Sperm Competition and Sexual Selection presents the intricate ways in which sperm compete to fertilize eggs and how this has prompted reinterpretations of breeding behavior. This book provides a theoretical framework for the study of sperm competition, which is a central part of sexual selection. It also discusses the roles of females and the relationships between paternal care in sperm competition. The chapters focusing on taxonomic development are diverse and cover all the major animal groups, both vertebrate and invertebrate, and plants. The final chapter provides an overview discussing the relationship between sperm competition and sexual selection in terms of both function and mechanism and how these translate into species fitness. This book will be of prime interest to behaviorists, ecologists and evolutionary biologists, suggesting new avenues of research and new ways of approaching old problems.

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.

Protozoa may be found in almost every aquatic habitat, each containing dozens of species. The diversity can provide invaluable insights into the nature of the habitat. Protozoa can thus be used to illustrate biological principles. This colour guide makes the identification of individual protozoa easily accessible to students and professionals and provides information on protozoan communities found in different environments by means of a wealth of colour photomicrographs supported by original and detailed line drawings and concise text. The guide has been welcomed by professional practitioners, researchers and instructors, by graduate, undergraduate and secondary level students, in a wide range of disciplines, for its clarity in providing a logical system for learning and recognition, the first step towards understanding and using the protozoan community as a biological indicator of environmental change, pollution and contamination.

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.

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.

The relationship between systematics and ecology has recently been invigorated, and developed a long way from the "old" field of comparative biology. This change has been two-fold. Advances in phylogenetic research have allowed explicit phylogenetic hypotheses to be constructed for a range of different groups of organisms, and ecologists are now more aware that organism traits are influenced by the interaction of past and present. This volume discusses the impact of these modern phylogenetic methods on ecology, especially those using comparative methods.
Although unification of these areas has proved difficult, a number of conclusions can be drawn from the text. These include the need for a "working" bridge between evolutionary biologists using logic-based cladistic methods and those using probability-based statistical methods, for care in the selection of tree types for comparative studies and for systematists to attempt to analyse ecologically important groups.
Comparative ecologists and systematists need to come together to develop these ideas further, but this volume presents a very useful starting point for all those interested in systematics 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.

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.

How can we engage communities? What is empowerment? To what extent should the project process be participatory? How is an outsider-insider relationship handled? How do researchers negotiate with the hegemony of western cultural interpretations? How are organizational and contextual influences handled in a project? What leadership demands do such projects place on researchers? What is capacity building? What are creative leaders and creative communities? How does the researcher journey from their studio to the situation? M(2) Models and Methodologies for Community Engagement discusses key theoretical constructs - community engagement, capacity building, and community empowerment - in order to demonstrate how theory and practice are relevant to the development of forms of community involvement. The book maps the attributes of community based projects by moving beyond simply bringing people together from a variety of disciplines, and taking an approach which is transdisciplinary and applicable across cultures and genres. Here, all people - including the community - are ongoing contributors, and can freely move between their own and others' discipline-specific arenas. M(2) differs from and extends on other works in this field of practice and research, in that its transdisciplinary, collaborative approach positions the community as a particular kind of discipline to create real change in diverse locations and fields of experience. The book is in itself a model of community engagement, as the researchers have formed a community of research and practice for change, and have developed a transformative model for community engagement that is greater than the sum of its parts - hence M(2). M(2) offers a valuable resource for students, researchers, academics, practitioners, policy developers and volunteers from the fields of architecture, interior architecture, health, planning, anthropology, education, home economics, communication, political studies and development studies.

Fish - including cyclostomes, elasmobranchs, and teleosts - display a wide variety of ways of coping with the stringent conditions they encounter in the aquatic environment. This diversity is especially evident in the female genital systems where some fish spawn profligate numbers of small eggs while others develop a few yolky eggs that may receive parental care. Parental care is carried to extremes in viviparity where eggs develop within the ovary or oviducts of the mother.This volume describes the myriad ways in which fish have approached problems of reproduction - it is an amply illustrated comparative study of the microscopic structure of the female genital systems of fish.

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.

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.

This Naturalists' Handbook aims to attract more people to the study of solitary wasps by describing the ecology, distribution and natural history of these insects, including all relevant research in one convenient volume. Contents include an overview of the natural history of the solitary wasp, guidelines on identification, and advice on techniques and approaches to study. Further reading, a systematic checklist of genera and an alphabetical checklist of species and their distributions are included. Detailed keys to the identification of the species form the centre of the book and the text is accompanied by clear illustrations throughout, making this an invaluable practical guide for anyone seeking to broaden their knowledge of these fascinating, diverse creatures. Smaller, gentler and less intimidating than the black and yellow social wasps, the solitary wasps are attractive because of their bright colours and their fascinating behaviour. A female wasp will construct a nest, excavating it from wood or sand or building it from mud. She provisions the nest with prey, hunting down a suitable creature, perhaps a caterpillar or a fly, which she will paralyse before dragging it home to the nest. She lays her egg on the paralysed prey, and the larva when it hatches feeds on the prey. On a sunny day it is easy to observe the apparently purposeful behaviour of female wasps as they prepare their nests and stock them with food for the next generation. This book is a digital reprint of ISBN 0-85546-295-7 (1995). Naturalists' Handbooks encourage and enable those interested in natural history to undertake field study, make accurate identifications and to make original contributions to research.

A beautifully illustrated and thoroughly engaging cultural history of beekeeping - packed with anecdote, humour and enriching historical detail. The perfect gift. "A charming look at the history of beekeeping, from myth and folklore to our practical relationship with bees" Gardens Illustrated "An entertaining collation of bee trivia across the millennia" Daily Telegraph * Sweden's Gardening Book of the Year 2019 * Shortlisted for the August Prize 2019 * Winner of the Swedish Book Design Award for 2019 Beekeeper and garden historian Lotte Moeller explores the activities inside and outside the hive while charting the bees' natural order and habits. With a light touch she uses her encyclopaedic knowledge of the subject to shed light on humanity's understanding of bees and bee lore from antiquity to the present. A humorous debunking of the myths that have held for centuries is matched by a wry exploration of how and when they were replaced by fact. In her travels Moeller encounters a trigger-happy Californian beekeeper raging against both killer bees and bee politics, warring beekeepers on the Danish island of Laeso, and Brother Adam of Buckfast Abbey, breeder of the Buckfast queen now popular throughout Europe and beyond, as well a host of others as passionate as she about the complex world of apiculture both past and present. Translated from the Swedish by Frank Perry

This is the first ever monumental and scientific documentation of the faunal wealth of the Indian Desert state of Rajasthan. This volume, the first of two, provides background on Rajasthan and covers species diversity and distribution of fauna. A scholarly contribution to the field of knowledge, it provides novel and vital information on the vertebrate faunal heritage of India's largest state. Broadly falling under the Indo-Malaya Ecozone, the three major biomes of Rajasthan include deserts and xeric shrublands, tropical and subtropical dry broadleaf forests, and tropical and subtropical moist broadleaf forests. The corresponding ecoregions to the above biomes are, respectively, the Thar Desert and northwestern thorn scrub forests, the Khathiar-Gir dry deciduous forests, and the Upper Gangtic Plains moist deciduous forests. Contrary to popular belief, the well-known Thar or Great Indian Desert occupies only a part of the state. Rajasthan is diagonally divided by the Aravalli mountain ranges into arid and semi-arid regions. The latter have a spectacular variety of highly diversified and unique yet fragile ecosystems comprising lush green fields, marshes, grasslands, rocky patches and hilly terrains, dense forests, the southern plateau, fresh water wetlands, and salt lakes. Apart from the floral richness, there is faunal abundance from fishes to mammals. In this volume, the various flagship and threatened species are described in the 24 chapters penned by top notch wildlife experts and academics. The world famous heronry, tiger reserves, wildlife sanctuaries and some threat-ridden biodiversity rich areas shall certainly draw the attention of readers from around the world.

Wolves are controversial figures worldwide and much effort has focused on how to conserve them while addressing public concerns. With its solitary habits and fruit-eating diet, the endangered maned wolf roams the South American grasslands and swamps, playing a vital part in maintaining biodiversity hotspots. Compared to the grey wolf, little is known about its relationship with local people and the environment and the reasons for its decline, making research about this unique species an urgent concern. Ecology and Conservation of the Maned Wolf: Multidisciplinary Perspectives gathers the work of leading researchers from diverse disciplines and countries, covering up-to-date research on the biology, ecology, and conservation of the maned wolf. It presents innovative insights that can benefit conservation strategies and offers perspectives for the future of the species. The book is divided into three parts. Part I explains the general issues concerning the maned wolf: population viability, the relationship between maned wolves and people, and the management of captive maned wolves. It also reviews current aspects of species biology, including conservation genetics, feeding ecology, social structure and reproduction, and conservation medicine. Part II contains case studies that present knowledge gathered from conservation programs and field research in all countries where the species is currently found-Brazil, Uruguay, Argentina, Bolivia, and Paraguay. Part III offers perspectives from diverse fields of research, exploring the challenges and opportunities connecting maned wolf conservation efforts with those of its habitat and of other endangered species. This includes education and communication tools, the application of human dimensions research to maned wolf conservation, ethnoconservation perspectives, and the ecological and socioeconomic challenges to the conservation of the cerrado habitat.

Many books have now been published in the broad field of environmental toxicology. However, to date, none of have presented the often fascinating stories of the wildlife science, and the steps along the way from discovery of problems caused by environmental pollutants to the regulatory and non-regulatory efforts to address the problems. This book provides case by case examinations of how toxic chemical effects on wildlife have brought about policy and regulatory decisions, and positive changes in environmental conditions. Wild animal stories, whether they are about the disappearance of charismatic top predators, or of grossly deformed embryos or frogs, provide powerful symbols that can and have captured the public's imagination and have resulted in increased awareness by decision makers. It is the intent of this book to present factual and balanced overviews and summaries of the science and the subsequent regulatory processes that followed to effect change (or not). We cover a variety of chemicals and topics beginning with an update of the classic California coastal DDT story of eggshell thinning and avian reproduction to more recent cases, such as the veterinarian pharmaceutical that has brought three species of Asian vultures to the brink of extinction. Researchers, regulators, educators, NGOs and the general public will find valuable insights into the processes and mechanisms involved both in environmental scientific investigation and in efforts to effect positive change.

The population of the Persian leopard (Panthera pardus saxicolor) has drastically declined; this Asian leopard subspecies has disappeared from some parts of its former range. Containing large areas of potential habitats with leopard presence across almost all of its provinces, Iran is known to be the last stronghold for the Persian leopard in the region. This book comprehensively covers research, management and conservation practices of the Persian leopard, including: * The first phase of the Persian Leopard National Action Plan in Iran together with an innovative leopard insurance program and a contingent valuation practice with respect to the wildlife trafficking law enforcement in Iran * Research on a hypothesis about the risk of a major fragmentation and splitting the leopard distribution range in Iran into a northern and a southern parts * An innovative and empirically fitted species- and region-specific approach for assessing the cumulative effect of land use and land cover changes on the leopard persistence * Distribution modeling of leopard potential habitats on a regional basis, accompanied by ground validation techniques * An evaluation to three threshold rules to define the habitat suitability indices * Persian leopard habitats and relative corridors in the trans-boundary areas of the East Azarbaijan province of the northwest of Iran in the Caucasus Ecoregion. The innovative research and conservation approaches presented in this book will be of great interest to those studying the leopard and other large carnivore species. The innovative models presented in this book about cumulative effect of the land use and land cover changes will be beneficial to land use managers, planners and decision makers in selecting wildlife friendly solutions for development programs. The strategic and action planning model as well as the leopard compensation program as an insurance scheme are developed specifically for the local condition and leopard status in Iran.

Ecology and Conservation of Forest Birds is a unique review of current understanding of the relationships between forest birds and their changing environments. Large ecological changes are being driven by forest management, climate change, introduced pests and pathogens, abiotic disturbances, and overbrowsing. Many forest bird species have suffered population declines, with the situation being particularly severe for birds dependent on attributes such as dead wood, old trees and structurally complex forests. With a focus on the non-tropical parts of the Northern Hemisphere, the text addresses the fundamental evolutionary and ecological aspects of forest birds using original data analyses and synthesising reviews. The characteristics of bird assemblages and their habitats in different European forest types are explored, together with the macroecological patterns of bird diversity and conservation issues. The book provides a valuable reference for ecologists, ornithologists, conservation professionals, forest industry employees, and those interested in birds and nature.

Covering a range of metaphors from a diverse field of sciences, from cell and molecular biology to evolution, ecology, and biomedicine, Understanding Metaphors in the Life Sciences explores the positive and negative implications of the widespread use of metaphors in the biological and life sciences. From genetic codes, programs, and blueprints, to cell factories, survival of the fittest, the tree of life, selfish genes, and ecological niches, to genome editing with CRISPR's molecular scissors, metaphors are ubiquitous and vital components of the modern life sciences. But how exactly do metaphors help scientists to understand the objects they study? How can they mislead both scientists and laypeople alike? And what should we all understand about the implications of science's reliance on metaphorical speech and thought for objective knowledge and adequate public policy informed by science? This book will literally help you to better understand the metaphorical dimensions of science.

Contemporary and challenging, this thought-provoking book outlines a number of the key dilemmas in animal welfare for today's, and tomorrow's, world. The issues discussed range from the welfare of hunted animals, to debates around intensive farming versus sustainability, and the effects of climate and environmental change. The book explores the effects of fences on wild animals and human impacts on carrion animals; the impacts of tourism on animal welfare; philosophical questions about speciesism; and the quality and quantity of animal lives. The welfare impacts of human-animal interactions are explored, including human impacts on marine mammals, fish, wildlife, and companion and farm animals. Animal Welfare in a Changing World provides: Concise, opinion-based views on important issues in animal welfare by world experts and key opinion leaders. Pieces based on experience, which balance evidence-based approaches and the welfare impacts of direct engagement through training, campaigning and education. A wide-ranging collection of examples and descriptions of animal welfare topics which outline dilemmas in the real world, that are sometimes challenging, and not always comfortable reading. This is a 'must-read' book for animal and veterinary scientists, ethologists, policy and opinion leaders, NGOs, conservation biologists and anyone who feels passionately about the welfare of animals

Humans have moved organisms around the world for centuries but it is only relatively recently that invasion ecology has grown into a mainstream research field. This book examines both the spread and impact dynamics of invasive species, placing the science of invasion biology on a new, more rigorous, theoretical footing, and proposing a concept of adaptive networks as the foundation for future research. Biological invasions are considered not as simple actions of invaders and reactions of invaded ecosystems, but as co-evolving complex adaptive systems with emergent features of network complexity and invasibility. Invasion Dynamics focuses on the ecology of invasive species and their impacts in recipient social-ecological systems. It discusses not only key advances and challenges within the traditional domain of invasion ecology, but introduces approaches, concepts, and insights from many other disciplines such as complexity science, systems science, and ecology more broadly. It will be of great value to invasion biologists analyzing spread and/or impact dynamics as well as other ecologists interested in spread processes or habitat management.

Begins with in-depth coverage of wildlife behavior concepts as they relate to conservation problems. Topics will focus principally on discussion, critique, and development of behavioral concepts, with particular attention given to published studies on various topics in wildlife behavioral concepts as related to conservation and natural history. He will include an extensive list of references.

Human-wildlife conflict (HWC) has classically been defined as a situation where wildlife impacts humans negatively (physically, economically, or psychologically), and where humans likewise negatively impact wildlife. However, there is growing consensus that the conflict between people about wildlife is as important as the conflict between people and wildlife. HWC not only affects the conservation of one species in a particular geographic area, but also impacts the willingness of an individual, a community, and wider society to support conservation programs in general. This book explores the complexity inherent in these situations, covering the theory, principles, and practical applications of HWC work, making it accessible and usable for conservation practitioners, as well as of interest to researchers more concerned with a theoretical approach to the subject. Through a series of case studies, the book's authors and editors tackle a wide variety of subjects relating to conflict, from the challenges of wicked problems and common pool resources, to the roles that storytelling and religion can play in conflict. Throughout the book, the authors work with a Conservation Conflict Transformation (CCT) approach, adapted from the peacebuilding field to address the reality of conservation today. The authors utilise one of CCT's key analytic components, the Levels of Conflict model, as a tool to provide insight into their case studies. Although the examples discussed are from the world of marine conservation, the lessons they provide are applicable to a wide variety of global conservation issues, including those in the terrestrial realm. Human-Wildlife Conflict will be essential reading for graduate students and established researchers in the field of marine conservation biology. It will also be a valuable reference for a global audience of conservation practitioners, wildlife managers, and other conservation professionals.
