R1,661 Discovery Miles 16 610 Ships in 10 - 15 working days

Imagine a statistics book for bioassays written by a statistician. Next, imagine a statistics book for bioassays written for a layman. Bioassays with Arthropods, Third Edition offers the best of both worlds by translating the terse, precise language of the statistician into language used by the laboratory scientist. The book explains the statistical basis and analysis for each kind of quantal response bioassay in just the right amount of detail. The first two editions were a great reference for designing, conducting, and interpreting bioassays: this completely revised and updated third edition will also train the laboratory scientist to be an expert in estimation of dose response curves. New in the Third Edition: Introduces four new Windows and Apple-based computer programs (PoloJR, OptiDose, PoloMixture and PoloMulti) for the analyses of binary and multiple response analyses, respectively Replaces out-of-date GLIM examples with R program samples Includes a new chapter, Population Toxicology, and takes a systems approach to bioassays Expands the coverage of invasive species and quarantine statistics Building on the foundation set by the much-cited first two editions, the authors clearly delineate applications and ideas that are exceptionally challenging for those not already familiar with their use. They lead you through the methods with such ease and organization, that you suddenly find yourself readily able to apply concepts that you never thought you would understand.

R5,410 Discovery Miles 54 100 Ships in 18 - 22 working days

Insect and disease issues are often specific to the Mediterranean forest systems rather than shared with the temperate forests. In addition to the specific native insects and diseases, the forests are subject to the invasion of exotic species. The forests are also at risk from high degrees of human activity, including changing patterns of forest fires, land management activities, intensive plantation forestry using introduced timber species from other Mediterranean climate zones, and atmospheric deposition. Combined with elements of global climate change that may disproportionately affect Mediterranean climate systems, this creates a number of significant management issues that are unique to the Mediterranean forests. It is our goal that the information contained in this volume will contribute to understanding the unique aspects of Mediterranean forest systems and to protecting these critical resources.

Studying Invertebrates (Paperback): C. Philip Wheater, Penny A. Cook Studying Invertebrates (Paperback)
C. Philip Wheater, Penny A. Cook; Illustrated by Jo Wright
R752 Discovery Miles 7 520 Ships in 10 - 15 working days

Studying invertebrates is a comprehensive guide to designing and carrying out ecological investigations, especially those involving sampling invertebrates. A highly practical guide to fieldwork, statistical testing and interpretation. The book introduces ways of designing and analysing experiments so that complex situations can be described and summarised, comparisons made, and interactions between organisms and their environment examined objectively. This digital reprint replaces ISBN 0-85546-313-9. First published in 2003. Editors' preface The books in this series are designed to encourage readers to undertake their own studies of natural history. Each one describes some relevant techniques, but they have not enough space to cover the substantial body of more generally applicable ideas and approaches that underlies the design and analysis of such field studies. By describing a selection of these general methods, Studying invertebrates aims to support those venturing into ecological fieldwork for the first time. The authors have plenty of experience in helping beginners to plan, carry out and interpret ecological surveys and experiments, and we hope this handbook will serve as a welcome companion and guide, especially for those who lack confidence in their knowledge of statistical and other methods.

R1,974 Discovery Miles 19 740 Ships in 10 - 15 working days

This book will help beekeepers understand the fundamentals of beekeeping science. Written in plain and accessible language by actual researchers, it should be part of every beekeeper's library. The respective chapters not only present raw data; they also explain how to read and understand the most common figures. With topics ranging from honeybee nutrition to strains of Varroa resistant bees, from the effects of pesticide chemicals to understanding diseases, and including a discussion of venom allergies, the book provides essential "knowhow" that beekeepers will benefit from every time they inspect their hives. Further, each chapter ends with the author explaining how beekeepers can (or cannot) directly utilize the information to enhance their beekeeping operation. The text is structured to facilitate ease of use, with each author addressing the same four issues: 1) What are the specific purposes or goals of these experiments? Or more simply: what have these studies taught us? 2) How should a non-scientist read the data generated? 3) What are the key points in relation to practicing beekeepers' goals? 4) How can the data or techniques discussed be applied by beekeepers in their own apiaries? This approach allows readers to look up specific information quickly, understand it and even put it to use without having to read entire chapters. Further, the chapters are highly readable and concise. As such, the book offers a valuable guide and faithful companion for all beekeepers, one they can use day in and day out.

R4,145 Discovery Miles 41 450 Ships in 18 - 22 working days

The chapters in this book were developed from some of the lectures presented at a sym posium at the XX International Congress of Entomology held in Florence, Italy in August 1996. The purpose of the symposium was to discuss the impact of evolving modern agricultural landscapes on the insect species, of both economic and ecological importance, that utilize that habitat. Agricultural policy, to some extent, influences the choices that farmers make and thereby the shape of the agricultural landscape. In order to move toward more sustainable agro ecosystems future policy makers will have to consider the history of land use, consumer demands for both environmentally sound and affordable products, and the conservation of biological diversity. I would hope the information contained in this book will help stimulate discussion about the consequences of policy decisions on our agricultural landscapes and their insect inhabitants. I thank all the speakers from the symposium and in particular those that have been able to contribute chapters to this book. There have been many delays, most due to circumstances beyond anyone's control. I would like to express my appreciation to Gloria Verhey and Patrick Dumont for taking care of the book in these final months.

R6,334 Discovery Miles 63 340 Ships in 18 - 22 working days

Through Green Revolution in late 1960s, India achieved self-sufficiency in food production, but still the country has not achieved self-sufficiency in production of horticultural crops. Most of the growth in food production during the green revolution period is attributed to the use of higher levels of fertilizers and pesticides which are continuing to destroy stable traditional ecosystems. The challenge before the crop protection scientist is to increase yields from the existing land without harming the environment and resource base. This can be achieved by adopting eco-friendly Biointensive Integrated Pest Management (BIPM) strategy.

BIPM incorporates ecological and economic factors into agricultural system design and decision making, and addresses public concerns about environmental quality and food safety. The benefits of implementing BIPM can include reduced chemical input costs, reduced on-farm and off-farm environmental impacts, and more effective and sustainable pest management. An ecology-based IPM has the potential of decreasing inputs of fuel, machinery, and synthetic chemicals-all of which are energy intensive and increasingly costly in terms of financial and environmental impact. Such reductions will benefit the grower and society.

The present book deals with the most recent biointensive integrated approaches for pest management utilizing components such as bioagents predators, parasitoids and pathogens (bacteria, fungi, viruses)], botanicals (biofumigation, oil cakes, FYM, compost, crop residues, green manuring and other organic amendments), arbuscular mycorrhizal fungi, physical methods (hot water treatment of planting material, soil solarization), cultural methods (crop rotation, summer ploughing, fallowing, intercropping, pruning, mulching, spacing, planting date, trap cropping, "etc."), biorational chemicals (pheromones) and resistant cultivars. This book can serve as a useful reference to policy makers, research and extension workers, practicing farmers and students. The material can also be used for teaching post-graduate courses."

Entomologist Justin O. Schmidt is on a mission. Some say it's a brave exploration, others shake their heads in disbelief. His goal? To compare the impacts of stinging insects on humans, mainly using himself as the gauge. In The Sting of the Wild, the colorful Dr. Schmidt takes us on a journey inside the lives of stinging insects, seeing the world through their eyes as well as his own. He explains how and why they attack and reveals the powerful punch they can deliver with a small venom gland and a "sting," the name for the apparatus that delivers the venom. We learn which insects are the worst to encounter and why some are barely worth considering. The Sting of the Wild includes the complete Schmidt Sting Pain Index, published here for the first time. In addition to a numerical ranking of the agony of each of the eighty-three stings he's sampled so far (from below 1 to an excruciatingly painful 4), Schmidt describes them in prose worthy of a professional wine critic: "Looks deceive. Rich and full-bodied in appearance, but flavorless" and "Pure, intense, brilliant pain. Like walking over flaming charcoal with a three-inch nail embedded in your heel." Schmidt explains that, for some insects, stinging is used for hunting: small wasps, for example, can paralyze huge caterpillars and then lay their eggs inside so that their larvae can feast within. Others are used to kill competing insects, even members of their own species. Humans usually experience stings as defensive maneuvers used by insects to protect their nest mates. With colorful descriptions of each venom's sensation and a story that leaves you tingling with awe, The Sting of the Wild's one-of-a-kind style will fire your imagination.
