Population-specific gene expression responses to hybridization between farm and wild Atlantic salmon
(2009-11)
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 ...
Individual variation in Atlantic salmon fertilization success: Implications for effective population size
(2002-02)
Mating structure can influence the variance in individual reproductive success, which in turn
has important implications for a population's effective size. Atlantic salmon (Salmo salar)
males are characterized by alternative ...
The relationship between offspring size and fitness: integrating theory and empiricism
(2013-02)
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 ...
Consequences of farmed-wild hybridization across divergent wild populations and multiple traits in salmon
(2010-06)
Theory predicts that hybrid fitness should decrease as population divergence increases. This
suggests that the effects of human-induced hybridization might be adequately predicted from the
known divergence among parental ...
Hybridization effects on phenotypic plasticity: experimental compensatory growth in farmed-wild Atlantic salmon
(2011-05)
Compensatory growth (CG) is a means by which organisms can increase their growth rate above
their routine growth rate after a period of environmentally induced growth depression. Despite a
focus on the implications of ...
Mixed evidence for reduced local adaptation in wild salmon resulting from interbreeding with escaped farmed salmon: complexities in hybrid fitness
(2008-08)
Interbreeding between artificially-selected and wild organisms can have negative fitness
consequences for the latter. In the Northwest Atlantic, farmed Atlantic salmon recurrently escape
into the wild and enter rivers ...
Evolutionary and ecological feedbacks of the survival cost of reproduction
(2012-04)
Arguably the most fundamental of trade-offs in life-history evolution is the increase in natural
mortality resulting from sexual maturity and reproduction. Despite its central importance, this
increase in mortality, a ...
Avoidance of fisheries-induced evolution: management implications for catch selectivity and limit reference points
(2009-08)
I examined how the fitness (r) associated with early-and late-maturing genotypes varies with
fishing mortality (F) and age-/size-specific probability of capture. Life-history data on
Newfoundland's northern Atlantic cod ...
Life-history correlates of extinction risk and recovery potential
(2012-06)
Extinction risk is inversely associated with maximum per capita population growth rate (r(max)).
However, this parameter is not known for most threatened species, underscoring the value in
identifying correlates of r(max) ...
Consequences of sexual selection for fisheries-induced evolution: an exploratory analysis
(2008-02)
Reproductive behaviour and mating system complexity may influence fisheries-induced evolution.
Mate choice and intrasexual competition might favour late-, large-maturing genotypes in contrast to
the selection imposed by ...
