Geographical and seasonal variability of marine plankton
secretion of gas, tissue fluids and storage of fat, to list just a few, are discussed and evaluated. Research on modern forms helps to explain the floatation devices of long perished species. As usual, the present volume is well ~lust~ted and very carefully prepared. Each article is headed by a table of contents and completed by an exhaustive list of references. Author, taxonomic and subject indices make the “Advances” a very helpful tool to the active marine biologist. The great experience of the two editors no doubt quarantees the high standard of this valuable contribution to the vast body of literature produced every year. H. FLiiGEL (Kiel, Fedeml Republic of Germany)
VARIABILITY OF PLANKTON
Geographical and Seasonal Va~~~iiity of Marine Plank ton. 2h.A. Zvereva.
(Translated from Russian by Israel Program for Scientific Traction.} Keter Publishing House, Jerusalem, 1975,303 pp., $13.25. This is volume XII of a series of publications by U.S.S.R. scientists under the general topic “Exploration of Marine Fauna”. This volume, honoring V.G. Bogorov, seeks to provide a cross section of current plankton research by Leningrad investigators. Aquaculturists will find the volume of peripheral interest only. However, zoogeographers and copepod taxonomists will find a wealth of detail concerning general aspects of net plankton catches and specific measurements of body proportions. The latter are used to illustrate species clines and interrelationships over the world oceansmhile the former demonstrate seasonal changes in abundance of plankton in different areas. While the work appears reasonably well documented and the analyses have been conducted vigorously, the articles suffer from an apparent lack of systematic sampling, i.e., the articles are the product of samples collected as a part of a routine program rather than for specific purposes. Thus, seasonal observations are a result of observations made at different times over several years while species measurements are based upon a few specimens collected from widely spaced locations. However, this is not likely to detract from the interest this book will afford the specialist. A more serious complaint from the viewpoint of the general reader is the absence of any overview which ties the articles together. The translation is coherent and free of jargon. R.J. LEBRASSEUR and J.D. FULTON (Nanaipao, B.C., Canada)
