Frozen: community ecology in Northern Ecosystems.

1,197 views

Published on

This is an overview talk of Northern research supported by NSTP funding. The primary purpose of the talk is to highlight the importance of this funding to students in exploring important topics in high-stress ecosystems.

Important topics developed through this research and collaboration opportunities that emerged are described.

The building blocks of the forthcoming research in 2014 in Churchill, Canada are also summarized.
