Book Description
The last major synthesis of our knowledge of fish migration and the underlying transport and guidance phenomena, both physical and biological, was "Fish Migration" published 16 years ago by F.R. Harden Jones (1968). That synthesis was based largely upon what could be gleaned by classical fishery-biology techni.ques, such as tagging and recapture studies, commercial fishing statistics, and netting and trapping studies. Despite the fact that Harden Jones also provided, with a good deal of thought and speculation, a theoretical basis for studying the various aspects of fish migration and migratory orientation, progress in this field has been, with a few excepti.ons, piecemeal and more disjointed than might have been expected. Thus we welcomed the approach from the NATO Marine Sciences Programme Panel and the encouragement from F.R. Harden Jones to develop a proprosal for, and ultimately to organize, a NATO Advanced Research Institute (ARI) on mechanisms of fish migration. Substantial progress had been made with descriptive, analytical and predictive approaches to fish migration since the appearance of "Fish ~ligration." Both because of the progress and the often conflicting results of research, we felt that the time was again right and the effort justified to synthesize and to critically assess our knowledge. Our ultimate aim was to identify the gains and shortcomings and to develop testable hypotheses for the next decade or two.

Book Description
This comprehensive study is concerned with the solid rocks, the seas and oceans, our enveloping atmosphere, the soil and the “green mantle” of natural vegetation—as they interrelate in man’s physical environment. The text is illustrated with many photographs and specially-drawn maps and diagrams.

Book Description
THE "LITTLE ICE AGE": LOCAL AND GLOBAL PERSPECTIVES P. D. JONES and K. R. BRIFFA Climatic Research Unit, University of East Anglia, Norwich, NR4 7TJ, UK. This volume of Climatic Change is devoted to the study of the climate of the last 1000 years, with a major emphasis on the last few centuries. The timespan encompasses what has been referred to as the "Little Ice Age" (Bradley, 1992). This term was originally coined by glaciologists, with reference to the most recent major glacial advance of the Holocene (Bradley and Jones, 1993). Although other such advances in different parts of the world may not have been synchronous, the term "Little Ice Age" has come to be associated with the period of a widespread foreward movement of European glaciers between about 14 50 to 1850, as well as with relatively cooler temperatures. The issue of whether or not this concept is appropriate, is a major theme of many of the papers included in this volume.
