ArachnidsSeptember 1999Mites
Ecology, Evolution and Behaviour
by David E Walter, Heather C Proctor
There are over 40 000 named species of mite, and if estimates for unnamed species are included, then up to 1 million may grace the planet. By comparison, there are approximately 40 000 species of vertebrates, half of them fish, alive today. Mites are predators, parasites, herbivores and detritivores. They live in the dark depths of the ocean, in the lungs of birds, on the leaves of rainforest plants, and in human clothes and bedding. They are vectors of disease, vital players in soil formation, and important agents of biological control. Despite the grand diversity of mites, these small arthropods are often overlooked, and even trained biologists can be unaware of their significance.This books aims to fill the gap in our understanding of these intriguing creatures. It surveys life cycles, feeding behaviour, reproductive biology and host-associations of mites, without requiring prior knowledge of their morphology or taxonomy. The text is richly illustrated with line drawings and photographs. Topics covered include evolution of mites and other arachnids, mites in soil and water, mites on plants and animals, sperm transfer and reproduction, and mites as models of ecological and evolutionary theories.

Insecticide & herbicide technologyDecember 2000Evaluating Indirect Ecological Effects of Biological Control
by Edited by Eric Wajnberg, John K Scott, Paul C Quimby
A major concern for biological control has always been the risk of indirect unwanted effects on the ecology of other organisms. Our understanding of the ecological and evolutionary processes underlying these effects has until now been limited and experimental methods sometimes lacking. This book presents the key papers from of the first International Organisation for Biological Control global symposium, held in Montpellier, France, in October 1999. It addresses the issues and concerns involved in biological control, and assesses the current status of evaluation of the ecological effects.

Forestry & silviculture: practice & techniquesDecember 2000Forests and Landscapes
Linking Ecology, Sustainability and Aesthetics
by Edited by Eric Wajnberg, John K Scott, Paul C Quimby
Forests are an important component in the visual appeal of landscapes. There is an increasing recognition of the importance of this subject among foresters and environmental scientists. Increasingly, forest resource managers must consider both the aesthetic consequences of timber harvesting operations and management plans and public perceptions of the sustainability of forest eco-system management.Written by world class authorities this book is the first to address this subject area. It consists of 17 chapters and is divided into six parts. The interdisciplinary nature of the book brings together not only foresters and ecologists, but also landscape architects, psychologists and philosophers. Contributors are leading research workers in their subjects, from Canada, the USA and UK.

Science & MathematicsNovember 2016Keys to the Tropical Fruit Flies of South-East Asia
(Tephritidae: Dacinae)
by Richard A I Drew, Meredith C Romig
Fruit flies are a major issue facing horticultural producers, and as global warming and species migration become more prevalent issues there is an urgent need for easy identification of these pests. A companion volume to the recently published “Tropical Fruit Flies of South-East Asia (Tephritidae: Dacinae)”, this book provides fully-illustrated keys for the identification of all currently-known Dacinae fruit flies. Focusing on south-east Asian fauna, it covers areas including India, Bhutan, Nepal, Sri Lanka, Myanmar, China, Taiwan, Japan, the Philippines, Palau, Vietnam, Thailand, Singapore, Malaysia and Indonesia. This major new reference work is produced by experts with over 80 years' combined research experience, and through simple identification information can help prevent these major pest species being introduced to new geographical areas. Of particular value to agriculture and quarantine officers responsible for the detection of new incursions, where early detection is both economical and essential to guarantee eradication, this book is also a valuable resource for researchers and students of agriculture and entomology. ; A companion to “Tropical Fruit Flies of South-East Asia (Tephritidae: Dacinae)”, this book provides fully-illustrated keys for the identification of all currently-known Dacinae fruit flies.

Insects (entomology)December 2013Tropical Fruit Flies of South-East Asia
(Tephritidae: Dacinae)
by Richard A I Drew, Meredith C Romig
As global warming and species migration become more prevalent issues, there is an urgent need for a text that provides comprehensive taxonomic details and geographic distributions of Dacinae fruit flies within south-east Asia. In particular, some of the major pest species of this region are being introduced on a regular basis to new geographical areas, causing widespread food security issues and economic hardship. Quarantine and horticultural organisations require detailed information on these fruit fly species in order to detect and eradicate any new incursions. This major new reference work details the taxonomic research into the subfamily Dacinae, which contains the tropical fruit flies of south-east Asia, as well as many other regions of the world. While focusing on south-east Asian fauna, all known species are included, through a study of the type material available in museums around the world. Specimens collected in major surveys conducted across Asia from 1983 to present have also been used to ensure a complete, in-depth review of this subfamily. Providing complete descriptions and artwork of all species of Dacinae recorded from the south-east Asian region for the first time, this book is written and illustrated by experts with over 80 years' combined research experience. Areas covered include: India, Bhutan, Nepal, Sri Lanka, Myanmar, China, Taiwan, Japan, the Philippines, Palau, Vietnam, Thailand, Singapore, Malaysia and Indonesia. It is an essential reference for departments of agriculture, researchers and students of entomology and quarantine, horticultural and chemical industry personnel worldwide. Key features: - 120 recently discovered species - 500 detailed drawings - Revision of all known species - Updated geographical distributions and host records - Accurate list and detailed information of all known pest species This book will be followed by Keys to Fruit Flies of South-East Asia.

Forestry & related industriesDecember 1998Forest Policy
International Case Studies
by Edited by Bill Wilson, G C van Kooten, Ian Vertinsky, Louise Arthur
Forest policy involves a complex balance of governmental, social and industrial objectives in an environment where the forests and the institutions are also constantly changing. Across the various forestry jurisdictions there is a wide variety of policy models that have evolved in response to specific societal demands, institutional structures and forest environments. This book is an examination of forest policy in a selection of major forestry jurisdictions, primarily the major competitors in world softwood markets. These include the United States, British Columbia, Alberta, New Zealand, Sweden, Finland, Chile and Russia. These regions represent systems operating with natural forests, plantation forests, initial forest endowments, second/third generation forests, public forestland ownership, private forestland ownership, open markets, highly structured markets, and various responses to sustainability. For each jurisdiction a brief overview to the economy, the contribution of forestry, the resource base, the composition of the forest industry and the major stakeholders is provided. The policy discussions include forest management, timber pricing and export policy, environmental standards, land ownership and use, and the institutional setting relating to government agencies, taxation, labour and capital. Comment is provided on the evolution of the existing policy structure and the chapters finish with an evaluation and prognosis for the jurisdiction. This book is a valuable reference source for forest policy practitioners, students of forestry and political economy and industrial decision-makers seeking to position their business in global forestry.
