Seals quickly respond to gain and loss of habitat under climate change
Date:7/9/2009

ome.

"This illustrates the importance of understanding the behaviour and life history of a species, in order to model how it may be able to respond to rapid change."

The key factors in the expansion of the new colony were likely to be the abundant local food resource and extensive physical habitat that allowed rapid expansion after the initial founder event, and a tendency for females to return to annual breeding sites in this species.

When the ice expanded again 1,000 years ago, the seals returned to their origins but in much smaller numbers.
