Population consequences of climate change through effects on functional traits of lentic brown trout in the sub-Arctic
Climate-induced plasticity in functional traits has received recent attention due to the immense importance phenotypic variation plays in population level responses. Here, we explore the efect of diferent climate-change scenarios on lentic populations of a freshwater ectotherm, the brown trout (Salm...

Climate-induced plasticity in functional traits has received recent attention due to the immense importance phenotypic variation plays in population level responses.

We frst parameterize models of climate variables on growth, spawning probability and fecundity. The models are utilized to inform a dynamic age-structured projection matrix, enabling long-term population viability projections under climate and population density variation.
