This benchmark volume documents in comprehensive detail a major environmental crisis: rapidly declining amphibian populations and the disturbing developmental problems that are increasingly prevalent within many amphibian species. Horror stories on this topic have been featured in the scientific and popular press over the past fifteen years, invariably asking what amphibian declines are telling us about the state of the environment. Are declines harbingers of devastated ecosystems or simply weird reflections of a peculiar amphibian world? This compendium-presenting new data, reviews of current literature, and comprehensive species accounts-reinforces what scientists have begun to suspect, that amphibians are a lens through which the state of the environment can be viewed more clearly. And, that the view is alarming and presages serious concerns for all life, including that of our own species. The first part of this work consists of more than fifty essays covering topics from the causes of declines to conservation, surveys and monitoring, and education. The second part consists of species accounts describing the life history and natural history of every known amphibian species in the United States.

Lake Okoboji in northwest Iowa is the jewel of the Iowa Great Lakes. A region of wetlands formed by prairie potholes, the area is rich with lakes, sloughs, fens, creeks, prairies, and kettleholes. In this readable and beautifully illustrated volume, Michael Lannoo presents an extensive natural history of Okoboji and its cherished wetlands that examines that world of our grandparents, compares it to today's world, and extrapolates to the world of our grandchildren.

The widespread appearance of frogs with deformed bodies has generated much press coverage over the past decade. Frogs with extra limbs or digits, missing limbs or digits, or misaligned appendages raise an alarming question: "Are deformed humans next?" Taking a fresh look at this disturbing environmental problem, this reference provides a balanced overview of the science behind the malformed frog phenomenon. Bringing together data from ecology, parasitology, and other disciplines, Michael Lannoo considers the possible causes of these deformities, tells which frogs have been affected, and addresses questions about what these malformations might mean to human populations. Featuring high-quality radiographic images, Malformed Frogs suggests that our focus should be on finding practical solutions, a key component of which will be controlling chemical, nutrient, and pesticide runoff into wetlands.

Aldo Leopold and Ed Ricketts are giants in the history of environmental awareness. They were born ten years and only about 200 miles apart and died within weeks of each other in 1948. Yet they never met and they didn't read each other's work. This illuminating book reveals the full extent of their profound and parallel influence both on science and our perception of natural world today. In a lively comparison, Michael J. Lannoo shows how deeply these two ecological luminaries influenced the emergence both of environmentalism and conservation biology. In particular, he looks closely at how they each derived their ideas about the possible future of humanity based on their understanding of natural communities. Leopold and Ricketts both believed that humans cannot place themselves above earth's ecosystems and continue to survive. In light of climate change, invasive species, and collapsing ecosystems, their most important shared idea emerges as a powerful key to the future.

Field biology is enjoying a resurgence due to several factors, the most important being the realization that there is no ecology, no conservation, and no ecosystem restoration without an understanding of the basic relationships between species and their environments-an understanding gleaned only through field-based natural history. With this resurgence, modern field biologists find themselves asking fundamental existential questions such as: Where did we come from? What is our story? Are we part of a larger legacy? In This Land Is Your Land, seasoned field biologist Michael J. Lannoo answers these questions and more in a tale rooted in the people and institutions of the Midwest. It is a story told from the ground up, a rubber boot-based natural history of field biology in America. Lannoo illuminates characters such as John Wesley Powell, William Temple Hornaday, and Olaus and Adolph Murie-homegrown midwestern field biologists who either headed east to populate major research centers or went west to conduct their fieldwork along the frontier. From the pioneering work of Victor Shelford, Henry Chandler Cowles, and Aldo Leopold to contemporary insights from biologists such as Jim Furnish and historians such as William Cronon, Lannoo's unearthing of American-and particularly midwestern-field biologists reveals how these scientists influenced American ecology, conservation biology, and restoration ecology, and in turn drove global conservation efforts through environmental legislation and land set-asides. This Land Is Your Land reveals the little-known legacy of midwestern field biologists, whose ethos and discoveries have enabled us to preserve and understand not just their land, but all lands.

Women are contributing to disciplines once the sole domain of men. Field biology has been no different. The history of women field biologists, embedded in a history largely made and recorded by men, has never been written. Compilations of biographies have been assembled, but the narrative-their story-has never been told. In part, this is because many expressed their passion for nature as writers, artists, collectors, and educators during eras when women were excluded from the male-centric world of natural history and science. The history of women field biologists is intertwined with men's changing views of female intellect and with increasing educational opportunities available to women. Given the preponderance of today's professional female ecologists, animal behaviorists, systematists, conservation biologists, wildlife biologists, restoration ecologists, and natural historians, it is time to tell this story-the challenges and hardships they faced and still face, and the prominent role they have played and increasingly play in understanding our natural world. For a broader perspective, we profile selected European women field biologists, but our primary focus is the journey of women field biologists in North America. Each woman highlighted here followed a unique path. For some, personal wealth facilitated their work; some worked alongside their husbands. Many served as invisible assistants to men, receiving little or no recognition. Others were mavericks who carried out pioneering studies and whose published works are still read and valued today. All served as inspiration and proved to the women who would follow that women are as capable as men at studying nature in nature. Their legacy lives on today. The 75 female field biologists interviewed for this book are further testament that women have the intellect, stamina, and passion for fieldwork.

Some 300 species of amphibians inhabit North America. The past two decades have seen an enormous growth in interest about amphibians and an increased intensity of scientific research into their fascinating biology and continent-wide distribution. This atlas presents the spectacular diversity of North American amphibians in a geographic context. It covers all formally recognized amphibian species found in the United States and Canada, many of which are endangered or threatened with extinction. Illustrated with maps and photos, the species accounts provide current information about distribution, habitat, and conservation. Researchers, professional herpetologists, and anyone intrigued by amphibians will value North American Amphibians as a guide and reference.
