Individual organisms contribute to nutrient cycling in ecological systems, which is shown to be a mechanism of homeostasis at that level. The phosphorus and nitrogen cycles are used to illustrate effects of changes in populations or communities on the cycling of these nutrients. Major disturbances such as deforestation and global climate change disrupt nutrient cycles and ecological system homeostasis. Data are examined to determine effects of deforestation on nutrient cycling. Increasing atmospheric carbon dioxide and global climate change are disrupting ecological systems’ homeostasis, and several studies are used to show how this is happening, including changes in primary production, temperature and precipitation patterns. This book also discusses the role of individual species in filtering contaminants and pollutants from ecological systems.

Traces historical developments in scientific conceptions of physiology, ecology, behavior, and evolutionary biology during the mid-twentieth century Life Out of Balance focuses on a period in history when new ideas of self-regulation, adaptation, and fitness became central to a variety of biological disciplines. During the decades surrounding World War II, these ideas developed in several quite different contexts and led to greater debates about the merits of such models as applied to larger systems, including society at large. Particularly in its later cybernetic form, homeostasis seemed to provide new ways of discussing balance and regulation that avoided discredited approaches of earlier champions of vitalism and mechanism. It provided a common perspective and terminology for discussing self-regulating “systems,” whether biological, mechanical, or social. Although enormously fruitful and influential, homeostatic perspectives also generated numerous controversies when critics questioned the degree to which biological systems are characterized by balance and self-regulation. Resolving these controversies continues to be a challenge in modern biology. If natural selection constitutes the first law of biology, scientists who champion homeostasis as a theoretical model claim that it is a second law, equally important and closely related to the first. Such claims notwithstanding, homeostasis has generated a series of controversies since it was formalized by Walter Cannon in the late 1920s. Critics contended that Cannon took a too-optimistic view of life, not only ignoring pathological deviations from normality but also failing to adequately explain the ability of living things to respond adaptively to environmental challenges. Underlying these controversies was the unresolved problem of integrating physiology and other areas of functional biology with the emerging evolutionary synthesis of Mendelian genetics and Darwinian natural selection. The physiological idea of homeostasis as the adaptive “fit” between the organism and its environment and the Darwinian idea of adaptation and fitness in terms of reproductive success might seem to be complementary in an unproblematic way, but historically they have had an uneasy relationship.

The book is dedicated to the study and mathematical definition of the biogeochemical patterns of organic and inorganic matter interaction with the marine environment's radioactive and chemical components. This book describes the radioisotope and mineral exchange theory between organic and inorganic matters in the marine environment on a time scale of metabolic processes and trophic interactions. The approach is parametrically compatible with modern techniques describing the matter and energy balance in aquatic ecosystems. The criteria for assessing the ecological capacity, biogeocenoses assimilation capacity, and water masses radio capacity, which form the basis of the theory of radioisotope and mineral homeostasis of marine ecosystems, are substantiated. This book presents methods to implement sustainable development of the Black Sea's critical and recreational zones according to the marine pollution factors. This book does that by regulating the balance between the consumption of water quality resources and their reproduction as a result of natural biogeochemical processes are proposed. The book is of interest to scientists working in marine geology, marine ecology, biogeophysics, and biogeochemistry. This book is also necessary for professionals working in institutions and administrations coordinating maritime activities, environmental projects, and developing aquaculture technologies.

Homeostasis and Toxicology of Essential Metals synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses.

Deserts, whether hot or cold, are considered to be one of the most difficult environments for living systems, lacking the essential free water which ac counts for approximately 60-70% of their body mass and more than 98% of their constituent atoms {Macfarlane 1978}. Amongst vertebrates, reptiles are usually thought of as the animals most adapted or suited to such environments because of their diurnal habit, based on a need for external heat, and their ability to survive far from obvious sources of water. This impression is rein forced when one examines the composition of vertebrate faunae characteristic of deserts and arid zones: reptiles predominate and they are often the only vertebrates to be found in hyper-arid areas, such as some parts of the Sahara {Monod 1973}. I recently had occasion to examine this assumption carefully, however, and was led inexorably to the conclusion that reptiles represent a particularly successful desert group, not because of their evolution of superior adaptations, but because of their possession of a basic suite of behavioural and physiologi cal characteristics that suit them uniquely to this very resource-limited environment {Bradshaw 1986a}. These fundamental reptilian characteristics are: 1. their low rates of metabolism, compared with birds and mammals, which result in extremely low rates of resource utilisation and lead to considerable economy in the handling of water 2.
