Ecological And Environmental Physiology Of Amphibians

This book provides a synthesis of current research on the unique physiological characteristics of amphibians with a particular emphasis on water balance. It includes a wealth of information on ecology, phylogeny and development. The latest experimental techniques and future research directions are also considered.

Through its emphasis on recent research, its many summary tables, and its bibliography of more than 4,000 entries, this first modern, synthetic treatment of comparative amphibian environmental physiology emerges as the definitive reference for the field. Forty internationally respected experts review the primary data, examine current research trends, and identify productive avenues for future research.

Despite their diversity, amphibians and reptiles share many physiological traits, such as their dependence on external heat sources for body temperature regulation, that are of pivotal importance to their ability to cope with the environment. Considerable variation in physiological capabilities exists in these groups and often can be related to seasonal and geographic differences in environmental parameters. This book provides a comprehensive and integrative view of the interplay between physiology and behavior in amphibians and reptiles, leading to a better understanding of the subject. The book covers topics that have recently been in the spotlight for scientific research on the physiology, behavior, and conservation of amphibians and reptiles. It brings together recent information from a range of disciplines that address critical topics for understanding their biology. As these studies are scattered across articles in specialized journals, this book provides a single and expanded source summarizing such advancements. Amphibian and Reptile Adaptations to the Environment: Interplay Between Physiology and Behavior maintains a solid scientific basis for the biological topics covered. However, it presents the material in a clear and direct manner so that it is accessible even to non-biologists interested in the basic biology, behavior, and ecology of these animals as well as how these elements are connected to their conservation.

Fish have evolved to colonise almost every type of aquatic habitat and today they are a hugely diverse group of over 25,000 species. This title presents a current and comprehensive overview of fish physiology to demonstrate how living fish function in their environment.

A description of the structural and functional adaptations of the key organs such as skin, kidneys, bladder, lungs and ovaries, with special emphasis placed on physiological adaptations: water, electrolyte, nitrogen, and thermal balance and their endocrine control. One whole chapter devoted to ecological aspects covers such exciting topics as development and metamorphosis, larval competition for food resources, and reproductive strategies.

This new text provides a fresh approach to the subject of animal physiology, truly integrating comparative and environmental aspects for the first time. The book is divided into three sections: the first covers the basic principles of adaptation and problems of size and scale; the second tackles the key mechanisms in comparative physiology; and the third considers in detail how organisms (both vertebrate and invertebrate) cope with particular environments. Throughout this final section, relevant comparative aspects are given prominence in boxes so that interesting topics can be explored in greater depth. Several textbooks deal with the physiological functioning and comparative adaptations of animals, but this one is different: Includes both comparative systems physiology (basic principles and mechanisms of excretion, thermal biology, respiration, etc) and environmental physiology (problems of life in different habitats), with easy cross-reference between the two. Analyses and integrates problems and adaptations for each kind of environment: marine, seashore and estuary, freshwater, terrestrial and parasitic. For example, it explains how seashore animals survive both tidal submersion in cold salt water and exposure to warm dry air, cope with wide variations in salinity and temperature and achieve both aerial and underwater breathing. Examines mechanisms and responses beyond physiology. It analyses the costs of different types of locomotion, together with the mechanical challenges and varying sensory needs imposed by different environments. Behavioural responses to environmental challenges are considered, including the evolution of mating systems and life-history strategies, as well as responses to stresses imposed by humans. The book therefore integrates the biochemical, physiological, behavioral and ecological adaptations that allow animals to survive in particular environments. Applies an evolutionary perspective to the analysis of environmental adaptation. It introduces modern, phylogeny-based comparative methods that have become standard techniques in the analysis of evolutionary patterns. Provides modern molecular biological insights into the mechanistic basis of adaptation, and takes the level of analysis beyond the cell to the membrane, enzyme and gene. Incorporates more varied material from a wide range of animal types, with less of a focus purely on terrestrial reptiles, birds and mammals and more on the spectacularly successful strategies of invertebrates. This is a core text for modern undergraduate courses in animal physiology, comparative physiology, environmental physiology and physiological ecology. It is also suitable for the physiological components of any animal biology course, and a key resource for degree courses in environmental biology.

Mammals are the so-called "pinnacle" group of vertebrates, successfully colonising virtually all terrestrial environments as well as the air (bats) and sea (especially pinnipeds and cetaceans). How mammals function and survive in these diverse environments has long fascinated mammologists, comparative physiologists and ecologists. Ecological and Environmental Physiology of Mammals explores the physiological mechanisms and evolutionary necessities that have made the spectacular adaptation of mammals possible. It summarises our current knowledge of the complex and sophisticated physiological approaches that mammals have for survival in a wide variety of ecological and environmental contexts: terrestrial, aerial, and aquatic. The authors have a strong comparative and quantitative focus in their broad approach to exploring mammal ecophysiology. As with other books in the Ecological and Environmental Physiology Series, the emphasis is on the unique physiological characteristics of mammals, their adaptations to extreme environments, and current experimental techniques and future research directions are also considered. This accessible text is suitable for graduate level students and researchers in the fields of mammalian comparative physiology and physiological ecology, including specialist courses in mammal ecology. It will also be of value and use to the many professional mammologists requiring a concise overview of the topic.
