Recommended Posts

A new study of sub-Antarctic seabirds shows that their community structure (how they co-exist and share resources) is unaffected by annual changes in availability of different types of prey, including Antarctic krill (a small shrimp-like crustacean).

The results show that even if food availability changes, the different seabird species maintain roughly the same position in the food web.
