2012: Effects of
vicariant barriers, habitat stability, population isolation and environmental features on species divergence in the south-western Australian coastal reptile community.
6B) proposes an ancient
vicariant hypothesis for Heterostylum as in Scenario 1, although not completely widespread.
Le SEP tire ses origines de quatre sources distinctes: les experiences anterieures, les experiences
vicariantes, la persuasion verbale et les etats physiologiques.
Aunque el metodo ignora las relaciones taxonomicas entre las especies al solo considerar las areas de distribucion, es posible obtener un esquema jerarquico que puede ser utilizado para proponer una regionalizacion biogeografica, e incluso puede reflejar eventos
vicariantes de relacion entre areas geograficas, a traves de la distribucion compartida de los taxones (Escalante 2011), y corroborar los resultados con filogenias disponibles de las especies que se encuentran en las areas (Rosen 1988, Morrone & Crisci 1995, Morrone 2005a).
The primary aim of many historical and evolutionary studies of marine species is to ascertain oceanographic conditions, climatic factors, and
vicariant events disrupting gene flow and genetic diversity, in relation to biogeographic patterns of demographic expansion and contraction.
Molecular differentiation of two
vicariant neotropical tree species, Plathymenia foliosa and P.
callicebi Hugot & Vaucher,1985 (Nematoda: Oxyuridae), two
vicariant form parasitic in Callicebus spp.
Minimum age constraints were imposed based on two fossils, and the
vicariant split between Palearctic and Nearctic Timarchini (Chrysomelidae).
In this study, we analyzed ospC, rrs-rrlA, ospB, and ospA (p66 contains little evolutionary information [10]) from midwestern and northeastern populations in a phylogenetic framework to investigate the shared and
vicariant evolutionary and demographic histories of B.
Although these two taxa are not sister species and the boundary between the Great Fish and Kei catchments therefore not a
vicariant feature contributing to speciation, it may well now limit dispersal and maintain the allopatry of these lineages.
