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 min ...

Recruitment dynamics of juvenile salmonids: Comparisons among populations and with classic case studies

Author(s): Matte JO; Fraser DJ; Grant JWA;

Understanding recruitment, the process by which individuals are added to a population or to a fishery, is critical for understanding population dynamics and facilitating sustainable fisheries management. Important variation in recruitment dynamics is observ ...

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, complica ...

Macrogenetics reveals multifaceted influences of environmental variation on vertebrate population genetic diversity across the Americas

Author(s): Lawrence ER; Pedersen EJ; Fraser DJ;

The broad scale distribution of population-specific genetic diversity (GDP ) across taxa remains understudied relative to species diversity gradients, despite its relevance for systematic conservation planning. We used nuclear DNA data collected from 3678 v ...

Demographic resilience of brook trout populations subjected to experimental size-selective harvesting

Author(s): Clarke SH; McCracken GR; Humphries S; Ruzzante DE; Grant JWA; Fraser DJ;

Sustainable management of exploited populations benefits from integrating demographic and genetic considerations into assessments, as both play a role in determining harvest yields and population persistence. This is especially important in populations subj ...

Neutral and adaptive drivers of genomic change in introduced brook trout (Salvelinus fontinalis) populations revealed by pooled sequencing

Author(s): Brookes B; Jeon HB; Derry AM; Post JR; Rogers SM; Humphries S; Fraser DJ;

Understanding the drivers of successful species invasions is important for conserving native biodiversity and for mitigating the economic impacts of introduced species. However, whole-genome resolution investigations of the underlying contributions of neutr ...

What can be learned from fishers' perceptions for fishery management planning? Case study insights from Sainte-Marie, Madagascar

Author(s): Bernos TA; Travouck C; Ramasinoro N; Fraser DJ; Mathevon B;

Local support is critical to the success and longevity of fishery management initiatives. Previous research suggests that how resource users perceive ecological changes, explain them, and cope with them, influences local support. The objectives of this stud ...

Varying genetic imprints of road networks and human density in North American mammal populations

Author(s): Habrich AK; Lawrence ER; Fraser DJ;

Road networks and human density are major factors contributing to habitat fragmentation and loss, isolation of wildlife populations, and reduced genetic diversity. Terrestrial mammals are particularly sensitive to road networks and encroachment by human pop ...

Evaluating the correlation between genome-wide diversity and the release of plastic phenotypic variation in experimental translocations to novel natural environments.

Author(s): Yates MC, Fraser DJ

Phenotypic reaction norms are often shaped and constrained by selection and are important for allowing organisms to respond to environmental change. However, selection cannot constrain reaction norms for environmental conditions that populations have not ex ...
