Brief History of Herpetology in the Museum of Vertebrate Zoology, University of California, Berkeley, with a List of Type Specimens of Recent Amphibians and Reptiles

Javier A. Rodriguez-Robles

The Museum of Vertebrate Zoology (MVZ), located on the campus of the University of California, Berkeley, is a leading center of herpetological research in the United States. This monograph offers a brief account of the principal figures associated with the collection and of the most important events in the history of herpetology in the MVZ during its first 93 years, and lists all type specimens of recent amphibians and nonavian reptiles in the collection.

Although the MVZ has existed since 1908, until 1945 there was no formal curator for the collection of amphibians and nonavian reptiles. Since that time Robert C. Stebbins, David B. Wake, Harry W. Greene, Javier A. Rodríguez-Robles (in an interim capacity), and Craig Moritz have served in that position.

The herpetological collection of the MVZ was begun on March 13, 1909, with a collection of approximately 430 specimens from southern California and as of December 31, 2001, contained 232,254 specimens. Taxonomically, the collection is strongest in salamanders, accounting for 99,176 specimens, followed by "lizards" (squamate reptiles other than snakes and amphisbaenians, 63,439), frogs (40,563), snakes (24,937), turtles (2,643), caecilians (979), amphisbaenians (451), crocodilians (63), and tuataras (3). Whereas the collection's emphasis historically has been on the western United States and on California in particular, representatives of taxa from many other parts of the world are present.

The 1,765 type specimens in the MVZ comprise 120 holotypes, three neotypes, three syntypes, and 1,639 paratopotypes and paratypes; 83 of the holotypes were originally described as full species. Of the 196 amphibian and nonavian reptilian taxa represented by type material, most were collected in México (63) and California (USA, 54).

The Appendix of the monograph presents a list of curators, graduate and undergraduate students, postdoctoral fellows, research associates, research assistants, curatorial associates, curatorial assistants, and visiting faculty who have conducted research on the biology of amphibians and reptiles while in residence in the Museum of Vertebrate Zoology as of December 31, 2001.

Brutes or Angels

Human Possibility in the Age of Biotechnology

James T. Bradley

A guide to the rapidly progressing Age of Biotechnology, Brutes or Angels provides basic information on a wide array of new technologies in the life sciences, along with the ethical issues raised by each.

With stem cell research, Dolly the cloned sheep, in vitro fertilization, age retardation, and pharmaceutical mind enhancement, humankind is now faced with decisions that it has never before had to consider. The thoughtfulness, or lack of it, that we bring to those decisions will largely determine the future character of the living world.

Brutes or Angels will facilitate informed choice making about the personal use of biotechnologies and the formulation of public policies governing their development and use. Ten biotechnologies that impact humans are considered: stem cell research, embryo selection, human genomics, gene therapies, human reproductive cloning, age retardation, cognition enhancement, the engineering of nonhuman organisms, nanobiology, and synthetic biology.

With deft and assured use of metaphors, analogies, diagrams, and photographs, James T. Bradley introduces important biological principles and the basic procedures used in biotechnology. Various ethical issues--personhood, personal identity, privacy, ethnic discrimination, distributive justice, authenticity and human nature, and the significance of mortality in the human life cycle--are presented in a clear and unbiased manner. Personal reflection and group dialogue are encouraged by questions at the end of each chapter, making this book not only a general guide to better informed and nuanced thinking on these complex and challenging topics but also an appropriate text for bioethics courses in university science departments and for adult education classes.

Standing at the beginning of the twenty-first century, with burgeoning abilities to enhance and even create life in ways unimaginable just a few decades ago, humans have an awesome responsibility to themselves and other species. Brutes or Angelsinvites us to engage each other in meaningful dialogue by listening, gathering information, formulating thoughtful views, and remaining open to new knowledge and ethical argumentation.

The Bulb Hunter

Chris Wiesinger

Dubbed the Bulb Hunter in a 2006 New York Times feature story, Chris Wiesinger took his passion for bulbs to vacant lots, abandoned houses, cemeteries, and construction sites throughout the South in search of botanical survivors whose descendants had never seen the inside of a big-box chain store. The vintage specimens Wiesinger sought came from hardy, historic stock, adapted to human neglect and hot climates, reappearing faithfully over decades without care or cultivation.

Traveling back roads, speaking to strangers, looking for the telltale color of a remnant iris or lily, Wiesinger started digging, then began trying to grow and share the bulbs he collected. From its humble beginnings on an East Texas sweet potato farm, his Southern Bulb Company has now grown into a full-fledged business known throughout the world, propagating and selling the rare, tough, heritage plants Wiesinger still seeks out and champions.

Nicknamed “Flower” by his fellow cadets at Texas A&M University, Wiesinger relates his adventures in bulb hunting, telling stories of the bulbs he has discovered and weaving in his own life story as a student, plantsman, and small business owner. He then teams with veteran horticulturist William C. Welch to provide advice on how to grow and appreciate the bulbs that have been rescued and reintroduced. This “primer” gives gardeners information on what bulbs to grow where, when to plant them and when they bloom, and how to incorporate them with other plants in the landscape.

Finally, Welch describes how bulbs have enhanced his personal gardens and brought him and Wiesinger together in the common cause of heirloom gardening. Entertaining, informative, and loaded with beautiful photographs, The Bulb Hunter is sure to be a favorite of gardeners and plant lovers everywhere.

The Calculus of Selfishness:

Karl Sigmund

How does cooperation emerge among selfish individuals? When do people share resources, punish those they consider unfair, and engage in joint enterprises? These questions fascinate philosophers, biologists, and economists alike, for the "invisible hand" that should turn selfish efforts into public benefit is not always at work. The Calculus of Selfishness looks at social dilemmas where cooperative motivations are subverted and self-interest becomes self-defeating. Karl Sigmund, a pioneer in evolutionary game theory, uses simple and well-known game theory models to examine the foundations of collective action and the effects of reciprocity and reputation.

Focusing on some of the best-known social and economic experiments, including games such as the Prisoner's Dilemma, Trust, Ultimatum, Snowdrift, and Public Good, Sigmund explores the conditions leading to cooperative strategies. His approach is based on evolutionary game dynamics, applied to deterministic and probabilistic models of economic interactions.

Exploring basic strategic interactions among individuals guided by self-interest and caught in social traps, The Calculus of Selfishness analyzes to what extent one key facet of human nature--selfishness--can lead to cooperation.

California’s Fading Wildflowers

Lost Legacy and Biological Invasions

Richard A. Minnich

Early Spanish explorers in the late eighteenth century found springtime California covered with spectacular carpets of wildflowers from San Francisco to San Diego. Yet today, invading plant species have devastated this nearly forgotten botanical heritage. In this lively, vividly detailed work, Richard A. Minnich synthesizes a unique and wide-ranging array of sources—from the historic accounts of those early explorers to the writings of early American botanists in the nineteenth century, newspaper accounts in the twentieth century, and modern ecological theory—to give the most comprehensive historical analysis available of the dramatic transformation of California's wildflower prairies. At the same time, his groundbreaking book challenges much current thinking on the subject, critically evaluating the hypothesis that perennial bunchgrasses were once a dominant feature of California's landscape and instead arguing that wildflowers filled this role. As he examines the changes in the state's landscape over the past three centuries, Minnich brings new perspectives to topics including restoration ecology, conservation, and fire management in a book that will change our of view of native California.

Caterpillars of Eastern North America

A Guide to Identification and Natural History

David L. Wagner

This lavishly illustrated guide will enable you to identify the caterpillars of nearly 700 butterflies and moths found east of the Mississippi. The more than 1,200 color photographs and two dozen line drawings include numerous exceptionally striking images. The giant silk moths, tiger moths, and many other species covered include forest pests, common garden guests, economically important species, and of course, the Mescal Worm and Mexican Jumping Bean caterpillars. Full-page species accounts cover almost 400 species, with up to six images per species including an image of the adult plus succinct text with information on distribution, seasonal activity, foodplants, and life history. These accounts are generously complemented with additional images of earlier instars, closely related species, noteworthy behaviors, and other intriguing aspects of caterpillar biology.

Many caterpillars are illustrated here for the first time. Dozens of new foodplant records are presented and erroneous records are corrected. The book provides considerable information on the distribution, biology, and taxonomy of caterpillars beyond that available in other popular works on Eastern butterflies and moths. The introductory chapter covers caterpillar structure, life cycles, rearing, natural enemies, photography, and conservation. The section titled "Caterpillar Projects" will be of special interest to educators.

Given the dearth of accessible guides on the identification and natural history of caterpillars, Caterpillars of Eastern North America is a must for entomologists and museum curators, forest managers, conservation biologists and others who seek a compact, easy-to-use guide to the caterpillars of this vast region.

Chance in Biology

Using Probability to Explore Nature

Mark Denny

Life is a chancy proposition: from the movement of molecules to the age at which we die, chance plays a key role in the natural world. Traditionally, biologists have viewed the inevitable "noise" of life as an unfortunate complication. The authors of this book, however, treat random processes as a benefit. In this introduction to chance in biology, Mark Denny and Steven Gaines help readers to apply the probability theory needed to make sense of chance events--using examples from ocean waves to spiderwebs, in fields ranging from molecular mechanics to evolution.

Through the application of probability theory, Denny and Gaines make predictions about how plants and animals work in a stochastic universe. Is it possible to pack a variety of ion channels into a cell membrane and have each operate at near-peak flow? Why are our arteries rubbery? The concept of a random walk provides the necessary insight. Is there an absolute upper limit to human life span? Could the sound of a cocktail party burst your eardrums? The statistics of extremes allows us to make the appropriate calculations. How long must you wait to see the detail in a moonlit landscape? Can you hear the noise of individual molecules? The authors provide answers to these and many other questions.

After an introduction to the basic statistical methods to be used in this book, the authors emphasize the application of probability theory to biology rather than the details of the theory itself. Readers with an introductory background in calculus will be able to follow the reasoning, and sets of problems, together with their solutions, are offered to reinforce concepts. The use of real-world examples, numerous illustrations, and chapter summaries--all presented with clarity and wit--make for a highly accessible text. By relating the theory of probability to the understanding of form and function in living things, the authors seek to pique the reader's curiosity about statistics and provide a new perspective on the role of chance in biology.
