Balancing on the Brink of Extinction presents a comprehensive overview of the Endangered Species Act -- its conception, history, and potential for protecting the remaining endangered species.
In Banquet at Delmonico’s, Barry Werth draws readers inside the circle of intellectuals, scientists, politicians, businessmen, and clergymen who brought Charles Darwin’s controversial ideas to post-Civil-War America. Each chapter is dedicated to a crucial intellectual encounter, culminating with an exclusive farewell dinner held in English philosopher Herbert Spencer’s honor at the venerable New York restaurant Delmonico’s in 1882. In this thought-provoking and nuanced account, Werth firmly situates social Darwinism in the context of the Gilded Age. Banquet at Delmonico’s is social history at its finest.

Because they prey upon a wide variety of conifers, bark beetles have a major impact upon western forests. In most of the western states, for example, we have witnessed bark beetles in epidemic outbreaks, attacking and damaging ponderosa pine, limber pine, and other hosts.
The ecosystem of bark beetle and host tree is a highly coevolved community of organisms in which the evolution of one member of the community significantly influences the evolution of the other. Largely because of the enormous economic impact these insects exert on the management of our forests, few other such communities have been studied so extensively. Bark Beetles in North American Conifers brings together in one volume both theory and a wealth of empirical data gathered by researchers from all the fields in which bark beetles are studied: ecology, evolutionary biology, population genetics, entomology, and forestry.
Topics covered include the life cycle of bark beetles and their population dynamics, their genetic variation and evolutionary mechanisms, the evolution and systematics of the major groups of bark beetles, pheromone production and its implications for coevolution among these organisms, the interaction between bark beetles and their predators, host resistance and susceptibility, the relationship of parasites and symbiotic micro-organisms in general, and management and control of bark beetles based on sound ecological and evolutionary concepts. The concluding section of the book summarizes the dynamics of the coevolved system of bark beetle and host tree and discusses controversial issues for which this system may provide important answers.
Humans have lived in close proximity to other animals for thousands of years. Recent scientific studies have even shown that the presence of animals has a positive effect on our physical and mental health. People with pets typically have lower blood pressure, show fewer symptoms of depression, and tend to get more exercise.
But there is a darker side to the relationship between animals and humans. Animals are carriers of harmful infectious agents and the source of a myriad of human diseases. In recent years, the emergence of high-profile illnesses such as AIDS, SARS, West Nile virus, and bird flu has drawn much public attention, but as E. Fuller Torrey and Robert H. Yolken reveal, the transfer of deadly microbes from animals to humans is neither a new nor an easily avoided problem.
Beginning with the domestication of farm animals nearly 10,000 years ago, Beasts of the Earth traces the ways that human-animal contact has evolved over time. Today, shared living quarters, overlapping ecosystems, and experimental surgical practices where organs or tissues are transplanted from non-humans into humans continue to open new avenues for the transmission of infectious agents. Other changes in human behavior like increased air travel, automated food processing, and threats of bioterrorism are increasing the contagion factor by transporting microbes further distances and to larger populations in virtually no time at all.
While the authors urge that a better understanding of past diseases may help us lessen the severity of some illnesses, they also warn that, given our increasingly crowded planet, it is not a question of if but when and how often animal-transmitted diseases will pose serious challenges to human health in the future.
Selected from the country’s leading literary journals and publications—Colorado Review, Creative Nonfiction, Georgia Review, Prairie Schooner, Crazyhorse, The Normal School, and others—Beautiful Flesh gathers eighteen essays on the body, essentially building a multi-gender, multi-ethnic body out of essays, each concerning a different part of the body: belly, brain, bones, blood, ears, eyes, hair, hands, heart, lungs, nose, ovaries, pancreas, sinuses, skin, spine, teeth, and vas deferens. The title is drawn from Wendy Call’s essay “Beautiful Flesh,” a meditation on the pancreas: “gorgeously ugly, hideously beautiful: crimson globes embedded in a pinkish-tan oval, all nestled on a bed of cabbage-olive green, spun through with gossamer gold.”
Other essays include Dinty W. Moore’s “The Aquatic Ape,” in which the author explores the curious design and necessity of sinuses; Katherine E. Standefer’s “Shock to the Heart, Or: A Primer on the Practical Applications of Electricity,” a modular essay about the author’s internal cardiac defibrillator and the nature of electricity; Matt Roberts’s “Vasectomy Instruction 7,” in which the author considers the various reasons for and implications of surgically severing and sealing the vas deferens; and Peggy Shinner’s “Elective,” which examines the author’s own experience with rhinoplasty and cultural considerations of the “Jewish nose.” Echoing the myriad shapes, sizes, abilities, and types of the human body, these essays showcase the many forms of the genre: personal, memoir, lyric, braided, and so on.

Apes and dolphins: primates and cetaceans. Could any creatures appear to be more different? Yet both are large-brained intelligent mammals with complex communication and social interaction. In the first book to study apes and dolphins side by side, Maddalena Bearzi and Craig B. Stanford, a dolphin biologist and a primatologist who have spent their careers studying these animals in the wild, combine their insights with compelling results. Beautiful Minds explains how and why apes and dolphins are so distantly related yet so cognitively alike and what this teaches us about another large-brained mammal: Homo sapiens.
Noting that apes and dolphins have had no common ancestor in nearly 100 million years, Bearzi and Stanford describe the parallel evolution that gave rise to their intelligence. And they closely observe that intelligence in action, in the territorial grassland and rainforest communities of chimpanzees and other apes, and in groups of dolphins moving freely through open coastal waters. The authors detail their subjects’ ability to develop family bonds, form alliances, and care for their young. They offer an understanding of their culture, politics, social structure, personality, and capacity for emotion. The resulting dual portrait—with striking overlaps in behavior—is key to understanding the nature of “beautiful minds.”
Being among bees is a full-body experience, Mark Winston writes—from the low hum of tens of thousands of insects and the pungent smell of honey and beeswax, to the sight of workers flying back and forth between flowers and the hive. The experience of an apiary slows our sense of time, heightens our awareness, and inspires awe. Bee Time presents Winston’s reflections on three decades spent studying these creatures, and on the lessons they can teach about how humans might better interact with one another and the natural world.
Like us, honeybees represent a pinnacle of animal sociality. How they submerge individual needs into the colony collective provides a lens through which to ponder human societies. Winston explains how bees process information, structure work, and communicate, and examines how corporate boardrooms are using bee societies as a model to improve collaboration. He investigates how bees have altered our understanding of agricultural ecosystems and how urban planners are looking to bees in designing more nature-friendly cities.
The relationship between bees and people has not always been benign. Bee populations are diminishing due to human impact, and we cannot afford to ignore what the demise of bees tells us about our own tenuous affiliation with nature. Toxic interactions between pesticides and bee diseases have been particularly harmful, foreshadowing similar effects of pesticides on human health. There is much to learn from bees in how they respond to these challenges. In sustaining their societies, bees teach us ways to sustain our own.
In this book, W. John Smith enlarges ethology's perspective on communication and takes it in new directions. Traditionally, ethological analysis has focused on the motivational states of displaying animals: What makes the bird sing, the cat lash its tail, the bee dance? The Behavior of Communicating emphasizes messages. It seeks to answer questions about the information shared by animals through their displays: What information is made available to a bird by its neighbor's song, to a cat by its opponent's gesture, to a bee by its hivemate's dancing? What information is extracted from sources contextual to these displays? How are the responses to displays adaptive for recipients and senders? What evolutionary processes and constraints underlie observed patterns of animal communication?
Smith's approach is deeply rooted in the ethological tradition of naturalistic observations. Detailed analysis of observed displays and display repertoires illuminates the theoretical discussion that forms the core of the book. A taxonomy and interpretative analysis of messages made available through formalized display behavior are also developed. Smith shows that virtually all subhuman animal displays may be interpreted as transmitting messages about the communicator--not the environment--and, more specifically, that messages indicate the kinds of behavior the displaying animal may choose to perform. The most widespread behavioral messages are surprisingly general, even banal, in character; yet they make public information that is not readily available from other sources and that would otherwise be essentially private to the communicator. Taken along with information from sources contextual to the displays, the messages made available may permit responses that are markedly specific. By taking advantage of contextual specificity, a species expands the capacity of its display behavior to be functional in numerous and diverse circumstances.
After developing the concept of messages and discussing their forms, the responses made to them, and the functions engendered, Smith turns to the evolution of display behavior--the ways in which acts become specialized for communication and the nature of the evolutionary constraints affecting the ultimate forms of displays. He revises the traditional ethological concept of displays, and in a final chapter develops the further concept of formalized interactions. Here he extends the discussion to formal patterns of behavior that, unlike displays, are beyond the capabilities of individual performers. Human nonverbal communication, which is considered from time to time throughout the book, provides the richest examples of communication flexibly structured at this level of complexity.
This readable text represents a much needed synthesis of ecological insight into animal behavior. The field of behavioral ecology is relatively new, having evolved from a combination of classical ethology, as developed by Lorenz and Tinbergen, and population ecology. Now for the first time, a single author integrates the vast literature on animal ecology and behavior into a conceptual whole.
Exploring the theme of resource acquisitions, Douglass H. Morse combines the comparative approach to biology with models based on evolutionary theory. Secondary consequences of sexual selection and other selective pressures are considered in detail. Discussion of interspecific interactions and constraints is especially rich, as is the treatment of foraging theory, kinship theory, habitat selection and predator avoidance. Perhaps the book’s greatest achievement, however, is its unparalleled ecological and evolutionary analysis of individual differences.
Behavioral Mechanisms in Ecology will meet the teaching and reference needs of an extremely broad audience of professional biologists.
Gaylord Nelson’s legacy is known and respected throughout the world. He was a founding father of the modern environmental movement and creator of one of the most influential public awareness campaigns ever undertaken on behalf of global environmental stewardship: Earth Day.
Nelson died in 2005, but his message in this book is still timely and urgent, delivered with the same eloquence with which he articulated the nation’s environmental ills throughout the decades. He details the planet’s most critical concerns—from species and habitat losses to global climate change and population growth. In outlining strategies for planetary health, Nelson inspires citizens to reassert environmentalism as a national priority. Included in this reprint is a new preface by Gaylord Nelson’s daughter, Tia Nelson.
Beyond Preservation was first published in 1993. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
Addressing current ecological issues, from the philosophical to the practical, Frederick Turner and William R. Jordan III Here offer a new paradigm for understanding the relationship between the humans and nature. Challenging the idea that preserving nature is the only solution to environmental problems, they advocate going beyond preservation to restoration and actual construction of our landscape. Fifteen respondents reflect on the implications and consequences of Turner’s and Jordan’s bold proposals.“Ecological restoration is the most helpful and provocative contribution to our thinking about nature to come along in many years, and Beyond Preservation is without a doubt the best book on the subject to date.” Michael Polan, Harper’sContributors include Gary W. Barrett, Ann Cline, David L. Gorchov, William Jordan III, G. Stanley Kane, Jack Temple Kirby, Dora G. Lodwick, Orie L. Loucks, Kimberly E. Medley, Constance Pierce, Ellen Price, Frederick Turner, John E. Wierwille, and Gene E. Willeke.In his latest book, David Bainbridge combines an otherworldly journey through the central nervous system with an accessible and entertaining account of how the brain's anatomy has often misled anatomists about its function. Bainbridge uses the structure of the brain to set his book apart from the many volumes that focus on brain function. He shows that for hundreds of years, natural philosophers have been interested in the gray matter inside our skulls, but all they had to go on was its structure. Almost every knob, protrusion, canal, and crease was named before anyone had an inkling of what it did--a kind of biological terra incognita with many weird and wonderful names: the zonules of Zinn, the obex ("the most Scrabble-friendly word in all of neuroanatomy"), the aqueduct of Sylvius, the tract of Goll.
This uniquely accessible approach lays out what is known about the brain (its structure), what we can hope to know (its function), and what we may never know (its evolution). Along the way Bainbridge tells lots of wonderful stories about the "two pounds of blancmange" within our skulls, and tells them all with wit and style.
Biohackers explores fundamental changes occuring in the circulation and ownership of scientific information. Alessandro Delfanti argues that the combination of the ethos of 20th century science, the hacker movement and the free software movement is producing an open science culture which redefines the relationship between researchers, scientific institutions and commercial companies.
Biohackers looks at the emergence of the citizen biology community ‘DIYbio’, the shift to open access by the American biologist Craig Venter and the rebellion of the Italian virologist Ilaria Capua against WHO data-sharing policies.
Delfanti argues that these biologists and many others are involved in a transformation of both life sciences and information systems, using open access tools and claiming independence from both academic and corporate institutions.
Robotic exoskeletons that allow stroke survivors to regain use of their limbs, 3D-printed replacement body parts, and dozens of other innovations still in schematic design are revolutionizing the treatment of debilitating injuries and nervous system disorders. What all these technologies have in common is that they are modeled after engineering strategies found in nature—strategies developed by a vast array of organisms over eons of evolutionary trial and error.
Eugene Goldfield lays out many principles of engineering found in the natural world, with a focus on how evolutionary and developmental adaptations, such as sensory organs and spinal cords, function within complex organisms. He shows how the component parts of highly coordinated structures organize themselves into autonomous functional systems. For example, when people walk, spinal cord neurons generate coordinated signals that continuously reorganize patterns of muscle activations during the gait cycle. This self-organizing capacity is just one of many qualities that allow biological systems to be robust, adaptive, anticipatory, and self-repairing. To exploit the full potential of technologies designed to interact seamlessly with human bodies, properties like these must be better understood and harnessed at every level, from molecules to cells to organ systems.
Bioinspired Devices brings together insights from a wide range of fields. A member of the Wyss Institute for Biologically Inspired Engineering, Goldfield offers an insider’s view of cutting-edge research, and envisions a future in which synthetic and biological devices share energy sources and control, blurring the boundary between nature and medicine.
At the 1988 summer session, the internationally famous Marine Biological Laboratory (MBL) at Woods Hole, Massachusetts celebrated one hundred years of pioneering science. During the centennial festivities, many of the world's most renowned biologists assembled at MBL and delivered the Lab's traditional Friday Night Lectures, which as always were extraordinary and memorable. These lectures have been gathered and judiciously edited here by three eminent participants.
Each centennial lecture is dedicated to one or two MBL pioneers, investigators at the forefront of the "new biology" that emerged toward the turn of the century. The MBL often provided an environment that was conducive to revolutionizing the discipline, replacing its largely descriptive and speculative methods with lively analytical and experimental science.
Combining history and current science, each lecture focuses on a subfield of biology. The speakers represented include John Gurdon on developmental biology, Joshua Lederberg on genetics, Torsten Wiesel on neurobiology, and E. 0. Wilson on animal behavior. Benjamin Kamminer provides an account of the work of Albert Szent-Györgyi, capturing his iconoclastic, tenacious, sometimes outrageous nature, as well as his humor and insight. And Gerald Weissmann compares Jacques Loeb and Gertrude Stein--an unlikely pair bound by their common assent to mechanistic materialism.
The history and scientific discovery in these pages should convey for any reader whether biologist, historian, or interested layperson--the excitement of the renowned laboratory and the drama and frustration of biology in the twentieth century.
Over the course of human history, the sciences, and biology in particular, have often been manipulated to cause immense human suffering. For example, biology has been used to justify eugenic programs, forced sterilization, human experimentation, and death camps—all in an attempt to support notions of racial superiority. By investigating the past, the contributors to Biology and Ideology from Descartes to Dawkins hope to better prepare us to discern ideological abuse of science when it occurs in the future.
Denis R. Alexander and Ronald L. Numbers bring together fourteen experts to examine the varied ways science has been used and abused for nonscientific purposes from the fifteenth century to the present day. Featuring an essay on eugenics from Edward J. Larson and an examination of the progress of evolution by Michael J. Ruse, Biology and Ideology examines uses both benign and sinister, ultimately reminding us that ideological extrapolation continues today. An accessible survey, this collection will enlighten historians of science, their students, practicing scientists, and anyone interested in the relationship between science and culture.
Technology is a process and a body of knowledge as much as a collection of artifacts. Biology is no different—and we are just beginning to comprehend the challenges inherent in the next stage of biology as a human technology. It is this critical moment, with its wide-ranging implications, that Robert Carlson considers in Biology Is Technology. He offers a uniquely informed perspective on the endeavors that contribute to current progress in this area—the science of biological systems and the technology used to manipulate them.
In a number of case studies, Carlson demonstrates that the development of new mathematical, computational, and laboratory tools will facilitate the engineering of biological artifacts—up to and including organisms and ecosystems. Exploring how this will happen, with reference to past technological advances, he explains how objects are constructed virtually, tested using sophisticated mathematical models, and finally constructed in the real world.
Such rapid increases in the power, availability, and application of biotechnology raise obvious questions about who gets to use it, and to what end. Carlson’s thoughtful analysis offers rare insight into our choices about how to develop biological technologies and how these choices will determine the pace and effectiveness of innovation as a public good.
This synthesis of thirty-five years of intensive investigation comes at a particularly propitious moment. Since the Second World War, cell biology and molecular biology have worked separately in probing the central question of cancer research--how do cells divide?--biology focusing on cell behavior in isolation and as part of tissues and organs, molecular biology concentrating on individual biochemical steps, especially as controlled by genes. But now a new alliance is being forged in the continuing effort to conquer cancer. New discoveries point to the value of an interdisciplinary approach, and for the first time scientists from both camps are struggling to catch up on one another's literature.
Baserga's work provides the unifying background for this cross-fertilization of ideas. It begins with the growth of cell populations and how cells interact with each other. The second section goes within the cell to consider the effect of drugs, the use of temperature-sensitive mutants of the cell cycle, and the use of cell fusion to understand how cells divide. The third section turns to the molecular genetics of cell proliferation, the growth factors, and the genes and gene products that regulate cell division.
Drawing on more than five hundred classic and recent references, the book is comprehensive yet refreshingly readable. It will provide a congenial and sophisticated introduction for students as well as working scientists.
The Biology of Human Starvation was first published in 1950. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions.
With great areas of the world battling the persistent and basic problem of hunger, this work constitutes a major contribution to needed scientific knowledge. The publication is a definitive treatise on the morphology, biochemistry, physcology, psychology, and medical aspects of calorie undernutrition, cachexia, starvation, and rehabilitation in man.
Presented critically and systematically are the fact and theory from the world literature, including the evidence from World War II and the finding of the Minnesota Starvation Experiment (1944*1946). Pertinent experiments and field and clinical observations to 1949 are covered.
The extensive original research involved was conducted at the University of Minnesota Laboratory of Physiological Hygiene, which Dr. Keys heads. The authors, all of the laboratory staff, were assisted in preparation of the work by Ernst Simonson, Samuel Wells and Angie Sturgeon Skinner.
From ancient cave paintings of honey bee nests to modern science’s richly diversified investigation of honey bee biology and its applications, the human imagination has long been captivated by the mysterious and highly sophisticated behavior of this paragon among insect societies. In the first broad treatment of honey bee biology to appear in decades, Mark Winston provides rare access to the world of this extraordinary insect.
In a bright and engaging style, Winston probes the dynamics of the honey bee’s social organization. He recreates for us the complex infrastructure of the nest, describes the highly specialized behavior of workers, queens, and drones, and examines in detail the remarkable ability of the honey bee colony to regulate its functions according to events within and outside the nest. Winston integrates into his discussion the results of recent studies, bringing into sharp focus topics of current bee research. These include the exquisite architecture of the nest and its relation to bee physiology; the intricate division of labor and the relevance of a temporal caste structure to efficient functioning of the colony; and, finally, the life-death struggles of swarming, supersedure, and mating that mark the reproductive cycle of the honey bee.
The Biology of the Honey Bee not only reviews the basic aspects of social behavior, ecology, anatomy, physiology, and genetics, it also summarizes major controversies in contemporary honey bee research, such as the importance of kin recognition in the evolution of social behavior and the role of the well-known dance language in honey bee communication. Thorough, well-illustrated, and lucidly written, this book will for many years be a valuable resource for scholars, students, and beekeepers alike.
Life on earth is characterized by three striking phenomena that demand explanation: adaptation—the marvelous fit between organism and environment; diversity—the great variety of organisms; and complexity—the enormous intricacy of their internal structure. Natural selection explains adaptation. But what explains diversity and complexity? Daniel W. McShea and Robert N. Brandon argue that there exists in evolution a spontaneous tendency toward increased diversity and complexity, one that acts whether natural selection is present or not. They call this tendency a biological law—the Zero-Force Evolutionary Law, or ZFEL. This law unifies the principles and data of biology under a single framework and invites a reconceptualization of the field of the same sort that Newton’s First Law brought to physics.
Biology’s First Law shows how the ZFEL can be applied to the study of diversity and complexity and examines its wider implications for biology. Intended for evolutionary biologists, paleontologists, and other scientists studying complex systems, and written in a concise and engaging format that speaks to students and interdisciplinary practitioners alike, this book will also find an appreciative audience in the philosophy of science.
Bioluminescence is everywhere on earth—most of all in the ocean, from angler fish in the depths to the flashing of dinoflagellates at the surface. Here, Thérèse Wilson and Woody Hastings explore the natural history, evolution, and biochemistry of the diverse array of organisms that emit light.
While some bacteria, mushrooms, and invertebrates, as well as fish, are bioluminescent, other vertebrates and plants are not. The sporadic distribution and paucity of luminous forms calls for explanation, as does the fact that unrelated groups evolved completely different biochemical pathways to luminescence. The authors explore the hypothesis that many different luciferase systems arose in the early evolution of life because of their ability to remove oxygen, which was toxic to life when it first appeared on earth. As oxygen became abundant and bioluminescence was no longer adequate for oxygen removal, other antioxidant mechanisms evolved and most luminous species became extinct. Those light-emitting species that avoided extinction evolved uses with survival value for the light itself. Today’s luminous organisms use bioluminescence for defense from predators, for their own predatory purposes, or for communication in sexual courtship.
Bioluminescence was earlier viewed as a fascinating feature of the living world, but one whose study seemed unlikely to contribute in any practical way. Today, bioluminescence is no longer an esoteric area of research. Applications are numerous, ranging from the rapid detection of microbial contamination in beef and water, to finding the location of cancer cells, to working out circuitry in the brain.
In diverse regions around the country, impending crises over dwindling natural resources and conflicts over land use have given birth to a new approach to environmental management and policymaking. Known as bioregional assessment, the approach gives science and scientists a crucial role in the policymaking process, bringing together experts on a range of issues to assess existing ecological and social conditions and to provide a base of knowledge from which to develop policy options and management decisions.
A number of high-profile assessments have been conducted, and while much has been written on individual projects, little has been done to compare assessments or integrate the lessons they provide. Bioregional Assessments synthesizes the knowledge from many regions by examining the assessment process and detailing a series of case studies from around the country. Each case study, written by knowledgeable leaders from the region, features a detailed description of the project followed by reviews from the perspectives of science, management, and policy.
Case studies examined are the Forest Ecosystem Management Assess ment Team (FEMAT) Assessment; the Great Lakes-St. Lawrence River Basin Assessments; the Everglades-South Florida Assessments; the Northern Forest Lands Assessments; Southern California Natural Community Conservation Planning (NCCP); the Interior Columbia Basin Ecosystem Management Project; and the Sierra Nevada Ecosystem Project.
In addition, the book features introductory chapters that examine the challenges inherent in the assessment of complex regional systems, and the role of science in the assessment process. The concluding chapter provides a synthesis and analysis of the assessment process.
Bioregional assessments are quickly becoming an essential part of ecosystem management. This book provides a unique look at the theory and practice of bioregional assessments, and is an essential volume for resource managers, scientists, policymakers, and anyone involved with formulating or implementing strategies for regional planning and ecosystem management.
One cannot help being struck with wonder at the vivid pink of 10,000 flamingos rising from Lake Nakuru or the glowing red gorget of a ruby-throated hummingbird feeding outside the kitchen window. How birds produce the brilliant and striking coloration of their feathers and other body parts is the focus of this first volume of Bird Coloration. It has been more than 40 years since the mechanisms of color production of birds have been reviewed and synthesized and in those 40 years new pigments have been discovered, new genetic mechanisms have been described, new theories have been developed, and hundreds of new experiments have been conducted.
Geoffrey Hill and Kevin McGraw have assembled the world’s leading experts in perception, measurement, and control of bird coloration to contribute to this book. This sumptuously illustrated volume synthesizes more than 1,500 technical papers in this field. The focus is on the three primary mechanisms of color production—melanin pigmentation, carotenoid pigmentation, and structural coloration—but less common as well as newly described mechanisms of color production are also reviewed in detail. The visual perception of birds and the best ways to collect and analyze color data are, for the first time, presented as part of the review of mechanisms of coloration. This book will be essential reading for biologists studying animal coloration, but it will also be treasured by anyone curious about how birds produce and perceive their bold and brilliant color displays.
In this companion volume to Bird Coloration, Volume 1: Mechanisms and Measurements, Geoffrey E. Hill and Kevin J. McGraw have assembled some of the world’s leading experts in the function and evolution of bird coloration to contribute to a long-overdue synthesis of a burgeoning field of inquiry. In Volume 2, the authors turn from the problem of how birds see and produce color, and how researchers measure it, to the function of the colorful displays of birds and the factors that shape the evolution of color signals.
The contributors to this volume begin by examining the function of coloration in a variety of contexts from mate choice, to social signaling, to individual recognition, synthesizing a vast amount of recent findings by researchers around the world. The volume and the series conclude with chapters that consider coloration from an explicitly evolutionary perspective, examining selective pressures that have led to the evolution of colors and patterns on body and plumage. These functional and evolutionary studies build from research on mechanisms of production and controls of expression, covered in the previous volume, bringing the study of color full circle.
This sumptuously illustrated book will be essential reading for biologists studying animal coloration, but it will also be treasured by anyone curious about why birds are colorful and how they got that way.
From the tufted puffin in the Pacific Northwest to the hook-billed hermit in the Brazilian rainforest, birds suffer from the effects of climate change in every corner of the globe. Scientists have found declines of up to 90 percent in some troubled bird populations and unprecedented reproductive failure in others. The most recent studies suggest dire prospects: 1,227 avian species are threatened with extinction and an additional 838 near-threatened species are urgent priorities for conservation action.
As much an indispensable guide as a timely call to action, Bird Watch is an illustrated tour of these endangered birds and their habitats. Encyclopedic in scope, this book features all 1,227 species on the International Union for Conservation of Nature (IUCN) Red List, thoroughly detailing the environmental pressures and conservation prescriptions that hold their futures in the balance. After introducing readers to the main threats to birds and regions at high risk, Bird Watch presents a visually stunning and scientifically accurate flight over the major bird habitats, including tropical forests; temperate and northern forests; deserts; mountains; grasslands; and Mediterranean, marine, freshwater, and oceanic islands. The volume concludes with an overview of bird species by region—categorized by family within each region, and a guide to the world’s best birding sites. Produced in cooperation with BirdLife International, Bird Watch is a celebration of the beauty and diversity of birds and their habitats—and a warning of the dangers they face around the world.
In this masterful account, a historian of science surveys the molecular biology revolution, its origin and continuing impact.
Since the 1930s, a molecular vision has been transforming biology. Michel Morange provides an incisive and overarching history of this transformation, from the early attempts to explain organisms by the structure of their chemical components, to the birth and consolidation of genetics, to the latest technologies and discoveries enabled by the new science of life. Morange revisits A History of Molecular Biology and offers new insights from the past twenty years into his analysis.
The Black Box of Biology shows that what led to the incredible transformation of biology was not a simple accumulation of new results, but the molecularization of a large part of biology. In fact, Morange argues, the greatest biological achievements of the past few decades should still be understood within the molecular paradigm. What has happened is not the displacement of molecular biology by other techniques and avenues of research, but rather the fusion of molecular principles and concepts with those of other disciplines, including genetics, physics, structural chemistry, and computational biology. This has produced decisive changes, including the discoveries of regulatory RNAs, the development of massive scientific programs such as human genome sequencing, and the emergence of synthetic biology, systems biology, and epigenetics.
Original, persuasive, and breathtaking in its scope, The Black Box of Biology sets a new standard for the history of the ongoing molecular revolution.
The major goal of developmental neurobiology is to understand how the nervous system is put together. A central theme that has emerged from research in this field over the last several decades is the crucial role of trophic interactions in neural assembly, and indeed throughout an animal's life. Trophic—which means nutritive—refers to long-term interdependencies between nerve cells and the cells they innervate.
The theory of trophic effects presented in this book offers an explanation of how the vertebrate nervous system is related to—and regulated by—the body it serves. The theory rationalizes the nervous system's accommodation, throughout life, to the changing size and form of the body it tenants, indicating the way connections between nerve cells change in response to stimuli as diverse as growth, injury, experience, and natural selection.
Dale Purves, a leading neurobiologist best known for his work on the formation and maintenance of synaptic connections, presents this theory within the historical setting of earlier ideas about neural organization—from Weiss's theory of functional reorganization to the chemoaffinity theory championed by Sperry. In addition to illuminating eighty years of work on trophic interactions, this book asks its own compelling questions: Are trophic interactions characteristic of all animals or only of those with complex nervous systems? Are trophic interactions related to learning? What does the trophic theory of neural connections imply about the currently fashionable view that the nervous system operates according to Darwinian principles?
Purves lays the theoretical foundation for practical exploration of trophic interactions as they apply to neural connections, a pursuit that will help us understand how our own nervous systems generate change. The ideas in this book not only enrich neurobiology but also convey the profound relevance of neuroscience to other fields of life science.
Whether you're a polar bear giving birth to cubs in an Arctic winter, a camel going days without water in the desert heat, or merely a suburbanite without air conditioning in a heat wave, your comfort and even survival depend on how well you adapt to extreme temperatures.
In this entertaining and illuminating book, biopsychologist Mark Blumberg explores the many ways that temperature rules the lives of all animals (including us). He moves from the physical principles that govern the flow of heat in and out of our bodies to the many complex evolutionary devices animals use to exploit those principles for their own benefit.
In the process Blumberg tells wonderful stories of evolutionary and scientific ingenuity--how penguins withstand Antarctic winters by huddling together by the thousands, how vulnerable embryos of many species are to extremes of temperature during their development, why people survive hour-long drowning accidents in winter but not in summer, how certain plants generate heat (the skunk cabbage enough to melt snow around it). We also hear of systems gone awry--how desert species given too much water can drink themselves into bloated immobility, why anorexics often complain of feeling cold, and why you can't sleep if the room is too hot or too cold. After reading this book, you'll never look at a thermostat in quite the same way again.
Whether classified as regulators of inflammation, metabolism, or other physiological functions, a distinctive set of molecules enables the human body to convey information from one cell to another. An in-depth primer on the molecular mediators that coordinate complex bodily processes, Body Messages provides fresh insight into how biologists first identified this special class of molecules and the consequences of their discovery for modern medicine.
Focusing on proteins that regulate inflammation and metabolism—including the cytokines and adipokines at the core of her own research—Giamila Fantuzzi examines the role body messages play in the physiology of health as well as in the pathology of various illnesses. Readers are introduced to different ways of conceptualizing biomedical research and to the advantages and pitfalls associated with identifying molecules beginning with function or structure. By bringing together areas of research usually studied separately, Fantuzzi stresses the importance of investigating the body as a whole and affirms the futility of trying to separate basic from clinical research. Drawing on firsthand interviews with researchers who made major contributions to the field, Body Messages illustrates that the paths leading to scientific discovery are rarely direct, nor are they always the only routes available.
As explorers and scientists have known for decades, the Neotropics harbor a fantastic array of our planet’s mammalian diversity, from capybaras and capuchins to maned wolves and mouse opossums to sloths and sakis. This biological bounty can be attributed partly to the striking diversity of Neotropical landscapes and climates and partly to a series of continental connections that permitted intermittent faunal exchanges with Africa, Antarctica, Australia, and North America. Thus, to comprehend the development of modern Neotropical mammal faunas requires not only mastery of the Neotropics’ substantial diversity, but also knowledge of mammalian lineages and landscapes dating back to the Mesozoic.
Bones, Clones, and Biomes offers just that—an exploration of the development and relationships of the modern mammal fauna through a series of studies that encompass the last 100 million years and both Central and South America. This work serves as a complement to more taxonomically driven works, providing for readers the long geologic and biogeographic contexts that undergird the abundance and diversity of Neotropical mammals. Rather than documenting diversity or distribution, this collection traverses the patterns that the distributions and relationships across mammal species convey, bringing together for the first time geology, paleobiology, systematics, mammalogy, and biogeography. Of critical importance is the book’s utility for current conservation and management programs, part of a rapidly rising conservation paleobiology initiative.
Colorful, mysterious, and often fantastically shaped, fungi have been a source of wonder and fascination since the earliest hunter-gatherers first foraged for them. Today there are few, if any, places on Earth where fungi have not found themselves a home. And these highly specialized organisms are an indispensable part of the great chain of life. They not only partner in symbiotic relationships with over ninety percent of the world’s trees and flowering plant species, they also recycle and create humus, the fertile soil from which such flora receive their nutrition. Some fungi are parasites or saprotrophs; many are poisonous and, yes, hallucinogenic; others possess life-enhancing properties that can be tapped for pharmaceutical products; while a delicious few are prized by epicureans and gourmands worldwide.
In this lavishly illustrated volume, six hundred fungi from around the globe get their full due. Each species here is reproduced at its actual size, in full color, and is accompanied by a scientific explanation of its distribution, habitat, association, abundance, growth form, spore color, and edibility. Location maps give at-a-glance indications of each species’ known global distribution, and specially commissioned engravings show different fruitbody forms and provide the vital statistics of height and diameter. With information on the characteristics, distinguishing features, and occasionally bizarre habits of these fungi, readers will find in this book the common and the conspicuous, the unfamiliar and the odd. There is a fungal predator, for instance, that hunts its prey with lassos, and several that set traps, including one that entices sows by releasing the pheromones of a wild boar.
Mushrooms, morels, puffballs, toadstools, truffles, chanterelles—fungi from habitats spanning the poles and the tropics, from the highest mountains to our own backyards—are all on display in this definitive work.
