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
Dispersal is central in ecology and evolution because it influences population regulation,
adaptation, and speciation. In many species, dispersal is different between genders, leading …

Simple life-history traits explain key effective population size ratios across diverse taxa
Effective population size (N e) controls both the rate of random genetic drift and the
effectiveness of selection and migration, but it is difficult to estimate in nature. In particular …

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 …

A suite of essential biodiversity variables for detecting critical biodiversity change
Key global indicators of biodiversity decline, such as the IUCN Red List Index and the Living
Planet Index, have relatively long assessment intervals. This means they, due to their …

[HTML][HTML] Harlequin frog rediscoveries provide insights into species persistence in the face of drastic amphibian declines
Amphibians face global declines, and it remains unclear the extent to which species have
responded, and through what mechanisms, to persist in the face of emerging diseases and …
