The use of wildlife for food and other human needs poses one of the greatest threats to the conservation of biodiversity. Wildlife exploitation is also critically important to many people from a variety of cultures for subsistence and commerce. This book brings together international experts to examine interactions between the biology of wildlife and the divergent goals of people involved in hunting, fishing, gathering and culling wildlife. Reviews of theory show how sustainable exploitation is tied to the study of population dynamics, with direct links to reproductive rates, life histories, behaviour and ecology. As such theory is rarely put into practice to achieve sustainable use and effective conservation, Conservation of Exploited Species explores the many reasons for this failure and considers remedies to tackle them, including scientific issues such as how to incorporate uncertainty into estimations, as well as social and political problems that stem from conflicting goals in exploitation.

The potato (Solanum tuberosum L. ) tuber is a major food source in many countries of the world, and subsequently potato has been the target of a good deal of effort directed at engineering disease and herbicide tolerance, and improvements in various crop characteristics. Consequently investigations into the regulation of gene expression in tubers is relevant to these endeavours, as tubers are the main target organ for modification of gene expression. We have been interested in the regulation of genes in tubers for these reasons. Morphologically tubers are modified stems, which have enlarged radially by limited cell division and substantial expansion. At the molecular level, tuber development is characterised by a massive increase in starch deposition and the synthesis of a limited number of abundant proteins. These include proteinase inhibitors and a 40kd group of proteins called patatin, which are acyl hydrolases. Together these proteins account for over 50% of tuber proteins (reviewed by Bevan, 1991). The synthesis of these proteins has parallels to the synthesis of other somatic storage proteins, especially the VSP proteins of soybean. In both potato and soybean, removal of the sink for these proteins (tubers and pods, respectively) causes deposition in other tissues (Staswick, 1990). It is hypothesised that transcriptional control of the genes encoding these proteins is regulated in part by source-sink relationships of metabolites or other factors. In the case of VSPs, both amino acid levels and jasmonic acid play a major regulatory role (Staswick et aI.

This book presents a wide range of contributions addressing diverse aspects of biodiversity exploitation and conservation. These collectively provide a snapshot of ongoing action and state-of-the-art research, rather than a series of necessarily more superficial overviews. Examples presented here derive from studies in 17 countries including Africa, Asia, Europe, and North and South America. These reports will stimulate future work toward attaining a sustainable balance between the conservation and exploitation of biodiversity.

Human exploitation of other mammals has passed through three histori cal phases, distinct in their ecological significance though overlapping in time. Initially, Homo sapiens was a predator, particularly of herbivores but also of fur-bearing predators. From about 11 000 years ago, goats and sheep were domesticated in the Middle East, rapidly replacing gazelles and other game as the principal source of meat. The principal crops, including wheat and barley, were taken into agriculture at about the same time, and the resulting Neolithic farming culture spread slowly from there over the subsequent 10 500 years. In a few places such as Mexico, Peru and China, this Middle Eastern culture met and merged with agricultural traditions that had made a similar but independent transition. These agricultural traditions provided the essential support for the industrial revolution, and for a third phase of industrial exploita tion of mammals. In this chapter, these themes are drawn out and their ecological signifi cance is investigated. Some of the impacts of humans on other mammals require consideration on a world-wide basis, but the chapter concen trates, parochially, on Great Britain. What have been the ecological consequences of our exploitation of other mammals? 2. 2 HISTORICAL PHASES OF EXPLOITATION 2. 2. 1 Predatory man Our nearest relatives - chimpanzees, orang utans and gorillas - are essentially forest species, deriving most of their diet from the fruits of forest trees and the shoots and leaves of plants.

The underlying theme of this book is that a widespread, taxonomically diverse group of animals, important both from ecological and human resource perspectives, remains poorly understood and in delcine, while receiving scant attention from the ecological and conservation community. This volume proposes a comprehensive overview of the world's river turtles' ecology, conservation, and management. It begins with a categorization of taxa which inhabit flowing water habitats followed by information on their evolutionary and physical diversity and biogeography. Within the framework of ecology, the authors discuss the composition of river turtle communities in different types of lotic habitats and regions, population dynamics, movements, reproductive characteristics and behavior, predators, and feeding relationships. In a conservation and management section, the authors identify and evaluate the nature and intensity of factors which threaten river turtle survival--almost all of which involve direct human exploitation or indirect effects of human induced habitat alteration and degradation. They then list and evaluate the various schemes which have been proposed or employed to halt declines and restore populations, and make recommendations for future management plans for specific species and regions. In closing, they state their viewpoint concerning future research directions and priorities, and an evaluation of future prospects for survival of the world's river turtle species.

The book aims to further the debate on the impacts of fisheries policies in the Indian Ocean Region in order to facilitate a new regional policy direction. A key argument of the volume is that ecologically sustainable and socially just development and management of Indian Ocean fisheries require a paradigm shift in the perceptions and policies of major stakeholders. A central policy challenge is to identify a collective regional interest for fisheries and accordingly the development of integrated management policies that link ecology and society and which incorporate individuals, communities, agencies, states and regimes into a holistic cooperative endeavour. Successful ocean governance therefore requires greater inter-state and inter-agency consultation and cooperation, an improvement in linking national initiatives to local action, increased participation of local government and local communities and the enhancement of local capability. In order to achieve this overall goal requires either the enhancement of existing regional institutions or the creation of a new regional body.

Large Carnivores and the Conservation of Biodiversity brings together more than thirty leading scientists and conservation practitioners to consider a key question in environmental conservation: Is the conservation of large carnivores in ecosystems that evolved with their presence equivalent to the conservation of biological diversity within those systems? Building their discussions from empirical, long-term data sets, contributors including James A. Estes, David S. Maehr, Tim McClanahan, Andrès J. Novaro, John Terborgh, and Rosie Woodroffe explore a variety of issues surrounding the link between predation and biodiversity: What is the evidence for or against the link? Is it stronger in marine systems? What are the implications for conservation strategies? Large Carnivores and the Conservation of Biodiversity is the first detailed, broad-scale examination of the empirical evidence regarding the role of large carnivores in biodiversity conservation in both marine and terrestrial ecosystems. It contributes to a much more precise and global understanding of when, where, and whether protecting and restoring top predators will directly contribute to the conservation of biodiversity. Everyone concerned with ecology, biodiversity, or large carnivores will find this volume a unique and thought-provoking analysis and synthesis.
