The volumes of this classic series, now referred to simply as "Zechmeister" after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the series' inauguration in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to...

The diagnosis and identification of plant pathogens provides the basis of plant pathology and phytomedicine. The Executive Committee of the EUROPEAN FOUNDATION FOR PLANT PATHOLOGY (EFPP) had no problem to identify this actual th topic as topic for the 4th Symposium, which was held from September 8 to the 12th at the University of Bonn. It was suggested to have introductory papers and papers on actual research on recently identified topics. The development of diagnosis and pathogen identification is very important to keep plants healthy and to provide a successful and efficient disease...

Chemistry of Plant Protection, Volume 7, provides critical review articles on new aspects of herbicide resis- tance, serving the needs of research scientists, pesticide manufacturers, government regulators, agricultural practitioners.

The interdisciplinary approach so popular today is more than a matter of fashion. It is, in fact, a reflection of the recognition that a good many areas once considered ade- quately treated by one or the other of the traditional disciplines straddle the boundaries of several. Interdisciplinary research then is, by definition, a coop- erative venture by several autonomous branches of science into areas incompletely accessible to anyone of them. By stimulating cooperation among several related disciplines, such research may serve to enrich each of them; but, on the other hand, the existence of...

This international Symposium on the biology of memory was held in the Biological Research Institute at Tihany, Lake Balaton in September 1969. The meeting covered nearly all biological aspects of recent research on elementary learning and memory storage. This complex approach proved to be fruitful: the lectures, discussions, as well as the the chairmen's con- cluding remarks reflected the main problems of this most exciting, but rather controversial field of interdisciplinary research. The volume contains the thirty papers read at the Symposium, arranged in a different sequence than they had...
