Deep inside caves, at the bottoms of oceans and lakes, beneath the ground: these concealed habitats are absent of sunlight. This strange and fascinating world of complete darkness is not a solitary place--it is inhabited by millions of life forms. Yet most humans--creatures of daylight--have never seen any of them. Until now. In this fascinating--sometimes eerie--book, extreme wildlife photographer and scientist Danté Fenolio brings the denizens of these shadowy haunts into focus. Life in the Dark shows us the many ways in which life forms have adapted to lightless environments, including refinements of senses, evolution of unique body parts, and illumination using "biological flashlights." With more than 200 mesmerizing color photographs, Life in the Dark unveils bizarre creatures like the firefly squid, the giant Amazonian catfish, the Chinese cavefish, and even the human bot fly, which lives in the darkness beneath its host's skin. Fenolio's rich and vibrant images shed new light on the world's fascinating creatures of darkness.

Provides an up-to-date synthesis of the current state of knowledge regarding the biology and conservation risks faced by 45 of California's most sensitive amphibian and reptile species. With the goal of enhancing management based on the best available science, the authors developed a novel set of risk metrics to identify special concern species and the threats they face, including population declines, range size and restrictions, and ecological specializations and niche restrictions. In addition to detailed species accounts, this book provides a quantitative analysis of the conservation status and pressing management issues facing individual species and the state's amphibian and reptile fauna as a whole. The volume focuses on identifying threats, concrete recommendations for management and recovery, and future research needs. The text is complemented by detailed distribution maps, color photos, and graphs.

Integrating research into freshwater biodiversity and the role of keystone species, this fascinating book presents freshwater crayfish as representatives of human-exacerbated threats to biodiversity and conservation. It uses examples from these and other large decapod invertebrates to explore how communities function and are controlled, alongside the implications of human demands and conflicts over limited resources, notably the severe impacts on biodiversity. The discussion is structured around three key topics - the present situation of crayfish in world freshwater ecosystems, the applications of science to conservation management and knowledge transfer for successful crayfish management. It outlines the historic exploitation of crayfish, addressing the problems caused by invasive alien forms and explaining the importance of correct identification when dealing with conservation issues. Offering a global perspective on freshwater systems, the book ultimately highlights how the conservation of such large and long-lived species will help protect ecosystem quality in the future.

Australia and New Zealand are home to a remarkable and unique assemblage of flora and fauna. Sadly though, by virtue of their long isolation, and a naïve and vulnerable biota, both countries have suffered substantial losses to biodiversity since European contact. Bringing together the contributions of leading conservation biologists, Austral Ark presents the special features and historical context of Austral biota, and explains what is being conserved and why. The threatening processes occurring worldwide are discussed, along with the unique conservation problems faced at regional level. At the same time, the book highlights many examples of conservation success resulting from the innovative solutions that have been developed to safeguard native species and habitats in both New Zealand and Australia. Austral Ark fills an important gap regarding wildlife gains and declines, and how best to take conservation forward to keep this extraordinary area of the world thriving.

Animals such as wolves, sea otters, and sharks exert a disproportionate influence on their environment; dramatic ecological consequences can result when they are removed from--or returned to--an ecosystem. In The Wolf's Tooth, scientist and author Cristina Eisenberg explores the concept of "trophic cascades" and the role of top predators in regulating ecosystems. Her fascinating and wide-ranging work provides clear explanations of the science surrounding keystone predators and considers how this notion can help provide practical solutions for restoring ecosystem health and functioning. Eisenberg examines both general concepts and specific issues, sharing accounts from her own fieldwork to illustrate and bring to life the ideas she presents. She considers how resource managers can use knowledge about trophic cascades to guide recovery efforts, including how this science can be applied to move forward the bold vision of rewilding the North American continent. In the end, the author provides her own recommendations for local and landscape-scale applications of what has been learned about interactive food webs. At their most fundamental level, trophic cascades are powerful stories about ecosystem processes--of predators and their prey, of what it takes to survive in a landscape, of the flow of nutrients. The Wolf's Tooth is the first book to focus on the vital connection between trophic cascades and restoring biodiversity and habitats, and to do so in a way that is accessible to a diverse readership.

An award-winning author's quest to find and understand a creature as rare and enigmatic as any on Earth. In 1992, in a remote mountain range, a team of scientists discovered the remains of an unusual animal with exquisite long horns. It turned out to be a living species new to Western science -- a saola, the first large land mammal discovered in fifty years. Rare then and rarer now, a live saola had never been glimpsed by a Westerner in the wild when Pulitzer Prize finalist and nature writer William deBuys and conservation biologist William Robichaud set off to search for it in central Laos. Their team endured a punishing trek up and down white-water rivers and through mountainous terrain ribboned with the snare lines of armed poachers who roamed the forest, stripping it of wildlife. In the tradition of Bruce Chatwin, Colin Thubron, and Peter Matthiessen, The Last Unicorn chronicles deBuys's journey deep into one of the world's most remote places. It's a story rich with the joys and sorrows of an expedition into undiscovered country, pursuing a species as rare and elusive as the fabled unicorn. As is true with the quest for the unicorn, in the end the expedition becomes a search for something more: the essence of wildness in nature, evidence that the soul of a place can endure, and the transformative power of natural beauty.

What's the easiest way to tell species apart? Check their genitals. Researching private parts was long considered taboo, but scientists are now beginning to understand that the wild diversity of sex organs across species can tell us a lot about evolution. Schilthuizen invites readers to join him as he uncovers the ways the shapes and functions of genitalia have been molded by complex Darwinian struggles. He joyfully demonstrates that by learning about the private parts of animals the more humans can learn about their unique place in the diversity of life.
