Intertidal Fishes describes the fishes inhabiting the narrow strip of habitat between the high and low tide marks along the rocky coastlines of the world. It analyzes the specialized traits of these fishes that have adapted to living in the dynamic and challenging space where they are alternately exposed to the air and submerged in water with the ebb and flow of the tides. This book provides a comprehensive account of fishes largely overlooked in many previous studies of intertidal organisms and emphasizes how they differ from fishes living in other deeper-water habitats. Coverage includes air breathing, movements and homing, sensory systems, spawning and parental care, feeding habits, community structure, systematic relationships, distribution patterns, and the fossil record in the intertidal zone. - Written by an international team of 21 experts on intertidal fish biology - Worldwide coverage of intertidal fishes - Comprehensive phylogenetic listing of all fish families with intertidal members - Global biogeographic analysis involving over 700 species from 86 sites - Outlines field and laboratory methods pertinent to studying intertidal fishes - Thorough ecological coverage with chapters on vertical distribution, movements and homing, reproduction, feeding, and community structure - Covers the physiology of aerial and aquatic respiration, osmoregulation, and sensory systems

A wealth of information on osmotic and ionic reaulation in Estuarine and Marine Animals has been accumulated over the past decades. Beyond early studies of whole-animal responses to changes in envi­ ronmental salinities, efforts have been made later on to identify, to localize and to characterize the organs and structures responsible for the control of the characteristics of the cell's environmental fluid. When considering the problem of cell volume control in animals facing media of fluctuating salinities, we are indeed dealing with two different categories of mechanisms. A first one is concerned with the control of the osmolality of the intracellular fluid, hence with the processes directly implicated in the maintenance of cell volume and shape. They have been extensively described in several recent review papers. The second category includes the processes controllin~ the charac­ teristics of the cell's environmental fluid in order to minimize the amplitude of the osmotic shocks the cells may have to cope with upon acclimation to media of changed salinities. They are localized in particular organs and structures : the so-called "caZt-transporting" epithelia. Up to now, most of the studies on salt-transportino epithe­ lia in estuarine and marine animals used the black box approach, so that little or sometimes nothing is still known on the physiological, the biochemical and the biophysical basis of the transporting mecha­ nisms as well as on the structure-function relationships.

The need for ion and water homeostasis is common to all life. For fish, ion and water homeostasis is an especially important challenge because they live in direct contact with water and because of the large variation in the salt content of natural waters (varying by over 5 orders of magnitude). Most fish are stenohaline and are unable to move between freshwater and seawater. Remarkably, some fishes are capable of life in both freshwater and seawater. These euryhaline fishes constitute an estimated 3 to 5% of all fish species. Euryhaline fishes represent some of the most iconic and interesting of all fish species, from salmon and sturgeon that make epic migrations to intertidal mudskippers that contend with daily salinity changes. With the advent of global climate change and increasing sea levels, understanding the environmental physiology of euryhaline species is critical for environmental management and any mitigative measures. This volume will provide the first integrative review of euryhalinity in fish. There is no other book that focuses on fish that have the capacity to move between freshwater and seawater. The different challenges of salt and water balance in different habitats have led to different physiological controls and regulation, which heretofore has not been reviewed in a single volume. - Collects and synthesizes the literature covering the state of knowledge of the physiology of euryhaline fish - Provides the foundational information needed for researchers from a variety of fields, including fish physiology, conservation and evolutionary biology, genomics, ecology, ecotoxicology, and comparative physiology - All authors are the leading researchers and emerging leaders in their fields

The major new course text has been written by experienced authors to provide coverage of the Advanced Subsidiary (AS) and Advanced GCE Biology and Human Biology specifications in a single book. Advanced Biology provides clear, well-illustrated information, which will help develop a full understanding of biological structure and function and of relevant applications. The topics have been carefully organised into parts, which give a logical sequence to the book. This new text has been developed to replace the best-selling titles Biology: Principles and Processes and Biology, A Functional Approach. Features include: full-colour design with clear diagrams and photographs; up-to-date information on biotechnology, health, applied genetics and ecology; clearly written text using the latest Institute of Biology terminology; a useful summary and a bank of practice questions at the end of every chapter; support boxes help bridge the gap from GCSE or equivalent courses; extension boxes providing additional depth of content - some by guest authors who are experts in their field; and a comprehensive index so you can quickly locate information with ease. There is also a website providing additional support that you can access directly at www.advancedbiolgy.co.uk.

This volume is one of those published from the proceedings of the invited lectures to the First International Congress of Comparative Physiology and Biochemistry I organized at Liege (Belgium) in August 1984 under the auspices of the Section of Comparative Physiology and Biochemistry of the International Union of Biological Sciences. In a general foreword to these different volumes, it seems to me appropriate to consider briefly what may be the comparative approach. Living organisms, beyond the diversity of their morphological forms, have evolved a widespread range of basic solutions to cope with the different problems, both organismal and environmental with which they are faced. Soon after the turn of the century, some biologists realized that these solutions can be best comprehended in the frame work of a comparative approach integrating results of physiological and biochemical studies done at the organismic, cellular and molecular levels. The development of this approach amongst both physiologists and biochemists remained, however, extremely slow until recently.

Osmoregulation and water balance are essential topics in animal physiology. This book starts with the physical properties of water, and the influence that it has on biological design. It then looks at the effect of the environment on physiology. Finally it studies how the evolutionary history of the animal influences the solution employed.
