Book Description
The studies in the Ogawa Forest Reserve (OPR) were initiated by a group of plant ecologists and gradually expanded into a comprehensive project covering various aspects of biology, soil science, and silviculture. The project was integrated as part of the Forest Ecosystem Team under the BIO-COSMOS Program funded by the Ministry of Agriculture, Forestry and Fisheries. As the coordinators of the Forest Ecosystem Team, we are pleased that reports of the long-term studies carried out in the OFR are being published in this first volume on Japanese ecosystems in the Ecological Studies series. Scientists and researchers have made numerous contributions to the field of forest ecology during more than 10 years of studies in the OFR. Two reasons can be cited for the success of the project: scientists from various disciplines concen trated on a single target forest ecosystem, and the research continued over a rela tively long term. It is now recognized that ecological processes include compli cated mechanisms supported by interactions among organisms and large temporal variations. The researchers in the OFR project were motivated by their interest in the history of ecosystems and the interactions of diverse creatures in the forest.

Book Description
Large-scale experimentation allows scientists to test the specific responses of ecosystems to changing environmental conditions. Researchers at Oak Ridge National Laboratory together with other Federal and University scientists conducted a large-scale climatic change experiment at the Walker Branch Watershed in Tennessee, a model upland hardwood forest in North America. This volume synthesizes mechanisms of forest ecosystem response to changing hydrologic budgets associated with climatic change drivers. The authors explain the implications of changes at both the plant and stand levels, and they extrapolate the data to ecosystem-level responses, such as changes in nutrient cycling, biodiversity and carbon sequestration. In analyzing data, they also discuss similarities and differences with other temperate deciduous forests. Source data for the experiment has been archived by the authors in the U.S. Department of Energy's Carbon Dioxide Information and Analysis Center (CDIAC) for future analysis and modeling by independent investigators.

Book Description
Biodiversity is decreasing at the fastest rate in the history of the earth. The sustainable use of ecosystems allowing maintenance of biological diversity is an urgent problem that must be solved. The work featured in this book presents the results achieved by the RIHN project, together with reports on other international activities and related efforts, as ecologists, forestry scientists, environmental economists, and sociologists share in discussions of the issues.

Book Description
This book presents current knowledge of seed fate in both natural and human-disturbed landscapes, from various regions of the world. Habitats considered range from mountain and arid deserts in the temperate zone, to savanna and lowland rainforests in tropical regions of the world. Particular attention is paid to plant diversity conservation when seed removal is affected by factors such as hunting, habitat fragmentation or intensive logging. Contributors include leading scientists involved in research on seed ecology and on animal-plant relationships from the perspective of both primary and secondary seed dispersal, and predation.

Book Description
Synthesizing 40 years of ongoing ecological research, this book examines the structure, function, and dynamics of the Lamto humid savanna. From the history of the Lamto ecology station, to an overview of enivronmental conditions of the site, and examining the integrative view of energy and nutrient fluxes relative to the dynamics of the region's vegetation, this exacting work is as unique and treasured as Lamto itself.

Book Description
This book explores the relationship between cultural strategies and their biological outcomes, combining for the first time an ecosystems approach with cultural anthropological, archaeological and evolutionary behavioural concepts. Beginning with resource use and food procurement behaviour, the text examines major subsistence modes, the circumstances and dynamics of large-scale subsistence change, the effect of social differentiation on resource use and the effects of subsistence behaviour on population development and regulation.

Book Description
Forest ecosystems represent a major type ofland use in Germanyand in Europe. They provide a number of functions, or ecosystem services, beneficial to humans, namely biomass production, regulation of the water- and energy cyde, C and N sequestration, erosion control, recreation, and they act as habitat for numerous species. The stability of forest ecosystems in Europe as influenced by the deposition of air pollutants has been a matter of debate for more than 20 years. Besides atmospheric deposition, other environmental conditions affecting forest ecosystems, such as temperature, CO content of the atmosphere 2 and precipitation, have significantly changed in the past and continue to change in the future. Quantifying and predicting the effects of these changes on ecosys tem functioning are achallenge to ecosystem research and also a requirement to establish sustainable use of forest ecosystems in the future. This book summarizes results of long-term, interdisciplinary ecosystem research conducted in two forested catchments and coordinated at the Bayreuth Institute of Terrestrial Ecosystem Research (BITÖK), University of Bayreuth, Germany. It does not aim to summarize all the research of BITÖ K in the past decade, which would go far beyond the studies in these two catch ments. Instead, we concentrate here on the long-term developments in the biogeochemistry of carbon and mineral elements and on the water cyde, at both the plot and the catchment scale.

Book Description
The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.

Book Description
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.
