The Pasoh Forest Reserve (pasoh FR) has been a leading center for international field research in the Asian tropical forest since the 1970s, when a joint research project was carried out by Japanese, British and Malaysian research teams with the cooperation of the University of Malaya (UM) and the Forest Research Institute (FRI, now the Forest Research Institute Malaysia, FRIM) under the International Biological Program (IBP). The main objective of the project was to provide basic information on the primary productivity ofthe tropical rain forest, which was thought to be the most productive of the world's ecosystems. After the IBP project, a collaborative program between the University of Malaya and the University of Aberdeen, Scotland, UK, for post-graduate training was carried out at Pasoh. Reproductive biology of so me dipterocarp trees featured in many of the findings arrived at through the program, contributing greatly to progress in the population genetics of rain forest trees. Since those research pro grams, apart of the Pasoh forest and its field research station have been managed by FRIM. In 1984, FRIM started a long-term ecological research program in Pasoh FR with the Smithsonian Tropical Research Institute (STRI) and Harvard University, establishing a 50-ha plot and enumerating and mapping all trees 1 cm or more in diameter at breast height. A recensus has been conducted every 5 years.

Views on the dynamics of tropical forests are changing rapidly with the recognition that their environment is variable on the decadal to century scale. Fluctuating climatic conditions partly determine tropical forest structure, species composition and dynamics. Tropical communities are also highly contingent in space and time with respect to site and historical factors. Tropical forests have experienced to some degree this disturbance regime in the past, but climatologists are now predicting increasingly frequent extreme events in the new century. The combination of increasing deforestation and land-use conversion by man plus an increasingly variable environment means a situation that could be very difficult to manage.

This work presents results from five years of research on microbial species in exotic and pristine locations in Asian countries, by contributors in food science, microbiology, and agricultural and environmental sciences in the UK, Japan, Singapore, Malaysia, China, Korea, and Philippines. Some microorganisms are described here for the first time. Specific topics include lactic acid bacteria in fermented foods in Southeast Asia, culture collection networks in Asia, high actinomycete diversity in the topical rainforests of Singapore, and engineering biphenyl dioxygenases to acquire wide degradation capabilities of polychlorinated biphenyls and aromatic hydrocarbons. The editor is affiliated with the Department of Microbiology at the National University of Singapore. c. Book News Inc.

This book presents a timely collection of pioneering work in the study of these diverse and fascinating ecosystems. It consists of facsimiles of papers chosen by world experts in tropical biology as the 'classics' in the field.
