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.

Much of what you’ve heard about plastic pollution may be wrong. Instead of a great island of trash, the infamous Great Pacific Garbage Patch is made up of manmade debris spread over hundreds of miles of sea—more like a soup than a floating garbage dump. Recycling is more complicated than we were taught: less than nine percent of the plastic we create is reused, and the majority ends up in the ocean. And plastic pollution isn’t confined to the open ocean: it’s in much of the air we breathe and the food we eat. In Thicker Than Water: The Quest for Solutions to the Plastic Crisis, journalist Erica Cirino brings readers on a globe-hopping journey to meet the scientists and activists telling the real story of the plastic crisis. From the deck of a plastic-hunting sailboat with a disabled engine, to the labs doing cutting-edge research on microplastics and the chemicals we ingest, Cirino paints a full picture of how plastic pollution is threatening wildlife and human health. Thicker Than Water reveals that the plastic crisis is also a tale of environmental injustice, as poorer nations take in a larger share of the world’s trash, and manufacturing chemicals threaten predominantly Black and low-income communities. There is some hope on the horizon, with new laws banning single-use items and technological innovations to replace plastic in our lives. But Cirino shows that we can only fix the problem if we face its full scope and begin to repair our throwaway culture. Thicker Than Water is an eloquent call to reexamine the systems churning out waves of plastic waste.

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.

How is South Africa going to sustain the cost of securing rhino while the belief continues to persist that the enemy lies elsewhere in Southeast Asia? The Walkers believe that the problem actually lies in South Africa’s own backyard. This book discusses corruption and the criminal justice system, the need for more community engagement and the costs of protection. It also looks at how far we have come since the rhino wars in the 1980s and the rhino trade debate.

We have to shift from the negative to an element of the positive. People are tired of seeing dead and dying rhino. There is some optimism due to the excellent work being undertaken by the state and the private sector at many levels in security, tourism, community involvement and environmental education, as well as NGO support.

Rhino Revolution testifies to the many people doing just that. The rhino war in South Africa has entered its 10th year, and last year saw 662 rhino killed in Kruger alone – and over 1000 in total for South Africa. Clive and Anton Walker, authors of the bestselling Rhino Keepers (2012), have once again come up with a fresh, new look at the ongoing rhino crisis. With magnificent photographs and afterwords by John Hanks and Yolan Friedman.

An indispensable manual for conservationists throughout the UK and much of mainland Europe. It provides conservation guidance on the twelve non-marine amphibian and reptile species native to the British Isles. It covers a wide range of issues, from advice on surveying to reintroductions. Reprint edition of 1861074506 published in 1998.

With Britain's islands holding more than three-quarters of the Earth's stock of heather moorland, it is an extraordinary fact that it stands as one of the world's rarest habitats. A landscape beloved by millions, it's renowned for the tranquillity and solace it provides - however, this tranquillity is an illusion. Britain's moorlands have, in less than a decade, moved from a position of benign consensus to the epicentre of the bitterest conflict within UK conservation. This insightful book sets out to examine and expose the hidden issues surrounding UK moorland conservation, giving a voice to the many people who work and live there and who feel that what they have to say is often ignored, if it's even heard at all. The fate of our uplands is in our hands, and it is important that an alternative narrative, from the perspective of the practitioners who have cared for these places for generations, are considered. It may be that those with power chose to ignore these facts and sweep them away, but at least now they cannot say they didn't know.
