Potential for anthropogenic disturbances to influence evolutionary change in the life history of a threatened salmonid
Although evolutionary change within most species is thought to occur slowly, recent studies have identified cases where evolutionary change has apparently occurred over a few generations. Anthropogenically altered ...
Relative risks of inbreeding and outbreeding depression in the wild in endangered salmon
Conservation biologists routinely face the dilemma of keeping small, fragmented populations isolated, wherein inbreeding depression may ensue, or mixing such populations, which may exacerbate population declines via ...
Genomic islands of divergence and their consequences for the resolution of spatial structure in an exploited marine fish
As populations diverge, genomic regions associated with adaptation display elevated differentiation. These genomic islands of adaptive divergence can inform conservation efforts in exploited species, by refining the ...
Concurrent habitat and life history influences on effective/census population size ratios in stream-dwelling trout
Lower effective sizes (Ne) than census sizes (N) are routinely documented in natural populations, but knowledge of how multiple factors interact to lower N-e/N ratios is often limited. We show how combined habitat and ...
The Ecology of Atlantic Cod (Gadus morhua) in Canadian Arctic Lakes
The range of limnological conditions that support Atlantic cod populations in meromictic Arctic lakes is known to be relatively restricted. The degree to which differences in these features, particularly in the availability ...
The Influence of Operational Sex Ratio on the Intensity of Competition for Mates
The evolution and maintenance of secondary sexual characteristics and behavior are heavily influenced by the variance in mating success among individuals in a population. The operational sex ratio (OSR) is often used as ...
