Book Description
Winner, 2011 Book Award, The Wildlife Society2009 Outstanding Academic Title, Choice Ernst and Lovich’s thoroughly revised edition of this classic reference provides the most updated information ever assembled on the natural histories of North American turtles. From diminutive mud turtles to giant alligator snappers, two of North America’s most prominent experts describe the turtles that live in the fresh, brackish, and marine waters north of Mexico. Incorporating the explosion of new scientific information published on turtles over the past fifteen years—including the identification of four new species—Ernst and Lovich supply comprehensive coverage of all fifty-eight species, with discussions of conservation status and recovery efforts. Each species account contains information on identification, genetics, fossil record, distribution, geographic variation, habitat, behavior, reproduction, biology, growth and longevity, food habits, populations, predators, and conservation status. The book includes range maps for freshwater and terrestrial species, a glossary of scientific names, an extensive bibliography for further research, and an index to scientific and common names. Logically organized and richly illustrated—with more than two hundred color photographs and fifty-two maps—Turtles of the United States and Canada remains the standard for libraries, museums, nature centers, field biologists, and professional and amateur herpetologists alike.

Book Description
Small enough to carry in a backpack, this comprehensive guide explores the many diverse natural communities of Michigan, providing detailed descriptions, distribution maps, photographs, lists of characteristic plants, suggested sites to visit, and a dichotomous key for aiding field identification. This is a key tool for those seeking to understand, describe, document, conserve, and restore the diversity of natural communities native to Michigan.

Book Description
Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water, feces, or air) without the prior isolation of any target organism. The analysis of environmental DNA has the potential of providing high-throughput information on taxa and functional genes in a given environment, and is easily amenable to the study of both aquatic and terrestrial ecosystems. It can provide an understanding of past or present biological communities as well as their trophic relationships, and can thus offer useful insights into ecosystem functioning. There is now a rapidly-growing interest amongst biologists in applying analysis of environmental DNA to their own research. However, good practices and protocols dealing with environmental DNA are currently widely dispersed across numerous papers, with many of them presenting only preliminary results and using a diversity of methods. In this context, the principal objective of this practical handbook is to provide biologists (both students and researchers) with the scientific background necessary to assist with the understanding and implementation of best practices and analyses based on environmental DNA.

Book Description
Freshwater turtles and goldfish can survive for several days without oxygen, some diving turtles for several months; hibernating animals can exist without food for long periods; others can survive extreme conditions such as desiccation, freezing, and thawing. These creatures are, in effect, self-sustaining life-support systems, with a mysterious ability to regulate their own metabolisms. These capabilities raise important questions, which Hochachka and Guppy explore in this seminal new book. What mechanisms turn down (or off) cell metabolism and other cell functions? How does an animal such as an opossum know when to activate mechanisms for slowing or stopping tissue and organ functions? How does it know when to turn them on again? How extensive is metabolic arrest as a defense against harsh environmental conditions? Can we decipher universal principles of metabolic arrest from available data? The lessons to be learned are of potentially great interest to clinicians, because the authors provide a theoretical framework in which to organize an attack on the all-too-practical problem of protecting tissues against hypoxia. Areas that may be influenced include research on cardiac arrest, strokes, acute renal failure, liver ischemia, lung injury, respiratory defense syndrome, claudication, shock, and organ transplant. Investigation of other metabolic arrest mechanisms may be similarly useful in both clinical and agricultural fields. This is a pioneering book of great use to biomedical/clinical researchers and to biologists, biochemists, and physiologists generally.

Book Description
Once a familiar backyard visitor in many parts of the United States and Mexico, the box turtle is losing the battle against extinction. In North American Box Turtles, C. Kenneth Dodd, Jr., has written the first book-length natural history of the twelve species and subspecies of this endangered animal. This volume includes comprehensive information on the species’ evolution, behavior, courtship and reproduction, habitat use, diet, population structure, systematics, and disease. Special features include color photos of all species, subspecies, and their habitats; a simple identification guide to both living and fossil species; and a summary of information on fossil Terrapene and Native uses of box turtles. End-of-chapter sections highlight future research directions, including the need for long-term monitoring and observation of box turtles within their natural habitat and conservation applications. A glossary and a bibliography of literature on box turtles accompany the text. All royalties from the sales of this volume will go to the Chelonian Research Foundation, a nonprofit foundation for the conservation of turtles.

Book Description
Urbanization affects wetlands in direct and indirect ways. Over the past several decades it has become increasingly apparent that unmanaged runoff is the primary threat to the country's watershed resources. Wetlands and Urbanization: Implications for the Future is the result of a ten year research project focused on the understanding and managing the impacts of urban stormwater on wetlands. The book documents the background, methods, and results of the research and uses the information to draw conclusions about managing wetland ecosystems in urban areas. The project culminates in a set of comprehensive guidelines for the management of wetland hydrology. While the focus of this research is regional in nature, its applications are broad. First, the research shows how to measure and assess the impact of urbanization on wetlands. Secondly, it presents scientific approaches available for use in an integrated assessment of wetland condition. And thirdly, it provides guidelines for biomonitoring wetlands using multiple indicators. Wetlands and Urbanization presents an integrated watershed approach to the scientific evaluation of the impact of landscape urbanization on wetland functions. It associates the source of impact (the landscape) with the sink (the wetland), relates findings to implications for future planning and management of watersheds and provides a model for future comprehensive investigations of wetland impacts from urbanization.
