Glossary for Chelonoidis nigra
- Animal habitation
- The dwelling of an animal or group of similar animals.
- An arid condition is an environmental condition in which annual precipitation is less than half of annual potential evapotranspiration.
- 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 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.
- The natural environment in which an organism lives, or the physical environment that surrounds (influences and is utilized by) a species population.
- Habitat. (2013, August 9). In Wikipedia, The Free Encyclopedia. Retrieved 19:01, August 14, 2013, from http://en.wikipedia.org/w/index.php?title=Habitat&oldid=567783959
- 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.]
- Lava is an environmental material which is primarily composed of molten rock.
- Oceanic island
- An island that does not sit on a continental shelf, and is of volcanic origin.
- An elevated and comparatively level expanse of land.
- 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.
- Shrubland biome
- A shrubland biome is a terrestrial biome which includes, across its entire spatial extent, dense groups of shrubs.
- 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.
- 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.
- Type Information
- Information about type specimens or names
- Volcanic field
- A region of the earth's crust that is prone to localized volcanic activity.
- 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.
