Consisting of more than six thousand species, amphibians are more diverse than mammals and are found on every continent save Antarctica. Despite the abundance and diversity of these animals, many aspects of the biology of amphibians remain unstudied or misunderstood. The Ecology and Behavior of Amphibians aims to fill this gap in the literature on this remarkable taxon. It is a celebration of the diversity of amphibian life and the ecological and behavioral adaptations that have made it a successful component of terrestrial and aquatic ecosystems.
Synthesizing seventy years of research on amphibian biology, Kentwood D. Wells addresses all major areas of inquiry, including phylogeny, classification, and morphology; aspects of physiological ecology such as water and temperature relations, respiration, metabolism, and energetics; movements and orientation; communication and social behavior; reproduction and parental care; ecology and behavior of amphibian larvae and ecological aspects of metamorphosis; ecological impact of predation on amphibian populations and antipredator defenses; and aspects of amphibian community ecology. With an eye towards modern concerns, The Ecology and Behavior of Amphibians concludes with a chapter devoted to amphibian conservation.
An unprecedented scholarly contribution to amphibian biology, this book is eagerly anticipated among specialists.
Building on fourteen years of research, Margaret F. Kinnaird and Timothy G. O’Brien offer in Ecology and Conservation of Asian Hornbills the most up-to-date information on the evolution, reproduction, feeding ecology, and movement patterns of thirty-one species of Asian hornbills. The authors address questions of ecological functionality, ecosystem services, and keystone relationships, as well as the disturbing influence of forest loss and fragmentation on hornbills. Complemented by superb full-color images by renowned photographer Tim Laman that provide rare glimpses of hornbills in their native habitat and black-and-white illustrations by Jonathan Kingdon that highlight the intriguing aspects of hornbill behavior, Ecology and Conservation of Asian Hornbills will stand tall in the pantheon of natural history studies for years to come.
In recent times, the science of ecology has been rejuvenated and has moved to a central position in biology. This volume contains eighteen original, major contributions by leaders in the field, all associates of the late Robert MacArthur, whose work has stimulated many of the recent developments in ecology. The intellectual ferment of the field is reflected in these papers, which offer new models for ecological processes, new applications of theoretical and quantitative techniques, and new methods for analyzing and interpreting a wide variety of empirical data.
The first five chapters explore the evolution of species abundance and diversity (R. Levins, E. Leigh, J. MacArthur, R. May, and M. Rosenzweig). The theory of loop analysis is newly applied to understanding stability of species communities under both mendelian and group selection. Species abundance relations, population fluctuations, and continental patterns of species diversity are illustrated and interpreted theoretically. The next section examines the competitive strategies of optimal resource allocation variously employed in plant life histories (W. Schaffer and M. Gadgil), bird diets and foraging techniques (H. Hespenheide), butterfly seasonal flights (A. Shapiro), and forest succession examined by the theory of Markov processes (H. Horn).
The seven chapters of the third section study the structure of species communities, by comparing different natural communities in similar habitats (M. Cody, J. Karr and F. James, E. Pianka, J. Brown, J. Diamond), or by manipulating field situations experimentally (R. Patrick, J. Connell). The analyses are of communities of species as diverse as freshwater stream organisms, desert lizards and rodents, birds, invertebrates, and plants. These studies yield insights into the assembly of continental and insular communities, convergent evolution of morphology and of ecological structure, and the relative roles of predation, competition, and harsh physical conditions in limiting species ranges.
Finally, the two remaining chapters illustrate how ecological advances depend on interaction of theory with field and laboratory observations (G. E. Hutchinson), and how ecological studies such as those of this volume may find practical application to conservation problems posed by man's accelerating modification of the natural world (E. Wilson and E. Willis).
Ecologists can spend a lifetime researching a small patch of the earth, studying the interactions between organisms and the environment, and exploring the roles those interactions play in determining distribution, abundance, and evolutionary change. With so few ecologists and so many systems to study, generalizations are essential. But how do you extrapolate knowledge about a well-studied area and apply it elsewhere?
Through a range of original essays written by eminent ecologists and naturalists, The Ecology of Place explores how place-focused research yields exportable general knowledge as well as practical local knowledge, and how society can facilitate ecological understanding by investing in field sites, place-centered databases, interdisciplinary collaborations, and field-oriented education programs that emphasize natural history. This unique patchwork of case-study narratives, philosophical musings, and historical analyses is tied together with commentaries from editors Ian Billick and Mary Price that develop and synthesize common threads. The result is a unique volume rich with all-too-rare insights into how science is actually done, as told by scientists themselves.
This compelling odyssey of scientific discovery is also a frank account of fieldwork in a poverty-stricken, war-ravaged country. In her attempts to study an elephant community, O’Connell encounters corrupt government bureaucrats, deadly lions and rhinos, poachers, farmers fighting for arable land, and profoundly ineffective approaches to wildlife conservation. The Elephant’s Secret Sense is ultimately a story of intellectual courage in the face of seemingly insurmountable obstacles.
“I was transported by the author’s superbly sensuous descriptions of her years spent studying the animals. . . . Conjures a high-class nature documentary film in prose.”—Steven Poole, Guardian
“A ride as rough and astonishing as the roads of the African floodplain.”—Joan Keener, Entertainment Weekly
“A successful combination of science and soulfulness, explaining her groundbreaking theory of how elephants use seismic communication. . . . O’Connell’s account is studded with sympathetic insights and well-turned phrases.”—Publishers Weekly
“This fascinating book reads like a fast-paced detective story of a scientific discovery and adventure set in contemporary Africa. . . . By the end, O’Connell takes her rightful place among the leading biographers of the African elephant.”—Iain Douglas-Hamilton, author of Among the Elephants

Like nearly every area of scholarly inquiry today, the biological sciences are broken into increasingly narrow fields and subfields, its practitioners divided into ecologists, evolutionary biologists, taxonomists, paleontologists, and much more. But all these splintered pieces have their origins in the larger field of natural history—and in this era where climate change and relentless population growth are irrevocably altering the world around us, perhaps it’s time to step back and take a new, fresh look at the larger picture.
The Essential Naturalist offers exactly that: a wide-ranging, eclectic collection of writings from more than eight centuries of observations of the natural world, from Leeuwenhoek to E. O. Wilson, from von Humboldt to Rachel Carson. Featuring commentaries by practicing scientists that offer personal accounts of the importance of the long tradition of natural history writing to their current research, the volume serves simultaneously as an overview of the field’s long history and as an inspirational starting point for new explorations, for trained scientists and amateur enthusiasts alike.
According to polling data, most Americans doubt that evolution is a real phenomenon. And it’s no wonder that so many are skeptical: many of today’s biology courses and textbooks dwell on the mechanisms of evolution—natural selection, genetic drift, and gene flow—but say little about the evidence that evolution happens at all. How do we know that species change? Has there really been enough time for evolution to operate?
With The Evidence for Evolution, Alan R. Rogers provides an elegant, straightforward text that details the evidence for evolution. Rogers covers different levels of evolution, from within-species changes, which are much less challenging to see and believe, to much larger ones, say, from fish to amphibian, or from land mammal to whale. For each case, he supplies numerous lines of evidence to illustrate the changes, including fossils, DNA, and radioactive isotopes. His comprehensive treatment stresses recent advances in knowledge but also recounts the give and take between skeptical scientists who first asked “how can we be sure” and then marshaled scientific evidence to attain certainty. The Evidence for Evolution is a valuable addition to the literature on evolution and will be essential to introductory courses in the life sciences.
From the Scopes “Monkey Trial” of 1925 to the court ruling against the Dover Area School Board’s proposed intelligent design curriculum in 2005, few scientific topics have engendered as much controversy—or grabbed as many headlines—as evolution. And since the debate shows no signs of abating, there is perhaps no better time to step back and ask: What is evolution? Defined as the gradual process by which something changes into a different and usually more complex and efficient form, evolution explains the formation of the universe, the nature of viruses, and the emergence of humans. A first-rate summary of the actual science of evolution, this Scientific American reader is a timely collection that gives readers an opportunity to consider evolution’s impact in various settings.
Divided into four sections that consider the evolution of the universe, cells, dinosaurs, and humans, Evolution brings together more than thirty articles written by some of the world’s most respected evolutionary scientists. As tour guides through the genesis of the universe and complex cells, P. James E. Peebles examines the evidence in support of an expanding cosmos, while Christian de Duve discusses the birth of eukaryotes. In an article that anticipated his book Full House, Stephen Jay Gould argues that chance and contingency are as important as natural selection for evolutionary change. And Ian Tatersall makes two fascinating contributions, submitting his view that the schematic of human evolution looks less like a ladder and more like a bush.
With the latest on what’s being researched at every level of evolutionary studies, from prospects of life on other planets to the inner working of cells, Evolution offers general readers an opportunity to update their knowledge on this hot topic while giving students an introduction to the problems and methodologies of an entire field of inquiry.
Natural selection is one of the factors responsible for changes in biological populations. Some traits or organisms are fitter than others, and natural selection occurs when there are changes in the distribution of traits in populations because of fitness differences. Many philosophers of biology insist that a trait’s fitness should be defined as an average of the fitnesses of individual members of the population that have the trait.
Marshall Abrams argues convincingly against this widespread approach. As he shows, it conflicts with the roles that fitness is supposed to play in evolutionary theory and with the ways that evolutionary biologists use fitness concepts in empirical research. The assumption that a causal kind of fitness is fundamentally a property of actual individuals has resulted in unnecessary philosophical puzzles and years of debate. Abrams came to see that the fitnesses of traits that are the basis of natural selection cannot be defined in terms of the fitnesses of actual members of populations, as philosophers of biology often claim. Rather, it is an overall population-environment system—not actual, particular organisms living in particular environmental conditions—that is the basis of trait fitnesses. Abrams argues that by distinguishing different classes of fitness concepts and the roles they play in the practice of evolutionary biology, we can see that evolutionary biologists’ diverse uses of fitness concepts make sense together and are consistent with the idea that fitness differences cause evolution.
Abrams’s insight has broad significance, for it provides a general framework for thinking about the metaphysics of biological evolution and its relations to empirical research. As such, it is a game-changing book for philosophers of biology, biologists who want deeper insight into the nature of evolution, and anyone interested in the applied philosophy of probability.
"This book is unquestionably mandatory reading not only for every living biologist but for generations of biologists to come."—Jack P. Hailman, Animal Behaviour, review of the first edition
"An important contribution to modern evolutionary thinking. It fortifies the place of Evolutionary Theory among the other well-established natural laws."—R.Gessink,TAXON
Written by specialists in the field, the papers in this volume explore evolution of animals and plants on the deserts of North America, South America, and Australia. Together, the articles constitute a complete survey of the geological history of the deserts of three continents, the evolution of the animals and plants of those deserts, and their adaptations to the environments in which they live.
The first paper, by Otto T. Solbrig, discusses the flora of the South American temperate and semidesert regions, citing numerous genera and reasons that they are found in the different areas. John S. Beard uses the same approach in his discussion of the evolution of Australian desert plants and focuses on western Australian areas. Guillermo Sarmiento appraises the evolution of arid vegetation in tropical America, including the Lesser Antilles and the Coast Range of Venezuela and Colombia. A. R. Main surveys the adaptation of Australian vertebrates to desert conditions and gives examples of how various species of birds, reptiles, and amphibians adapt to their environment in order for the greatest number to survive. James A. MacMahon designates specific communities in the Mojave, Sonoran, and Chihuahuan deserts and discusses the similarity of species of the North American desert mammal faunas found there, while Bobbi S. Low focuses on the evolution of amphibian life histories in the desert and compiles a lengthy table of amphibia comparing egg size, habitat, number of eggs per clutch, and so forth. Finally, W. Frank Blair treats adaptation of anurans to equivalent desert scrub of North and South America and cites various species of frogs and toads that are found in similar areas.
The volume also includes an introduction by the editor and an index. Evolution of Desert Biota is the result of a symposium held during the First International Congress of Systematic and Evolutionary Biology in Boulder, Colorado; in August 1973.
Beginning with a general introduction to fossil Lagerstätten, Evolution of Fossil Ecosystems goes on, chapter by chapter, to consider each fossil site, detailing its evolutionary position and significance; a brief history of the locality; its background sedimentology, stratigraphy, and paleoenvironment; its biota and paleoecology; and its commonalities with similar Lagerstätten. Considering deposits both marine and terrestrial, the book covers one fossil site from the Precambrian era, five sites from the Paleozoic era, five sites from the Mesozoic era, and three sites from the Cenozoic era.
Illustrated with hundreds of color photographs and drawings, Evolution of Fossil Ecosystems is a sophisticated yet accessible guide to these critical sites. Containing useful appendixes listing important museums, instructions on how to visit the fossil sites, and additional suggested reading, this book will attract students, academics, and professionals in paleontology, evolution, and the earth and life sciences, as well as dedicated amateurs interested in fossils and geology.
At a time of unprecedented expansion in the life sciences, evolution is the one theory that transcends all of biology. Any observation of a living system must ultimately be interpreted in the context of its evolution. Evolutionary change is the consequence of mutation and natural selection, which are two concepts that can be described by mathematical equations. Evolutionary Dynamics is concerned with these equations of life. In this book, Martin A. Nowak draws on the languages of biology and mathematics to outline the mathematical principles according to which life evolves. His work introduces readers to the powerful yet simple laws that govern the evolution of living systems, no matter how complicated they might seem.
Evolution has become a mathematical theory, Nowak suggests, and any idea of an evolutionary process or mechanism should be studied in the context of the mathematical equations of evolutionary dynamics. His book presents a range of analytical tools that can be used to this end: fitness landscapes, mutation matrices, genomic sequence space, random drift, quasispecies, replicators, the Prisoner’s Dilemma, games in finite and infinite populations, evolutionary graph theory, games on grids, evolutionary kaleidoscopes, fractals, and spatial chaos. Nowak then shows how evolutionary dynamics applies to critical real-world problems, including the progression of viral diseases such as AIDS, the virulence of infectious agents, the unpredictable mutations that lead to cancer, the evolution of altruism, and even the evolution of human language. His book makes a clear and compelling case for understanding every living system—and everything that arises as a consequence of living systems—in terms of evolutionary dynamics.
Biology was forged into a single, coherent science only within living memory. In this volume the thinkers responsible for the “modern synthesis” of evolutionary biology and genetics come together to analyze that remarkable event.
In a new Preface, Ernst Mayr calls attention to the fact that scientists in different biological disciplines varied considerably in their degree of acceptance of Darwin’s theories. Mayr shows us that these differences were played out in four separate periods: 1859 to 1899, 1900 to 1915, 1916 to 1936, and 1937 to 1947. He thus enables us to understand fully why the synthesis was necessary and why Darwin’s original theory—that evolutionary change is due to the combination of variation and selection—is as solid at the end of the twentieth century as it was in 1859.
Explorations in Developmental Biology is a revolutionary departure from time-honored introductory texts. The book is based on the premise that the substance, concepts, and excitement of contemporary developmental biology are best communicated to students by using the same form in which they were first communicated to the scientific community — original research reports. But a simple collection of original papers is not sufficient; it is too limited in scope and too disjointed, and students are not prepared to read them with understanding. In this book, designed to serve as the principal text for a first or second course in developmental biology, basic concepts are presented in a series of 22 chapters that focus on major, often unsolved, problems ranging from self-assembly to embryonic induction to cellular communication by surface contact. Within each chapter the authors provide the necessary background in developmental biology, and also describe the specific experimental procedures that enable the student to understand and appreciate the contributions of significant research papers that are included. The authors' texts and the reprinted papers are integrated into a cohesive whole, so that each chapter provides up-to-date information about an important area of developmental biology and raises specific questions.
Throughout, the text is profusely illustrated with original drawings and with figures taken from the literature, and each chapter contains a brief guide to pertinent publications.
Explorations in Developmental Biology makes it possible for teachers and students to penetrate the perennial barrier between classroom and research laboratory. Students who use this book are well equipped to move on to more advanced studies in biology; for they will have acquired the ability to use and to evaluate original scientific communications and will have assimilated the subject matter of a science that is at the center of modern biology.
Reconstructing the avian world in the same way archeologists re-create ancient human societies, David Steadman—a leading authority on tropical Pacific avian paleontology—has spent the past two decades in the field, digging through layers of soil in search of the bones that serve as clues to the ancient past of island bird communities. His years of indefatigable research and analysis are the foundation for Extinction and Biogeography of Tropical Pacific Birds, a monumental study of the landbirds of tropical Pacific islands—especially those from Fiji eastward to Easter Island—and an intricate history of the patterns and processes of island biology over time.
Using information gleaned from prehistoric specimens, Steadman reconstructs the birdlife of tropical Pacific islands as it existed before the arrival of humans and in so doing corrects the assumption that small, remote islands were unable to support rich assemblages of plants and animals. Easter Island, for example, though devoid of wildlife today, was the world’s richest seabird habitat before Polynesians arrived more than a millennium ago. The forests of less isolated islands in the Pacific likewise teemed with megapodes, rails, pigeons, parrots, kingfishers, and songbirds at first human contact.
By synthesizing data from the distant past, Steadman hopes to inform present conservation programs. Grounded in geology, paleontology, and archeology, but biological at its core, Extinction and Biogeography of Tropical Pacific Birds is an exceptional work of unparalleled scholarship that will stimulate creative discussions of terrestrial life on oceanic islands for years to come.
