There is a growing concern that many important ecosystems, such as coral reefs and tropical rain forests, might be at risk of sudden collapse as a result of human disturbance. At the same time, efforts to support the recovery of degraded ecosystems are increasing, through approaches such as ecological restoration and rewilding. Given the dependence of human livelihoods on the multiple benefits provided by ecosystems, there is an urgent need to understand the situations under which ecosystem collapse can occur, and how ecosystem recovery can best be supported. To help develop this understanding, this volume provides the first scientific account of the ecological mechanisms associated with the collapse of ecosystems and their subsequent recovery. After providing an overview of relevant theory, the text evaluates these ideas in the light of available empirical evidence, by profiling case studies drawn from both contemporary and prehistoric ecosystems. Implications for conservation policy and practice are then examined.

Hedges and field margins are important wildlife habitats and deliver a range of ecosystem services, and their value is increasingly recognised by ecologists. This book reviews and assesses the current state of research on hedgerows and associated field margins.With the intensification of agriculture in the second half of the last century, field sizes were increased by amalgamation and the rooting out of hedges, synthetic pesticide and inorganic fertiliser use increased, and traditional methods of hedge management were largely abandoned. The book is split into two main sections. The first deals with definitions, current and historic management, the impact of pesticides, the decline in hedge stock and condition, and new approaches to hedge evaluation using remote sensing techniques. The second section explores the pollination and biological pest control benefits provided by hedges and field margins and examines the ecology of some of the major groups that are found in hedgerows and field margins: butterflies and moths, carabid beetles, mammals, and birds. A case study on birds and invertebrates from a research farm managed as a commercial enterprise, but which attempts to farm with wildlife in mind, brings these themes together. A final chapter introduces the neglected area of hedges in the urban environment.The book will be of great interest to advanced students, researchers and professionals in ecology, agriculture, wildlife conservation, natural history, landscape, environmental and land management.

As both the societies and the world in which we live face increasingly rapid and turbulent changes, the concept of resilience has become an active and important research area. Reflecting the very latest research, this book provides a critical review of the ways in which resilience of social-ecological systems, and the ecosystem services they provide, can be enhanced. With contributions from leaders in the field, the chapters are structured around seven key principles for building resilience: maintain diversity and redundancy; manage connectivity; manage slow variables and feedbacks; foster complex adaptive systems thinking; encourage learning; broaden participation; and promote polycentric governance. The authors assess the evidence in support of these principles, discussing their practical application and outlining further research needs. Intended for researchers, practitioners and graduate students, this is an ideal resource for anyone working in resilience science and for those in the broader fields of sustainability science, environmental management and governance.

This volume provides a series of essays on open questions in ecology with the overarching goal being to outline to the most important, most interesting or most fundamental problems in ecology that need to be addressed. The contributions span ecological subfields, from behavioral ecology and population ecology to disease ecology and conservation and range in tone from the technical to more personal meditations on the state of the field. Many of the chapters start or end in moments of genuine curiosity, like one which takes up the question of why the world is green or another which asks what might come of a thought experiment in which we "turn-off" evolution entirely.
