Clearly, this topic covers a wide range of biological activities at the biochemical, physiological, individual, population and community levels. The present volume deals with the interaction of animals and environment in energetic exchang

Some species may employ either type, depending on circumstances (Muma 1966; Cloudsley-Thompson 1991). Interm

Metobolism: The Expenditure of Energy,ermogenesis and their total energy demands are reduced accordingly. Their metabolic rates are lower and a greater proportion of their food can go directly into such vital functions as activity, growth, fat storage and reproduction than is true of endotherms (birds and mammals).

Storage: The Hoarding of Energy,must be adapted to deal with episodes of food shortage and to exploit temporary abundances. One way is to reduce energy expenditure during lean times by becoming dormant (see Chap. 6). Another is to synchronize activities with heavy energy requirements, such as reproduction, with periods of peak ava
