This book examines the biology of tuco-tucos (Ctenomys) from an evolutionary perspective. Historically, these subterranean rodents have long attracted the attention of scientists due to its remarkable chromosomes variability and rapid diversification. A wealth of knowledge on physiology, ecology, genetics, morphology, paleontology, and taxonomy has been documented in the last 70 years through numerous single publications. In this volume, expert investigators review and frame these essays with the breadth of current understanding. The collection of chapters are presented into the major topics: i) Evolution of Ctenomys, ii) Geographic Patterns, iii) Organismal Biology, and iv) Environmental Relationships. Given its scope, the book will be of interest to both students and researchers and may stimulate further research with this exciting model on a wide range of evolutionary topics.
This book aims to be a comprehensive review of the literature on the conservation genetics of the New World crocodilians, from the biological and demographical aspects of the living species to the application of molecular techniques for conservation purposes. It covers the current status of the molecular genetics applied to phylogenetics, phylogeography, diversity, kinship and mating system, and hybridization, as well its implications for decision making with regards to the conservation of these species at academic and governmental levels. This book can be used as a guide for graduate and undergraduate students to understand how conservation genetics techniques are carried out and how they can help preserve not only crocodilians but also other living species.
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.
A comprehensive guide to the calls of the 44 species of bat currently known to occur in Europe. Following on from the popular British Bat Calls by Jon Russ, this new book draws on the expertise of more than forty specialist authors to substantially update all sections, further expanding the volume to include sound analysis and species identification of all European bats. Aimed at volunteers and professional alike, topics include the basics of sound, echolocation in bats, an introduction to acoustic communication, equipment used and call analysis. For each species, detailed information is given on distribution, emergence, flight and foraging behaviour, habitat, echolocation calls - including parameters of common measurements - and social calls. Calls are described for both heterodyne and time expansion/full spectrum systems. A simple but complete echolocation guide to all species is provided for beginners, allowing them to analyse call sequences and arrive at the most likely species or group. The book also includes access to a downloadable library of over 450 calls presented as sonograms in the species sections.
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.
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 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.
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.
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.
With a new afterword, Why You Are Here: A speech on the opening of the COP26 climate summit As a young man, I felt I was out there in the wild, experiencing the untouched natural world - but it was an illusion. The tragedy of our time has been happening all around us, barely noticeable from day to day - the loss of our planet's wild places, its biodiversity. I have been witness to this decline. A Life on Our Planet contains my witness statement, and my vision for the future - the story of how we came to make this, our greatest mistake, and how, if we act now, we can yet put it right. We have the opportunity to create the perfect home for ourselves and restore the wonderful world we inherited. All we need is the will do so.
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.
This book introduces ecologists to the wonderful world of modern tools for data analysis, especially multivariate analysis. For biologists with relatively little prior knowledge of statistics, it introduces a modern, advanced approach to data analysis in an intuitive and accessible way. The book begins by reviewing some core principles in statistics, and relates common methods to the linear model, a general framework for modeling data where the response is continuous. This is then extended to discrete data using generalized linear models, to designs with multiple sampling levels via mixed models, and to situations where there are multiple response variables via model-based approaches to multivariate analysis. Along the way there is an introduction to: important principles in model selection; adaptations of the model to handle non-linearity and cyclical variables; dependence due to structured correlation in time, space or phylogeny; and design-based techniques for inference that can relax some of the modelling assumptions. It concludes with a range of advanced topics in model-based multivariate analysis relevant to the modern ecologist, including fourth corner, latent variable and copula models. Examples span a variety of applications including environmental monitoring, species distribution modeling, global-scale surveys of plant traits, and small field experiments on biological controls. Math Boxes throughout the book explain some of the core ideas mathematically for readers who want to delve deeper, and R code is used throughout. Accompanying code, data, and solutions to exercises can be found in the ecostats R package on CRAN.
The human foot is a unique and defining characteristic of our anatomy. Most primates have grasping, prehensile feet, whereas the human foot stands out as a powerful non-grasping propulsive lever that is central to our evolution as adept bipedal walkers and runners and defines our lineage. Very few books have compiled and evaluated key research on the primate foot and provided a perspective on what we know and what we still need to know. This book serves as an essential companion to "The Evolution of the Primate Hand" volume, also in the Developments in Primatology series. This book includes chapters written by experts in the field of morphology and mechanics of the primate foot, the role of the foot in different aspects of primate locomotion (including but not limited to human bipedalism), the "hard evidence" of primate foot evolution including fossil foot bones and fossil footprints, and the relevance of our foot's evolutionary history to modern human foot pathology. This volume addresses three fundamental questions: (1) What makes the human foot so different from that of other primates? (2) How does the anatomy, biomechanics, and ecological context of the foot and foot use differ among primates and why? (3) how did foot anatomy and function change throughout primate and human evolution, and why is this evolutionary history relevant in clinical contexts today? This co-edited volume, which relies on the insights of leading scholars in primate foot anatomy and evolution provides for the first time a comprehensive review and scholarly discussion of the primate foot from multiple perspectives. It is accessible to readers at different levels of inquiry (e.g., undergraduate/graduate students, postdoctoral research, other scholars outside of biological anthropology). This volume provides an all-in-one resource for research on the comparative and functional morphology and evolution of the primate foot.
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.
Feral pigeons are among the most familiar and abundant birds in the world, urban creatures living in close association with humans yet possessing the characteristics of highly adapted wild birds. However, they are seldom studied, even though the domesticated pigeon has long been one of the major bird models for laboratory research. This definitive monograph focuses on the population, biology, and behavioral ecology of feral pigeons, including a thorough listing of primary references of U.S. and European scholarly literature. Professional and amateur ornithologists, pigeon breeders, and students will find this an invaluable and fascinating study of a species that has evolved from familiar breeds of domesticated birds.
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.
This auto-translation book overviews the fish population and its research methods, help readers in understanding the concept of fish population and population identification. It divides into seven chapters according to the characteristics of the subject and the development results. Based on a systematic introduction to the basic concepts and research contents of the biology of fishery resources, the book focuses on the introduction of fish populations and research methods, life history division and early development identification, age identification and growth research, the division of sexual maturity, the determination of reproductive habits and fecundity, feeding characteristics and research methods of fish, and the mechanism of fish colony and migration. Through the study of this course, we can master the basic theory and methods of fish biology research and lay a solid foundation for future researches on fishery resources. This book can be used as a reference book for undergraduates and postgraduates who study fishery resources, as well as for those who are engaged in fishery and marine research. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content. |
