Global assessment of effective population sizes: Consistent taxonomic differences in meeting the 50/500 rule

Author(s): Clarke SH; Lawrence ER; Matte JM; Gallagher BK; Salisbury SJ; Michaelides SN; Koumrouyan R; Ruzzante DE; Grant JWA; Fraser DJ;

Effective population size (Ne) is a particularly useful metric for conservation as it affects genetic drift, inbreeding and adaptive potential within populations. Current guidelines recommend a minimum Ne of 50 and 500 to avoid short-term inbreeding and to preserve long-term adaptive potential re ...

Microgeographic variation in demography and thermal regimes stabilize regional abundance of a widespread freshwater fish

Author(s): Gallagher BK; Fraser DJ;

Predicting the persistence of species under climate change is an increasingly important objective in ecological research and management. However, biotic and abiotic heterogeneity can drive asynchrony in population responses at small spatial scales, complicating species-level assessments. For widely distributed species consisting of many fragmented populat ...
