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 ...
Predicting and verifying the intended and unintended consequences of large-scale ocean iron fertilization
(2008)
Ocean iron fertilization (OIF) is being considered as a strategy for mitigating rising atmospheric CO2 concentrations. One model for implementation is the sale of carbon offsets. Modeling studies predict that OIF has the ...
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 ...
Polar Bear Diets and Arctic Marine Food Webs: Insights from Fatty Acid Analysis
(2008-11)
We used quantitative fatty acid signature analysis (QFASA) to examine the diets of 1738
individual polar bears (Ursus maritimus) sampled across the Canadian Arctic over a 30-year span.
Polar bear foraging varied over ...
Potential for anthropogenic disturbances to influence evolutionary change in the life history of a threatened salmonid
(2008-05)
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 ...
Synthesis of dipyrrins bearing chirality adjacent to the conjugated skeleton - Electron-poor pyrroles exhibit dramatically reduced nucleophilicity
(2008-10)
With the aim of furthering our investigations into the asymmetric complexation of dipyrrinato
ligands, a dipyrrin bearing a stereogenic centre directly adjacent to the conjugated skeleton was
synthesized. The electron- ...
Pacific Salmon in Hot Water: Applying Aerobic Scope Models and Biotelemetry to Predict the Success of Spawning Migrations
(University of Chicago Press, P.O. Box 37005 Chicago IL 60637 USA,
[mailto:help@press.uchicago.edu], [URL:http://www.journals.uchicago.edu/], 2008-12)
Concern over global climate change is widespread, but quantifying relationships between
temperature change and animal fitness has been a challenge for scientists. Our approach to this
challenge was to study migratory ...

(2008-08)
Interbreeding between artificially-selected and wild organisms can have negative fitness

Otolith elemental composition and adult tagging reveal spawning site fidelity and estuarine dependency in rainbow smelt
(2008)
Observations of homing and straying in marine organisms based on traditional Eulerian approaches
may fail to resolve dispersal kernels or be unable to differentiate homing from invariant local
residency, The roles of ...
Multilocus Genotyping Assays for Single Nucleotide Polymorphism-Based Subtyping of Listeria monocytogenes Isolates
(2008-12)
Listeria monocytogenes is responsible for serious invasive illness associated with consumption
of contaminated food and places a significant burden on public health and the agricultural economy.
We recently developed a ...
