The management and conservation of natural populations relies heavily on concepts and results generated from models of population dynamics. Yet this is the first book to present a unified and coherent explanation of the underlying theory. This novel text begins with a consideration of what makes a good state variable, progressing from the simplest models (those with a single variable such as abundance or biomass) to more complex models with other key variables of population structure (including age, size, life history stage, and space). Throughout the book, attention is paid to concepts such as population variability, population stability, population viability/persistence, and harvest yield. Later chapters address specific applications to conservation such as recovery planning for species at risk, fishery management, and the spatial management of marine resources. Population Dynamics for Conservation is suitable for graduate-level students. It will also be valuable to academic and applied researchers in population biology. This overview of population dynamic theory can serve to further their population research, as well as to improve their understanding of population management.

Natural Resources Conservation and Advances for Sustainability addresses the latest challenges associated with the management and conservation of natural resources. It presents interdisciplinary approaches to promote advances in solving these challenges. By examining what has already been done and analyzing it in the context of what still needs to be done, particularly in the context of latest technologies and sustainability, the book helps to identify ideal methods for natural resource management and conservation. Each chapter begins with a graphical abstract and presents complicated or detailed content in the form of figures or tables. In addition, the book compares the latest techniques with conventional techniques and troubleshoots conventional methods with modifications, making it a practical resource for researchers in environmental science and natural resource management.

Throughout the world people are concerned about the demise of tropical forests and their wildlife. Hunting by forest-dwelling people has a dramatic effect on wildlife in many tropical forests, frequently driving species to local extinction, with devastating implications for other species and the health of the forests themselves. But wildlife is an important source of protein and cash for rural peoples. Can hunting be managed to conserve biological communities while meeting human needs? Are hunting rates as practiced by tropical forest peoples sustainable? If not, what are the biological, social, and cultural implications of this failure? Answering these questions is ever more important as national and international agencies seek to integrate the development of local peoples with the conservation of tropical forest systems and species.

This book presents a wide array of studies that examine the sustainability of hunting as practiced by rural peoples. Comprising work by both biological and social scientists, "Hunting for Sustainability in Tropical Forests" provides a balanced viewpoint on the ecological and human aspects of this hunting. The first section examines the effects of hunting on wildlife in tropical forests throughout the world. The next section looks at the importance of hunting to local communities. The third section looks at institutional challenges of resource management, while the fourth draws on economic perspectives to understand both hunting and sustainability. A final section provides synthesis and summary of the factors that influence sustainability and the implications for management.

Drawing on examples from Ecuador to Congo-Zaire to Sulawesi, "Hunting for Sustainability in Tropical Forests" will be a valuable resource to policymakers, conservation organizations, and students and scholars of biology, ecology, and anthropology.

This review of Pennsylvania's conservation efforts is the first book to focus exclusively on the state's vertebrates of concern.

The 133 species of reptiles, amphibians, birds, and mammals discussed in this book are Pennsylvania's most vulnerable terrestrial vertebrates. Each species is described in a full account that details basic biology and includes photographs and range maps. The accompanying narratives focus on conservation priorities, research needs, and management recommendations. Featuring information compiled from a broad array of sources and by contributors who are recognized authorities on their respective species, this volume is a model for wildlife conservation across much of the northeastern United States.

A road map that reveals the Keystone State's most sensitive species and what can be done to manage and conserve these important natural resources, "Terrestrial Vertebrates of Pennsylvania" is a valuable tool for wildlife managers, conservationists, and naturalists.

Notwithstanding the importance of modern technology, fieldwork remains vital, not least through helping to inspire and educate the next generation. Fieldwork has the ingredients of intellectual curiosity, passion, rigour and engagement with the outdoor world - to name just a few. You may be simply noting what you see around you, making detailed records, or carrying out an experiment; all of this and much more amounts to fieldwork. Being curious, you think about the world around you, and through patient observation develop and test ideas. Forty contributors capture the excitement and importance of fieldwork through a wide variety of examples, from urban graffiti to the Great Barrier Reef. Outdoor learning is for life: people have the greatest respect and care for their world when they have first-hand experience of it. The Editors are donating all royalties due to them to the environmental charity, The Field Studies Council, to support student fieldwork at the Council's field centres.
