The deep ocean is home to some of the most unusual of all fishes. This book is the first Fish Physiology volume devoted to these bizarre undersea creatures. Practically every organ system is affected by the constraints imposed by benthic pressure, the absence of light, and the relatively scarce supply of both food and mates. Deep Sea Fishes demonstrates how these fishes living in extremely harsh conditions metabolize, behave, and evolve.

This book provides a comprehensive collection of timely reviews of our current understanding of the fundamental principles of nitrogen metabolism and excretion in fish. Emphasis is placed on critical assessment of how new studies impact these topics, and the articles reflect the diversity of current research approaches.

The series "Fish Physiology" recently celebrated its 50th Anniversary. In total, the editors of the series have produced a total of 47 books (several volumes have two books) that contain almost 500 chapters since the inaugural volume published in 1969. The content of the "Fish Physiology" volumes has evolved over time. The initial volumes were devoted to understanding the basic mechanisms and principles of fish physiology, with a focus on a few model species and some application to natural environmental conditions. Then, as the field better understood mechanisms, the approach was broadened to not only delve deeper into system physiology (e.g., chapters in early volumes were expanded to become books), but interspecific differences in physiology were explored, permitting a more evolutionary framework. Finally, as interspecific physiological mechanisms were further resolved, it became possible to discuss physiology in light of a changing world. Thus, physiology can now inform on conservation, sustainability and management, as exemplified with the most recent volumes. This anniversary issue celebrates the series by highlighting some of the very important early work in the field that was published in the Series. In particular, we wished to (re)introduce new researchers to this research that has stood the test of time and that shaped the field. Each re-published chapter is preceded by a short review written by experts in the field to provide an overview/introduction of each selected chapter, discuss what is particularly noteworthy or important in the particular chapter, and discuss why in their opinion this chapter has become a classic in its own right and how it has inspired the field of fish physiology today?

The Physiology of Tropical Fishes is the 21st volume of the well-known Fish Physiology series and consists of 12 chapters. The purpose of the book is to consolidate and integrate what is known about tropical fishes (marine and freshwater species). The twelve chapters focus on the physiological adaptations acquired during the evolutionary process to cope with warm and shallow hypoxic waters from tropical and neotropical hydrographic basins as well as with the intertidal and coral reef habitats which occur in abundance in tropical seas. The special characteristics of tropical fish fauna will be issued in order to explain the tropical fish radiation, which gave rise to such extreme fish diversity.
This present volume, is a voyage through the tropical region reviewing the fish diversity of the main tropical freshwater sheds, including the major tropical rivers and lakes, the major dams, and marine environments.
* State-of-the-art information on tropical fish physiology
* Written by specialists working in the Tropics
* Offers a diverse depiction of the various tropical fishes and the environment where they inhabit
* 12 innovative chapters covering a concise view of growth rate, biological rhythms, feeding plasticity, cardio-respiratory design and function, diversity of structure, and much more

This biography of Elizabeth Mantell helps to fill a major gap in the literature on church and mission in Malawi. Women missionaries have been numerous and influential. Yet, on the whole, they have done their work without seeking or receiving much in the way of public recognition. The book will hold particular interest because of the period which it covers. Much has been written about the pioneering days of missionary work in Malawi, the 1875-1914 period. The book also makes an original contribution to the story of one of the famous centres of mission work in Malawi. Ekwendeni was among the first mission stations to be established and has continued to be prominent in the work of Livingstonia Synod right up to the present day. It has had a particular orientation to medical mission, the sphere in which Elizabeth found her forte.

The basic outline of the Christmas story is so familiar we might think we have no more to learn from it. But try looking at the Christmas story through different eyes. Through the eyes of Micah and Isaiah who foretold it; Anna and Simeon who witnessed it; and Paul and John who reflected on it. Wonder anew at this amazing story of the birth of the Son of God as a baby.

First published in 1981, this book presents an original approach to an area of great importance in comparative zoology and physiology and evolutionary biology: the evolution of air breathing in vertebrates from aquatic ancestors. The subject is approached from a functional as well as an anatomical viewpoint, utilising knowledge of the physiology of extant animals to trace probable evolutionary steps. Opening with a brief summary of current views of vertebrate evolution, the authors then go on to deal with problems of oxygen transfer in water and air and the structure and function of gills and lungs. Carbon dioxide transfer in water-breathing forms is seen as being tightly coupled to an ion and acid-base regulation. The evolution of air breathing is seen as a several-stage process, beginning with the evolution of accessory air-breathing structures for oxygen uptake.
