Book Description
In the last few decades there has been an ever-increasing component in most BSc Zoology degree courses of cell biology, physiology and genetics, for spectacular developments have taken place in these fields. Some aspects of biotechnology are now also being included. In order to accommodate the new material, the old zoology courses were altered and the traditional two-year basis of systematics of the animal kingdom, comparative anatomy (and physiology) and evolution, was either severely trimmed or reduced and presented in an abridged form under another title. Soon after these course alterations came the swing to modular teaching in the form of a series of shorter, separate courses, some of which were optional. The entire BSc degree course took on a different appearance and several different basic themes became possible. One major result was that in the great majority of cases taxonomy and systematics were no longer taught and biology students graduated without this basic training. We field biologists did appreciate the rising interest in ecology and environ mental studies, but at the same time lamented the shortage of taxonomic skills, so that often field work was based on incorrect identifications. For years many of us with taxonomic inclinations have been bedevilled by the problem of teaching systematics to undergraduates. At a guess, maybe only 5% of students find systematics interesting. It is, however, the very basis of all studies in biology - the correct identification of the organism concerned and its relationships to others in the community.

Conservation Biological Control
Author: Pedro A. BarbosaPublisher: Elsevier
ISBN: 0080529801
Category : Nature
Languages : en
Pages : 420
Book Description
This volume is a comprehensive treatment of how the principles of ecology and conservation biology can be used to maximize biological control. Conservation Biological Control presents various means to modify or manipulate the environment to enhance the activities of natural enemies of pests. It establishes a conceptual link between ecology and the agricultural use of agents for biological control, and discusses both theoretical issues as well as practical management concerns. Certain to be interesting to ecologists and entomologists, this volume will also appeal to scientists, faculty, researchers and students interested in pest management, horticulture, plant sciences, and agriculture. - Contains chapters by an international team of leading authorities - Establishes a conceptual link between ecology and the agricultural use of agents for biological control - Discusses both theoretical issues as well as practical management concerns - Provides specific examples of how conservation principles are used to maximize the biological control of pests
