Perspectives on the Marine Animal Forests of the World

by Sergio Rossi Lorenzo Bramanti

Marine Animal Forests (MAFs) are spread all over the world. Composed by suspension feeding organisms (e.g. corals, gorgonians, sponges, bryozoans, bivalves, etc.), MAFs constitute a vast number of marine ecosystems such as coral reefs, cold water corals, sponge grounds, bivalve beds, etc. The surface covered by these systems is prominent (at the scale of the oceans of the planet), though poorly known. In a previous book (Marine Animal Forests, the ecology of benthic biodiversity hotspots), several aspects of the MAFs were described and discussed, building the basis for a holistic approach with the aim of putting these shallow and deep sea ecosystems under a common umbrella. The main target of the present book is to identify and address important topics which were not covered in the previous three volumes. Bryozoans or Polychaeta, for example, are treated in this volume, as well as hydrothermal vents ecosystems and submarine caves, the chemical ecology in MAFs or the nursery effect on these ecosystems. The vastity of the MAF concept opens new insights in the biology, physiology, biodiversity of the organisms structuring these highly biodiverse ecosystems and on the dangers threatening them (such as microplastics or the role of invasive species as an impact of their trophic ecology or distribution). In a fast changing world, in which the complexity of MAFs is at risk, we propose an in-depth analysis of many aspects that may be inspirational for future research lines in marine biology and ecology.

Pest Management and Phytosanitary Trade Barriers

by Neil W. Heather Guy J. Hallman

A significant amount of the world's economy is based upon the international trade of agricultural produce. For the producing countries, a growing concern is the potential economic and ecological damage that invasive species could cause. While threats can be decreased through the regulation of items potentially carrying invasive species, the effect of such restrictions on international trade also needs to be considered. A balance must therefore be met that permits the transfer of produce while filtering out unwanted pests. Drawing on the author's extensive experience, the social and financial implications of phytosanitary trade barriers are reviewed. This book offers valuable and comprehensive coverage of pest related barriers and strategies for their implementation.

Pest Management in Cotton: A Global Perspective

by Zeeshan Ahmed

This book presents a global overview of the background to, and the current state of, crop protection and pest management in cotton crops. Cotton is one of the most economically important crops in the world and has been grown for centuries but maintaining high yields of good quality requires sophisticated approaches to pest management. The introduction and use of pesticides over the decades significantly increased cotton yields but lead to many adverse environmental impacts. Over time, new and alternative insecticides were developed but overuse has enabled pests to develop significant resistance. The development of genetically modified cotton varieties with toxins derived from Bacillus thuringiensis enabled much improved control of lepidopteran larvae, including bollworms, but as the toxins had no effect on sucking pests, farmers had no choice but to continue using insecticides. Also, some of the new cotton varieties developed in recent times have not adapted to different climatic conditions and the quality of cotton fibre declined as a result. This book shows the need for more research to select cotton varieties with high quality fibres suitable for different cotton growing areas and to develop integrated pest management strategies to minimise the use of pesticides. It also demonstrates the need for an inter-disciplinary approach bringing together plant breeders, entomologists, plant pathologists, agronomists and agricultural engineers to achieve high yields of high quality cotton. In the future, farmers will need to adopt new technology to determine when and how pesticides are used in conjunction with cultural and biological control strategies. · Emphasises the importance of research on growing cotton in a world experiencing climate change · Demonstrates how crucial crop protection is in achieving high yields of high quality cotton · Shows how new technology will bring major changes in how cotton is grown in the future

One way to increase food security is to decrease the amount of yield lost to pests. The Pesticide Encyclopedia provides a comprehensive overview of the fight against pests, covering chemical pesticides, biocontrol agents and biopesticides. It also covers interrelated topics such as pesticide toxicity, legislation and regulation, handling, storage and safety aspects, IPM techniques, resistance management, interaction of pesticides with soil and the environment. An important reference for policy makers, advisers and students and researchers of crop science, this book also includes useful notes on commonly known plant diseases and pests.

Pesticide Policy, Production Risk, and Producer Welfare: An Econometric Approach to Applied Welfare Economics (Routledge Revivals)

by John M. Antle

The use of pesticides to control agricultural pests both benefits farm production and imposes health and environmental costs on producers and society. This title, first published in 1988, includes an application of the author’s methodology to tomato production, in which Antle illuminates the roles that alternative methods of pest management play in producer welfare. He also develops a more general empirical framework for studying producer welfare under uncertainty – a framework in which production risk, sequential decision making, and attitudes toward risk are integrated. This title will be of interest to students of environmental studies.

Pesticides

by Graham Matthews

Crop protection continues to be an important component of modern farming to maintain food production to feed an expanding human population, but considerable changes have occurred in the regulation of pesticides in Europe in the last decade. The aim has been to reduce their impact on people and the environment. This has resulted in a major reduction in the number of chemicals approved for application on crops. In other parts of the world, a continuing expansion in the growing of genetically modified crops has also changed the pattern of pesticide use. In this second edition, Graham Matthews, updates how pesticides are registered and applied and the techniques used to mitigate their effects in the environment. Information on operator safety, protection of workers in crops treated with pesticides and spray drift affecting those who live in farming areas is also discussed. By bringing together the most recent research on pesticides in a single volume, this book provides a vital up to date resource for agricultural scientists, agronomists, plant scientists, plant pathologists, entomologists, environmental scientists, public health personnel, toxicologists and others working in the agrochemical industry and governments. It should assist development of improvements in harmonising regulation of pesticides in countries with limited resources for registration of pesticides.

Pests: How Humans Create Animal Villains

by Bethany Brookshire

An engrossing and revealing study of why we deem certain animals “pests” and others not—from cats to rats, elephants to pigeons—and what this tells us about our own perceptions, beliefs, and actions, as well as our place in the natural worldA squirrel in the garden. A rat in the wall. A pigeon on the street. Humans have spent so much of our history drawing a hard line between human spaces and wild places. When animals pop up where we don’t expect or want them, we respond with fear, rage, or simple annoyance. It’s no longer an animal. It’s a pest.At the intersection of science, history, and narrative journalism, Pests is not a simple call to look closer at our urban ecosystem. It’s not a natural history of the animals we hate. Instead, this book is about us. It’s about what calling an animal a pest says about people, how we live, and what we want. It’s a story about human nature, and how we categorize the animals in our midst, including bears and coyotes, sparrows and snakes. Pet or pest? In many cases, it’s entirely a question of perspective.Bethany Brookshire’s deeply researched and entirely entertaining book will show readers what there is to venerate in vermin, and help them appreciate how these animals have clawed their way to success as we did everything we could to ensure their failure. In the process, we will learn how the pests that annoy us tell us far more about humanity than they do about the animals themselves.
