy - are not strictly asserted in this definition.

has_related_synonym: aquatic farming
comment: In 1988, the FAO introduced a definition of aquaculture which reduces its confusion with capture fisheries: Aquaculture is the farming of aquatic organisms, including fish, molluscs, crustaceans and aquatic plants. Farming implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, protection from predators, etc. Farming also implies individual or corporate ownership of the stock being cultivated. For statistical purposes, aquatic organisms which are harvested by an individual or corporate body which has owned them throughout their rearing period contribute to aquaculture, while aquatic organisms which are exploitable by the public as a common property resources, with or without appropriate licences, are the harvest of fisheries.

time crystal
type: Class
subclass of: environmental material
definition: An open system in non-equilibrium with its environment that exhibits time translation symmetry breaking.
imported from: envo.owl
has_exact_synonym: space-time crystal
comment: While the usage of the term is still debated, the general idea is that time crystals (which have been made using ytterbium ions and defect-bearing diamonds) break temporal symmetry analogously to how mineral crystal break spatial symmetry. While spatial crystals are inhomogeneous in space (vs a gas, which is distributed evenly) due to the ordering of their atoms, the properties of atoms in a time crystal are inhomogeneous in the time dimension.

has_exact_synonym: anthropization
comment: An area may be classified as anthropized even though it looks natural, such as grasslands that have been deforested by humans. It can be difficult to determine how much a site has been anthropized in the case of urbanization because one must be able to estimate the state of the landscape before significant human action.

primary atmosphere
type: Class
subclass of: planetary atmosphere
definition: A planetary atmosphere which is formed as a result of the accretion of gaseous matter from the accretion disc of the planet's star.
imported from: envo.owl
comment: Planets such as Jupiter and Saturn have primary atmospheres. Primary atmospheres are very thick compared to secondary atmospheres like the one found on Earth. The primary atmosphere was lost on the terrestrial planets due to a combination of surface temperature, mass of the atoms and escape velocity of the planet.

secondary atmosphere
type: Class
subclass of: planetary atmosphere
definition: A planetary atmosphere which has formed as a result of its planet's volcanic activity, or by accumulation of material from comet impacts.
imported from: envo.owl
comment: A secondary atmosphere is found on many terrestrial planets such as Mercury, Venus, and Mars. Secondary atmospheres are relatively thin compared to primary atmospheres like Jupiter's. Earth has a tertiary atmosphere due to biotic processes.

tertiary atmosphere
type: Class
subclass of: planetary atmosphere
definition: A planetary atmosphere which has formed as a result of biotic processes modifying a secondary atmosphere.
editor note: This definition cites biotic processes; however, the source indicated that other processes may cause a secondary atmosphere to transition into a tertiary one. More input is needed.
imported from: envo.owl
comment: Further processing of a secondary atmosphere, for example by the processes of biological life, can produce a tertiary atmosphere, such as that of Earth.

comment: This material is easily crumbled into a fine white to off-white powder. The powder has a particle size ranging from less than 3 micrometres to more than 1 millimetre, but typically 10 to 200 micrometres. The diatoms in each deposit contain different amounts of silica, depending on the age of the deposit. The species of diatom may differ among deposits. The species of diatom is dependent upon the age and paleo-environment of the deposit. In turn, the shape of a diatom is determined by its species. The typical chemical composition of oven-dried diatomaceous earth is 80 to 90% silica, with 2 to 4% alumina (attributed mostly to clay minerals) and 0.5 to 2% iron oxide.

definition: An environmental system within which an environmental material strongly influences the system's composition and properties.
imported from: envo.owl
comment: Organisational class. Not intended for annotation. Subclasses describe environments which are usually permeated by an environmental material. They may also describe environments which are sufficiently close to a material, that their dynamics are strongly influenced by it (e.g. a patch of forest ecosystem neighbouring a uranium dump).

alternative term: Non-saline
imported from: envo.owl
in_subset: envoEmpo
comment: This class (term) is defined by the lack of a quality (i.e. the lack of salinity or increased osmolarity), which is not best-practice ontologically. Use for annotation is generally discouraged and users should use classes which positively describe the material or environment sampled (i.e. stating the qualities the entity has, rather than those it does not).

subclass of: rainbow
definition: A solar rainbow is a rainbow produced by the refraction of light. which has been emitted by a star, by water droplets in the atmosphere of an astronomical body.
imported from: envo.owl

reflection rainbow
type: Class
subclass of: rainbow
definition: A rainbow which forms from sunlight which has been reflected off a body of water prior to its interaction with water droplets in an atmosphere.
imported from: envo.owl
comment: Not to be confused with a reflected rainbow, which is not a photometeor.

monochrome solar rainbow
type: Class
subclass of: solar rainbow
definition: A solar rainbow which is formed by a narrow band of wavelengths, the rest of the spectrum having been scattered away by an atmosphere.

fogbow
type: Class
subclass of: rainbow
subclass of: Restriction
  on property: overlaps
  some values from: Class
    union of: cloud
    union of: fog
definition: A rainbow which forms through the interaction of sunlight with the water droplets which constitute fog or clouds; light is diffracted by these droplets such that the photometeor appears almost white with faint reds on the sky-facing side and faint blues on the planet-facing side of the bow.
imported from: envo.owl
has_exact_synonym: fog bow
comment: Often, fogbows are treated as separate from rainbows; however, as the formation processes are much the same, we currently classify these as a subclass of rainbow pending input from domain experts.

glory
type: Class
subclass of: photometeor
definition: A photometeor which is formed by wave interference of light refracted within water droplets which constitute mist or clouds and consists of one or more concentric, successively dimmer rings, each of which has red wavelengths distant to the glory's centre and blue wavelengths towards the centre.
imported from: envo.owl
comment: This is not to be confused with a circular rainbow, which is formed through different processes.

humic lake
type: Class
subclass of: lake
definition: A lake which is composed primarily water with high concentrations of humic substances and organic acids, resulting in brown- or tea-coloured colouration.
imported from: envo.owl
has_exact_synonym: dystrophic lake
comment: In response to historical misuse of the term in literature, these lakes are better referred to as "humic lakes". Although dystrophic lakes are often considered acidic and nutrient-poor (oligotrophic), these lakes actually vary greatly in terms of both pH and productivity. Due to the low pH associated with dystrophic lakes, few bacterial species and other aquatic life are able to survive. They are common in the taiga of North America and Eurasia.
