  Endemic (ecology) - Wikipedia, the free encyclopedia
In biology and ecology endemic means exclusively native to a place or biota, in contrast to cosmopolitan or introduced.
However, it is also differentiated from indigenous: a species that is endemic is unique to that place or region, found naturally nowhere else, whereas a species that is indigenous may be native to other locations as well.
Islands are especially likely to develop endemic forms because of their geographical isolation; remote island groups, such as Hawaii and the Galápagos Islands, have large numbers of endemic species.

 Endemic - Wikipedia, the free encyclopedia
Endemic, in a broad sense, can mean "belonging" or "native to", "characteristic of", or "prevalent in" a particular geography, race, field, area, or environment; native to an area or scope.
endemic (ecology): an organism being "endemic" means exclusively native to a place or biota
endemic (epidemiology), an infection is said to be "endemic" in a population when that infection is maintained in the population without the need for external inputs.

 Nat' Academies Press, Infectious Diseases in an Age of Change: The Impact of Human Ecology and Behavior on Disease ...
Climate, crowding, and hygiene profoundly influence the epidemiology of the nonvenereal treponematoses of childhood (yaws, pinta, and endemic syphilis).
Endemic syphilis was eradicated in Bosnia, and pinta disappeared in Latin America.
The influence of geography, crowding, and hygiene on transmission of the endemic treponematoses, chlamydia, and chancroid somewhat presages current concepts of the social and spatial concentrations of STD, and the spread of these infections along social networks and spatial contiguity or transportation links (41-44).

 Conservation Ecology: The Relations Among Threatened Species, Their Protection, and Taboos
Both endemic and keystone species that are important for ecosystem functions are avoided by specific-species taboos.
Among the 21 threatened species, four are endemic, i.e., confined to a very small range or to one particular region, not occurring naturally elsewhere (Primack 1993).
Other endemic populations of threatened species avoided include the southern pocket gopher Thomomys umbrinus emotus (no. 45), endemic to New Mexico, United States; the San Quintin kangaroo rat Dipodomys gravipes(no. 48), only found in Mexico; and the houserock chiseltoothed kangaroo rat Dipodomys microps leucotis (no. 49), which is restricted to Arizona, United States (Groombridge 1993).

Not only are the numbers of endemics high, but they are also are spread across virtually the whole taxonomic spectrum (an endemic is a plant or animal more or less confined to a particular area or substrate).
As in the case with plants, the centre is of exceptional zoogeographical interest because of the sharp biogeographical transformation in the region (Poynton 1961).
Of the 225 Maputaland Centre plant endemic species, 30 are associated with it and 20 restricted to it.

 The Maltese Ecology   (Site not responding. Last check: 2007-11-06)
Endemic species are of great cultural and scientific importance.
Some of the endemic plants of the islands are relics from the pre-glacial Mediterranean flora (these are called palaeoendemics) and have no close relatives anywhere else in the world.
The fauna of coastal cliffs includes some of the rarest of Maltese animals; for example, the endemic Maltese Door-snail (Lampedusa melitensis) occupies a very precarious habitat of a few tens of square metres only on the southwest cliffs of mainland Malta, while two other rare endemic snails are found in a few cliffside localities only.

 Evolution, Ecology, Conservation, and Management of Hawaiian Birds: A Vanishing Avifauna
The smallest island to hold an endemic pigeon is 28 km 2 Maketea (Tuamotu Archipelago), home to Ptilinopus chalcurus; and the smallest island to hold an endemic parrot is Norfolk Island (33.7 km 2) where remains of Nestor produetus have been recovered.
Island-group endemics Just as we saw that a greater proportion of parrots showed endemism to groups of islands than the less mobile rails, a full 51% of the pi- geons and doves are restricted to single-island groups compared to 30% for parrots.
First, the maximum number of endemics recorded represents the actual max- imum of each taxon that could occur on each type of island and, second, the recorded maxima on each island size/topography are applicable to all islands in each class.

The Terrestrial Ecology Staff's ecological assessment of the interior Columbia Basin project area included an effort to identify centers of concentration, and local hot spots, of (a) species rarity and endemism, and (b) high species richness (denoted on the maps as "biodiversity").
For refining maps of endemic plant areas, one might want to request occurrence density maps, that is, the number of plant element occurrences per county, township and range, etc., for those elements with a global ranking of G1, G2, or G3.
