This book records contributions presented at the Third Session of the EIFAC (European Inland Fisheries Advisory Commission of the Food and Agriculture Organization of the United Nations) and OlE (Office International des Epizooties) Cooperative Programme of Research on Aquaculture (COPRAQ) Fish Diseases. The session was held at the In- stitute for Zoology and Hydrobiology, Veterinary Faculty, Munich, on the 23-26 October 1979. Sponsorship of the session was by the Federal Ministry of Food Agriculture and Forest of the Federal Republic of Gennany and by the Deutsche Forschungsgemeinschaft...

Nitrogen and sulfur compounds are continuously synthetized, degraded and converted into other forms in nature. There are many similarities in the principle problems and basic mechanisms of the biology of inorganic nitrogen and sulfur. Many details are not yet understood and hence are the subject of active investigation the world over. In May, 1980, a conference was held in Bochum, Federal Republic of Germany, at which attempts were made to discuss and compare all aspects of both the nitrogen and the sulfur cycle. Lectures were given by internationally recognized experts on the physiology,...

In a number of recent biology meetings, plant growth factors have been a favorite topic. One may ask if a new colloquium devoted to the metab olism and the activities of cytokinins, considered at the molecular level, was really necessary and will add anything important to the previous contributions. As a matter of fact, the primary purpose of the organizers, of the French National Center of Scientific Research, and of the National In stitute of Agronomic Research which sponsored the colloquium was less the edition of a proceedings book than the desire to bring together a number of scientists...

Sensorimotor systems are not rigidly wired predetermined networks but rather highly plastic structures that learn and modify their entire performance in response to changes in external or internal conditions. Lesions or distortions of the system's input, which initially cause a functional disorganization, induce an active reorganization which often leads to a recovery of function. Examples of lesion-induced neural plasticity have been known for some hundred years; however, an awareness of their value as research tools is relatively new. This current interest is a consequence of rapid ly...

This book is a collection of reviews on the renal transport of organic substances. The first chapters deal with general aspects of the topic. The following articles treat the present knowledge on the renal trans port of specific compounds or classes of organic substances, whereas the fmal chapter on comparative physiology deals with the renal trans port of organic substances in non-mammalian vertebrates. The articles of this volume were presented in an abbreviated form as introductory lectures at a recent Symposium on Renal Transport of Organic Substances. This conference was organized by...

The book you are just going to read represents the greater part of the papers presented at the International Conference on Industrial and En vironmental Xenobiotics, held in Prague, 1980, and some contributions by those who could not come. The first aim of the meeting was to fol low the tradition set up by the first conference in 1977. Again, we in vited biochemists, pharmacologists, and toxicologists from both East and West, who were involved in the study of disposition, biotransforma tion, and toxicity of important kinds of industrial and environmental pollutants, to promote the exchange of...

Previous symposia on Metabolic Interconversion of Enzymes were held in 1970 (Santa Margherita-Ligure, Italy), 1971 (Rottach-Egern, Ger- many), 1973 (Seattle, USA) and 1975 (Arad, Israel). The present pub- lication reports the proceedings of the 5th International Symposium on Metabolic Interconversion of Enzymes, held in Titisee/Black Forest (Germany) from October 1st-5th, 1980. In the last few years, the number of enzymes for which control of activity by enzyme-catalyzed covalent modification, i.e., by intercon- version, is of recognized metabolic importance has increased so much that is was...

The VIIIth International Congress of the International Prirnatological Society was held from 7 through 11 July 1980 in Florence Italy, under the auspices of the host institution, the Istituto di Antropologia of the University of Florence. More than 300 papers and abstracts were pre sented either at the main Congress or in 14 pre-Congress symposia the week earlier (so scheduled to avoid conflict with either the main invited lectures or the contnbuted paper sessions). This volume consists of the contributed papers on primate evolu tionary biology, primarily functional morphology, evolution, and...

Right from the start of this century, field observations and the patient ringing of birds have made available a growing mass of data on the breeding and resting areas of migratory species and on the course, period and duration of their seasonal flights. Considered as a whole, this work on migration morphology commands admiration, and when view ed in detail it reveals fascinating insights into the extraordinary naviga tional performances of many bird species, which find their way over enormous distances. Yet only a few dozen physiologists are actively trying to answer the question of how these...
