Malformed Frogs

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.

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 wome...

North American Amphibians

"The frogs, toads, salamanders, and newts that inhabit North America, numbering nearly 300 species, represent immense variation in form, habitat, distribution and ecology. This volume discusses the diversity of these animals in relation to the historical geography of the North American continent and portrays all of the formally recognized amphibian species to be found in the United States and Canada within a geographical context. Each species is presented with a color photograph, an account of its range, habitat and conservation status, and an up-to-date, full color range map that depicts its known occurrences in relation to the topography of the landscape. This volume reflects the enormous growth in interest about amphibians and increased intensity of scientific research into their biology and distribution that has occurred during the past two decades"--

"The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been adde...

Leopold's Shack and Ricketts's Lab

"Leopold's Shack and Ricketts's Lab brings fresh insight to the fertile ideas and writings of two innovators of early twentieth century ecology. In this insightful and important book, Michael J. Lannoo enriches the legacies of Leopold and Ricketts as early conservation-minded environmentalists and suggests that there is still much to be learned from them."--Katharine A. Rodger, editor of Breaking Through: Essays, Journals, and Travelogues of Edward F. Ricketts "Lannoo creatively explores an important story of compelling historical characters with a clear vision of their significance for today's readers."--Curt Meine, author of Aldo Leopold: His Life and Work
