They are considered relict species; two separate vicariance events probably led to the evolution of these two species ( Miller & Coyle, 1996 ).
32.
They are poorly researched and there is not enough data to assess the qualitative and quantitative parameters even of the main populations of endemic and relict species.
33.
This may be a relict species, limited in distribution to the peaks of three mountains where conditions are cool and wet enough for it to survive.
34.
California's large number of relict species, which have died out elsewhere, such as the Catalina ironwood ( " Lyonothamnus floribundus " ).
35.
This makes it likely that " T . mullamullangensis " is a relict species from the time when the now arid region was much more humid.
36.
The majority of the 33 species of the genus are found in southern Africa and Socotra, with outlying and relict species in Australia's Southwest and Kangaroo Island.
37.
Found only in the eastern region of Darien, " I . pirrensis " appears to be a relict species confined to the Panamanian side of the Serrania del Darien.
38.
Many of the late Cretaceous early Tertiary Gondwanan species of flora became extinct, but some survived as relict species in the milder, moister climate of coastal areas and on islands.
39.
They are likely relict species from a time when the region was much more humid, given the fact that the other members of the family Stiphidiidae in Southern Australia live in forests.
40.
The plant was probably widespread on the North American continent long ago, but the climate changed, and it now exists as a relict species in a narrow strip of hospitable habitat.
