Pinnipeds are marine mammals that include eared seals, true seals, and walruses. This book presents detailed reviews on the ecology and conservation of 10 pinniped species along the coasts and islands in Latin America, from Mexico to Chile and Argentina. Topics covered include their population dynamics, trophic ecology, reproduction, and behavior. In addition, the book addresses major conservation issues regarding climate change, interaction with fisheries, ecotourism, and other human activities.
The indiscriminate use of chemical substances in industrial processes and anthropogenic activities, have resulted in the release of these compounds into aquatic ecosystems through municipal, hospital and industrial discharges, producing various undesired effects on the environment and on species of ecological interest. These compounds, such as metals, pesticides, emerging pollutants and other substances are persistent and susceptible to biotic and/or abiotic transformations, yielding metabolites that can be more toxic than the original compounds. In this book, researchers from diverse environmental science disciplines share their experiences in countries such as Argentina, Brazil, Colombia and Mexico, and critically examine the problem of contaminants in aquatic ecosystems in Latin America, as well as the risks presented by their presence.
This book presents the facet theoretical framework as a tool for facilitating the conception of complex animal behaviour research and the design of research procedures through employing mapping sentences. Using the facet theoretical framework, this book takes a holistic view of bird behaviour. Components of bird behavior are identified and then reassembled to facilitate an understanding of the behaviour in the context of its natural occurrence. This provides new insight on both the parts of the behaviour and how these interact as a whole. The multi-faceted approach to designing, evaluating and understanding bird behavior presented offers a template that is adaptable for investigating a wide variety of avian species and different forms of behaviour. Behavioural biologists, animal and comparative psychologists, other natural and behavioural scientists, as well as students of these disciplines will find this book to be an interesting and enlightening read.
In recent years it has become increasingly clear that chemical interactions play a fundamental role in aquatic habitats and have far-reaching evolutionary and ecological consequences. A plethora of studies have shown that aquatic organisms from most taxa and functional groups respond to minute concentrations of chemical substances released by other organisms. However, our knowledge of this "chemical network" is still negligible. Chemical interactions can be divided into two larger sub-areas based on the function of the chemical substance. First, there are interactions where chemical substances are toxic to other organisms and are used as a defence against consumers (including both herbivores and predators) or a weapon against competitors (allelopathy). Second, chemical substances may be used as a source for information of the environment; for example: how can I find the optimal habitat, the best food, the nicest partner, and avoid being eaten? Aquatic organisms are able to detect and respond to extremely low concentrations of chemical cues to answer all these questions. The book aims at connecting these intriguing chemical interactions with traditional knowledge of organism interactions. Chemical Ecology of Aquatic Systems covers a wide range of studies, both plant and animal, from different geographic regions and habitats - pelagic as well as benthic. Most of the chemical interactions are similar in freshwater and marine habitats and this book therefore strives at integrating work on both systems.
It has long been claimed that addressing biodiversity loss and other environmental problems demands a better understanding of the social dimensions of conservation; nevertheless, the active participation of indigenous peoples and local communities (IPLCs) in conservation initiatives is still a challenging and somehow controversial issue. In this context, this book hopes to give voice to other perspectives related to biodiversity conservation beyond the "fortress conservation" model and emphasize one of the pillars of democracy - popular participation. It covers a wide range of environments and issues of special significance to the topic, such as the expansion of culturally constructed niches, protected areas and food security, community-based management, participatory agroforestry, productive restoration and biocultural conservation. The contents also explore the limitations and shortcomings of participatory practices in protected areas, the relationship between the global crisis of democracy and the decline of biocultural diversity, as well as present current discussions on policy frameworks and governance systems for effective participatory biodiversity conservation. In sum, this book provides a comprehensive and realistic perspective on the social dimensions of conservation based on a series of interrelated themes in participatory biodiversity conservation. The connections between biocultural conservation and the current political and economic environment are highlighted through the chapters and the book closes with a debate on ways to reconcile human welfare, environmental justice and biodiversity conservation.
This book analyzes different facets of anuran amphibian distribution in South America. We integrate alternative biological metrics employing cutting-edge methods to understand the dynamic processes underlying species distribution patterns. By using the modern biogeographic toolbox, we explore how richness gradients, phylogenetic diversity, functional diversity, and range size/endemism distribution of amphibians vary along the continent. Moreover, we present a robust proposal for priority areas for conservation of anurans in South America that maximizes representativeness of distinct biodiversity facets.
This book provides a scientific forecast of the development in aquaculture with a focus on the environmental, technological, social and economic constraints that need to be resolved to ensure sustainable development of the industry and allow the industry to be able to feed healthy seafood products to the future generations. The chapters included discuss the most critical bottlenecks of the development encompassing subjects of understanding the environmental impacts, the current state-of-art in monitoring programs and in coastal zone management, the important interactions between wild and cultured organisms including release of non-native species into the wild, the current trends within the development of aquafeeds along with human health aspects as well as the political, socio-economic and economic trends within the industry including a chapter on approaches taken by Non Governmental Organisations (NGOs) to aquaculture. Finally the last chapter provides different future scenarios of the industry based on the identified bottlenecks.
Until about 13,000 years ago, Europe and North America were home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become our cities and streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history-and our part in it-is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face an intensified replay of that great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Inspired by a passion for the lost Pleistocene giants, some scientists advocate bringing wolves back to Scotland, and elephants to America's Great Plains as stand-ins for their extinct native brethren. By reintroducing big browsers and carnivores to colder climes, they argue, we could rescue some of the planet's most endangered animals while restoring healthy prairie ecosystems. Critics, including biologists enmeshed in the struggle to restore native species see the proposal as a dangerous distraction from more realistic and legitimate conservation efforts. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.
For the first time, this book tells the Wytham story in a way that
is accessible to both scientist and general reader alike. It
provides a fascinating overview of what the Woods are like, their
history, composition (both plant and animal), and how their
wildlife has changed over time.
The Ecology of Wild Birds Diseases would present a new insight to infectious diseases from an ecological and epidemiological view. The book will help students, researchers, biologists, veterinarian and wildlife managers and conservationists to understand the complex epidemiological interactions among different factors, those that are important for occurrence and expansion of diseases; some which in turn can significantly impact other wild and domestic animal populations and human health. The purpose of the book is to serve as a reference text for understanding the complexity of diseases of wild birds bringing essential ecological and epidemiological information into one volume.
Despite the wealth of natural historical research conducted on
migration over decades, there is still a dearth of
hypothesis-driven studies that fully integrate theory and empirical
analyses to understand the causes and consequences of migration,
and a taxonomic bias towards birds in much migration research. This
book takes a comparative, integrated view of animal migration,
linking evolution with ecology and management, theory with
empirical research, and embracing all the major migratory taxa
(including human pastoralists). The scope extends beyond the target
organism to consider the ecosystem-level dynamics of migration. The
emphasis is on exciting new research avenues that are now opening
up, whether due to advances in our understanding of migration as a
biological phenomenon or through the availability of a range of new
technologies.
A two-volume set made up of 'Biology and Conservation of Wild Canids' and 'Biology and Conservation of Wild Felids'. These advanced textbooks bring together a unique network of the world's most respected and knowledgeable experts to provide a review of the biology and conservation of these families, and provide detailed case-studies from species investigations worldwide.
Introducing Biological Energetics is a novel, interdisciplinary
text that presents biological understanding in terms of general
underlying principles, treating energy as the overarching theme and
emphasizing the all-pervading influence of energy transformation in
every process, both living and non-living. Key processes and
concepts are explained in turn, culminating in a description of the
overall functioning and regulation of a living cell. The book
rounds off the story of life with a brief account of the
endosymbiotic origins of eukaryotic cells, the development of
multicellularity, and the emergence of modern plants and animals.
This book explores the history of wildlife television in post-war Britain. It revolves around the role of David Attenborough, whose career as a broadcaster and natural history filmmaker has shaped British wildlife television. The book discusses aspects of Attenborough's professional biography and also explores elements of the institutional history of the BBC-from the early 1960s, when it was at its most powerful, to the 2000s, when its future is uncertain. It focuses primarily on the wildlife 'making-of' documentary genre, which is used to trace how television progressively became a participant in the production of knowledge about nature. With the inclusion of analysis of television programmes, first-hand accounts, BBC archival material and, most notably, interviews with David Attenborough, this volume follows the development of the professional culture of wildlife broadcasting as it has been portrayed in public. It will be of interest to wildlife television amateurs, historians of British television and students in science communication.
The Arctic, the Antarctic, and the Hindu Kush-Himalayas form a trio of terrains sometimes called "the three poles". Mainly composed of rock, snow, and ice, these precious regions, which are home to many unique species such as the polar bear, the emperor penguin, and the snow leopard, contain the primary water resource of this planet and directly shape our climate. This book presents a first-ever global assessment and progressive review of the three poles and demonstrates the urgent need for their protection. Sins of the past have irrevocably harmed and threatened many of the unique qualities of these regions, and the future looks bleak with the global population forecast to reach 9 billion by 2060, and with climate change on the rise. Presented here is a wide-reaching and coherent overview of the three poles' biodiversity, habitats, and ongoing destruction. Failed protection and social targets set by the United Nations and other bodies are exposed while economic growth, unconstrained or inappropriate development, and urban sprawl are promoted unabated. Polar regions play a major role in the global agenda as they are rich in oil and other resources, marking them for contamination, overfishing, and further degradation. Tourism in the Antarctic has benefited from enlightened self-regulation, but there are signs that this is changing, too. The chapters of this book are written by experts in their fields, and their evidence leaves no doubt that we already live beyond our carrying capacity on a finite but decaying space. A global protection role model and several outlook scenarios are proposed to help set in motion polar protection priorities that are actually valid. Humanity has demonstrated through international treaties such as the Antarctic Treaty and the Madrid Protocol that we can put the interests of the planet as a whole first. This must become the norm, not the exception.
Climate change is one of the most severe dangers for mankind worldwide. Beside the temperature increase, the sea level will rise and flood wide coastal areas, which is already remarkable today. The effects will be dramatic, in particular, at coasts with low elevation gradients such as at the German coasts of the North and Baltic Sea. The impact will be not only severe for coastal people, but still more for the unique coastal ecosystems, which harbors many plant and animal species that are already endangered today. This book focuses on the coastal terrestrial ecosystems of the German North and Baltic Sea. It describes the reactions of plants and animals (i.e. spiders, carabid beetles, bees and nematodes) on the future temperature and sea level increase. The combination of field and experimental studies is unique for Europe and for many parts of the world. It not only studies the actual elevation gradients and the climatic and saline gradients from West to East, but also the historical changes to document processes at coastal ecosystems that were already passed. In contrast to many books that studied the marine processes with similar backgrounds, this book concerns the terrestrial coastal ecosystems that were overall rarely studied and, in particular, never studied under this specific viewpoint.
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.
From the world-famous expert on chimpanzees - the powerfully compelling sequel to the international bestseller IN THE SHADOW OF MAN: 'An instant animal classic' Time Equipped with little more than a notebook, binoculars, and her fascination with wildlife, Jane braved a realm of unknowns to give the world a remarkable window into humankind's closest living relatives. On the shores of Lake Tanganyika, Gombe is a community where the principal residents are chimpanzees. Through Goodall's eyes we watch as the younger chimpanzees vie for power, and how the leaders must deal with this challenge. We learn how one mother successfully rears her children, whilst another appears to doom her offspring to failure. All life is here - glorious births and heart-breaking deaths, moments of brutality, alongside the most tender displays of affection. In THROUGH A WINDOW, as Jane Goodall reveals the story of this intimately intertwined community, we are shown the parallels with human emotions laid bare. Indeed, in the mirror of chimpanzee life, we see ourselves reflected.
Amphibians are the extant descendants of the first vertebrate class
to successfully colonize terrestrial environments; hence they
occupy a unique position between fish and reptiles. Amphibian skin
provides essentially no resistance to evaporative water loss, and
consequently daily water turnover rates are an order of magnitude
greater than in other terrestrial vertebrate groups. This has led
to a suite of physiological, morphological and behavioural
adaptations that have allowed a successful terrestrial existence in
spite of this apparently spendthrift water retention
strategy.
Applied Hierarchical Modeling in Ecology: Analysis of Distribution, Abundance and Species Richness in R and BUGS, Volume Two: Dynamic and Advanced Models provides a synthesis of the state-of-the-art in hierarchical models for plant and animal distribution, also focusing on the complex and more advanced models currently available. The book explains all procedures in the context of hierarchical models that represent a unified approach to ecological research, thus taking the reader from design, through data collection, and into analyses using a very powerful way of synthesizing data.
Coastal zones are becoming increasingly topical (and politically sensitive) as they face relentless pressures from urban expansion, recreational development, and sea level rise due to climate change. This timely book provides a comprehensive introduction to the formation, dynamics, maintenance, and perpetuation of coastal sand dune systems. It describes the interactions between living organisms and the physical processes of geomorphology. A global range of examples enhance the book's international appeal. Based on the research presented in this book, simple to complex field studies and experiments could be designed at undergraduate and graduate levels to illustrate various biological principles. This accessible book is intended for a diverse audience; as an invaluable reference for researchers who study coastal dune systems and for novice researchers requiring a sound introduction to the subject. This book is suitable for both senior undergraduate and graduate students taking courses in coastal zone management, plant ecology, restoration ecology, and conservation biology, as well as the many professional ecologists and conservation biologists requiring a concise but authoritative overview of the topic. The book also will be of relevance and use to coastal managers, planners, naturalists, and anyone pursuing a greater understanding of coastal sand dunes.
Understanding of animal social and sexual evolution has seen a renaissance in recent years with discoveries of frequent infidelity in apparently monogamous species, the importance of sperm competition, active female mate choice, and eusocial behavior in animals outside the traditional social insect groups. Each of these findings has raised new questions, and suggested new answers, about the evolution of behavioral interactions among animals. This volume synthesizes recent research on the sexual and social biology of the Crustacea, one of the dominant invertebrate groups on earth. Its staggering diversity includes ecologically important inhabitants of nearly every environment from deep-sea trenches, through headwater streams, to desert soils. The wide range of crustacean phenotypes and environments is accompanied by a comparable diversity of behavioral and social systems, including the elaborate courtship and wildly exaggerated morphologies of fiddler crabs, the mysterious queuing behavior of migrating spiny lobsters, and even eusociality in coral-reef shrimps. This diversity makes crustaceans particularly valuable for exploring the comparative evolution of sexual and social systems. Despite exciting recent advances, however, general recognition of the value of Crustacea as models has lagged behind that of the better studied insects and vertebrates. This book synthesizes the state of the field in crustacean behavior and sociobiology and places it in a conceptually based, comparative framework that will be valuable to active researchers and students in animal behavior, ecology, and evolutionary biology. It brings together a group of internationally recognized and rising experts in fields related to crustacean behavioral ecology, ranging from physiology and functional morphology, through mating and social behavior, to ecology and phylogeny. Each chapter makes connections to other, non-crustacean taxa, and the volume closes with a summary section that synthesizes the contributions, discusses anthropogenic impacts, highlights unanswered questions, and provides a vision for profitable future research.
Chickadees and titmice are among the most popular birds in North
America, due in large part to their readiness to use bird feeders,
to nest in urban gardens, and even to be trained to take food from
people's hands. These attributes have also made them (and their
Eurasian tit counterparts) perhaps the most intensively studied
bird family in the world. Long-term research in Europe has yielded
some of the most comprehensive data on the impact of global warming
on the breeding ecology of birds. Chickadees have amongst the
best-studied and most complex vocal behavior of any bird species,
displaying one of the closest analogies to human sentence structure
in the animal kingdom in their familiar chick-a-dee call. The
social dominance hierarchies commonly witnessed in the form of
squabbling at winter feeders are some of most stable and closely
studied, and have huge impacts on controlling the lives of these
small birds. Their food-storing behavior, and the brain and
physiological mechanisms controlling this, has contributed
significantly to our wider understanding of spatial orientation. In
recent years, these birds have also been used as model species for
investigating topics as diverse as inter-species hybridization, the
impacts of forest fragmentation and complex systems of
communication. In short, chickadees and titmice have contributed
enormously to our understanding of a myriad of topics in ecology,
behavior and psychology. This book brings together a range of
experts from across North America who utilize chickadees or titmice
as study organisms. Each chapter reviews the latest advances in
evolution and behavioral research that have been accomplished
through the study of North AmericanParids, and compares and
contrasts this literature with research on their Eurasian
counterparts as well as other avian families. |
