<P> The word endemic is from New Latin endēmicus, from Greek ενδήμος, endēmos, "native". Endēmos is formed of en meaning "in", and dēmos meaning "the people". The term "precinctive" has been suggested by some scientists, and was first used in botany by MacCaughey in 1917 . It is the equivalent of "endemism". Precinction was perhaps first used by Frank and McCoy . Precinctive seems to have been coined by David Sharp when describing the Hawaiian fauna in 1900: "I use the word precinctive in the sense of' confined to the area under discussion' ...' precinctive forms' means those forms that are confined to the area specified ." That definition excludes artificial confinement of examples by humans in far - off botanical gardens or zoological parks . </P> <P> Physical, climatic, and biological factors can contribute to endemism . The orange - breasted sunbird is exclusively found in the fynbos vegetation zone of southwestern South Africa . The glacier bear is found only in limited places in Southeast Alaska . Political factors can play a part if a species is protected, or actively hunted, in one jurisdiction but not another . </P> <P> There are two subcategories of endemism: paleoendemism and neoendemism . Paleoendemism refers to species that were formerly widespread but are now restricted to a smaller area . Neoendemism refers to species that have recently arisen, such as through divergence and reproductive isolation or through hybridization and polyploidy in plants . </P> <P> Endemic types or species are especially likely to develop on geographically and biologically isolated areas such as islands and remote island groups, such as Hawaii, the Galápagos Islands, and Socotra; they can equally develop in biologically isolated areas such as the highlands of Ethiopia, or large bodies of water far from other lakes, like Lake Baikal . Hydrangea hirta is an example of an endemic species found in Japan . </P>

A species with a narrow niche which can only live in a certain habitat
