Gene Expression and Cold Hardiness in Animals.-Publisher Marketing: Major parts of the oceans and lands of the earth are permanently, or temporarily, exposed to temperatures below ten degrees Celcius. Micro-organisms, plants and animals living under these conditions have adapted to their environments in such a way that metabolic processes, reproduction and survival strategies are optimal for their natural biotopes. This book presents knowledge of the ecology and the physiology of cold-adapted micro-organisms, plants and animals, and explains the mechanisms of cold-adaptation on the enzymatic and molecular level, including results from the first crystal structures of enzymes of cold-adapted organisms.
