That is, vicariant speciation is considered the dominant mode of speciation (Coyne & Price 2000), which will place closely related species in different areas, at least initially.
Subterranean populations are characterized by high proportion of endemic species and a large number of allopatric vicariant species often clusters in numerous metapopulations, results of geografical isolation or relicts of ancient faunas that may evolve into species with time (Porter, 2007).
The isolation from other landmasses may have facilitated the survival of relict (vicariant) taxa in Europe until Campanian-Maastrichtian times.
The distribution range is vicariant, where populations in the Ozark and Ouachita Highlands are separated from those in the Eastern Highlands.
distribution is inferred to be wide (= sum of all areas, ABcDEFG) with the occurrence of subsequent vicariant events.
Passive and active forms of water borne and air borne transport, as well as potential examples of vicariant transport will be discussed.
L'apprentissage vicariant s'opere par l'observation d'un tiers percu comme etant de competence equivalente et s'actualise par le modelage d'une attitude ou d'un comportement, particulierement dans le cas de situations jugees difficiles ou complexes par l'individu.
These subregions suggest specific microhabitats for the benthic hydroid fauna of the SO that may be derived from dispersal or vicariant events.
When the resemblance is almost complete, due to recent sympatric speciation, they are termed sibling; due to ancient allopatric speciation, they are termed vicariant (= replacing each other).
