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.

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.

Discover why we must protect the Amazon from climate change. Bursting with all kinds of life, the Amazon is one of the most incredible places on Earth. This richly illustrated picture book brings to life this extraordinary region for young children, exploring its tropical rainforest and scenic landscapes. It showcases the lush wildlife, diverse communities and life-saving medicines that can all be found there and therefore why it is so important that we act to protect this special part of the planet from the impact of climate change.

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.
