Sentence examples for more isolated populations from inspiring English sources

Geographic separation can occur either due to vicariance, where the ancestral species is passively divided into two or more isolated populations by the erection of a barrier, such as rising of a mountain range; or dispersal, where a subpopulation actively migrates away from the ancestral range, such as an interbasinal species invasion (Wiley and Mayden 1985).

Reduced surface area and greater division of topography could lead to more isolated populations and hence higher speciation rates or endemism with increasing elevation [68], [69].

Accordingly, smaller and more isolated populations are generally characterized by low genetic diversity (e.g. [ 2]).

Hereafter, the nation name is used for general populations and a village or region name for more isolated populations.

We hoped to determine to what extent saltcedar in North America behaves as a single population as opposed to two or more isolated populations.

They demonstrate that hosts from highly connected populations are in fact more resistant to the pathogen than those from more isolated populations, most likely as a result of stronger parasite-mediated selection over time (Jousimo et al. 2014).
