Marine biodiversity loss due to warming and predation: UBC researcher
Date:11/28/2011

r sites where they don't normally occur, and species richness at the sites more than doubled.

"A mussel bed is kind of like an apartment complex it provides critical habitat for a lot of little plants and animals," says Harley. "The mussels make the habitat cooler and wetter, providing an environment for crabs and other small crustaceans, snails, worms and seaweed."

These findings provide a comprehensive look at the effects of warming and predation, while many previous studies on how species ranges will change due to warming assume that species will simply shift to stay in their current temperature range.

Harley says the findings show that the combined effects of warming and predation could lead to more widespread extinction than are currently predicted, as animals or plants are unable to shift their habitat ranges.

"Warming is not just having direct effects on individual species," says Harley. "This study shows that climate change can also alter interactions between species, and produce unexpected changes in where species can live, their community structure, and their diversity."
