First multi-year cumulation covers six years: 1965-70.
Plants are fundamental to life; they are used by all human groups and most animals. They provide raw materials, vitamins and essential nutrients and we could not survive without them. Yet access to plant use before the Neolithic can be challenging. In some places, plant remains rarely survive and reconstructing plant use in pre-agrarian contexts needs to be conducted using a range of different techniques. This lack of visible evidence has led to plants being undervalued, both in terms of their contribution to diet and as raw materials. This book outlines why the role of plants is required for a better understanding of hominin and pre-agrarian human life, and it offers a variety of ways in which this can be achieved. Wild Harvest is divided into three sections. In section 1 each chapter focuses on a specific feature of plant use by humans; this covers the role of carbohydrates, the need for and effects of processing methods, the role of plants in self-medication among apes, plants as raw materials, and the extent of evidence for plant use prior to the development of agriculture in the Near East. Section 2 comprises seven chapters which cover different methods available to obtain information on plants, and the third section has five chapters, each covering a topic related to ethnography, ethnohistory, or ethnoarchaeology, and how these can be used to improve our understanding of the role of plants in the pre-agrarian past.
Biological control is the suppression of pest populations using predators, parasitoids and pathogens. Historically, biological control has largely been on a trial-and-error basis, and has failed more often than it has succeeded. However by developing theories based upon fundamental population principles and the biological characteristics of the pest and agent, we can gain a much better understanding of when and how to use biological control. This book gathers together recent theoretical developments and provides a balanced guide to the important issues that need to be considered in applying ecological theory to biological control. It will be a source of productive and stimulating thought for all those interested in pest management, theoretical ecology and population biology.
This volume discusses environmental change, natural resource exploitation and the prospect for ecological sustainability in Southeast Asia. The contributors including sociologists, geographers, anthropologists, economists, political economists and historians, presents the findings of recent archival and field research mainly from ongoing programmes of team research based in European universities and institutes. Among the themes discussed are European and indigenous perceptions of the environment; historical processes of environmental change; the politics of resource use; ecotourism and development; deforestation and smallholding land-use strategies; migration and environmental degradation; disease environment and human geography; demography, sustainability and resource exploitation.
