Population-specific gene expression responses to hybridization between farm and wild Atlantic salmon
Because of intrinsic differences in their genetic architectures, wild populations invaded by domesticated individuals could experience population-specific consequences following introgression by genetic material of ... -
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 ... -
The relationship between offspring size and fitness: integrating theory and empiricism
How parents divide the energy available for reproduction between size and number of offspring has a profound effect on parental reproductive success. Theory indicates that the relationship between offspring size and ... -
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 ... -

Why do fish stocks collapse? The example of cod in Atlantic Canada
In 1993, six Canadian populations of Atlantic cod (Gadus morhua) had collapsed to the point where a moratorium was declared on fishing. It has been argued that the collapses were caused by poor recruitment of cod to the ...
