The book presents a collection of large-scale network-modeling studies on coastal systems in Latin America. It includes a novel description of the functioning of coastal complex ecosystems and also predicts how natural and human-made disturbances percolate through the networks. Coastal areas belong to the most populated ecosystems around the globe, and are massively influenced by human impacts such as shipping, mining, fisheries, tourism, pollution and human settlements. Even though many of these activities have facilitated socio-economic development, they have also caused a significant deterioration in natural populations, communities and ecosystems worldwide. Covering coastal marine ecosystems of Latin America such as the NE and SE Pacific, NW Atlantic and Caribbean areas, it discusses the construction of quantitative (Ecopath-Ecosim-Ecospace and Centrality of Node Sets) and semi-quantitative (Loop Analysis) multispecies trophic-network models to describe and assess the impacts of natural and human interventions like pelagic and benthic fishing as well as natural events such as El Nino, and La Nina. The book also features steady state (and/or near moving equilibrium) and dynamical models to support the management of exploited organisms, and applies and quantifies macroscopic indices, based on Ascendency (Ulanowicz) and Local Stability (Levins Loop Analysis). Further, it discusses the determination of the Keystone Species Complex Index, which is a holistic extension of the classical concept of Keystone Species (Paine), offering novel strategies for conservation monitoring and management.

For thousands of years dolphins have been man's best friend in the sea. Their brain power, sociability, communication ability and altruism have been the issue of reference for myths, tales and several scientific or experimental studies. They have also inspired people to create several works of art from the ancient times until today. Ancient Greeks called dolphins "people of the sea" and considered them equal to human beings. This book discusses several topics on different species of dolphins, their natural habitat, behaviours, and conservation strategies. Some of the topics included are behaviours of botos and short-finned pilot whales; isolation of yeasts from stranded and captive dolphins in Italy; ecological stressors of the coastal bottlenose dolphin; and dolphin-assisted therapy.

Because of their enormous size, elephants have long been irresistible for kings as symbols of their eminence. In early civilizations - such as Egypt, Mesopotamia, the Indus Civilization, and China - kings used elephants for royal sacrifice, spectacular hunts, public display of live captives, or the conspicuous consumption of ivory - all of them tending toward the elephant's extinction. The kings of India, however, as Thomas R Trautmann shows in this study, found a use for elephants that actually helped preserve their habitat and numbers in the wild: war. Trautmann traces the history of the war elephant in India and the spread of the institution to the West-where elephants took part in some of the greatest wars of antiquity - and Southeast Asia (but not China, significantly), a history that spans 3,000 years and a considerable part of the globe, from Spain to Java. He shows that because elephants eat such massive quantities of food, it was uneconomic to raise them from birth. Rather, in a unique form of domestication, Indian kings captured wild adults and trained them, one by one, through millennia. Kings were thus compelled to protect wild elephants from hunters and elephant forests from being cut down. By taking a wide-angle view of human-elephant relations, Trautmann throws into relief the structure of India's environmental history and the reasons for the persistence of wild elephants in its forests.

Large ungulates in tropical forests are among the most threatened taxa of mammals. Excessive hunting, degradation of and encroachments on their natural habitats by humans have contributed to drastic reductions in wild ungulate populations in recent decades. As such, reliable assessments of ungulate-habitat relationships and the spatial dynamics of their populations are urgently needed to provide a scientific basis for conservation efforts. However, such rigorous assessments are methodologically complex and logistically difficult, and consequently many commonly used ungulate population survey methods do not address key problems. As a result of such deficiencies, key parameters related to population distribution, abundance, habitat ecology and management of tropical forest ungulates remain poorly understood. This book addresses this critical knowledge gap by examining how population abundance patterns in five threatened species of large ungulates vary across space in the tropical forests of the Nagarahole-Bandipur reserves in southwestern India. It also explains the development and application of an innovative methodology - spatially explicit line transect sampling - based on an advanced hierarchical modelling under the Bayesian inferential framework, which overcomes common methodological deficiencies in current ungulate surveys. The methods and results presented provide valuable reference material for researchers and professionals involved in studying and managing wild ungulate populations around the globe.

From Jack London to Aldo Leopold's "fierce green fire," wolves have been a central part of the American image. Many have even suggested that our national symbol, the bald eagle, be replaced with this noble creature who, like us, raises a family and is bold and loyal in protecting the pack. Brenda Peterson blends science, history, and memoir to dramatize the epic battle to restore wolves and thus the landscape and ecology of the continent. From the vicious exterminations carried out by pioneers and settlers; to the internationally celebrated triumph of the return of wolves to Yellowstone; to backlash, politics, and near-daily news of successful reintroductions, this is perhaps the most inspiring conservation story of our time. Brenda's central characters are two famous wolves: the powerful and prolific female "067," restored to Yellowstone only to be "legally" murdered, and Journey, a near-miraculous transcontinental survivor. Along with these are the scientists, ranchers, and activists who are fighting against fear, politics, greed, and scientific ignorance to bring wild wolves home to keep our environment whole.

The Last Giants explores the rapid decline of one of the world's favourite animals and the measures required to halt their extinction, through Levison Wood's time spent with elephants in Africa.

*Levison Wood's documentary series on WALKING WITH ELEPHANTS is available to watch now on Channel 4*

This book comes at a critical time. Fifty years ago, Africa was home to just over 1.3 million elephants, but by 1990 the number had halved. Meanwhile in the span of a lifetime, the human population has more than doubled.

In Levison Wood's The Last Giants, he explores the rapid decline of one of the world's favourite animals. Filled with stories from his own time spent travelling with elephants in Africa, and documenting their migration in his Channel 4 series, Walking With Elephants, the book is a passionate wake-up call for this endangered species we take for granted. The Last Giants was written to inspire us all to act - to learn more and help save the species from permanent extinction.

At the 2019 UN climate change conference, activists and delegates from groups representing Indigenous, youth, women, and labour rights were among those marching through the halls chanting "Climate Justice, People Power." In The New Climate Activism, Jen Iris Allan looks at why and how these social activists came to participate in climate change governance while others, such as those working on human rights and health, remain on the outside of climate activism. Through case studies of women's rights, labour, alter-globalization, health, and human rights activism, Allan shows that some activists sought and successfully gained recognition as part of climate change governance, while others remained marginalized. While concepts key to some social activists, including gender mainstreaming, just transition, and climate justice are common terms, human rights and health remain "fringe issues" in climate change governance. The New Climate Activism explores why and how these activists brought their issues to climate change, and why some succeeded while others did not.

Bumblebees are familiar and charismatic insects, occurring throughout much of the world. They are increasingly being used as a model organism for studying a wide range of ecological and behavioural concepts, such as social organization, optimal foraging theories, host-parasite interactions, and pollination. Recently they have become a focus for conservationists due to mounting evidence of range contractions and catastrophic extinctions with some species disappearing from entire continents (e.g. in North America). Only by improving our understanding of their ecology can we devise sensible plans to conserve them. The role of bumblebees as invasive species (e.g. Bombus terrestris in Japan) has also become topical with the growing trade in commercial bumblebee nests for tomato pollination leading to establishment of non-native bumblebees in a number of countries.
Since the publication of the first edition of the book, there have been hundreds of research papers published on bumblebees. There is clearly a continuing need for an affordable, well-illustrated, and appealing text that makes accessible all of the major advances in understanding of the behaviour and ecology of bumblebees that have been made in the last 30 years.

When biologist Brian Harvey saw a thousand fish blundering into a Brazilian dam, he asked the obvious: What's going to happen to them? The End of the River is the story of his long search for an answer. The End of the River is about people and rivers and the misuse of science. Harvey takes readers from a fisheries patrol boat on the Fraser River to the great Tsukiji fish market in Japan, with stops in the Philippines, Thailand, and assorted South American countries. Finally, in the arid outback of northeast Brazil, against a backdrop of a multi-billion dollar river project nobody seems to want, he finds a small-scale answer to his simple question. The End of the River is a journey with many companions. Some are literary, some are imaginary. But mostly they're real characters, human and otherwise: a six-foot endangered catfish, a Canadian professor with a weakness for Thai bar girls, a chain-smoking Brazilian Brunnhilde with a passion for her river, a drug-addled stick-up artist. The End of the River is about fishermen and fish farmers and even fish cops; there are scientists and shysters as well as a few Colombian narcotraficos and some very drunk, very hairy Brazilian men in thongs. Funny and sad, The End of the River is a new kind of writing about the environment, as far off the beaten track as you can get in a Land Rover driven by a female Colombian biologist whose favourite expression is "Oops - no road " "A wonderful and engaging read with a samba beat, on the plight of the planet's living waters. The End of the River is the book Nemo would write if he could. A great way to open peoples' eyes." - Thomas E. Lovejoy, President, Heinz Center for Science, Economics and the Environment

"Habitat" is probably the most common term in ecological research. Elementary school students are introduced to the term, college students study the concept in depth, hunters make their plans based on it, nature explorers chat about the different types, and land managers spend enormous time and money modifying and restoring habitats. Although a broad swath of people now have some notion of what habitat is-opening up ample opportunity for further education and conservation-the scientific community has by and large failed to define it concretely, despite repeated attempts in the literature to come to meaningful conclusions regarding what habitat is and how we should study, manipulate, and ultimately conserve it. Wildlife Habitat Conservation presents an up-to-date review of the habitat concept, provides a scientifically rigorous definition, and emphasizes how we must focus on those critical factors contained within what we call habitat. The result is a habitat concept that promises long-term persistence of animal populations. Key concepts and items in the book include: the necessity of moving away from vague and inconsistent perspectives to more rigorous and standard conceptual definitions of wildlife and their habitat; a discussion of the essential integration of population demographics and population persistence with the concept of habitat; the importance of carry over and lag effects, behavioral processes, genetics, and species interactions to our understanding of habitat; an examination of spatiotemporal heterogeneity, realized through fragmentation, disruption to eco-evolutionary processes, and alterations to plant and animal assemblages; and, an explanation of how anthropogenic effects alter population size and distribution (isolation), genetic processes, and species diversity (including exotic plants and animals). It includes advocacy of proactive conservation and management through predictive modeling, restoration, and monitoring. Each chapter is accessibly written in a style that will be welcomed by private land owners and public resource managers at local, state, and federal levels. Also ideal for undergraduate and graduate natural resource and conservation courses, the book is organized perfectly for a one semester class. Contributors:William M. Block, Kathi L. Borgmann, J.

This book presents the latest scientific views on resource use conflicts in the Arctic seas. The main areas of focus are the biological resources of Arctic seas vs. exploitation of oil and gas resources, and the conflicts in between. In addition, climate change is presented as a stressor, which both limits and facilitates the economic availability of resources in the Arctic. The book is divided into five parts. Part 1 examines Arctic ecosystems, resilience of the marine environment and possible conflicts between industrial sector and biological world. The focus of Part 2 is on transport infrastructure along the northern routes. Issues such as Arctic maritime operations, black carbon and unmanned aerial vehicles are considered. Part 3 focuses on resource use conflicts in Arctic seas and on the most recent threats in terms of Arctic oil and gas exploration, offshore logistics operations as well as transportation of oil and oil products. Discussions in Part 4 of the book are concentrated around social aspects and involvement of local communities. Tourism development, preservation of indigenous culture, engagement of communities on relevant Arctic issues, search and rescue in the cold marine environment are examples of questions raised. The book reviews Arctic-specific petroleum regulations, the state of preparedness to oil spill accidents in the region as well as the latest developments in oil spill response technologies and their limitations. Search and rescue operations are reviewed and how working in this harsh Arctic environment affects the ability of rescue technicians to perform the required technical skills. Part 5 considers the sustainability challenges arising from the marine resource exploitation. The focus is on the vulnerability of Arctic ecosystems to disturbance - both natural and anthropogenic.

As environmental problems grow larger and more pressing, conservationists have had to adapt. With a shrinking window of time to act, they are turning to broad approaches to combat continental- and global-scale crises of biodiversity loss, invasive species, and climate change. Pathways to Success—the long-awaited successor to the classic volume Measures of Success—is a modern guide to building large-scale transformative programs capable of tackling the complex conservation crises we face today. In this strikingly illustrated volume, coauthors Nick Salafsky and Richard Margoluis walk readers through fundamental concepts of effective program-level design, helping them to think strategically about project coordination, funding, and stakeholder input. Chapters in the first part of the book look at all aspects of designing and implementing large-scale conservation programs while the second part focuses on how to use data and information to manage, adapt, and learn from program strategies. In addition, the authors offer practical advice for avoiding pitfalls, such as formulaic recipes and simplistic silver-bullet solutions that can trip up otherwise well-intentioned efforts. Abundant graphics help to explain and clarify concepts presented in the text, and a glossary in the back matter defines technical terms for the reader. Pathways to Success is the definitive guide for conservation program managers and funders who want to increase the scale and effectiveness of their work combating biodiversity loss, climate change, and other pressing environmental issues.

The importance of fungal infections in both human and animals has increased over the last few decades. This book presents an overview of the different categories of fungal infections that can be encountered in animals (including lower vertebrates) originating from environmental sources with or without transmission to humans. In addition, the endemic infections with indirect transmission from the environment, the zoophilic fungal pathogens with near-direct transmission, the zoonotic fungi that can be directly transmitted from animals to humans, mycotoxicoses and antifungal resistance in animals will also be discussed. This book includes case studies and reviews the current state of knowledge on the mechanism of fungal attraction, recognition, infection, extracellular hydrolytic enzymes and pathogenesis of nematophagous fungi. The book also covers diagnostics, fungal formulations, as well as prevention methods. It discusses strategies to access the fungal pathogen groups, metagenomic analyses, genomics, secretomics, metabolomics, proteomics and transcriptomics. In addition, pathogen description, understanding, distribution and recent research results are provided.

This book provides cutting-edge scientific idea and novel concepts on the ecosystem-based approach to fisheries management. It begins by reviewing the scientific fundamentals and problems currently faced by conventional fisheries science, based on population dynamics. In turn, it reviews the theoretical basis of ecosystem dynamics, including selected ecosystem indicators. Surplus production and balanced harvests are discussed in the ecosystem dynamics context. Several ecosystem-holistic indicators are described, but particular emphasis is placed on two: the noxicline (gain in entropy due to loss of biomass) and resilience, which are expressed as ecosystem (holistic) points of reference for defining allowable harvest rates. Both biological (population) and ecosystem (holistic) points of reference are subsequently analyzed in the context of fisheries management and conservation. An adaptability concept is also discussed as a management policy for facing climate change. In closing, the concepts presented are applied to six study cases involving a range of different ecosystems and fisheries.

The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.
