Insect Biodiversity
Insect Biodiversity: Science and Society brings together leading scientific experts to assess the impact insects have on humankind and the earth’s fragile ecosystems. It examines why insect biodiversity matters and how the rapid evolution of insect species is affecting us all. Insects and related arthropods make up more than 50 percent of the known animal diversity globally, yet a lack of knowledge about insects is hindering the advance of science and society. This book explores the wide variety in type and number of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and also examine the consequences that an increased loss of insect species will have on the world. The book concludes that a better understanding of the biology and ecology of insects is the only way to sustainably manage ecosystems in an ever changing global environment.
Population Parameters
Ecologists and environmental managers rely on mathematical models, both to understand ecological systems and to predict future system behavior. In turn, models rely on appropriate estimates of their parameters. This book brings together a diverse and scattered literature, to provide clear guidance on how to estimate parameters for models of animal populations. It is not a recipe book of statistical procedures. Instead, it concentrates on how to select the best approach to parameter estimation for a particular problem, and how to ensure that the quality estimated is the appropriate one for the specific purpose of the modelling exercise. Commencing with a toolbox of useful generic approaches to parameter estimation, the book deals with methods for estimating parameters for single populations. These parameters include population size, birth and death rates, and the population growth rate. For such parameters, rigorous statistical theory has been developed, and software is readily available. The problem is to select the optimal sampling design and method of analysis. The second part of the book deals with parameters that describe spatial dynamics, and ecological interactions such as competition, predation and parasitism. Here the principle problems are designing appropriate experiments and ensuring that the quantities measured by the experiments are relevant to the ecological models in which they will be used. This book will be essential reading for ecological researchers, postgraduate students and environmental managers who need to address an ecological problem through a population model. It is accessible to anyone with an understanding of basic statistical methods and population ecology. Unique in concentrating on parameter estimation within modelling. Fills a glaring gap in the literature. Not too technical, so suitable for the statistically inept. Methods explained in algebra, but also in worked examples using commonly available computer packages (SAS, GLIM, and some more specialised packages where relvant). Some spreadsheet based examples also included.
Land Management
Mature ecological criticism of agricultural policies is not easy: targets agreed in Biodiversity Action Plans must be achieved within a framework of agricultural and economic policies. Developing a balanced solution is the essence of sustainability. Until recently the hidden costs of high-production systems on biodiversity has been ignored. This booklet identifies some of the hidden costs of unsustainable production, and also considers examples where conservation management has failed. The authors argue that sustainable land management is possible, and that conservation and production interests can be satisfied. They go on to show how a sustainable approach can be applied throughout Europe. The approach adopted is the one that has underpinned the development of the European Union Biodiversity strategy and is becoming a compelling force for change in Europe's decision-making processes. Land managers and planners, ecologists and agriculturalists will, in particular, find this booklet an invaluable resource. However, it will also appeal to those with a more general interest in the issues of land management.
Commerical Fishing
Fishing provides food, income and employment for millions of people. However, fishing has environmental costs that threaten rare species, marine ecosystems and the sustainability of the resource. Based on the research expertise of leading scientists, Commercial Fishing: the Wider Ecological Impacts provides a lively, timely and accessible account of fishing activities and their impacts on marine habitats, biodiversity and species of conservation concern. It covers fishing methods that range from trawling in the Antarctic to fishing with dynamite in the tropics. The authors show how habitats such as the muddy sea beds of the deep sea, kelp forests and coral reefs are affected by fishing and how birds, mammals, turtles and sea snakes both suffer and benefit from fishing activities. They also look to the future, highlighting ways to make fishing gear 'environmentally friendly' and asking whether marine reserves will improve conservation.
The Insects
This established, popular textbook provides a stimulating and comprehensive introduction to the insects, the animals that represent over half of the planet's biological diversity. In this new fourth edition, the authors introduce the key features of insect structure, function, behavior, ecology and classification, placed within the latest ideas on insect evolution. Much of the book is organised around major biological themes – living on the ground, in water, on plants, in colonies, and as predators, parasites/parasitoids and prey. A strong evolutionary theme is maintained throughout. The ever-growing economic importance of insects is emphasized in new boxes on insect pests, and in chapters on medical and veterinary entomology, and pest management. Updated 'taxoboxes' provide concise information on all aspects of each of the 27 major groupings (orders) of insects.

Introduction to Ecotoxicology
Environmental pollution is one of the most serious threats to the future health of our planet. A wide and ever increasing range of chemicals from industry, agriculture, medicine and a host of other sources continue to contribute to the earth's chemical load. Governments have encountered great difficulties responding to the crucial and immediate need for effective management. As a result, the new science of ecotoxicology has developed, which provides a broad conceptual framework for evaluating the effects of chemicals in natural ecosystems. This book is aimed principally at undergraduate students who have completed basic courses in both chemistry and biology. It takes a broad view of ecotoxicology starting with the nature, properties and behaviour of environmental toxicants, and extends to dose/response relationships and effects on organisms, populations, communities and ecosystems. Importantly, it also addresses environmental management areas such as biomarkers, biomonitoring, ecological risk assessment and the ecotoxicology and management of chemicals. The book provides an invaluable overview of the subject for students taking courses in ecotoxicology and environmental pollution, as well as wider degree programmes in biology, ecology, wildlife management, environmental science, environmental impact assessment, toxicology, pollution, chemical engineering, civil engineering, sanitation engineering and related subjects.
Marine Fisheries Ecology
This topical and exciting textbook describes fisheries exploitation, biology, conservation and management, and reflects many recent and important changes in fisheries science. These include growing concerns about the environmental impacts of fisheries, the role of ecological interactions in determining population dynamics, and the incorporation of uncertainty and precautionary principles into management advice. The book draws upon examples from tropical, temperate and polar environments, and provides readers with a broad understanding of the biological, economic and social aspects of fisheries ecology and the interplay between them. As well as covering 'classical' fisheries science, the book focuses on contemporary issues such as industrial fishing, poverty and conflict in fishing communities, marine reserves, the effects of fishing on coral reefs and by-catches of mammals, seabirds and reptiles. The book is primarily written for students of fisheries science and marine ecology, but should also appeal to practicing fisheries scientists and those interested in conservation and the impacts of humans on the marine environment. particularly useful are the modelling chapters which explain the difficult maths involved in a user-friendly manner describes fisheries exploitation, conservation and management in tropical, temperate and polar environments broad coverage of 'clasical' fisheries science emphasis on new approaches to fisheries science and the ecosystem effects of fishing examples based on the latest research and drawn from authors' international experience comprehensively referenced throughout extensively illustrated with photographs and line drawings
