Environmental factors associated with genetic and phenotypic divergence among sympatric populations of Arctic charr (Salvelinus alpinus) (2011)
Journal Article

The mechanisms by which phenotypic and genetic divergence may occur among sympatric, conspecific populations have been widely discussed but are still not well understood. Possible mechanisms include assortative mating based on morphology or variation...

Gauging weirs impede the upstream migration of adult river lamprey Lampetra fluviatilis (2011)
Journal Article

The ability of individual and groups of 30 migrating adult river lamprey Lampetra fluviatilis L. to pass a Crump or flat-v gauging weir under two discharge regimes (moderate and low) was assessed in an experimental channel. Despite repeated attempts... Read More about Gauging weirs impede the upstream migration of adult river lamprey Lampetra fluviatilis.

The influence of discharge and temperature on the ability of upstream migrant adult river lamprey (Lampetra fluviatilis) to pass experimental overshot and undershot weirs (2011)
Journal Article

The efficiencies of fish passes specifically designed and constructed to facilitate the movement of a limited number of species and life-stages past structural barriers are likely to decline as site-specific conditions shift with a changing climate....

Dietary plasticity in Arctic charr (Salvelinus alpinus) in response to long-term environmental change (2011)
Journal Article

In the face of widespread environmental change impacts, there is a need to better understand mechanisms promoting flexibility and resilience of ecosystem components to such change to inform strategies for conservation. Glacial relict species are espe... Read More about Dietary plasticity in Arctic charr (Salvelinus alpinus) in response to long-term environmental change.
