Progress in Theoretical Biology, Volume 3 lays particular emphasis on ecology, the theory of learning systems, and the theory of the genetic code.
The book discusses the ecosystem patterns in randomly fluctuating environments; the classical and instrumental learning by neural networks; and the genetic language. The text also describes psychophysical discrimination as well as the linear systems analysis of the calcium cycle in a forested watershed ecosystem.
Biologists, ecologists, geneticists, zoologists, and cytologists will find the book invaluable.
