Animal Physiology: an environmental perspective (Butler Patrick (School of Biosciences University of Birmingham))(Paperback / softback) - diskuze

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 in a time when almost all natural environments are undergoing relatively rapid change, and many 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 natural habitats 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 then explores 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 general properties of animal cells, and how animals maintain a suitable internal environment in which their cells are pro
