New paper just out online in Global Change Biology, led by postdoc Becca Selden: functional diversity among predatory fish helps protect ecosystems from the impacts of warming. Becca showed that warming has helped make Atlantic cod a much less important predator in the Northeast U.S., but other predators (spiny dogfish, hakes) have expanded to fill its role.
On a geeky note, what’s especially interesting is that these changes in predator-prey interactions with warming are occurring even though both predators and prey are shifting their distributions as the environment changes.
