Genetic estimates of contemporary effective population size: what can they tell us about the importance of genetic stochasticity for wild population persistence?

FP Palstra, DE Ruzzante - Molecular ecology, 2008 - Wiley Online Library
Genetic stochasticity due to small population size contributes to population extinction,
especially when population fragmentation disrupts gene flow. Estimates of effective …

Evolution of sex-biased dispersal

Global amphibian declines, loss of genetic diversity and fitness: a review

ME Allentoft, J O'Brien - Diversity, 2010 - mdpi.com
It is well established that a decrease in genetic variation can lead to reduced fitness and lack
of adaptability to a changing environment. Amphibians are declining on a global scale, and …
