Animal Physiology: An Environmental Perspective (EPUB)

Wild animals survive in a variety of complex environments; they are exposed to predictable and unpredictable changes in their particular environment on a daily or seasonal basis. However, we live through times when almost all natural environments are undergoing relatively rapid change, andmany of these changes, such as the pollution of air and water, removal of natural food sources, environment fragmentation, and climate change, are the result of human activity. Animal Physiology: an environmental perspective shows how an understanding of the physiology of animals in their naturalhabitats helps us to understand not only how and why animals evolved the way they did, but how we can act to protect at least some of them from the extreme effects of the changes affecting their environments. Part One sets the foundation for the topics covered in the remainder of the book by introducing a range of fundamental processes that are essential to life. It considers the diversity of habitats on Earth in which animals live, and examines animal groups and their evolutionary relationships. It thenexplores the different feeding strategies used by animals to obtain the energy they require to carry out all the essential functions of life, and how animals convert the chemical energy in food molecules into the energy they need to power all body functions. Finally, it explores the generalproperties of animal cells, and how animals maintain a suitable internal environment in which their cells are protected from external influences. We then examine those fundamental principles governing the main exchanges between the cells within animals, and between an animal and its environment. Parts two to four of the book explore how different organ systems – respiratory and circulatory systems, excretory organs and endocrine systems – enable animals to interact with their environment, and how environmental temperature profoundly affects the physiology of animals. Part five considers how the sensory and nervous systems provide animals with information on their internal as well as their external environment, and how they, together with the endocrine system, are involved in the control and co-ordination of muscles, reproduction, salt and water balance, and thecardio-respiratory systems.
