Invasion Biology


Book Description

There are many hypotheses describing the interactions involved in biological invasions, but it is largely unknown whether they are backed up by empirical evidence. This book fills that gap by developing a tool for assessing research hypotheses and applying it to twelve invasion hypotheses, using the hierarchy-of-hypotheses (HoH) approach, and mapping the connections between theory and evidence. In Part 1, an overview chapter of invasion biology is followed by an introduction to the HoH approach and short chapters by science theorists and philosophers who comment on the approach. Part 2 outlines the invasion hypotheses and their interrelationships. These include biotic resistance and island susceptibility hypotheses, disturbance hypothesis, invasional meltdown hypothesis, enemy release hypothesis, evolution of increased competitive ability and shifting defence hypotheses, tens rule, phenotypic plasticity hypothesis, Darwin's naturalization and limiting similarity hypotheses and the propagule pressure hypothesis. Part 3 provides a synthesis and suggests future directions for invasion research.




Global Biodiversity in a Changing Environment


Book Description

The scientific community has voiced two general concerns about the future of the earth. Firstly, climatologists and oceanographers have focused on the changes in our physical environment, ie climate, oceans, and air. And secondly, environmental biologists have addressed issues of conservation and the extinction of species. There is increasing evidence that these two broad concerns are intertwined and mutually dependent. Past changes in biodiversity have both responded to and caused changes in the earths environment. In its discussions of ten key terrestrial biomes and freshwater ecosystems, this volume uses our broad understanding of global environmental change to present the first comprehensive scenarios of biodiversity for the twenty-first century. Combining physical earth science with conservation biology, the book provides a starting-point for regional assessments on all scales. The book will be of interest to those concerned with guiding research on the changing environment of the earth and with planning future policy, especially in accordance with the Global Biodiversity Convention.

Tropical Rainforest Responses to Climatic Change


Book Description

This updated and expanded second edition of a much lauded work provides a current overview of the impacts of climate change on tropical forests. The authors also investigate past, present and future climatic influences on the ecosystems with the highest biodiversity on the planet. Tropical Rainforest Responses to Climatic Change, Second Edition, looks at how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. Shifting the emphasis on to ecological processes, e.g. how diversity is structured by climate and the subsequent impact on tropical forest ecology, provides the reader with a more comprehensive coverage. A major theme of the book is the interaction between humans, climate and forest ecology. The authors, all foremost experts in their fields, explore the long term occupation of tropical systems, the influence of fire and the future climatic effects of deforestation, together with anthropogenic emissions. Incorporating modelling of past and future systems paves the way for a discussion of conservation from a climatic perspective, rather than the usual plea to stop logging. This second edition provides an updated text in this rapidly evolving field. The existing chapters are revised and updated and two entirely new chapters deal with Central America and the effect of fire on wet forest systems. In the first new chapter, the paleoclimate and ecological record from Central America (Lozano, Correa, Bush) is discussed, while the other deals with the impact of fire on tropical ecosystems. It is hoped that Jonathon Overpeck, who has been centrally involved in the 2007 and 2010 IPCC reports, will provide a Foreword to the book.







Forests and Global Change


Book Description

Forests hold a significant proportion of global biodiversity and terrestrial carbon stocks and are at the forefront of human-induced global change. The dynamics and distribution of forest vegetation determines the habitat for other organisms, and regulates the delivery of ecosystem services, including carbon storage. Presenting recent research across temperate and tropical ecosystems, this volume synthesises the numerous ways that forests are responding to global change and includes perspectives on: the role of forests in the global carbon and energy budgets; historical patterns of forest change and diversification; contemporary mechanisms of community assembly and implications of underlying drivers of global change; and the ways in which forests supply ecosystem services that support human lives. The chapters represent case studies drawn from the authors' expertise, highlighting exciting new research and providing information that will be valuable to academics, students, researchers and practitioners with an interest in this field.




Tropical Environments


Book Description

Provides a comprehensive introduction to the complex systems of the tropics, covering a broad, cross-regional range of humid through to semi-arid tropical climate zones. Offers a balanced mix of biophysical and human management issues.




Economics of Coastal and Water Resources: Valuing Environmental Functions


Book Description

Most of the chapters in this volume are authored by staff or associates of the Centre for Social and Economic Research on the Global Environment (CSERGE). CSERGE is a research centre sponsored by the UK Economic and Social Research Council (ESRC), which specialises in interdisciplinary work focussed on environmental management issues. Weare grateful for the long term support that we have received from the ESRC. We would also like to acknowledge the efforts of Ann Dixon and SHin Pearce in the preparation of this volume. vii INTRODUCTION CHAPTER 1. ECOLOGICAL ECONOMICS AND COASTAL ZONE ECOSYSTEMS' VALUES: AN OVERVIEW. Turner, R. K. , Bateman, I. J. and Adger, W. N. 1. 1 Coastal zone pressure and sustainable management challenges Given the continued intensification of the process of globalisation - involving population growth, population density changes via urbanisation, industrial development, increased trade and capital flows, liberalisation of transnational corporation activity and lifestyle and attitudinal changes - coastal zones and their hydrologically linked catchment areas have come under heavy environmental pressure. The scale and extent of socio-economic activities have profound implications for the now coevolving natural and human systems and their complex interrelationships (Turner, Perrings and Folke, 1997). The consequences of this process of change manifest themselves across a range of spatial and temporal scales. Indeed the juxtaposition of different spatial, functional and temporal scales that is inherent in the catchment-coastal ecosystems-seas/oceans continuum poses particularly difficult challenges for both science and resource management/governance.
