For over 350 million years, thousands of species of amphibians have lived on earth, but since the 1990s they have been disappearing at an alarming rate, in many cases quite suddenly and mysteriously. What is causing these extinctions? What role do human actions play in them? What do they tell us about the overall state of biodiversity on the planet? In Extinction in Our Times, James Collins and Martha Crump explore these pressing questions and many others as they document the first modern extinction event across an entire vertebrate class, using global examples that range from the Sierra Nevada of California to the rainforests of Costa Rica and the Mediterranean coast of North Africa. Joining scientific rigor and vivid storytelling, this book is the first to use amphibian decline as a lens through which to see more clearly the larger story of climate change, conservation of biodiversity, and a host of profoundly important ecological, evolutionary, ethical, philosophical, and sociological issues.

The International Bestseller ‘Somehow, the elephants got into my soul, and it became my life’s work to see them safe and happy. There was no giving up on that vision, no matter how hard the road was at times.’ Françoise Malby-Anthony is the owner of a game reserve in South Africa with a remarkable family of elephants whose adventures have touched hearts around the world. The herd’s feisty matriarch Frankie knows who’s in charge at Thula Thula, and it’s not Françoise. But when Frankie becomes ill, and the authorities threaten to remove or cull some of the herd if the reserve doesn’t expand, Françoise is in a race against time to save her beloved elephants . . . The joys and challenges of a life dedicated to conservation are vividly described in this charming and moving book. The search is on to get a girlfriend for orphaned rhino Thabo – and then, as his behaviour becomes increasingly boisterous, a big brother to teach him manners. Françoise realizes a dream with the arrival of Savannah the cheetah – an endangered species not seen in the area since the 1940s – and finds herself rescuing meerkats kept as pets. But will Thula Thula survive the pandemic, an invasion from poachers and the threat from a mining company wanting access to its land? As Françoise faces her toughest years yet, she realizes once again that with their wisdom, resilience and communal bonds, the elephants have much to teach us. 'Enthralling' – Daily Mail

NICOLA CHESTER - A visit to the rapid where she lost a cherished friend unexpectedly reignites Amy-Jane Beer’s love of rivers setting her on a journey of natural, cultural and emotional discovery. On New Year’s Day 2012, Amy-Jane Beer’s beloved friend Kate set out with a group of others to kayak the River Rawthey in Cumbria. Kate never came home, and her death left her devoted family and friends bereft and unmoored. Returning to visit the Rawthey years later, Amy realises how much she misses the connection to the natural world she always felt when on or close to rivers, and so begins a new phase of exploration. The Flow is a book about water, and, like water, it meanders, cascades and percolates through many lives, landscapes and stories. From West Country torrents to Levels and Fens, rocky Welsh canyons, the salmon highways of Scotland and the chalk rivers of the Yorkshire Wolds, Amy-Jane follows springs, streams and rivers to explore tributary themes of wildness and wonder, loss and healing, mythology and history, cyclicity and transformation. Threading together places and voices from across Britain, The Flow is a profound, immersive exploration of our personal and ecological place in nature.

The role of non-native species in their new environments is one of the central issues in conservation biology and ecology today. This book presents a comprehensive evolutionary exploration of the complex and dynamic interactions between introduced species and native ones, and shows that non-native species can bring useful and important contributions to novel ecosystems. Based on a wide variety of examples and case studies, a strong case is made for a more positive and objective approach to non-native species and a greater appreciation of the valuable ecosystem services they provide.

Mutualisms, interactions between two species that benefit both of them, have long captured the public imagination. Their influence transcends levels of biological organization from cells to populations, communities, and ecosystems. Mutualistic symbioses were crucial to the origin of eukaryotic cells, and perhaps to the invasion of land. Mutualisms occur in every terrestrial and aquatic habitat; indeed, ecologists now believe that almost every species on Earth is involved directly or indirectly in one or more of these interactions. Mutualisms are essential to the reproduction and survival of virtually all organisms, as well as to nutrient cycles in ecosystems. Furthermore, the key ecosystem services that mutualists provide mean that they are increasingly being considered as conservation priorities, ironically at the same time as the acute risks to their ecological and evolutionary persistence are increasingly being identified. This volume, the first general work on mutualism to appear in almost thirty years, provides a detailed and conceptually-oriented overview of the subject. Focusing on a range of ecological and evolutionary aspects over different scales (from individual to ecosystem), the chapters in this book provide expert coverage of our current understanding of mutualism whilst highlighting the most important questions that remain to be answered. In bringing together a diverse team of expert contributors, this novel text captures the excitement of a dynamic field that will help to define its future research agenda.

Over the last decade, the field of plant ecology has significantly developed and expanded, especially in research concerning the herb layer and ground vegetation of forests. This revised second edition of The Herbaceous Layer in Forests of Eastern North America accounts for that growth, presenting research that approaches the ecology of the herb layer of forests from a variety of disciplines and perspectives. The book synthesizes the research of top ecologists and biologists on herbaceous layer structure, composition, and dynamics of a variety of forest ecosystem types in eastern North America. The 2003 first edition of The Herbaceous Layer in Forests of Eastern North America was praised for containing the most extensive listing of herb-layer literature in existence. This second edition brings this material up to date, revised to include current research and data. The book incorporates quantitative data to support analyses that was previously unavailable during the publication of the first edition. Also featured are six entirely new chapters, focused on the response of the herbaceous layer to a wide variety of natural and anthropogenic disturbances. Building on the over 1,200 references and sources of the first edition, the second edition of The Herbaceous Layer in Forests of Eastern North America is an invaluable resource for plant ecologists, forest ecologists, and conservationists.

An exhilarating journey to some of the world's most stunning locales, led by one of conservation's key scientists. In 1972, Eric Dinerstein was in film school at Northwestern University, with few thoughts of nature, let alone tiger-filled jungles at the base of the Himalayas or the antelope-studded Serengeti plain. Yet thanks to some inspiring teachers and the squawk of a little green heron that awakened him to nature's fundamental wonders, Dinerstein would ultimately become a leading conservation biologist, traveling to these and other remote corners of the world to protect creatures ranging from the striking snow leopard to the homely wrinkle-faced bat. "Tigerland and Other Unintended Destinations" takes readers on Dinerstein's unlikely journey to conservation's frontiers, from early research in Nepal to recent expeditions as head of Conservation Science at the World Wildlife Fund. Along the way, each locale is brought to life by the author's vivid descriptions, amusing stories, and poetic voice. We are there as the author renews his resolve after being swept downstream on an elephant's back, tracks snow leopards in the mountains of Kashmir with a remarkable housewife turned zoologist, and finds unexpected grit in a Manhattanite donor he guides into the wildest reaches of the Orinoco River. At every turn, we meet professed and unprofessed ecologists who share Dinerstein's mission, a cast of free-spirited characters uncommonly committed to - and remarkably successful at - preserving slices of the world's natural heritage. A simple sense of responsibility, one feels, shines through all of Dinerstein's experiences: not just to marvel at what we see, but to join in efforts to sustain the planet's exquisite design. Tigerland's message is clear: individuals make all the difference; if we combine science, advocacy, and passion, ambitious visions for conservation can become reality - even against overwhelming odds.

This book also looks at the effects of stress on fish immune systems, and how color and pigmentation play into physiology and species differentiation. Biology and Physiology of Freshwater Neotropical Fish is a must-have for fish biologists and zoologists. Students in zoology, ichthyology, and fish farming will also find this book useful for its coverage of some of the world's rarest and least-known fish species.

Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.

Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series is published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world. This volume, Part 5 in the series, is concerned with Northern Europe (Luxembourg, Germany, Poland, Switzerland, Austria, Czech Republic, Slovakia, Norway, Sweden, Finland, Estonia, Latvia, Lithuania, Denmark). Each chapter has been written by experts from each country, describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites, threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climatic change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programs, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.

This book sheds light on the major functions of microbial communities in aquaculture ecosystems, showing that by recycling nutrients, degrading organic matter and preventing disease outbreaks, a variety of microbes are truly beneficial to a wide range of aquaculture industries. It discusses how deteriorating environmental quality enables some microbial strains to trigger disease, describes the development of highly sustainable tools to improve water quality, and identifies crucial factors that endanger microbial homeostasis in aquaculture ecosystems. The book also covers post-antibiotic approaches for preventing and treating opportunistic microbial infections based on harnessing environmental and fish-associated microbial communities. Furthermore, it explores how manipulating and engineering these complex microbial communities using bio-agents such as probiotics, phages, natural nutritional additives, or with fine-tuned biofilters will open the door for new ways to develop a more sustainable and cost-effective aquaculture industry. Including an accessible presentation of modern high-throughput sequencing technology to identify host-microbial interactions in aquaculture ecosystems, this book is a valuable resource for scientists, aquaculture and fishery experts, sustainability enthusiasts and scholars in the areas of biology and marine agriculture.

It discusses the organisms living in Pentepui, including algae, plants, several groups of invertebrates, birds, amphibians, reptiles, and mammals. The latter portion of the book delves into the effects of human activity and global warming on Pantepui, and current conservational efforts to combat these threats. Biodiversity of Pantepui is an important resource for researchers in ecology, biogeography, evolution, and conservation, who want to understand the biodiversity and natural history of this region, and how to help conserve and protect the Guiana Highlands from environmental and human damages.

Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.

Tracking Animal Migration with Stable Isotopes, Second Edition, provides a complete introduction to new and powerful isotopic tools and applications that track animal migration, reviewing where isotope tracers fit in the modern toolbox of tracking methods. The book provides background information on a broad range of migration scenarios in terrestrial and aquatic systems and summarizes the most cutting-edge developments in the field that are revolutionizing the way migrant individuals and populations are assigned to their true origins. It allows undergraduates, graduate students and non-specialist scientists to adopt and apply isotopes to migration research, and also serves as a useful reference for scientists. The new edition thoroughly updates the information available to the reader on current applications of this technique and provides new tools for the isotopic assignment of individuals to origins, including geostatistical multi-isotope approaches and the ways in which researchers can combine isotopes with routine data in a Bayesian framework to provide best estimates of animal origins. Four new chapters include contributions on applications to the movements of terrestrial mammals, with particular emphasis on how aspects of animal physiology can influence stable isotope values.
