Abstract
As climate change creates climatic heterogeneity across landscapes, the authors hypothesize that generalist consumers will respond by adapting their behaviour to the environment and alter food webs in predictable ways. Using existing data from diverse ecosystems, the researchers show that this behavioural modification by generalist consumers alter food web dynamics in two ways: 1) They feed in new areas where they previously didn't, or on new prey, and alter food web connections; and 2) they alter food web interaction strengths by changing their relative use of differentially altered habitats, causing changes in energy and carbon flows. By finding shared, altered behaviour in species that share traits, the authors argue that we can better understand shifting food web dynamics, and use this tool to better predict the impacts of climate change.
