Description / Table of Contents:
There is an increased awareness of the importance of polar regions, and their vulnerability to anthropogenic derived change. This book offers a concise but comprehensive introduction to polar ecology. The emphasis is on the organisms that dominate these environments although pollution, conservation and experimental aspects are also considered.
