An 11-year study of lake trout ( Salvelinus namaycush ), a cold-water fish, conducted at the Canadian International Institute for Sustainable Development Experimental Lakes Area found that during warmer years lake trout had reduced access to shallow water habitats, leading to a diet of relatively smaller prey and reduced growth, compared with cooler years, suggesting a link between climate change and top predators' feeding behavior and energy acquisition.
