New paper: predator-prey interactions are key to predicting fish responses to climate change

A new paper by lab members suggests that predator-prey interactions will complicate species’ ability to track their climate niches poleward in warming oceans. The upshot could be less productive fisheries in a warmer world.

Former postdoc Ed Tekwa, along with James Watson (Oregon State) and Malin Pinsky, developed a spatial food-web model that considers species’ size, metabolism, preferred temperatures, and other factors. Trophic interactions (considerations of “who eats who”) are expected to hamper species’ ability to shift in response to warming temperatures. One interesting prediction of the model is that the trailing edges of top predator ranges are expected to shift slower than the ranges of their smaller prey.

The work was recently published in the Proceedings of the Royal Society B. It was also picked up by the BBC World Service (story at time: 26:30 – 29:50), WHYY, and was the subject of a Rutgers press release.
