The word endemic is from Neo-Latin endēmicus, from Greek ἔνδημος, éndēmos, "native". Endēmos is formed of en meaning "in", and dēmos meaning "the people". [5] The word entered the English language as a loan word from French endémique, and originally seems to have been used in the sense of diseases that occur at a constant amount in a country, as opposed to epidemic diseases ...
The forests play a vital role in harboring more than 45,000 floral and 81,000 faunal species of which 5150 floral and 1837 faunal species are endemic. [228] In addition, there are 60,065 different tree species in the world. [229] Plant and animal species confined to a specific geographical area are called endemic species.
A megadiverse country is one of a group of nations that harbours the majority of Earth's species and high numbers of endemic species. Conservation International identified 17 megadiverse countries in 1998, [1] [2] all of which are located at least partially in tropical or subtropical regions. Megadiversity means exhibiting great biodiversity.
Also Gause's law. A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
A native species in a location is not necessarily also endemic to that location. Endemic species are exclusively found in a particular place. [8] A native species may occur in areas other than the one under consideration. The terms endemic and native also do not imply that an organism necessarily first originated or evolved where it is ...
Nodding, falling headlong or face down; inclined, stooping, or bowing forward. Applied to many species with a nodding, stooping habit, such as many Narcissus and Dierama species. Many plant species bear the specific epithet "cernua". cespitose An alternative spelling of caespitose, meaning tufted or turf-like, e.g. the growth form of some ...
Islands as harbors for endemic species are explained by the theory of island biogeography. [6] However, in order to be considered a paleoendemic on an island, the species must have had a widespread distribution previously, [ 1 ] thus eliminating newly formed islands as potential refuges of paleo-endemics.
A species that occurs naturally in an area; a synonym for native species (Allaby 1998). Injurious species An introduced species that causes economic or environmental harm to humans. Similar terms include aquatic nuisance species, noxious weed, and invasive species (Heutte and Bella 2003). Intentional introduction
