      Military Radiobiology provides an understanding of the sources and consequences of radiation exposure. Military personnel must develop a working knowledge of postexposure effects in order to determine points of intervention. The medical problems confronting military radiobiology include target damage, which causes decrements in normal performance, physiological injury, and impairments of the immunological-hemato... system that lead to life-threatening infectious complications. The book begins by describing the properties of nuclear weapons, including the mechanisms by which nuclear energy is stored within the nucleus, its release, and its conversion to those forces associated with nuclear weapons. This is followed by discussions of the sources, patterns, radiological effects, and management of nuclear fallout; the biological effects of exposure to ionizing radiation released by nuclear weapons; and effects of radiation on the immune system, gastrointestinal physiology, and cardiovascular function. Subsequent chapters cover the diagnosis, triage, and treatment of radiation-associated injuries; internal contamination with radionuclides; radioprotective drugs; psychological reactions to nuclear confrontation; and the response to a nuclear weapon accident.

      Perspectives on Plant Competition is mainly about addressing the many different perspectives in plant competition and finding a common ground among them. Its aim is that through this common ground, new theories can be created. Encompassing 20 chapters, this book is divided into three parts. Part I, Perspectives on the Determinants of Competitive Success, consists of eight chapters. This section deals mainly on the question of determination of competitive success. Different writers put forward various definitions of competition and competitive success to shed light on the question at hand. In the second part of this book, an opposing set of views regarding the consequences of competitive interactions for the plant community structure is provided. This section emphasizes the idea that competition is not the sole force in natural communities. Each chapter in this part focuses on a certain aspect of competition as seen in different communities – across and within habitats – and systems. Part III, which comprises of four chapters, focuses on the competition within the context of interaction of plants with organisms on the other trophic levels. The chapters set forth the idea that competition depends on the impacts of herbivores, parasites, and symbionts. The concluding part of the book greatly emphasizes the need to integrate the mechanisms of competition into the framework of the entire food web.

      The Biology and Utilization of Grasses reviews current knowledge about grass biology, and it highlights the important role of grasses in human existence. It discusses many fundamental aspects of grass biology, including evolution and genetics, morphology, physiology, and ecology, with emphasis on the relationship of these basic concepts to the use of grasses for forage, turf, and rangelands. Comprised of 28 chapters, this volume begins with an overview of the evolution and genetics of the grass family, followed by a discussion on practical grass-breeding problems. The reader is also introduced to vegetative growth and development of seedlings and mature plants; the ecological aspects of grasses; soils and mineral nutrition in relation to grass growth; the effects of defoliation (moving or grazing); carbohydrate reserves; physiology of flowering; and grass seed production and culture treatments. Other chapters consider the role of polyploidy in the evolution and distribution of grasses; selection and breeding of grasses for forage and other uses; seedling vigor and seedling establishment; environmental modification for seedling establishment; the microclimate of grass communities; effects on turf grass of cultural practices in relation to microclimate; and competition within the grass community.

      Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May 1975. The symposium not only presents investigations, but also problem areas in the field of sponge biology. This book therefore shows that sponges are a very challenging and untouched subject area for future studies. This book is divided into three major parts, wherein the first part introduces and discusses sponge biology. The introduction and discussion include sponge biology principles, perspectives, and problems. The next two parts discuss cell and development biology, taxonomy, and ecology. Part 2 deals with several topics of the cellular aspect, including an analysis of reproduction in sponge populations and cytochemical studies of connective tissues in sponges. This part also looks into the cytological abnormalities in various normal and transformed cell lines. Part 3 describes the different types of sponge in their various habitats. Sponge feeding mechanisms, ecological factors controlling sponge distribution, and zoogeography of Brazilian marine Demospongiae are also discussed in this part. This book will be of important value to biology students and teachers. Specialists including zoologists, ecologists, comparative physiologists, and biologists will also benefit from this book.

      Early Brain Damage, Volume 1: Research Orientations and Clinical Observations, is the first of two volumes that provide a comprehensive overview of the many facets of research on the topic of brain damage sustained early in life. The present volume features a collection of chapters oriented toward early brain damage in human clinical populations. It is organized into four parts. Part I presents research strategies and theoretical issues, such as intermodal compensation and evolutionary considerations, relating to early brain-damage phenomena. Part II presents research on animal models of infant neuropathological conditions such as hypoxia, fetal radiation, locomotor hyperactivity, and attentional disorders. Part III is concerned with short-term and long-term neurological effects of brain damage in children, including chapters on perinatal asphyxia, behavioral consequences of cerebral insult sustained during infancy, and correlates of early generalized brain dysfunction in children. Part IV presents chapters on cerebral lateralization and higher-order functions as they are altered by early brain damage. This book was written for researchers and professionals interested in the topic of brain damage, and especially those interested in the developmental brain-damage issues emanating from laboratory animal studies and human case reports.

      The Physiology and Pharmacology of the Microcirculation, Volume 1 discusses the biochemistry, metabolism, pharmacology, and physiology of the general microcirculation. This volume is organized into nine chapters that explore the microcirculation in several organ systems, such as brain, eye, heart, and kidney. The introductory chapters treat the biochemistry of isolated elements of the microvasculature, with special emphasis on the central nervous system. These chapters also explore the microvascular element and the vascular smooth muscle, focusing on their ultrastructural characteristics, innervation, and contraction-relaxati... and the effects of both endogenous and pharmacological vasoactive substances on vascular smooth muscle. The subsequent chapters deal with the exchange mode of the microcirculation; the mechanisms involved in the regulation of transcapillary fluid exchange; and the permeability of capillaries to small and large molecules in a variety of tissues. A discussion on the control mechanisms modulating microcirculatory dynamics is also included. The remaining four chapters are organized to deal with the microcirculation process in selected organs.
