Boreal Shield Watersheds: Lake Trout Ecosystems in a Changing Environment brings together the work of a renowned international group of scientists who specialize in aquatic science and environmental management. They explore the functioning of Boreal Shield ecosystems, focusing on the lake trout, the classic coldwater species of northern glaciated lakes, using it as an indicator of environmental change and as a model to measure the effectiveness of management actions. This book demonstrates how boreal waters have served as a crucible for decades of environmental research into the impacts of nutrient additions, trace contaminants, acid rain, climate change, sport fishing, invasive species, and watershed disturbances. The text builds on this substantial research legacy and explores our ability to manage human interactions with ecosystems across the vast Boreal Shield ecozone of North America, and with other important ecosystems worldwide. It also provides models and new methods of assessing the risk to and the durability of ecosystems in relation to local, regional, and global human activities. Maps and descriptions of several important long-term monitoring sites and an atlas describing more than 3,000 lake trout lakes in the region are special components of the book.

The vertebrate integument arose about 450 million years ago as an armour of dermal bony plates in small, jawless fish-like creatures, informally known as the ostracoderms. This book reviews the major changes that have occurred in the vertebrate integument from its beginnings to the present day. Critical questions concerning the origin, structure and functional biology of the bony integument are discussed and intrinsically linked to major steps in vertebrate evolution and phylogeny the origin of jaws and the origin of teeth. The discussions include the origins of mineralization of major vertebrate skeletal components such as the dermatocranium, branchial arches and vertebral column. The advances that led to the origin of modern fishes and their phylogenetic development are reviewed and include the evolution of fins and replacement of the bony plates with several types of dermal scales. The evolution of reptiles saw a major transformation of the integument, with the epidermis becoming the protective outermost layer, from which the scales arose, while the dermis lay below it.The biological significance of the newly-evolved -keratin in reptilian scales, among the toughest natural materials known, is discussed in the context of its major contribution to the great success of reptiles and to the evolution of feathers and avian flight. The dermis in many vertebrates is strengthened by layers of oppositely oriented cross-fibres, now firmly entrenched as a design principle of biomechanics. Throughout the book conventional ideas are discussed and a number of new hypotheses are presented in light of the latest developments. The long evolutionary history of vertebrates indicates that the significance of the Darwinian concept of survival of the fittest may be overstated, including in our own mammalian origins and that chance often plays a major role in evolutionary patterns. Extensive illustrations are included to support the verbal descriptions.

Biogeography is a vital component in many aspects of Primatology, including studies of evolution, speciation systematics, population genetics, and community ecology. Despite its integral position in studies of primate evolution and ecology and the broad representation of research on this subject in journals, field guides, and edited volumes on different regions of the world, Primate Biogeography is a subject that is rarely addressed as a discipline in its own right. This comprehensive source introduces the reader to Primate Biogeography as a discipline, highlights the many factors that may influence the distribution of primates, and reveals the wide range of approaches that are available to understanding the distribution of this order.

This book compiles for the first time the development of echinoderm research in Latin America. The book contains 17 chapters, one introductory, 15 country chapters, and a final biogeographic analysis. It compiles all the investigations published in international and local journals, reports, theses and other gray literature. Each chapter is composed of 7 sections: introduction describes the marine environments, and main oceanographic characteristics, followed by a history of research account divided by specific subjects. The next section addresses patterns of distribution and diversity. A specific section would explain fishery or aquaculture activities. The next sections deal with environmental and anthropogenic threats that are affecting echinoderm, and any conservation or management action. Finally, a section with conclusions, needs and new lines of research. The book will include two appendixes with species lists of all echinoderms with bathimetric data, habitat and distribution.

Based on years of field work and the examination of thousands of museum specimens, The Lizards, Crocodiles, and Turtles of Honduras is the final installment of a series of volumes by James R. McCranie documenting the amphibians and reptiles of Honduras. Thoroughly illustrated by color photographs and maps of geographic distribution, the book describes in detail 86 species of Honduran lizards, crocodilians, and turtles. Identification keys in both English and Spanish allow the ready identification of all species, and discussions of conservation status review current threats to all species. The publication of this work represents the completion of the most comprehensive and detailed study of the amphibian and reptilian faunas of any country in Latin America.

The symposium "Pacific Salmon and Their Ecosystems: Status and Future Options', ' and this book resulted from initial efforts in 1992 by Robert J. Naiman and Deanna J. Stouder to examine the problem of declining Pacific salmon (Oncorhynchus spp.). Our primary goal was to determine informational gaps. As we explored different scientific sources, state, provincial, and federal agencies, as well as non-profit and fishing organizations, we found that the information existed but was not being communicated across institutional and organizational boundaries. At this juncture, we decided to create a steering committee and plan a symposium to bring together researchers, managers, and resource users. The steering committee consisted of members from state and federal agencies, non-profit organizations, and private industry (see Acknowledgments for names and affiliations). In February 1993, we met at the University of Washington in Seattle to begin planning the symposium. The steering committee spent the next four months developing the conceptual framework for the symposium and the subsequent book. Our objectives were to accomplish the following: (1) assess changes in anadromous Pacific Northwest salmonid populations, (2) examine factors responsible for those changes, and (3) identify options available to society to restore Pacific salmon in the Northwest. The symposium on Pacific Salmon was held in Seattle, Washington, January 10-12, 1994. Four hundred and thirty-five people listened to oral presentations and examined more than forty posters over two and a half days. We made a deliberate attempt to draw in speakers and attendees from outside the Pacific Northwest.

Amphibians of North Africa is a comprehensive compilation of available data on the amphibians and reptiles found in various ecosystems across North West Africa and parts of the Mediterranean region. It is essential to identifying and understanding the ecological role of regional herpetofauna and its conservational importance. It examines the biological origins and diversity of amphibians in North Africa, along with their diverse ecosystems, including deserts, grasslands and subtropical forests. The book features detailed descriptions of the adult and larvae stages of species, such as the North African fire salamander, the common painted frog, Brongersma's toad and the Mediterranean tree frog. This book is a vital resource for herpetology and ecology students and researchers, helping them identify, understand and conserve these amphibians and reptiles in their various habitats across the North African and Mediterranean regions.

This book documents the current state of research by Chinese scientists on fish biology and fisheries and brings together manuscripts by authors from research institutions, universities and government agencies. There are papers on aquaculture, life history, genetics, marine and freshwater biology, conservation, physiology, new species descriptions, and truly amazing hypogean fishes. The information on these remarkable cave species shows how much we have yet to learn from that incredible fauna. There are papers dealing with some of the largest fishes and some of the smallest cave species. There are papers dealing with some of the most traditional forms of aquaculture and others with the most modern molecular techniques. The volume includes papers on critically threatened native fishes as well as the most common food species, such as grass carp (Ctenopharyngodon idella). The information on rare and threatened species shows how China is dealing with their endangered fishes. The information on their carp species will be invaluable to those in other countries who will either take advantage of the productive carp species in aquaculture or try to manage them as invasive species outside China. For the first time we bring together a complete overview of the state of fisheries research in China.

Dramatic changes in the environment, including habitat degradation and climate change, have focused attention on how individuals and populations respond to a shifting biotic and abiotic landscape. A critical step toward meeting this goal is a clear understanding of the capacity of individuals to defend themselves against threats. Changes in water quality and temperature have direct and indirect effects on fishes. Defensive responses can occur at many levels, from cellular to behavioral actions. The authors in this volume have attempted to provide a general view of the current state of knowledge of fish defenses with respect to pathogens, parasites, and predators, and to point out gaps where further study is needed.

These notes are intended to help undergraduates who need to understand something of behavior both for its intrinsic interest and for their future careers in medicine, biology, psychology, anthropology, veterinary medicine, and nursing. In Emory University's Biology Department, a single-semester course called Evolutionary Perspectives on Behavior is given to undergraduates. It amounts to four, not eight months of study, so a great deal of compression is essential. There are several excellent textbooks available that deal with behavioral science from different perspectives, but we have found them too compendious for use in a short course when students are so heavily burdened; it is unsatisfactory to direct them to a chapter here and there in several different books or to this or that review article and original paper. In this volume, we have tried effectively and inexpensively to put in one place what we know is needed. The topics we have selected deal with their subjects in a simple, straightforward way without being too superficial. We could not cover everything and the gaps are not entirely idiosyncratic but reflect what students are given very well in other courses. Thus, there is no mention of the physiology of the axon and synapse; learning, memory, cognition, and basic genetics are hardly touched upon because students know about these matters from elsewhere.

An acclaimed journalist seeks to understand the mysterious allure of peacocks-and in the process discovers unexpected and valuable life lessons. 2022 Carnegie Medal for Excellence Longlist Selection When Sean Flynn's neighbor in North Carolina texted "Any chance you guys want a peacock? No kidding!" he stared bewilderedly at his phone. He had never considered whether he wanted a peacock. But as an award-winning magazine writer, this kind of mystery intrigued him. So he, his wife, and their two young sons became the owners of not one but three charming yet fickle birds: Carl, Ethel, and Mr. Pickle. In Why Peacocks?, Flynn chronicles his hilarious and heartwarming first year as a peacock owner, from struggling to build a pen to assisting the local bird doctor in surgery to triumphantly watching a peahen lay her first egg. He also examines the history of peacocks, from their appearance in the Garden of Eden to their befuddling Charles Darwin to their bewitching the likes of Flannery O'Connor and Martha Stewart. And fueled by a reporter's curiosity, he travels across the globe to learn more about the birds firsthand, with stops including a Scottish castle where peacocks have resided for centuries, a southern California community tormented by a serial killer of peacocks, and a Kansas City airport hotel hosting an annual gathering of true peafowl aficionados. At turns comically absurd and deeply poignant, Why Peacocks? blends lively, insightful memoir and illuminating science journalism to answer the title's question. More than that, it offers surprising lessons about love, grief, fatherhood, and family.

This is the first ever monumental and scientific documentation of the faunal wealth of the Indian Desert state of Rajasthan, covering the species diversity, distribution and conservation status. A scholarly contribution to the field of knowledge, it provides novel and vital information on the vertebrate faunal heritage of India s largest state.

Broadly falling under the Indo-Malaya Ecozone, the three major biomes of Rajasthan include Deserts and Xeric Shrublands; Tropical and Sub-tropical Dry Broadleaf Forests and Tropical and Sub-tropical Moist Broadleaf Forests and the ecoregions thus covered are North Western Thorn Scrub Forests and the Thar Desert; Khathiar-Gir Dry Deciduous Forests and the Upper Gangtic Plains Moist Deciduous Forests, respectively. Contrary to popular belief, the well known Thar or Great Indian Desert occupies only a part of the state. Rajasthan is diagonally divided by the Aravalli mountain ranges into arid and semi-arid regions. The later has a spectacular variety of highly diversified and unique yet fragile ecosystems comprising lush green fields, marshes, grasslands, rocky patches and hilly terrains, dense forests, the southern plateau, fresh water wetlands and salt lakes.

Apart from the floral richness, there is faunal abundance from fishes to mammals. The flagship and threatened species of Tiger; Leopard; Great Indian Bustard and Lesser Florican; White-Napped Tit; Raptors; Demoiselle and Sarus Crane; Chelones; Bats; Wild Ungulates; Small Cats; Bear; Wolf; Wild Dog; Otter; Uromastyx; Giant Flying Squirrel, Gharial and Gangetic Dolphin have been described in the 45 chapters penned by top notch wildlife experts and academics. Chapters covering fossil records; conservation of biodiversity via the age old Public Science of the Desert; Anthropological Account of Communities and Tribes; socio-cultural, mythological and historical aspects of faunal conservation and the fauna in retrospect; wildlife trade; ecotourism; climate and other environmental factors like Indira Gandhi Nahar Pariyojna (IGNP) believed to have changed the ecological face of Western Rajasthan; Protected Area Network; the tiger re-introduction experiment; and community conservation are key attractions. The world famous heronry, tiger reserves, wildlife sanctuaries and some threat-ridden biodiversity rich areas shall certainly draw the attention of readers from around the world.

The last chapter highlighting issues and insights on conservation and management and initiatives and gaps in research will help researchers from India and abroad to identify potential areas of future collaborative work. The strategies suggested herein can be a powerful tool for international conservational advocacy. Supported by rare photographs and paintings, the extensive content has implications for faunal ecology in similar habitats elsewhere on the Earth.

The purposes of the present dictionary are to define the osteological and taxonomic terms referring to fishes, and to explain the rationale, both anatomical and function, of fish skeletal units, in an evolutionary and biological context. This branch of biology - fish osteology - provides a deeper insight into fish evolution, bone homologies, fish terminology, and fish taxonomy.

The grey wolf is one of the world's most polarizing and charismatic species. Respected, adored, or held in awe by many as an icon of wilderness, wolves have also sparked fear and hatred when they have come into conflict with human presence. Not surprisingly, they are one of the most intensively studied mammalian species in the wild.The World of Wolves offers a fresh and provocative look at current trends in wolf and wildlife management. Representative case studies, from geographically and culturally diverse areas of the world, highlight the existing interconnections between wolves, their prey, their habitat, their ecosystems and people, and the role of science in policy formation and wolf management. In addition, the studies involve many issues (for example, population genetics and livestock husbandry practices) that are entry points into larger aspects of ecology and evolution. This book will appeal to conservationists, scientists, wildlife managers, and anyone seeking a better understanding of wolves and their co-existence with us.

This volume, The Basal Ganglia V, is derived from proceedings of the fifth Triennial Meeting of the International Basal Ganglia Society (IBAGS). The Meeting was held from 23-26 May, 1995, at Nemuno-Sato, in the Mie Prefecture of central Japan, not far from the traditional birth place of the country. As at previous Meetings, our aim was to hear and discuss new ideas and data on the Basal Ganglia. About one hundred papers were presented, on platform or as posters. We had valuable talks, stimulating discussions, and agreeable social contacts. Although just before this Meeting, there were several unusual accidents in Japan, a big earthquake in the Kobe area, not far from the Meeting place, and toxic gas terrorism in Tokyo, some hundred participants came from Europe, the United States, and elsewhere. All through the Meeting days, we were together in a beautiful environment, surrounded by fresh green vegetation, flowers and blue sea, as has been traditional for IBAGS meetings. We spent happy and pleasant sunny days there, with superb accommodation and cuisine. Also following the traditional policy of our Society, this volume has been edited to include as many papers as possible, without any selection. New ideas and data may sometimes be controversial and still immature, but we accepted all and put them together in this volume. We hope that from these fascinating papers, further new principles of basal ganglia action might emerge in the future.

In this second edition, the authors present a thorough, advanced review of the interactions between motoneurones and muscles in vertebrates. The book discusses the significance of nerve-muscle interactions for the normal development and maintenance of the vertebrate neuromuscular system and reviews the consequences of their disruption. The plasticity of nerve-muscle interactions and the potential for repair is analyzed, as is the importance of neuromuscular activity in development. The subject is approached from a broad viewpoint and the authors integrate results from many disciplines to illustrate the significance of neuromuscular interaction for normal locomotor activity. This approach makes the book useful for clinical researchers of neuromuscular disease.

Covering all the species of birds occurring in the areas bordering the Mediterranean, this guide is illustrated throughout with stunning photographs. The regions examined cover some of the most distinctive and birdrich habitats in Europe, the Middle East and North Africa, places as popular with sun-seeking holidaymakers as they are with birders. Designed to appeal to both audiences, the guide features photographs of the region's birdlife, with concise descriptive text on facing pages. Digital manipulation of the photographs has been used to ensure a consistent depiction of light conditions, making comparisons between the images easier.

Free-living birds encounter multiple health hazards brought on by viruses, bacteria, and fungi, some which in turn can significantly impact other animal populations and human health.

This book looks in detail at the relationship of fish to the food they eat, their growth and responses to the environment. The book will be of interest to a wide range of fish biologists (including upper level students), particularly those involved with aquaculture, fish feed and the environment.

This exciting new reference offers a wealth of practical and technical information on the chemical, physical, and biological effects of intensive rearing conditions on hatchery fish, and the adverse effect these factors can have on their health and physical condition. A unique combination of theory and practical applications is presented throughout the book, providing the scientific basis for managing water quality, fish cultural procedures, and the biological interactions of the fish being produced to prevent diseases and costly production losses. The book begins with a discussion of the physiological functioning of fish under normal conditions. It then explains the interactions between fish and the chemical factors in the rearing environment, including effects of the algal toxins that currently cause serious economic losses in freshwater and marine aquaculture operations world-wide. The next chapter covers the physiological effects of common fish cultural procedures, with emphasis on crowding (density tolerance), handling, and transportation, and effects on smolt development of anadromous salmonids. This section is followed by a discussion of the stress and disease problems that can result from biological interactions between the fish themselves and between fish and facultative and obligate microbial pathogens present in the rearing environment. Emphasis is on methods of preventing stress and disease problems in this section. The book concludes by exploring the biological, physical, and chemical methods of minimizing the fish pathogen load in hatchery water supplies. Thorough and complete, this indispensable resource provides professionals in fishery, biology, aquaculture, and naturalresource management with the basic technical knowledge needed to improve management of the interactions between fish and the chemical, physical, and biological factors in the rearing environment. In addition, this book will serve as a useful text for undergraduate and graduate students enrolled in fishery, biology, and zoology.

Islands with large colonies of seabirds are found throughout the globe. Seabird islands provide nesting and roosting sites for birds that forage at sea, deposit marine nutrients on land, and physically alter these islands. Habitats for numerous endemic and endangered animal and plant species, seabird islands are therefore biodiversity hotspots with high priority for conservation.
Successful campaigns to eradicate predators (e.g., rats and cats) from seabird islands have been conducted worldwide. However, removal of predators will not necessarily lead to natural recovery of seabirds or other native species. Restoration of island ecosystems requires social acceptance of eradications, knowledge of how island food webs function, and a long-term commitment to measuring and assisting the recovery process.
This book, written collaboratively by and for ecologists and resource managers, provides the first large-scale cross-system compilation, comparison, and synthesis of the ecology of seabird island systems. Offering a new conceptual framework into which to fit the impacts of seabirds on island ecology, this is an essential resource for academics and resource managers alike.
