Genetic estimates of contemporary effective population size: what can they tell us about the importance of genetic stochasticity for wild population persistence?
A review of the body of empirical estimates of effective population size for wild populations obtained with the temporal genetic method and published since Frankham's (1995 ) review finds that particularly model selection and sampling require more attention in future studies. Expand
Parallel adaptive evolution of Atlantic cod on both sides of the Atlantic Ocean in response to temperature
Despite the enormous economic and ecological importance of marine organisms, the spatial scales of adaptation and biocomplexity remain largely unknown. Yet, the preservation of local stocks thatExpand
Understanding and estimating effective population size for practical application in marine species management.
The practical utility of estimating N(e) is emphasized by highlighting its relevance to the adaptive potential of a population and describing applications in management of marine populations, where the focus is not always on critically endangered populations. Expand
Microsatellite polymorphism and the population structure of Atlantic cod (Gadus morhua) in the northwest Atlantic
Allelic variation in six highly polymorphic microsatellite loci (mean heterozygosity, 86%) provided evidence that cod (Gadus morhua) in the northwest Atlantic belong to multiple geneticallyExpand
Power for detecting genetic divergence: differences between statistical methods and marker loci
Computer simulations are used to assess and evaluate power when testing for genetic differentiation at multiple loci through combining test statistics or P values obtained by four different statistical approaches, viz. Expand
Marine landscapes and population genetic structure of herring (Clupea harengus L.) in the Baltic Sea
Application of a novel method for detecting barriers to gene flow by combining geographical coordinates and genetic differentiation allowed us to identify two zones of lowered gene flow that were concordant with the separation of the Baltic Sea into major basins, with environmental gradients and with differences in migration behaviour.

Disentangling the Effects of Evolutionary, Demographic, and Environmental Factors Influencing Genetic Structure of Natural Populations: Atlantic Herring as a Case Study
The genetic signal left by the demographic history of herring seems to have been largely eroded, which is not surprising given the large reproductive potential and presumed enormous local effective population sizes of pelagic fish that constrain the effect of stochastic processes. Expand
A nuclear DNA basis for shelf‐ and bank‐scale population structure in northwest Atlantic cod (Gadus morhua): Labrador to Georges Bank
It is suggested that bathymetric and hydrodynamic structure represents a rational starting point for developing hypotheses to examine the processes that lead to the genetic structuring of marine fish species. Expand
The genetic structure of Atlantic cod (Gadus morhua) around Iceland: insight from microsatellites, the Pan I locus, and tagging experiments
Allelic variation at nine microsatellite loci and the Pan I locus provides evidence that Atlantic cod around Iceland is genetically structured and a genetic differentiation between cod from the northeastern and southwestern regions is confirmed. Expand
Biocomplexity in a highly migratory pelagic marine fish, Atlantic herring
Evidence of correlated genetic and life history differentiation in an abundant and highly migratory pelagic fish, Atlantic herring, Clupea harengus, in the North Sea and adjacent areas is described and suggests the existence of more complex patterns of intraspecific diversity than was previously recognized.
