Book Description
This classic and highly influential text presents a uniquely comprehensive view of the field of biophysical ecology. In its analytical interpretation of the ecological responses of plants and animals to their environments, it draws upon studies of energy exchange, gas exchange, and chemical kinetics. The first four chapters offer a preliminary treatment of the applications of biophysical ecology, discussing energy and energy budgets and their applications to plants and animals, and defining radiation laws and units. Succeeding chapters concern the physical environment, covering the topics of radiation, convection, conduction, and evaporation. The spectral properties of radiation and matter are reviewed, along with the geometrical, instantaneous, daily, and annual amounts of both shortwave and longwave radiation. The book concludes with more elaborate analytical methods for the study of photosynthesis in plants and energy budgets in animals, in addition to animal and plant temperature responses. This text will prove of value to students and environmental researchers from a variety of fields, particularly ecology, agronomy, forestry, botany, and zoology.

Book Description
The study of environmental biophysics probably began earlier in man's history than that of any other science. The study of organism-environment interaction provided a key to survival and progress. Systematic study of the science and recording of experimental results goes back many hundreds of years. Ben jamin Franklin, the early American statesman, inventor, printer, and scientist studied conduction, evaporation, and radiation. One of his observations is as follows: My desk on which I now write, and the lock of my desk, are both exposed to the same temperature of the air, and have therefore the same degree of heat or cold; yet if I lay my hand successively on the wood and on the metal, the latter feels much the coldest, not that it is really so, but being a better conductor, it more readily than the wood takes away and draws into itself the fire that was in my skin. 1 Franklin probably was not the first to discover this principle, and certainly was not the last. Modem researchers rediscover this principle frequently in their own work. It is sometimes surprising how slowly progress is made. Progress in environmental biophysics, since the observa tions of Franklin and others, has been mainly in two areas: use of mathematical models to quantify rates of heat and mass transfer and use of the continuity equation that has led to energy budget analyses.

Book Description
This partially annotated bibliography contains the first 1000 references from a computerized file of literature on the global ecological implications of carbon cycles and climatic changes. Many early citations originated from the Biogeochemical Ecological Information Center established at Oak Ridge National Laboratory in 1968 and from profiles of computerized files such as Government Research Abstracts (GRA) and Biological Abstracts (BA). Later citations have been extracted from the open literature through 1978 and early 1979, from government reports and impact statements, and from profiles of GRA, BA, and the Energy Data Base of the Department of Energy Technical Information Center, Oak Ridge, Tennessee. The subject categories covered by this bibliography may be divided into two main topics: carbon cycling and climate system analysis. Volume I contains an introduction and overview. Volume 2 contains an alphabetical (by author) listing of citations. Volume 3 provides indexes for author, organization (corporate authority), keywords (or free index terms), taxonomic category, subject category, Chemical Abstracts codes, Biological Abstracts codes (crosscode), and COSATI/Weekly Government Abstracts codes concentrated with permuted title words.

Book Description
As the ecosystem-based trend in fisheries management continues to be implemented worldwide, a thorough background of this new management approach and resulting implementation strategies is needed. Ecosystem-Based Fisheries Management in the Western Pacific presents a full picture of the process changes used in switching from target species based management to EBFM, using a region that is at the forefront of this widely accepted movement. Ecosystem-Based Fisheries Management in the Western Pacific is the outgrowth of a series of three workshops convened by the Western Pacific Regional Fishery Management council. The book follows the logical approach of each workshop, beginning with an assessment of the current state of fisheries management, transitioning through the data sources and modeling systems used to advance EBFM, and ending with practical methodologies for more thorough global implementation in the future. Contributed by experts from the Pacific regions as well as the UK and Non-pacific States, this book is one of the first available compendiums on this important movement and will be applicable to fisheries scientists and researchers, fisheries managers, policy makers, and social scientists worldwide

Book Description
The exclusive role of natural ecosystems is a key factor in the maintenance of the biospheric equilibrium. The current global crisis is largely caused by their dramatic decline by 43% in the past hundred years. Ignoring the immutable laws and limitations which determine the existence of all living things in the biosphere could lead humanity to an ecological catastrophe. This book presents the ecological, demographic, economic and socio-psychological manifestations of the global crisis and outlines the immutable laws and limitations which determine the existence of all living things in the biosphere. The authors are eminently qualified to write about the problems associated with the global crisis and consider the causes behind humanity's conflict with its environment. V. Danilov-Danilian, Associate of the Russian Academy of Sciences and Russia's former Minister of the Environment, and K. Losev, professor at Moscow State university, are leading Russian ecologists and I. Reyf is a journalist who specializes in ecology and global development. Dr. Danilov-Danilian works on the economics of nature management, economic and mathematical model building, sustainable development theory and ecology. Dr Losev is the chief researcher and head of the division of the VINITI. All the authors have published numerous papers, articles and books on such subjects as glaciology, hydrology, environment studies, global change and sustainable development.
