Bücher von Gary A. Wobeser

Also during this time, waterfowl managers have become more aware of disease as a factor in population biology and there are early attempts to put numbers to "disease" in models of continental waterfowl populations.

Gary Wobeser's successful book from 1994 has been completely updated and enlarged in a new second edition. The subjects are illustrated with examples drawn from around the world, with emphasis on the special requirements involved in working with wild animals. The book draws on the author's training as a wildlife biologist.
