Whether you are watching an Eider soar low over the water or listening to the iconic sound of a flock of geese flying overhead, chances are you will already be familiar with many different species of ducks, geese and swans found around the UK. But can you tell a Goosander from a Red-breasted Merganser? Or confidently distinguish between a Pink-footed Goose and a Greylag Goose? The varied habitats in the British Isles provide a home to many ducks, geese and swans that live here year-round, as well as the enormous number of birds that arrive in winter. RSPB ID Spotlight Ducks, Geese and Swans is a reliable fold-out chart with illustrations of 30 of the UK's most familiar wildfowl by renowned artist Stephen Message. - Species are grouped by family and helpfully labelled to assist with identification - Artworks are shown side-by-side for quick comparison and easy reference at home or in the field - The reverse of the chart provides information on the habitats, behaviour, life cycles and diets of our ducks, geese and swans, as well as the conservation issues they are facing and how the RSPB is working to support them - Information on successful preservation campaigns of UK wetlands and how to take part in the Wetland Birds Survey is also included The ID Spotlight charts help wildlife enthusiasts identify and learn more about our most common species using accurate colour illustrations and informative, accessible text.

This is a reprint of the first revision of this classic. Originally published in 1953 as Fishery Bulletin #74 for the US Department of the Interior, Fish and Wildlife Service. The "Gulf of Maine" is defined as an area from the Nantucket Shoals and Cape Cod in the west to Cape Sable in the east. The aim of the book was to provide a handbook for the easy identification of the fishes that occur in the Gulf of Maine, with summaries of what is known about the distribution and relative abundance together with information on the life history of each species. The authors used the 150-fathom boundary as the arbitrary offshore boundary as this will exclude almost all "deep-sea" fishes, which are numerous in the basin of the open Atlantic. Combining information gleaned from the literature as well as surveys from a large number of cruises, the volume covers the Cyclostomes, cartilaginous fishes, torpedoes, skates and rays and the bony fishes. The descriptions are as non-technical as is compatible with scientific accuracy and are limited to external features that will aid in identification in the field.

"Homeostasis and Toxicology of Non-Essential Metals" synthesizes the explosion of new information on the molecular, cellular, and organismal handling of metals in fish in the past 15 years. These elements are no longer viewed by fish physiologists as "heavy metals" that kill fish by suffocation, but rather as interesting moieties that enter and leave fish by specific pathways, which are subject to physiological regulation. The metals featured in this volume are those about which there has been most public and scientific concern, and therefore are those most widely studied by fish researchers. Metals such as Ag, Al, Cd, Pb, Hg, As, Sr, and U have no known nutritive function in fish at present, but are toxic at fairly low levels.

The companion volume, "Homeostasis and Toxicology of Essential Metals, " Volume 31A, covers metals that are either proven to be or are strongly suspected to be essential in trace amounts, yet are toxic in higher doses. Metals such as Cu, Zn, Fe, Ni, Co, Se, Mo and Cr. In addition, three chapters in Volumes 31A and 31B on Basic Principles (Chapter 1, 31A), Field Studies and Ecological Integration (Chapter 9, 31A) and Modeling the Physiology and Toxicology of Metals (Chapter 9, 31B) act as integrative summaries and make these two volumes a vital set for readers.
All major essential metals of interest are covered in metal-specific chaptersEach metal-specific chapter is written by fish physiologists/toxicologists who are recognized authorities for that metalA common format is featured throughout this two volume edition

"Oryzias latipes," known as medaka, is a model organism from East Asia. Breeding of this small, egg-laying freshwater teleost fish has long been popular among hobbyists in Japan. Now, as biological science has entered the genome era, the medaka provides significant advantages that make it one of the most valuable vertebrate models: a large collection of spontaneous mutants collected over a century, the presence of highly polymorphic inbred lines established over decades, and a recently completed genome sequence. This book is the first comprehensive monograph to cover a variety of medaka research. It opens with a historical view of medaka, followed by a series of research topics in the four major areas where the medaka is increasingly important: genomics, genetics, and resources; organogenesis and disease models; germ cells, sex determination, and reproduction; and evolution. Readers will find state-of-the-art information on medaka genetics and genomics such as the first isolation of active transposons in vertebrates, the influence of chromatin structure on sequence variation, fine QTL analysis, and versatile mutants as human disease models.

Which species of sharks live within 500 nautical miles of North American shores, and what do we know about them? Jose I. Castro's The Sharks of North America is the first comprehensive book in sixty years to address these questions, and it does so with unrivaled authority and aesthetic detail.
The 135 comprehensive species accounts summarize the present knowledge. Each begins with the etymology of a species' common and scientific names, followed by the description, identifying characteristics, geographic range, biology, reproduction, location of nurseries, growth and longevity, and relation to humans. These accounts synthesize decades of research and first-hand examination of sharks collected in fisheries and research operations across the continent. They are thorough, current, and dispel many myths and misunderstandings found in the scientific and popular literature.
Each species is illustrated by one or more original profile figures in color, augmented by images of the snout, upper and lower teeth, and dermal denticles. The stunning color illustrations have been painted directly from freshly dead sharks or Castro's photographs of live or fresh specimens. Their anatomical accuracy and true-to-life coloration are unmatched. The detailed pen and ink drawings of the snout and teeth are crucial aids to species identification, as are the exquisite scanning electron microphotographs of dermal denticles.
The Sharks of North America will serve as the standard reference on sharks for the twenty-first century and is certain to become the primary source of information for anyone interested in sharks, from professional biologists and conservationists to students, informed laypersons, and fishermen."

This series of volumes represents a comprehensive and integrated treatment of reproduction in vertebrates from fishes of all sorts through mammals. It is designed to provide a readable, coordinated description of reproductive basics in each group of vertebrates as well as an introduction to the latest trends in reproductive research and our understanding of reproductive events. Whereas each chapter and each volume is intended to stand alone as a review of that topic or vertebrate group, respectively, the volumes are prepared so as to provide a thorough topical treatment across the vertebrates. Terminology has been standardized across the volumes to reduce confusion where multiple names exist in the literature, and a comprehensive glossary of these terms and their alternative names is provided.
*A complete, essential and up to date reference for research scientists working on vertebrate hormones and reproduction - and on animlals as models in human reproductive research.
*Covers the endocrinology, neuroendocrinology, physiology, behaviour and anatomy of vertebrate reproduction.
*Structured coverage of the major themes for all five vertebrate groups allows a consistent treatment for all.
*Special chapters elaborate on features specific to individual vertebrate groups and to comparative aspects, similarities and differences between them.

This cutting-edge resource includes up-to-date information on zebrafish physiology and the tools used to study it, not only as a model species for studies of other vertebrates but with application for studies of human disease and aquatic toxicology. The utility of zebrafish for physiological research is based on several key features including i) a "fully" sequenced genome, ii) rapid ( 3 month) generation times), iii) their capacity to produce large numbers of externally fertilized eggs, iv) optical transparency of embryos and larvae, and v) the applicability of reverse and forward genetics to assess gene function. Gene knockdown in embryos and the production of transgenic strains are now standard techniques being used to assess physiology. This book will be of keen interest not only to the typical readers of Fish Physiology but also to biomedical researchers, toxicologists and developmental biologists.

Evolutionary biomechanics is the study of evolution through the analysis of biomechanical systems. Its unique advantage is the precision with which physical constraints and performance can be predicted from first principles. Instead of reviewing the entire breadth of the biomechanical literature, a few key examples are explored in depth as vehicles for discussing fundamental concepts, analytical techniques, and evolutionary theory. Each chapter develops a conceptual theme, developing the underlying theory and techniques required for analyses in evolutionary biomechanics. Examples from terrestrial biomechanics, metabolic scaling, and bird flight are used to analyse how physics constrains the design space that natural selection is free to explore, and how adaptive evolution finds solutions to the trade-offs between multiple complex conflicting performance objectives. Evolutionary Biomechanics is suitable for graduate level students and professional researchers in the fields of biomechanics, physiology, evolutionary biology and palaeontology. It will also be of relevance and use to researchers in the physical sciences and engineering.

"The" "Multifunctional Gut of Fish" provides a comprehensive synthesis and an integrative overview of the range of gut functions and their implications for organismal physiology.

Birds have colonized almost every terrestrial habitat on the planet - from the poles to the tropics, and from deserts to high mountain tops. Ecological and Environmental Physiology of Birds focuses on our current understanding of the unique physiological characteristics of birds that are of particular interest to ornithologists, but also have a wider biological relevance.
An introductory chapter covers the basic avian body plan and their still-enigmatic evolutionary history. The focus then shifts to a consideration of the essential components of that most fundamental of avian attributes: the ability to fly. The emphasis here is on feather evolution and development, flight energetics and aerodynamics, migration, and as a counterpoint, the curious secondary evolution of flightlessness that has occurred in several lineages. This sets the stage for subsequent chapters, which present specific physiological topics within a strongly ecological and environmental framework. These include gas exchange, thermal and osmotic balance, 'classical' life history parameters (male and female reproductive costs, parental care and investment in offspring, and fecundity versus longevity tradeoffs), feeding and digestive physiology, adaptations to challenging environments (high altitude, deserts, marine habitats, cold), and neural specializations (notably those important in foraging, long-distance navigation, and song production).
Throughout the book classical studies are integrated with the latest research findings. Numerous important and intriguing questions await further work, and the book concludes with a discussion of methods (emphasizing cutting-edge technology), approaches, and future research directions.
