Vicariance divergence and gene flow among islet populations of an endemic lizard.
, 2011 Allopatry and allopatric speciation can arise through two different mechanisms: vicariance or colonization through dispersal. Distinguishing between these different allopatric mechanisms is difficult and one of the major challenges in biogeographical ...

BMC Evolutionary Biology, 2007 Background The importance of vicariance events on the establishment of phylogeographic patterns in the marine environment is well documented, and generally accepted as an important cause of cladogenesis. Founder dispersal (i.e.

, 2019 Background: The disjunct distribution patterns of a taxon may arise when previously continuous distribution ranges are fragmented. The phenomena of vicariance and dispersal, together with hybridisation as an important source of genetic variation in ...

Unveiling vicariant methodologies in vicariance biogeography : not anything goes
, 2000 In vicariance biogeography, the present distribution of species over areas is explained with different historical processes. Vicariance is one of these processes and involves speciation by the formation of isolating barriers between areas.

A congruent molecular signature of vicariance across multiple plant linages
, 2007 Explaining disjunct distributions, or why closely related organisms are often separated by apparently severe barriers such as oceans or deserts, is a great challenge for historical biogeography. Competing explanations are long-distance dispersal across a

, 2018 The peculiar topic of this research - perspective taking and spatial navigation - has naturally led to cross over the course of the journey other spatial navigation comprehensions.

BMC Evolutionary Biology, 2018 Background Numerous studies have favored dispersal (colonization) over vicariance (past fragmentation) events to explain eastern Asian-North American distribution patterns. In plants, however the disjunction between eastern Asia and western North America

Metapopulation vicariance in the Pacific genus Coprosma (Rubiaceae) and its Gondwanan relatives
, 2017 Coprosma is perhaps the most ubiquitous plant genus in New Zealand. It belongs to the tribe Anthospermeae, which is distinctive in the family Rubiaceae through its small, simple, wind-pollinated flowers and its southern hemisphere distribution. The tribe

Revista de Biología Tropical, 2010 The phenotypic structure within and between plant populations is generally influenced by their distribution patterns in space and time; therefore, the study of their divergence is a central issue for the understanding of their microevolutive processes ...
