Phylogenetic Assessment of Gazella bennettii: A Genetic Framework for the Conservation of the Endangered Jebeer in Iran

open access: yesEcology and Evolution
The chinkara (Gazella bennettii, Sykes 1831) exhibits a broad distribution from Iran to India and has been categorized into five species: G. bennettii, G. christyi, and G. salinarum representing the Indian chinkara, and G. fuscifrons and G.

Vicariance divergence and gene flow among islet populations of an endemic lizard.

open access: yes, 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 ...

Phylogenomics of Manticorini tiger beetles supports ancient Gondwanan vicariance and recent American amphitropical disjunction

open access: yes
Disjunct distributions have long fascinated biologists, particularly those found in the Southern Hemisphere. Gondwanan vicariance has been invoked to explain these patterns, with relatively limited studies having phylogenetically tested this hypothesis ...

Geographic Distributions of Homosporous Fern Taxa: Does Dispersal Obscure Evidence of Vicariance?

open access: yes, 2001
The central problem in biogeography is that interactions between different processes result in the formation of historical patterns, such that it is difficult to discriminate the relative roles of vicariance and dispersal.

The role of dispersal and vicariance in the Pleistocene history of an East African mountain rodent, **Praomys delectorum**

open access: yes, 2014
: Aim Species living in East African montane forests have highly fragmented distributions. Plio-Pleistocene climatic cycles, however, may have allowed temporary contact between forest blocks, thereby allowing gene flow.
