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.
Carnivores include some of the most impressive, dangerous and mysterious animals in the world. Hans Kruuk has spent his life studying them against magnificent backdrops, from the Serengeti savannahs and Kalahari deserts to the Scottish Highlands, from the Galapagos Islands to the Far East. In each location he has used meticulous observation of animal behaviour to understand the ecology and natural history of wild carnivore populations, and ultimately to promote their conservation. This book describes the methods, challenges and rewards of the science of behavioural ecology. However, it essentially concerns the personal, rather than the scientific, side of that work, and above all the field experiences involved. With photographs and line drawings, it brings to life African safaris, the hyena in his bath, flights with vultures, dives with otters, attacks by a badger in Scotland and by feral dogs in Galapagos, gull-eating hedgehogs in Britain and the role of animals in African witchcraft. The author communicates his lifelong fascination with wildlife through these unique experiences and the insights they afforded him. Professor Kruuk is a leading authority on animal behaviour and the author of classic studies of hyaenas, otters and badgers, as well as a biography of his Oxford mentor Niko Tinbergen.
This revised and updated edition of Majerus & Kearns (1989) Ladybirds provides a succinct but comprehensive and accessible overview of the biology of ladybirds and their parasites, focusing on ecology in an evolutionary context. It provides the latest information, coverage of recent additions to the British list including the harlequin ladybird, and makes suggestions for further research, both short and long term, highlighting gaps in knowledge and showing readers how to get involved with recording and studying ladybirds. It includes updated keys for the identification of ladybirds at late-instar larval and adult stages, and techniques for studying ladybirds and their parasites in both laboratory and field. The authors hope that this book will be a valuable resource, not only for students, from school to university and beyond, but also for anyone with an interest in natural history, whether professional or recreational.
The flock of greylag geese established by Konrad Lorenz in Austria in 1973 has become an influential model animal system and one of the few worldwide with complete life-history data spanning several decades. Based on the unique records of nearly 1000 free-living greylag geese, this is a synthesis of more than twenty years of behavioural research. It provides a comprehensive overview of a complex bird society, placing it in an evolutionary framework and drawing on a range of approaches, including behavioural (personality, aggression, pair bonding and clan formation), physiological, cognitive and genetic. With contributions from leading researchers, the chapters provide valuable insight into historic and recent research on the social behaviour of geese. All aspects of goose and bird sociality are discussed in the context of parallels with mammalian social organisation, making this a fascinating resource for anyone interested in integrative approaches to vertebrate social systems.
Oceanic islands are storehouses for unique creatures. Zoologists have long been fascinated by island animals because they break all the rules. Speedy, nervous, little birds repeatedly evolve to become plump, tame and flightless on islands. Equally strange and wonderful plants have evolved on islands. However, plants are very poorly understood relative to animals. Do plants repeatedly evolve similar patterns in dispersal ability, size and defence on islands? This volume answers this question for the first time using a modern quantitative approach. It not only reviews the literature on differences in defence, loss of dispersal, changes in size, alterations to breeding systems and the loss of fire adaptations, but also brings new data into focus to fill gaps in current understanding. By firmly establishing what is currently known about repeated patterns in the evolution of island plants, this book provides a roadmap for future research.
This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.
Large carnivores include iconic species such as bears, wolves and big cats. Their habitats are increasingly being shared with humans, and there is a growing number of examples of human-carnivore coexistence as well as conflict. Next to population dynamics of large carnivores, there are considerable attitude shifts towards these species worldwide with multiple implications. This book argues and demonstrates why human dimensions of relationships to large carnivores are crucial for their successful conservation and management. It provides an overview of theoretical and methodological perspectives, heterogeneity in stakeholder perceptions and behaviour as well as developments in decision making, stakeholder involvement, policy and governance informed by human dimensions of large carnivore conservation and management. The scope is international, with detailed examples and case studies from Europe, North and South America, Central and South Asia, as well as debates of the challenges faced by urbanization, agricultural expansion, national parks and protected areas. The main species covered include bears, wolves, lynx, and leopards. The book provides a novel perspective for advanced students, researchers and professionals in ecology and conservation, wildlife management, human-wildlife interactions, environmental education and environmental social science.
"Living Beings "examines the vital characteristics of social interactions between living beings, including humans, other animals and trees.Many discussions of such relationships highlight the exceptional qualities of the human members of the category, insisting for instance on their religious beliefs or creativity. In contrast, the international case studies in this volume dissect views based on hierarchical oppositions between human and other living beings. Although human practices may sometimes appear to exist in a realm beyond nature, they are nevertheless subject to the pull of natural forces. These forces may be brought into prominence through a consideration of the interactions between human beings and other inhabitants of the natural world.The interplay in this book between social anthropologists, philosophers and artists cuts across species divisions to examine the experiential dimensions of interspecies engagements. In ethnographically and/or historically contextualized chapters, contributors examine the juxtaposition of human and other living beings in the light of themes such as wildlife safaris, violence, difference, mimicry, simulation, spiritual renewal, dress and language.
How do plants, animals, and humans manage to survive and adapt to the urban environment? This book provides a comprehensive coverage of biological matters related to urban environments presenting both the conceptual and theoretical underpinnings, and practical examples required to understand and address the challenges presented by this novel environment. The Biology of Urban Environments focusses on urban denizens: species (both domesticated and non-domesticated) that live for all or part of their life cycle in towns and cities. The biology of household plants and companion animals is discussed alongside that of species that have become feral or have not been domesticated. Temporal and spatial distribution patterns are set out and generalizations are made while exceptions are also discussed. The various strategies used and the genotypic, phenotypic, and behavioural adaptions of plants and animals in the face of the challenges presented by urban environments are explained. The final two chapters contain a discussion of the impacts of urban environments on human biology and suggestions on how this understanding might be used to address the increasing human health burden associated with illnesses that are characteristic of urbanites in the early twenty-first century.
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.
When a predator attacks, prey are faced with a series of 'if', 'when' and 'how' escape decisions - these critical questions are the foci of this book. Cooper and Blumstein bring together a balance of theory and empirical research to summarise over fifty years of scattered research and benchmark current thinking in the rapidly expanding literature on the behavioural ecology of escaping. The book consolidates current and new behaviour models with taxonomically divided empirical chapters that demonstrate the application of escape theory to different groups. The chapters integrate behaviour with physiology, genetics and evolution to lead the reader through the complex decisions faced by prey during a predator attack, examining how these decisions interact with life history and individual variation. The chapter on best practice field methodology and the ideas for future research presented throughout, ensure this volume is practical as well as informative.
Birds are renowned for their exceptional vision and the way that this enables them to survive and navigate the world in such a unique way. However, it is now recognised that avian behaviour is guided by information drawn from many different senses which are then used in integrated and complementary ways to answer the many different sensory challenges posed by specific environments and particular tasks. Understanding how sensory information is used by birds has important applications in conservation, such as providing vital insights into why birds are prone to collisions with structures like power lines and wind turbines, and why so many diving birds become entrapped in nets. A sensory ecology approach suggests how these problems can be mitigated. The Sensory Ecology of Birds ranges widely across species, environments, and behaviours to present a synthesis that challenges previous assumptions about the information that controls the behaviour of birds. A bird may use a wide range and combination of sensory information that comes from sight, hearing, smell, mechanoreception, taste, and magnetoreception. It may also include specific refinements of senses, such as echolocation and remote touch from the bill. The book recognises that there are many complex and subtle trade-offs and complementarities of information between different types of sensory information. This accessible text will be of interest to a wide ornithological readership, from undergraduates to researchers as well as a broader audience of behavioural ecologists and evolutionary biologists.
Ecology studies biodiversity in its variety and complexity. It describes how species distribute and perform in response to environmental changes. Ecological processes and structures are highly complex and adaptive. In order to quantify emerging ecological patterns and investigate their hidden mechanisms, we need to rely on the simplicity of mathematical language. Ecological patterns are emerging structures observed in populations, communities and ecosystems. Elucidating drivers behind ecological patterns can greatly improve our knowledge of how ecosystems assemble, function and respond to change and perturbation. Mathematical ecology has, thus, become an important interdisciplinary research field that can provide answers to complex global issues, such as climate change and biological invasions. The aim of this book is to (i) introduce key concepts in ecology and evolution, (ii) explain classic and recent important mathematical models for investigating ecological and evolutionary dynamics, and (iii) provide real examples in ecology/biology/environmental sciences that have used these models to address relevant issues. Readers are exposed to the key concepts, frameworks, and terminology in the studies of ecology and evolution, which will enable them to ask the correct and relevant research questions, and frame the questions using appropriate mathematical models.
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? M² 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. M² 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 M². M² 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.
Assembles a collection of experts to provide a current account of different approaches (e.g., traditional, comparative and experimental) being applied to study mobility. Moreover, the book aims to stimulate new theoretical perspectives that adopt a holistic view of the interaction among intrinsic (i.e. skeletal) and extrinsic (i.e. environmental) factors that influence differential expression of mobility. Since the environment undoubtedly impacts mobility of a wide variety of animals, insights into human mobility, as a concept, can be improved by extending approaches to investigating comparable environmental influences on mobility in animals in general. The book teases apart environmental effects that transcend typical categories (e.g., coastal versus inland, mountainous versus level, arboreal versus terrestrial). Such an approach, when coupled with a new emphasis on mobility as types of activities rather than activity levels, offers a fresh, insightful perspective on mobility and how it might affect the musculoskeletal system.
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
This book develops and tests an ecological and evolutionary theory of the causes of human values—the core beliefs that guide people’s cognition and behavior—and their variation across time and space around the world. We call this theory the parasite-stress theory of values or the parasite-stress theory of sociality. The evidence we present in our book indicates that both a wide span of human affairs and major aspects of human cultural diversity can be understood in light of variable parasite (infectious disease) stress and the range of value systems evoked by variable parasite stress. The same evidence supports the hypothesis that people have psychological adaptations that function to adopt values dependent upon local infectious-disease adversity. The authors have identified key variables, variation in infectious disease adversity and in the core values it evokes, for understanding these topics and in novel and encompassing ways. Although the human species is the focus in the book, evidence presented in the book shows that the parasite-stress theory of sociality informs other topics in ecology and evolutionary biology such as variable family organization and speciation processes and biological diversity in general in non-human animals.
Howler monkeys (genus Alouatta) comprise 12 species of leaf-eating New World monkeys that range from southern Mexico through northern Argentina. This genus is the most widespread of any New World primate and can be found to inhabit a range of forest types from undisturbed rainforest to severely anthropogenically-impacted forest fragments. Although there have been many studies on individual species of howler monkeys, this book is the first comprehensive volume that places information on howler behavior and biology within a theoretical framework of ecological and social adaptability. This is the first of two companion volumes devoted to the genus Alouatta. This volume: * Provides new and original empirical and theoretical research on howler monkeys * Presents evolutionary and adaptive explanations for the ecological success of howler monkeys * Examines howler behavior and ecology within a comparative framework These goals are achieved in a collection of chapters written by a distinguished group of scientists on the evolutionary history, paleontology, taxonomy, genetics, morphology, physiology, and anatomy of howlers. The volume also contains chapters on howlers as vectors of infectious diseases, ethnoprimatology, and conservation.
The work summarizes the current knowledge regarding the controlled reproduction of an emerging aquaculture species, the Eurasian perch (Perca fluviatilis). In great detail it describes and explains the principal of most of the controlled reproductive protocol leading to obtain high quality larvae. The book is primarily intended to be used as a hatchery manual by practicing aquaculturists and laboratory technicians working with this species. On the other hand, it also summarizes the scientific background of the methods applied, therefore, it can serve as a reference for the state-of-the-art in the controlled reproduction of Eurasian perch and other freshwater percid species.
Howler monkeys (genus Alouatta) comprise twelve species of leaf-eating New World monkeys that range from southern Mexico through northern Argentina. This genus is the most widespread of any New World primate taxa, and can be found to inhabit a range of forest types from undisturbed rainforest to severely anthropogenically impacted forest fragments. Although there have been many studies on individual species of howler monkeys, this book is the first comprehensive volume to place information on howler behavior and biology within a theoretical framework of ecological and social adaptability. This is the second of two volumes devoted to the genus Alouatta. This volume: * Examines behavioral and physiological mechanisms that enable howler monkeys to exploit highly disturbed and fragmented habitats * Presents models of howler monkey diet, social organization, and mating systems that can also inform researchers studying Old World colobines, apes, and other tropical mammals These goals are achieved in a collection of chapters written by a distinguished group of scientists on the feeding ecology, behavior, mating strategies, and management and conservation of howlers. This book also contains chapters on the howler microbiome, the concept of behavioral variability, sexual selection, and the role of primates in forest regeneration.
The small, terrestrial eastern red-backed salamander is abundant on many forest floors of northeastern North America. Dr. Robert Jaeger and many of his graduate students spent over 50 years studying this species in New York and Virginia, using ecological techniques in forests and behavioral experiments in laboratory chambers in an attempt to understand how this species interacts with other species in the forest and the components of its intra- and intersexual social behaviors. The competitive and social behaviors of this species are unusually complex for an amphibian. This species is highly aggressive towards other similar-size species where they cohabit in forests, often leading to very little geographic overlap between the species. The authors examine the fascinating behavioral traits of this species including social monogamy, mutual mate guarding, sexual coercion, inter-species communication, and conflict resolution.
This book sheds new light on the causes and consequences of elephant migration in the Panchet Forest Division of Bankura District in West Bengal, India- an area characterized by fragmented forested landscape modified by agriculture and settlement expansion. Anthropogenic activities result in the decline in quality and coverage of forests, loss of biodiversity and removal of forest corridors which ultimately restrict or modify the movement of elephants causing a forceful change of their habitats. A major objective of this monograph is to identify the characteristics of man-elephant conflicts in terms of land use change, cropping patterns, ecological characteristics of the fragmented dry deciduous forest, trends and patterns of elephant migration, and livelihood patterns of the inhabitants in the affected areas. Readers will discover insights into changes in the behavioral pattern of elephants and local people in the conflict ridden zones, and how this influences food selection. Through this book we also learn about rational management strategies that can be employed on the local and national level to mitigate human-elephant conflicts. Ecologists, landscape conservation planners and environmental managers engaged in the conservation of large vertebrates in fragmenting and human-dominated landscapes will find this book valuable.
The mighty and majestic European bison is the relictual embodiment of the wildness of prehistoric Europe. Tragically, the millennia since that time have seen so many species driven to extinction by human impacts, and the European bison has only narrowly avoided the same fate. Today, the species represents the symbolic sentinel of successful conservation actions in a world in which such achievements remain few and far between. From an early stage in the restitution of the European bison, husband-and-wife team Malgorzata Krasinska and Zbigniew A. Krasinski have been participating in relevant management initiatives and researching all facets of the bison, from its morphology and diet, to its movements, social life and reproduction, and the conservation management actions that have been taken to save it. Now they have summarised this wealth of knowledge on the species, giving rise to a publication ideal for students, professional biologists and conservationists, but also for all nature enthusiasts. This new edition of the monograph offers extensively updated content taking into account research carried out on the European bison in the last few years. Also featured, a new chapter devoted to knowledge of the genetics of the species drawn up by Malgorzata Tokarska of the Bialowieza-based Mammal Research Institute PAS.
Microbial ecology is the study of interactions among microbes in natural environments and their roles in biogeochemical cycles, food web dynamics, and the evolution of life. Microbes are the most numerous organisms in the biosphere and mediate many critical reactions in elemental cycles and biogeochemical reactions. Because they are essential players in the carbon cycle and related processes, microbial ecology is a vital science for understanding the role of the biosphere in global warming and the response of natural ecosystems to climate change. This second edition has been fully revised, restructured, and updated while remaining concise and accessible. It discusses the major processes carried out by viruses, bacteria, fungi, protozoa and other protists - the microbes - in freshwater, marine, and terrestrial ecosystems. The focus is on biogeochemical processes, starting with primary production and the initial fixation of carbon into cellular biomass, before exploring how that carbon is degraded in both oxygen-rich (oxic) and oxygen-deficient (anoxic) environments. These processes are in turn affected by ecological interactions, including competition for limiting nutrients, viral lysis, and predation by various protists in soils and aquatic habitats. The book neatly connects processes occurring at the micron scale to events happening at the global scale, including the carbon cycle and its connection to climate change issues. A final chapter is devoted to symbiosis and other relationships between microbes and larger organisms. Microbes have huge impacts not only on biogeochemical cycles, but also on the ecology and evolution of more complex forms of life, including humans.
Current dominant thinking and practice in the private and public sectors asserts that peoples' development needs are in conflict with, or mutually exclusive to, the need to conserve the biosphere on which we depend. Consequently, we are asked to either diminish development in the name of conservation or diminish conservation in the name of development. Efforts to identify complementary objectives, or mutually acceptable trade-offs and compromises indicate, however, that this does not always have to be the case. This first volume in the State of the Apes series draws attention to the evolving context within which great ape and gibbon habitats are increasingly interfacing with extractive industries. Intended for a broad range of policy makers, industry experts, decision makers, academics, researchers and NGOs, these publications aim to influence debate, practice and policy, seeking to reconcile ape conservation and welfare, and economic and social development, through objective and rigorous analysis. |
