This book addresses microinsects, their structure and their differences from larger relatives. Moreover, it discusses structural changes that accompany extreme diminution in living organisms, evolutionary inventions that help insects to live in the microworld, and factors that limit the size of animals. It also takes a careful look at the potential benefits of the study of microinsects for solving biotechnological and fundamental scientific problems. Miniaturization is not only a trend in technology: it is also one of the trends in the evolution of life. Many of the problems modern engineers are still struggling with were solved by nature millions of years ago. The world of microscopic organisms, invisible to the naked eye, is all around us. Microinsects - the extremely diverse range of miniature insects less than a millimeter long - are one of the most intriguing components of this microworld. Having evolved to the size of unicellular organisms, the smallest insects managed not only to preserve their structural complexity, but also to evolve some novel features not found in larger insects.
Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.
'A bold, ambitious and truly wonderful history of the world' Peter Wohlleben, author of The Hidden Life of Trees 'A fascinating story and a crucial revision of the momentous importance of tropical forests to human history' Lewis Dartnell, author of Origins _________________________ Jungle tells the remarkable story of the world's tropical forests, from the arrival of the first plants millions of years ago to the role of tropical forests in the evolution of the world's atmosphere, the dinosaurs, the first mammals and even our own species and ancestors. Highlighting provocative new evidence garnered from cutting-edge research, Dr Roberts shows, for example, that our view of humans as 'savannah specialists' is wildly wrong, and that the 'Anthropocene' began not with the Industrial Revolution, but potentially as early as 6,000 years ago in the tropics. We see that the relationship between humankind and 'jungles' is deep-rooted, that we are all connected to their destruction, and that we must all act to save them. Urgent, clear-sighted and original, Jungle challenges the way we think about the world - and ourselves. _________________________ 'Welcome to the "Jungle" - a breathtaking book' Mark Maslin, author of How to Save Our Planet 'Timely, readable and highly relevant' Steve Brusatte, author of The Rise and Fall of the Dinosaurs 'Its revelations and stories will stir, rearrange and populate your mind for years to come' Paul Hawken, editor of Drawdown 'Brilliant ... it delivers a timely warning about our abuse of the environment' David Abulafia, author of The Great Sea 'Finally, a book on rainforests that does justice to their majesty and importance' Simon Lewis, co-author of The Human Planet
This unique book synthesizes the ongoing long-term community
ecology studies of fish, amphibians, reptiles, birds, and mammals.
The studies have been conducted from deserts to rainforests as well
as in terrestrial, freshwater, and marine habitats and provide
valuable insight that can be obtained only through persistent,
diligent, and year-after-year investigation.
Globally, more and more species are at risk of extinction as the environment and climate change. Many of these species require long-term management to persist - they are conservation-reliant. The magnitude of this challenge requires a rethinking of how conservation priorities are determined and a broader societal commitment to conservation. Choices need to be made about which species will be conserved, for how long, and by whom. This volume uses case studies and essays by conservation practitioners from throughout the world to explore what conservation reliance is and what it means for endangered-species management. Chapters consider threats to species and how they are addressed, legal frameworks for protecting endangered species, societal contexts and conflicts over conservation goals, and how including conservation reliance can strengthen methods for prioritizing species for conservation. The book concludes by discussing how shepherding nature requires an evaluation of societal values and ethics.
Invasive species are among the greatest challenges to environmental sustainability and agricultural productivity in the world. One of the most promising approaches to managing invasive species is voluntary citizen stewardship. However, in order for control measures to be effective, private citizens often need to make sustained and sometimes burdensome commitments. Community-Based Control of Invasive Species is based on five years of research by leading scholars in natural resource and human behavioural sciences, which involved government and citizen groups in Australia and the United States. It examines questions including, 'how can citizens be engaged in voluntarily managing invasive species?', 'what communication strategies will ensure good motivation and coordination?' and 'how can governing bodies support citizens in their efforts?'. With chapters on institutional frameworks, changing governance, systems thinking, organisational learning, engagement, communication and behavioural change, this book will be a valuable reference for researchers and practitioners involved in natural resources management.
A rapidly growing interdisciplinary field, disease ecology merges key ideas from ecology, medicine, genetics, immunology, and epidemiology to study how hosts and pathogens interact in populations, communities, and entire ecosystems. Bringing together contributions from leading international experts on the ecology of diseases among invertebrate species, this book provides a comprehensive assessment of the current state of the field. Beginning with an introductory overview of general principles and methodologies, the book continues with in-depth discussions of a range of critical issues concerning invertebrate disease epidemiology, molecular biology, vectors, and pathogens. Topics covered in detail include: Methods for studying the ecology of invertebrate diseases and pathogens Invertebrate pathogen ecology and the ecology of pathogen groups Applied ecology of invertebrate pathogens Leveraging the ecology of invertebrate pathogens in microbial control Prevention and management of infectious diseases of aquatic invertebrates Ecology of Invertebrate Diseases is a necessary and long overdue addition to the world literature on this vitally important subject. This volume belongs on the reference shelves of all those involved in the environmental sciences, genetics, microbiology, marine biology, immunology, epidemiology, fisheries and wildlife science, and related disciplines.
Infrastructure development in Africa and Asia is expanding at breakneck speed, largely in biodiversity-rich developing nations. The trend reflects governments' efforts to promote economic growth in response to increasing populations, rising consumption rates and persistent inequalities. Large-scale infrastructure development is regularly touted as a way to meet the growing demand for energy, transport and food - and as a key to poverty alleviation. In practice, however, road networks, hydropower dams and 'development corridors' tend to have adverse effects on local populations, natural habitats and biodiversity. Such projects typically weaken the capacity of ecosystems to maintain ecological functions on which wildlife and human communities depend, particularly in the face of climate change. This title is also available as Open Access via Cambridge Core.
Along with reproduction, balancing energy expenditure with the limits of resource acquisition is essential for both a species and a population to survive. But energy is a limited resource, as we know well, so birds and mammals - the most energy-intensive fauna on the planet - must reduce energy expenditures to maintain this balance, some taking small steps, and others extreme measures. Here Brian K. McNab draws on his over sixty years in the field to provide a comprehensive account of the energetics of birds and mammals, one fully integrated with their natural history. McNab begins with an overview of thermal rates - much of our own energy is spent maintaining our 98.6[degrees]F temperature - and explains how the basal rate of metabolism drives energy use, especially in extreme environments. He then explores those variables that interact with the basal rate of metabolism, like body size and scale and environment, highlighting their influence on behavior, distribution, and even reproductive output. Successive chapters take up energy and population dynamics and evolution. A critical central theme that runs through the book is how the energetic needs of birds and mammals come up against rapid environmental change and how this is hastening the pace of extinction.
The monograph focuses on the European freshwater pearl mussel Margaritifera margaritifera, which is an endangered bivalve species. Most of its populations in the Russian section of the Baltic Sea basin had never been studied, although they were known in the past to the pearl fishers. "Rediscovery" included search for the previously unknown populations, revealing the facts of population extinctions, analysis of negative impacts, elaboration of conservation measures, and revealing of regularities in distribution. Patterns of land use and river management were analyzed. The procedure of "rediscovery" was applied for other animal species of Northwest Russia, which are threatened on a global scale - thick-shelled mussel, Unio crassus; curlew Numenius arquata; black-tailed godwit, Limosa limosa; Northern Lapwing, Vanellus vanellus; European mink, Mustela lutreola; pond bat, Myotis dasycneme; Atlantic sturgeon, Acipenser sturio; and broad-clawed crayfish, Astacus astacus. The methods and principles of conservation studies were discussed. The obtained data were analyzed with respect to current global change of biosphere. The book will appeal to specialists dealing with conservation studies and activities such as red lists, river protection, and conservation of endangered species. Moreover, a part of the book represents an interest for biogerontology as it presents discredit of the popular concept on "negligible senescence." The data on distribution of some animals in Russia will be interesting in terms of zoology and biogeography, as they are not yet sufficiently represented in the international editions. The book can be used as supplemental reading for courses in biological invasions, ecology and conservation, and biodiversity. The work also contains chapters on global processes (deforestation, desertification, river degradation) and can therefore also be used for general courses in environmental sciences.
Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be used when future conditions are unpredictable due to feedbacks from the behavior of other individuals. This book provides a comprehensive introduction to state- and prediction-based theory, or SPT, a powerful new approach to modeling trade-off behaviors in contexts such as individual-based population models where feedbacks and variability make optimization impossible. Modeling Populations of Adaptive Individuals features a wealth of examples that range from highly simplified behavior models to complex population models in which individuals make adaptive trade-off decisions about habitat and activity selection in highly heterogeneous environments. Steven Railsback and Bret Harvey explain how SPT builds on key concepts from the state-based dynamic modeling theory of behavioral ecology, and how it combines explicit predictions of future conditions with approximations of a fitness measure to represent how individuals make good-not optimal-decisions that they revise as conditions change. The resulting models are realistic, testable, adaptable, and invaluable for answering fundamental questions in ecology and forecasting ecological outcomes of real-world scenarios.
Network thinking and network analysis are rapidly expanding features of ecological research. Network analysis of ecological systems include representations and modelling of the interactions in an ecosystem, in which species or factors are joined by pairwise connections. This book provides an overview of ecological network analysis including generating processes, the relationship between structure and dynamic function, and statistics and models for these networks. Starting with a general introduction to the composition of networks and their characteristics, it includes details on such topics as measures of network complexity, applications of spectral graph theory, how best to include indirect species interactions, and multilayer, multiplex and multilevel networks. Graduate students and researchers who want to develop and understand ecological networks in their research will find this volume inspiring and helpful. Detailed guidance to those already working in network ecology but looking for advice is also included.
Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.
In Butterfly Biology Systems Roger Dennis explores key topics and contentious issues in butterfly biology, specifically those in life history and behaviour. Uniquely, using a systems approach, the book focuses on the degree of integration and feedback between components and elements affecting each issue, as well as the links between different issues. The book comprises four sections. The first two sections introduce the reader to principles and approaches for investigating complex relationships, and provide a platform of knowledge on butterfly biology. The final two sections deal in turn with life history and behaviour, covering key issues affecting different stages of development from eggs to adults. The book is extensively illustrated with original diagrams and models, all of which have detailed legends, produced to enhance a broader understanding, and to provide templates for future research. It includes a detailed bibliography and glossary providing an essential gateway to the extensive literature on butterfly biology. Butterfly Biology Systems is essential reading for graduate students and researchers in insect ecology, evolution, behaviour and conservation. It will also be of great value to anyone interested in butterflies. Introduces a systems approach to butterfly biology Includes succinct reviews of the key interrelationships in butterfly life history and behaviour Illustrates more than 100 models to advance research into butterfly biology systems
This book provides applied biologists and ecologists with the mathematical tools they need to understand the ever increasingly mathematical and complex area of population ecology.
Until recently, the production of fruits by plants, their consumption by animals (frugivory) and the relevance of these to seed dispersal have attracted less attention than topics such as pollination biology. However, since the 1970s they have started to gain more prominence and now give rise to more research funding, seminal papers and international symposiums. This book contains chapters adapted from the Third International Symposium-Workshop on Frugivores and Seed Dispersal held in August 2000, in Rio Quente, Brazil.
This successful text examines the ecological processes that determine the size and structure of a population, and demonstrates that there are many fundamental principles that apply to populations of both animals and plants. The authors have sought to involve the text in areas where particular progress has been made and consolidated. The third edition therefore addresses the problem of the detection of chaos, buried sea-banks and herbivorey implants and looks more closely at the role of spatial scale in two-species interactions. It also introduces a major new section on the concept of the meta-population. The book is designed to be readily understood by undergraduates with little or no previous knowledge of the subject, and also to stimulate wider debate and discussion.
This book is an essential reference source covering the chemical elements that are nutrients for plants or grazing animals. It deals with the concentrations and transformations of these elements in soils, grassland plants, and ruminant animals, particularly cattle and sheep. For each element, the following data are given: forms occurring in soil, factors that affect availability and concentration, uptake and distribution in grassland plants, role in animal nutrition, amounts and forms excreted by grazing animals, and concentrations needed by ruminant animals.
In this edited work, international experts in fisheries management
and ecology review and appraise the status of river fisheries,
assessment methodology, constraints on development, issues and
options regarding management and associated problems in both
temperate and tropical countries. Recommendations are made to
improve management and an attempt is made to provide guidelines for
formulating policy, for planning methodology and for evaluating
future activities.

The understanding and management of land resources used by grazing animals are of major importance to ecologists and agricultural and environmental scientists. This book fills a major gap in the market by synthesising a range of perspectives on grazing systems, drawn from plant science, animal science and ecology. It outlines the principles of herbage growth and competition, of animal nutrition and grazing behaviour, and of the interactions of plant and animal factors that are central to an understanding of grazing systems. Chapters on the management of grazing systems cover both intensive and extensive systems (including rangelands) from all major agroecological zones of the world. The book is written by leading authorities from the USA, UK, Australia, New Zealand, South Africa, Israel and France. It represents a major contribution to the literature for advanced students and research workers concerned with plant science (especially grasslands), animal science (especially ruminants), and natural and agricultural ecosystems.
From the world-famous expert on chimpanzees - the powerfully compelling sequel to the international bestseller IN THE SHADOW OF MAN: 'An instant animal classic' Time Equipped with little more than a notebook, binoculars, and her fascination with wildlife, Jane braved a realm of unknowns to give the world a remarkable window into humankind's closest living relatives. On the shores of Lake Tanganyika, Gombe is a community where the principal residents are chimpanzees. Through Goodall's eyes we watch as the younger chimpanzees vie for power, and how the leaders must deal with this challenge. We learn how one mother successfully rears her children, whilst another appears to doom her offspring to failure. All life is here - glorious births and heart-breaking deaths, moments of brutality, alongside the most tender displays of affection. In THROUGH A WINDOW, as Jane Goodall reveals the story of this intimately intertwined community, we are shown the parallels with human emotions laid bare. Indeed, in the mirror of chimpanzee life, we see ourselves reflected.
The basic biology of owls is poorly understood compared to that of other bird species. The Little Owl, Athene noctua, is one of the best models for biological and conservation research. Though widespread across Europe, Asia and North Africa, populations of the Little Owl are now in decline, making studies of its behavior and ecology all the more important. This extensively revised and updated second edition features substantial new long-term data on population dynamics, behavioral observations and breeding biology of the Little Owl. The authors discuss its wide-ranging ecology, genetics, subspecies, and population status by country. In addition, they outline a research strategy and monitoring program. Exceptional illustrations of all fourteen subspecies cover embryonic and chick development, feather growth and moult, including high-quality drawings presenting concrete management suggestions. Whilst being an invaluable resource for academic researchers, its accessible and straightforward style will also appeal to amateur ornithologists and enthusiasts.
The Butterflies of Britain & Ireland provides comprehensive coverage of all our resident and migratory butterflies, including the latest information on newly discovered species such as Cryptic Wood White and the Geranium Bronze. When first published in 1991 it won the Natural World Book of the Year Award and won plaudits from all quarters. Fully revised, considerably expanded and reset in 2010, it was judged that year's Guardian Nature Book of the Year. Now revised again to reflect the latest research findings, and with up-to-date distribution maps, this remarkable book is THE guide to the appearance, behaviour, life cycle and ecology of the butterflies of Britain and Ireland.
Shortlisted for the 2018 TWS Wildlife Publication Awards in the edited book category Decomposition and recycling of vertebrate remains have been understudied, hampered largely due to these processes being aesthetically challenging (e.g., smell and sight). Technological innovations have provided the means to explore new and historically understood natural systems to give us a plethora of new information. Carrion Ecology, Evolution, and Their Applications covers a broad spectrum of topics including the molecular mechanistic foundations that provide the basis for intra- and interspecific interactions related to population biology, community ecology, and how this manifests into habitat- and ecosystem-level importance. The book connects the science of carrion decomposition from genes to ecosystems in multidisciplinary synthesis of the science. This book brings together a team of global experts involved with measuring and understanding the process and effects of carrion ecology in nature, with special application in such applied fields as forensic entomology, habitat management, animal production (e.g., livestock and aquaculture), and human and environmental health. It fills a large literature gap in ecology, providing a synthesis and future directions important for studies of carrion decomposition that improve the general understanding of decomposition in ecosystems. The book fuses multiple disciplines into a single message explaining the importance of vertebrate carrion ecology in nature. Illustrates Carrion Decomposition in a 16-Page Color Insert with 40 Photos The authors illustrate how the study of carrion transcends the globe and expands systems of inquiry, broadening awareness of this important ecosystem process. Whether you are a student, academic, or professional, you will find this book insightful for the fields of molecular ecology, microbiology, entomology, forensics, population biology, community and ecosystem ecology, and human and environmental health. |
