Opis

The Ecology of Seashores explores the complex shore environment. It co vers the ways in which representative species have adapted to life in a constantly changing environment in terms of their interactions, the control of community structure, and how energy and materials are cycle d in different ecosystems. Written by an eminent marine biologist, thi s work emphasizes ecological processes and the use of systems analysis in understanding such processes. He gives complete coverage of the ec ology of all seashore types: rocky shores, soft shores, sandy beaches, and estuaries at an advanced level. When appropriate, the author uses the energy circuit language of symbols and diagrams developed by H.T. Odum as a basis of understanding.

Recenzje

"This unique textbook…emphasizes ecological process and systems analysis. Six chapters synthesize complex systems…adaptations to shore life, control of community structure, and energy flow and material cycling. The final chapter presents a number of ecosystem models in the energy circuit language of H.T. Odum." -American Fisheries Society
