Sentence examples for increase population isolation from inspiring English sources
Climate change scenarios for the region predict significant warming and rainfall decrease [75], [76], which are expected to increase population isolation and local extinction (authors, unpub. data).
This distortion is magnified by natural increases in numbers of private alleles as a function of the human population's distance from Africa [ 107, 108], owing to the concomitant reduction in genetic diversity [ 20, 22, 66, 109] as well as increases in population isolation [ 110] and human-chimpanzee dissimilarity.
On the one hand, population isolation leads to increased levels of background relatedness and inbreeding, which increases levels of homozygosity; in addition, genetic drift is stronger in small populations, which can lead to a higher frequency of mildly deleterious variants, such as LOF mutations, in small or bottlenecked populations (11).
Although selection historically maintained MHC diversity, recent population isolation and fragmentation has increased the role of genetic drift in shaping patterns of MHC variation in snub-nosed monkeys.
Both road mortality and the barrier effect caused population isolation.
In both experiments, there were no effects of population isolation.
Population isolation can alter allele frequencies among populations.
Increasing population density and social isolation would slow down adaptation, whereas improvements in health care and housing conditions would have the opposite effect.
Furthermore, because of this reduced genetic diversity (due to the bottleneck) and increased genetic drift (due to isolation), population isolates often show a lack of concordance in allele frequencies with other non-isolated populations [ 37].
Such mating conflicts have been suggested to increase reproductive isolation between populations [10] either in sympatry [11] or in allopatry [12] following secondary contact [13].
