Because carnivores are at the top of the food chain, it is often argued that protecting them will afford adequate protection to other taxa as well. In the past ten years, theoretical and empirical studies on carnivores have developed very quickly. This volume reviews and summarizes the current state of the field, describes limitations and opportunities for carnivore conservation, and offers a conceptual framework for future research and applied management. It will be of interest to students and researchers of conservation biology, mammalogy, animal behavior, ecology, and evolution.

Twice declared extinct, North America’s most endangered mammal species, the black-footed ferret (BFF), is making a comeback thanks to an evolving conservation regimen at more than thirty reintroduction sites across the continent. Lawrence Lenhart lingers at one such site in his proverbial backyard, the Aubrey Valley in northern Arizona. He clocks hundreds of hours behind the wheel, rolling over ranch ruts as he shines a spotlight over dusky sage steppe in the hopes of catching a fleck of emerald eyeshine. The beguiling weasel at the center of this book is more than a charismatic minifauna; it is the covert ambassador of a critical ecosystem that has dwindled to 1 percent of its former size. In a landscape menaced by habitat fragmentation, bacterial plague, settler colonialism, and soil death, a ferret must be resilient. Lenhart investigates the human efforts to sustain the species through monitoring, vaccination, captive breeding, and even cloning. Lenhart balances this lens of environmental witness with personal essaying that captures the parallel story of his wife’s pregnancy as he realizes the ferret’s conservation story is dramatically synchronized with her trimesters. In preparing to raise a child in the Anthropocene, Lenhart takes stock of his own ecosystem and finds something is amiss. Through an ethic of "deeper ecology," Lenhart must hone his ecological interest in the black-footed ferret to assure it isn’t overshadowed by his own paternal interests.

How does an understanding of the behavior of a given animal species contribute to its conservation? The answer has profound consequences for our efforts to conserve endangered species. Behaviour and Conservation links the extraordinary advances in behavioral ecology over the past thirty years with the new discipline of conservation biology. It shows how an evolutionary approach can help solve problems in practical conservation, and suggests a new direction for behavioral ecology. Leading authorities in animal behavior address the ways in which behavior and conservation interact, investigating the conservation impact of people, habitat loss and fragmentation, threats to wild populations of animals, conservation priorities, and the use of behavioral approaches for conservation applications.

Today's conservation literature emphasizes landscape ecology and population genetics without addressing the behavioral links that enable the long-term survival of populations. This book presents theoretical and practical arguments for considering behavior patterns in attempts to conserve biodiversity. It brings together prominent scientists and wildlife managers to address a number of issues, including the limits and potentials of behavioral research to conservation, the importance of behavioral variation as a component of biodiversity, and the use of animal behavior to solve conservation problems. Throughout, the text provides specific direction for research and management practices. The book is unique in its emphasis on conservation of wild populations as opposed to captive and reintroduced populations, where behavioral research has concentrated in the past.

'Wise, challenging and offering some unexpected laughter in the dark, this is a rational and insightful account of the sixth great extinction event. Peter Marren is a brilliant writer and a national treasure.' PATRICK BARKHAM 'Thoughtful, fascinating and very timely.' STEPHEN MOSS 'Important and thought-provoking.' CAROLINE LUCAS, GREEN PARTY MP 'Essential reading. Marren makes a page-turner out of Armageddon.' SIMON BARNES 'In his characteristic style Peter Marren has humanised the story of wildlife losses with humour and wit but also with his enormous knowledge and deep love for the living world.' MARK COCKER We are in the midst of an extinction event: the sixth mass extinction on earth and one entirely caused by mankind. All species become extinct sooner or later, but we have accelerated that natural process several hundredfold and now, it is happening right in front of our eyes. Extinction has a terrifying finality to it. And many species have already been lost to us forever; there is little we can do about that. What we can do, however, is reflect, remember, and ultimately acknowledge the unvarnished truth. We must see the natural world as it is, and not as we might want it to be. Our trajectory is one that has benefited one species alone - humankind. For all other beings, from mammals to fish, from birds to insects and coral, from plants to lichens and fungi, the future, for better or worse, is in our hands.

A portrait of a species on the brinkThe only bird species that lives exclusively in Florida, the Florida Scrub-Jay was once common across the peninsula. But as development over the last 100 years reduced the habitat on which the bird depends from 39 counties to three, the species became endangered. With a writer's eye and an explorer's spirit, Mark Walters travels the state to report on the natural history and current predicament of Florida's flagship bird. Tracing the millions of years of evolution and migration that led to the development of songbirds and this unique species of jay, Walters describes the Florida bird's long, graceful tail, its hues that blend from one to the next, and its notoriously friendly manner. He then focuses on the massive land-reclamation and canal-building projects of the twentieth century that ate away at the ancient oak scrub heartlands where the bird was abundant, reducing its population by 90 percent. Walters also investigates conservation efforts taking place today. On a series of field excursions, he introduces the people who are leading the charge to save the bird from extinction-those who gather for annual counts of the species in fragmented and overlooked areas of scrub; those who relocate populations of Scrub-Jays out of harm's way; those who survey and purchase land to create wildlife refuges; and those who advocate for the prescribed fires that keep scrub ecosystems inhabitable for the species. A loving portrayal of a very special bird, Florida Scrub-Jay is also a thoughtful reflection on the ethical and emotional weight of protecting a species in an age of catastrophe. Now is the time to act, says Walters, or we will lose the Scrub-Jay forever.

Some ecosystem management plans established by state and federal agencies have begun to shift their focus away from single-species conservation to a broader goal of protecting a wide range of flora and fauna, including species whose numbers are scarce or about which there is little scientific understanding. To date, these efforts have proved extremely costly and complex to implement. Are there alternative approaches to protecting rare or little-known species that can be more effective and less burdensome than current efforts? "Conservation of Rare or Little-Known Species" represents the first comprehensive scientific evaluation of approaches and management options for protecting rare or little-known terrestrial species. The book brings together leading ecologists, biologists, botanists, economists, and sociologists to classify approaches, summarize their theoretical and conceptual foundations, evaluate their efficacy, and review how each has been used. Contributors consider combinations of species and systems approaches for overall effectiveness in meeting conservation and ecosystem sustainability goals. They discuss the biological, legal, sociological, political, administrative, and economic dimensions by which conservation strategies can be gauged, in an effort to help managers determine which strategy or combination of strategies is most likely to meet their needs. Contributors also discuss practical considerations of implementing various strategies. "Conservation of Rare or Little-Known Species" gives land managers access to a diverse literature and provides them with the basic information they need to select approaches that best suit their conservation objectives and ecological context. It is an important new work for anyone involved with developing land management or conservation plans.

The planet is currently experiencing alarming levels of species loss caused in large part by intensified poaching and wildlife trafficking driven by expanding demand, for medicines, for food, and for trophies. Affecting many more species than just the iconic elephants, rhinos, and tigers, the rate of extinction is now as much as 1000 times the historical average and the worst since the dinosaurs died out 65 million years ago. In addition to causing irretrievable biodiversity loss, wildlife trafficking also poses serious threats to public health, potentially triggering a global pandemic. The Extinction Market explores the causes, means, and consequences of poaching and wildlife trafficking, with a view to finding ways of suppressing them. Vanda Felbab-Brown travelled to the markets of Latin America, South and South East Asia, and eastern and southern Africa, to evaluate the effectiveness of various tools, including bans on legal trade, law enforcement, and interdiction; allowing legal supply from hunting or farming; alternative livelihoods; anti- money-laundering efforts; and demand reduction strategies. This is an urgent book offering meaningful solutions to one of the world's most pressing crises.

A great many species are threatened by the expanding human population. Though the public generally favors environmental protection, conservation does not come without sacrifice and cost. Many decision makers wonder if every species is worth the trouble. Of what consequence would the extinction of, say, spotted owls or snail darters be? Are some species expendable?

Given the reality of limited money for conservation efforts, there is a compelling need for scientists to help conservation practitioners set priorities and identify species most in need of urgent attention. Ecology should be capable of providing guidance that goes beyond the obvious impulse to protect economically valuable species (salmon) or aesthetically appealing ones (snow leopards). Although some recent books have considered the ecosystem services provided by biodiversity as an aggregate property, this is the first to focus on the value of particular species. It provides the scientific approaches and analyses available for asking what we can expect from losing (or gaining) species.

The contributors are outstanding ecologists, theoreticians, and evolutionary biologists who gathered for a symposium honoring Robert T. Paine, the community ecologist who experimentally demonstrated that a single predator species can act as a keystone species whose removal dramatically alters entire ecosystem communities. They build on Paine's work here by exploring whether we can identify species that play key roles in ecosystems before they are lost forever. These are some of our finest ecologists asking some of our hardest questions.

Documenting the species that have emerged, disappeared and been reborn over the millennia since the Cambrian Explosion, Lost Animals is the story of life on Earth. Over 520 million years ago, all the major animal groups – molluscs, worms, crustaceans, vertebrates – appear in the fossil record in what is, geologically speaking, the blink of an eye. As well as the animals we're familiar with today, evolution also experimented with now-obsolete body forms. Once, the world was a blank slate, but as this slate filled up, some lines were erased while others carried on to this day. Beautifully illustrated with artist's interpretations, photographs of fossils and excavations and scientific drawings, Lost Animals brings back to life some of the most charismatic creatures to inhabit the planet, as well as those representing an important link or leap in evolutionary terms. Zoologist Dr John Whitfield discusses those species we have lost, are only just discovering and those thought extinct until rediscovered, and the attempts to conserve and resurrect others.

The quiet manatee has long been a flash point of frequent environmental debates. It is Florida's most famous endangered species, as well as its most controversial. Manatees appear on hundreds of license plates, attract hordes of tourists, and expose the uneasy relationships between science and the law and between freedom and responsibility like no other animal. As passions have flared and resentments have grown, the battle over manatee protection has evolved into a war, and no reporter has followed the story more closely than Craig Pittman, the first environmental writer to explore the complex history, culture, and science of the controversies and concerns surrounding this remarkable creature. With an abiding interest in the uncertain fate of this unique species, Manatee Insanity provides the first in-depth history of the attempts to provide legal protection for the manatee. Pittman follows Florida's gentle giants through time and space, detailing interactions with a variety of human actors, from Jacques-Yves Cousteau to Jeb Bush to Jimmy Buffett, from a popular children's book author to a federal lawman who dressed in a gorilla suit for the ultimate undercover assignment.
