Surveying an area dense with conflicting observations and ideas, this volume vividly depicts the current state of knowledge as well as the great diversity of opinion in the field of population ecology. Ten papers by outstanding authorities focus on three main issues-the effects of environment and population density on population dynamics, the influence of animal behavior on population growth, and the possibilities of genetic feedback or short-term evolutionary change in control of animal populations. An incisive introduction by the editor establishes a frame of reference and supplies succinct resolutions of some of the important controversies dealt with in these pages.
Choosing from a vast literature that has been polemical, often confusing, and at times acrimonious, the book offers several classic arguments that clarify the functional, statistical, and evolutionary aspects of the relationship of population density to population growth. M. E. Solomon lays the groundwork for the ensuing debate by classifying the terms and relevant concepts of "density-dependence" as they apply to population dynamics. Other probing articles questions whether the density of animal populations is actually regulated by particular mechanisms or by random chance, provide counterexamples of the regulation of animal numbers, and explore effects of population density on the growth rates of various animal populations.
Aside from the negative effects or responses of the environment, including hazardous weather and food shortages, increasing evidence shows that a definite social or behavioral regulation may result from the interaction of individuals or groups within the animal population. This concept, ignored by some ecologists and considered universal by others, is discussed by several of the contributors. Perhaps the most noteworthy proponent of the idea that "social regulation" is for the "purpose" of preventing overpopulation and consequent destruction of resources is V. C. Wynne-Edwards. His paper outlines a theory that has stimulated wide discussion and caused reevaluation of many established views.

Some of the most exciting recent advances in animal behaviour have occurred at the interface between that subject and the study of evolution. This book, written by experts in this area, illustrates how the profound changes in our understanding of evolution have influenced behavioural research. Its chapters span both studies of how behaviour itself has evolved, dealing with topics such as comparative studies, the genetics of behaviour, speciation and the evolution of sociality and of intelligence, and also the adaptiveness which this evolution has brought about, with treatment of mating and fighting strategies, and theories of kinship and altruism. The Evolution of Behaviour should be valuable to senior undergraduate and graduate students of biology and psychology, especially those studying animal behaviour, behavioural ecology, sociobiology, evolution, ecology and environmental biology.

The Action Plan for Australian Birds 2020 is the most comprehensive review of the status of Australia's avifauna ever attempted. The latest in a series of action plans for Australian birds that have been produced every decade since 1992, it is also the largest. The accounts in this plan have been authored by more than 300 of the most knowledgeable bird experts in the country, and feature far more detail than any of the earlier plans. This volume also includes accounts of over 60 taxa that are no longer considered threatened, mainly thanks to sustained conservation action over many decades. This extensive book covers key themes that have emerged in the last decade, including the increasing impact of climate change as a threatening process, most obviously in Queensland's tropical rainforests where many birds are being pushed up the mountains. However, the effects are also indirect, as happened in the catastrophic fires of 2019/20. Many of the newly listed birds are subspecies confined to Kangaroo Island, where fire destroyed over half the population. But there are good news stories too, especially on islands where there have been spectacular successes with predator control. Such uplifting results demonstrate that when action plans are followed by action on the ground, threatened species can indeed be recovered and threats alleviated. FEATURES: Provides an overview of the conservation status of all Australian birds in 2020, including birds not yet threatened but known to be declining. Includes readily accessible status information for each species with reasons for listing and distribution maps. Outlines the actions needed for conservation and describes many birds where conservation action has allowed downlisting because they are now secure. Identifies the birds most threatened by the 2019/20 fires and draws attention to the broader role climate change is now playing in bird declines.

Offers knowledge on how to resolve human-wildlife conflicts through wildlife damage management. Provides examples of how human-wildlife conflicts can be alleviated by using an integrated approach Discusses management options including employing lethal methods; distributing supplemental food; changing the behavior of either humans or wildlife; and excluding or repelling wildlife. Backed by numerous case studies, informative side bars and full color illustrations. Uses brand new case studies to illustrate the benefits of an integrated approach to wildlife management for resolving wildlife problems.

Written as an account of the Percy Sladen Trust Expeditions to the New Hebrides in 1922-3 and 1927, this is one of the first detailed studies of the flora and fauna of these distant islands. Fully illustrated with maps and figures, this book describes the native Hebrideans and the reasons for their depopulation. The author, a biologist and zoologist, then details the insect, avian and mammalian inhabitants of the islands and their behaviors.

Originally published in 1975 Terrestrial Environments covers the zoogeography and ecology of the main terrestrial environments of the world, including fresh water habitats with emphasis on their fauna. The book also explores climate and vegetation in so far as they affect animal life. Finally, the selective influence of the environment on its fauna is discussed and, conversely, the influence of regulation, a synthesis of these interrelations. Morphological adaptations of the animals inhabiting various types of terrestrial environments are considered in relation to locomotion, feeding, and escape from enemies. Physiological adaptations are also mentioned briefly, and the adaptative importunate of diurnal and seasonal rhythms is stressed.

Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to bloom and bust, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century. "

This book is unparalleled in the comprehensive nature of the information provided on this key biotic group. It is presented by two leading global experts for this group. There is no competing text in English. Reviewers were unanimous in their view that there is an "unquestionable" need for this book. The book provides highly reliable set of data, well prepared from a content and methodological point of view, bringing much interesting information on the subject and a valuable contribution to the knowledge of ecology of the group of invertebrates.

Thermodynamics is used increasingly in ecology to understand the system properties of ecosystems because it is a basic science that describes energy transformation from a holistic view. In the last decade, many contributions to ecosystem theory based on thermodynamics have been published, therefore an important step toward integrating these theories and encouraging a more wide spread use of them is to present them in one volume.
An ecosystem consists of interdependent living organisms that are also interdependent with their environment, all of which are involved in a constant transfer of energy and mass within a general state of equilibrium or dis-equilibrium. Thermodynamics can quantify exactly how "organized" or "disorganized" a system is - an extremely useful to know when trying to understand how a dynamic ecosystem is behaving.
A part of the Environmental and Ecological (Math) Modeling series, Thermodynamics and Ecology is a book-length study - the first of its kind - of the current thinking on how an ecosystem can be explained and predicted in terms of its thermodynamical behavior. After the introductory chapters on the fundamentals of thermodynamics, the book explains how thermodynamic theory can be specifically applied to the "measurement" of an ecosystem, including the assessment of its state of entropy and enthalpy. Additionally, it will show economists how to put these theories to use when trying to quantify the movement of goods and services through another type of complex living system - a human society.

Feeding Ecology in Apes and Other Primates focuses on evolutionary perspectives of the complex interactions between the environment, food sources, physiology and behaviour in primates. This highly interdisciplinary volume provides a benchmark to assess dietary alterations that affected human evolution by putting the focus on the diet of hominid primates. It also offers a new perspective on the behavioural ecology of the last common ancestor by integrating corresponding information from both human and non-human primates. The potential of innovations of applied biotechnology are also explored to set new standards for future research on feeding ecology, and new information on feeding ecology in humans, apes and other primates is synthesized to help refine or modify current models of socioecology. By taking a comparative view, this book will be interesting to primatologists, anthropologists, behavioural ecologists and evolutionary biologists who want to understand better non-human primates, and the primate that is us.

Coastal Ecosystem Processes, written by the renowned marine scientist Daniel Alongi, describes how pelagic and benthic food webs, from beaches and tidal flats to the continental edge, process energy and matter. This volume focuses on recent advances and new developments on how food webs are closely intertwined with the geology, chemistry, and physics of coastal seas. Dr. Alongi presents a process-functional approach as a way of understanding how the energetics of coastal ecosystems rely not only on exchanges within and between food chains, but how such functions are influenced by terrigenous and atmospheric processes.
There is a need for documentation and an awareness of just how necessary, yet delicate, is the interplay of biological and physical forces between coastal ocean, land, and the atmosphere. Marine scientists today need to make informed management decisions about sustainable development and conservation of these fragile ecosystems. Coastal Ecosystem Processes provides present and future marine scientists the latest coastal ecosystem information to make the right decisions concerning the ecology of our oceans.

DIRECTLY APPLIES TO LIFE ON LAND SDG and CLIMATE CHANGE SDG. International organizations such as the Intergovernmental Panel on Climate Change (IPPC), World Health Organization, Food and Agriculture Organization and World Organization for Animal Health have all reminded us that health impacts of climate change will become some of societies' greatest challenges. How we respond or adapt to climate change will have profound implications for people, animals, biodiversity, economies and ecosystems today as well as in the future. The book provides, in one easy reference, all of the information Animal Health practitioners need from defining the climate change concept, providing science-based evidence of climate change degradation of animal (ecosystem) health and successful mitigation and reversal strategies. Despite being arguably the most important challenges of the 21st century, engagement, and leadership from the animal health sector on climate change remains hard to find. This book attempts to support animal health professionals by providing information, knowledge, and experiences they can use to remedy this situation. There is no other book that covers anything like the proposed subject matter to this level of completeness and detail. The publishing of a text of this nature could help erode the power of the climate denialism lobby, shifting the debate and allowing mitigation efforts to gain higher priority. The tone of the book has an understated sense of urgency, leaning slightly toward presenting as a 'Manual for the apocalypse'. This has potential to be a benchmark publication. The text not only defines climate change but takes a proactive approach with intervention and corrective action examples: each chapter ends with suggestions on teachable and actionable ideas that could be used to mobilize concepts and information provided into education or advocacy. In this way, the book not only brings key ideas, principles and information to understand the implications for climate change for animal health, but will help translate the book's offerings into education and intervention. Teachers and researchers could use this one-of-a-kind book to frame a course or seminar series heightening student career engagement and stewardship of a more sustainable and healthier planet.

In Britain and Ireland there are about ten times more species of solitary bee than bumblebee and honeybee combined, yet the solitary bees tend to be ignored and we know much less about them. They are a fascinating, attractive and diverse group that can be found easily in a wide range of habitats, both urban and rural, and they are important as pollinators. Solitary bees provides an introduction to the natural history, ecology and conservation of solitary bees, together with an easy-to-use key to genera. Chapters cover: Diversity and recognition; Bee lives; Cuckoos in the nest; Bees and flowers; The conservation of solitary bees; Approaches to practical work; Keys to the genera of bees of the British Isles - Females and Males; and References and further reading.

Until now, information on mammals in South Asia has never been brought together on a single platform providing all inclusive knowledge on the subject. This book is the most up to date comprehensive resource on the mammalian diversity of South Asia. It offers information on the diversity, distribution and status of 504 species of terrestrial and aquatic mammals found in Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka. This work is unique being the first of its kind that deals with diversity and distribution at the subspecies level. The book is divided in to three chapters. Chapter 1 introduces the subject and takes off from the recent works on mammals at the global level, provides an historical perspective on mammal studies in South Asia and concludes with a note on recent phylogenetic changes at supraordinal levels. Chapter 2 summarizes the information on the diversity of South Asian Mammals, provides analysis by country of mammalian diversity (supported by data in tabular form) dealing with species richness, endemism and possibly occurring species, separate analysis for each country with details on endemic and threatened species, extinct mammals, domestic mammals, and finally the IUCN status of mammals with special emphasis on threatened mammals. Chapter 3 is a comprehensive checklist that provides information oneach species, including its scientific name, type details, standardized English name, synonyms, subspecies, distribution and comments on taxonomic status. Country wise listings and analysis of species richness with emphasis on subspecies distribution Most of the analysis is supported by data in tabular forms for better understanding Notes on extinct and domesticated mammals as well as their IUCN Red List Status with criteria for such status A very comprehensive bibliography that would help readers track down specific literature

Human-Animal Studies is a burgeoning multidisciplinary enterprise. Human-Animal Studies places the relationships humans have with other animals, and the relations other animals have with humans, at the centre of scholarly enquiry, artistic practice, and political critique. It draws from, and engages with, subjects across the social sciences, the humanities, and beyond, including anthropology, archaeology, art, biological sciences, cultural studies, environmental studies, ethology, geography, gender studies, history, literary studies, philosophy, religious studies, science and technology studies, sociology, and visual culture. As research in and around Human-Animal Studies blossoms as never before, this new four-volume collection from Routledge's Critical Concepts in the Social Sciences series meets the need for an authoritative reference work to make sense of a rapidly growing and ever more complex corpus of literature. Edited by two leading scholars, the collection gathers foundational and canonical work, together with innovative and cutting-edge applications and interventions. In particular, the editors have fully incorporated masterworks from South America, Asia, and Africa to capture a truly global diversity of perspectives. With a full index, together with a comprehensive introduction, newly written by the editors, which places the collected material in its historical and intellectual context, Human-Animal Studies is an essential work of reference. The collection will be particularly useful as an essential database allowing scattered and often fugitive material to be easily located. It will also be welcomed by scholars and students as a crucial tool permitting rapid access to less familiar-and sometimes overlooked-texts.

Freshwater ecosystems have the greatest species diversity per unit area and many endangered species. This book shows that, rather than being a marginal part of terrestrial protected area management, freshwater conservation is central to sustaining biodiversity. It focuses on better practices for conserving inland aquatic ecosystems in protected areas, including rivers, wetlands, peatlands, other freshwater and brackish ecosystems, and estuaries. The authors define inland aquatic ecosystems, showing just how diverse and widespread they are. They examine the principles and processes that are essential for the conservation of freshwater ecosystems and aquatic species. Major categories of threats to freshwater ecosystems and the flow-on implications for protected area design are described. Practical case studies are used to illustrate principles and practices applied around the world. Specific management needs of the main types of freshwater ecosystems are considered, as well as the management of freshwaters in the broader landscape, showing how natural resource governance processes can be harnessed to better manage freshwater biodiversity. The book offers commentary on how to adapt freshwater conservation practices to climate change and ends with an insightful synthesis.

Insects have evolved very unique and interesting tactics using chemical signals to survive. Chemical ecology illustrates the working of the biological network by means of chemical analyses. Recent advances in analytical technology have opened the way to a better understanding of the more complicated and abyssal interactions of insects with other organisms including plants and microbes. This book covers recent research on insects and chemical communications and presents the current status about challenges faced by chemical ecologists for the management of pests in agriculture and human health.

On the Track of Unknown Animals presents evidence for the existence of numerous other large animals which have been reported by local people, but which have not yet been identified and described by science. The still 'hidden' animals presented here include the man-faced creatures of Southeast Asia, the living fossils of Oceania, the reported giant sloth and still unknown apes of South America, stories of mammoths still ranging over the Siberian taiga, as well as descriptions of many as yet unexplained strange creatures of the African jungles. A current topic of leading interest in cryptozoology is the accumulating body of evidence that Neanderthal Man - a relative of modern man but a separate species from Homo sapiens - almost surely lived simultaneously with modern man into historic times, and is probably still living in remote jungles and mountain fastnesses of the Asian Continent.

Mathematical Models of Plant-Herbivore Interactions addresses mathematical models in the study of practical questions in ecology, particularly factors that affect herbivory, including plant defense, herbivore natural enemies, and adaptive herbivory, as well as the effects of these on plant community dynamics. The result of extensive research on the use of mathematical modeling to investigate the effects of plant defenses on plant-herbivore dynamics, this book describes a toxin-determined functional response model (TDFRM) that helps explains field observations of these interactions. This book is intended for graduate students and researchers interested in mathematical biology and ecology.

Prepared as a tribute to Donald A. Riley, the essays that appear here are representative of a research area that has loosely been classified as animal cognition -- a categorization that reflects a functionalist philosophy that was prevalent in Riley's laboratory and that many of his students absorbed. According to this philosophy, it is acceptable to hypothesize that an animal might engage in complex processing of information, as long as one can operationalize evidence for such a process and the hypothesis can be presented in the context of testable predictions that can differentiate it from other mechanisms. The contributions to this volume represent the three most important areas of research in animal cognition -- stimulus representation, memory processes, and perceptual processes -- although current research has considerably blurred these distinctions.

Leaping Ahead: Advances in Prosimian Biology presents a summary of the state of prosimian biology as we move into the second decade of the 21st century. The book covers a wide range of topics, from assessments of diversity and evolutionary scenarios, through ecophysiology, cognition, behavioral and sensory ecology, to the conservation and survival prospects of this extraordinary and diverse group of mammals. The collection was inspired by an international conference in Ithala, KwaZulu-Natal, South Africa in 2007, where prosimian biologists gathered from Canada, Finland, France, Germany, India, Italy, Japan, Madagascar, South Africa, Tanzania, the United Kingdom, and the United States of America. The meeting reverberated with the passion prosimian researchers feel for their study subjects and with their deep concern for the future of prosimians in the face of ongoing habitat destruction and the burgeoning threat of bushmeat hunting. Chapters for this volume were contributed by researchers from across the globe; they attest to the diversity, vibrancy and rapid growth of prosimian biology, and to the intellectual advances that have revolutionized this field in recent years. Since its earliest beginnings, prosimian research and its resultant literature have had a strong francophone component, and researchers in many prosimian habitat countries are more comfortable reading and writing in French rather than English. French summaries of all chapters have been included. The volume is targeted at researchers, both those entering the field and established scientists, who have an interest in the biology of primates and small mammals. It is also aimed at conservation biologists seeking a deeper understanding of the faunas and conservation developments in Africa, Madagascar and Southeast Asia, and anyone who has an interest in discovering the true diversity of our order, the Primates.
