Glossary for Chelonoidis nigra
- agricultural feature
- animal habitation
- The dwelling of an animal or group of similar animals.
- anthropogenic habitat
- A habitat that is in or on an environmental feature or material derived from human activity.
- A group of geographically or geologically associated islands.
- An arid condition is an environmental condition in which annual precipitation is less than half of annual potential evapotranspiration.
- A piece of rock with a grain size above 300 millimetres in diameter. Smaller boulders are, at times, referred to as rocks or stones.
- A feature formed by the collapse of land following a volcanic eruption.
- A high, steep, or overhanging face of rock.
- The general region of indefinite width that extends from the sea inland to the first major change in terrain features.
- conservation status
- critically endangered
- A taxon is Critically Endangered when the best available evidence indicates that it meets any of the criteria A to E for Critically Endangered, and it is therefore considered to be facing an extremely high risk of extinction in the wild
- A region rendered barren or partially barren by environmental extremes, especially by low rainfall.
- A landform elevated above the surrounding area.
- A taxon is Endangered when the best available evidence indicates that it meets any of the criteria A to E for Endangered, and it is therefore considered to be facing a very high risk of extinction in the wild.
- This taxon is still in existence, as opposed to extinct.
- A taxon is Extinct when there is no reasonable doubt that the last individual has died. A taxon is presumed Extinct when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
- extinct in the wild
- A taxon is Extinct in the Wild when it is known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range. A taxon is presumed Extinct in the Wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual. Surveys should be over a time frame appropriate to the taxon’s life cycle and life form.
- extinction status
- Indicates whether a taxon is extant (living today) or extinct.
- An area with a high density of trees. A small forest may be called a wood.
- fresh water
- An area in which grasses (Graminae) are a significant component of the vegetation.
- A category or description of the habitat in which the Event occurred.
- The one specimen or other element used or designated by the original author at the time of publication of the original description as the nomenclatural type of a species or infraspecific taxon. A holotype may be 'explicit' if it is clearly stated in the originating publication or 'implicit' if it is the single specimen proved to have been in the hands of the originating author when the description was published. [Zoo./Bot./Bio.]
- Area of dry or relatively dry land surrounded by water or low wetland.
- land bridge
- An isthmus or other land connection between what at other times are separate land masses which allows animals and plants to cross and colonise new lands. Land bridges are commonly created by regression, in which sea levels fall exposing previously submerged sections of continental shelf. Land bridges are also formed by: (a) upthrust at the edge of continental plates; and (b) glacial retreat alleviating pressure on shallow marine formations.
- Lava is an environmental material which is primarily composed of molten rock.
- The exit or point of discharge of a stream into another stream, lake or sea.
- A liquid or semi-liquid mixture of water and some combination of soil, silt, and clay.
- national park
- A reserve of land, usually, but not always declared and owned by a national government, protected from most human development and pollution. National parks are a protected area of IUCN category II.
- Continuous saline-water bodies that surround the continents and fill the Earth's great depressions.
- oceanic island
- An island that does not sit on a continental shelf, and is of volcanic origin.
- oceanic zone
- The water mass of an ocean that is not above a continental shelf.
- Grassland used for grazing of ungulate livestock as part of a farm or ranch.
- The summit of a mount.
- a naturally occurring flammable liquid consisting of a complex mixture of hydrocarbons of various molecular weights and other liquid organic compounds, that are found in geologic formations beneath the Earth's surface.
- A region of general uniform slope, comparatively level, and of considerable extent.
- An intentional planting of a crop, on a large scale, usually for uses other than cereal production or pasture. The term is currently most often used for plantings of trees and shrubs. The term tends also to be used for plantings maintained on economic bases other than that of subsistence farming.
- An elevated and comparatively level expanse of land.
- research station
- A building or collection of co-located buildings constructed for the purpose of undertaking scientific research.
- An open way for the passage of vehicles, persons, or animals on land.
- A mass of the mineral material of the crust of the Earth.
- A naturally occurring granular material composed of finely divided rock and mineral particles.
- A grassland of the tropics or subtropics with scattered trees.
- Area covered with low-growing or stunted perennial vegetation and usually not mixed with trees.
- That part of the land in immediate contact with a body of water including the area between high and low water lines.
- The part of an elevation or depression between the relatively flat surrounding area and the peak of a mount or the bottom of a depression.
- Any material within 2 m from the Earth's surface that is in contact with the atmosphere, with the exclusion of living organisms, areas with continuous ice not covered by other material, and water bodies deeper than 2 m.
- subterrestrial habitat
- A habitat that is below the surface of the earth.
- terrestrial biome
- A biome that applies to the terrestrial realm.
- terrestrial habitat
- A habitat that is on or at the boundary of the surface of the Earth.
- total life span
- The full period of time from birth to death of an organism.
- A small road, generally not paved.
- type information
- Information about type specimens or names
- volcanic field
- A region of the earth's crust that is prone to localized volcanic activity.
- An opening, or rupture, in the Earth's surface or crust, which allows hot, molten rock, ash and gases to escape from deep below the surface.
- A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.
- Land having a cover of trees, shrubs, or both.
- zoological garden
- A facility in which animals are confined within enclosures and displayed to the public, and in which they may also be bred.
