Population niche breadth and individual trophic specialisation of fish along a climate-productivity gradient

Data supporting Sánchez-Hernández et al. “Population
niche breadth and individual trophic specialisation of fish along a
climate-productivity gradient” (Reviews in Fish Biology and Fisheries).

The database includes information about environmental
gradients (temperature, precipitation, and nutrients), lake morphometry
(visibility, depth, and area), fish communities (richness, competition, and
predation), prey availability (richness and density) and feeding (population
niche breadth and individual trophic specialisation) for four native fish
species from 35 subarctic lakes along a marked climate-productivity gradient
corresponding to future climate change predictions.
