Thus, the literature on speciation, as well as the number of researchers and students working in this area, has grown explosively. Despite thesedevelopments, there has been no book-length treatment of speciation in many years. As a result, both the seasoned scholar and the newcomer to evolutionary biology had no ready guide to the recent literature on speciation--a body of work that is enormous, scattered, and increasingly technical.Although several excellent symposium volumes have recently appeared, these collections do not provide a unified, critical, and up-to-date overview of the field. Speciation is designed to fill this gap.Aimed at professional biologists, graduate students, and advanced undergraduates, Speciation covers both plants and animals (the first book on this subject to do so), and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecularstudies. It gives special emphasis to topics that are either controversial or the subject of active research, including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural andsexual selection in the origin of species. The authors do not hesitate to take stands on these and other controversial issues. This critical and scholarly book will be invaluable to researchers in evolutionary biology and is also ideal for a graduate-level course on speciation.

    Molecular Cell Biology stands out from its peers in this course in that it provides a clear introduction to the techniques and experiments of scientists past and present, not just an "encyclopedia" of information.  This experimental emphasis, together with a solid pedagogical framework in the chapters, provides the clearest, most cutting-edge text available.

    Its presence in nature was dismissed as a desperate response to starvation or other life-threatening circumstances, and few spent time studying it. A taboo subject in our culture, the behavior was portrayed mostly through horror movies or tabloids sensationalizing the crimes of real-life flesh-eaters. But the true nature of cannibalism--the role it plays in evolution as well as human history--is even more intriguing (and more normal) than the misconceptions we've come to accept as fact. In Cannibalism: A Perfectly Natural History, zoologist Bill Schutt sets the record straight, debunking common myths and investigating our new understanding of cannibalism's role in biology, anthropology, and history in the most fascinating account yet written on this complex topic. Schutt takes readers from Arizona's Chiricahua Mountains, where he wades through ponds full of tadpoles devouring their siblings, to the Sierra Nevadas, where he joins researchers who are shedding new light on what happened to the Donner Party--the most infamous episode of cannibalism in American history. He even meets with an expert on the preparation and consumption of human placenta (and, yes, it goes well with Chianti). Bringing together the latest cutting-edge science, Schutt answers questions such as why some amphibians consume their mother's skin; why certain insects bite the heads off their partners after sex; why, up until the end of the twentieth century, Europeans regularly ate human body parts as medical curatives; and how cannibalism might be linked to the extinction of the Neanderthals. He takes us into the future as well, investigating whether, as climate change causes famine, disease, and overcrowding, we may see more outbreaks of cannibalism in many more species--including our own.Cannibalism places a perfectly natural occurrence into a vital new context and invites us to explore why it both enthralls and repels us.

    Because of this balance, "Microbiology" is appropriate for microbiology majors and mixed majors courses. The new authors have focused on readability, artwork, and the integration of several key themes (including evolution, ecology and diversity) throughout the text, making an already superior text even better.

    Finding this natural basis of life has proved elusive, but in the eloquent and creative Into the Cool, Eric D. Schneider and Dorion Sagan look for answers in a surprising place: the second law of thermodynamics. This second law refers to energy's inevitable tendency to change from being concentrated in one place to becoming spread out over time. In this scientific tour de force, Schneider and Sagan show how the second law is behind evolution, ecology,economics, and even life's origin.Working from the precept that "nature abhors a gradient," Into the Cool details how complex systems emerge, enlarge, and reproduce in a world tending toward disorder. From hurricanes here to life on other worlds, from human evolution to the systems humans have created, this pervasive pull toward equilibrium governs life at its molecular base and at its peak in the elaborate structures of living complex systems. Schneider and Sagan organize their argument in a highly accessible manner, moving from descriptions of the basic physics behind energy flow to the organization of complex systems to the role of energy in life to the final section, which applies their concept of energy flow to politics, economics, and even human health.A book that needs to be grappled with by all those who wonder at the organizing principles of existence, Into the Cool will appeal to both humanists and scientists. If Charles Darwin shook the world by showing the common ancestry of all life, so Into the Cool has a similar power to disturb—and delight—by showing the common roots in energy flow of all complex, organized, and naturally functioning systems.“Whether one is considering the difference between heat and cold or between inflated prices and market values, Schneider and Sagan argue, we can apply insights from thermodynamics and entropy to understand how systems tend toward equilibrium. The result is an impressive work that ranges across disciplinary boundaries and draws from disparate literatures without blinking.”—Publishers Weekly

    But evolutionary biologists also point out many examples of contingency, cases where the tiniest change--a random mutation or an ancient butterfly sneeze--caused evolution to take a completely different course. What role does each force really play in the constantly changing natural world? Are the plants and animals that exist today, and we humans ourselves, inevitabilities or evolutionary freaks? And what does that say about life on other planets?Jonathan Losos reveals what the latest breakthroughs in evolutionary biology can tell us about one of the greatest ongoing debates in science. He takes us around the globe to meet the researchers who are solving the deepest mysteries of life on Earth through their work in experimental evolutionary science. Losos himself is one of the leaders in this exciting new field, and he illustrates how experiments with guppies, fruit flies, bacteria, foxes, and field mice, along with his own work with anole lizards on Caribbean islands, are rewinding the tape of life to reveal just how rapid and predictable evolution can be.Improbable Destinies will change the way we think and talk about evolution. Losos's insights into natural selection and evolutionary change have far-reaching applications for protecting ecosystems, securing our food supply, and fighting off harmful viruses and bacteria. This compelling narrative offers a new understanding of ourselves and our role in the natural world and the cosmos.

    As our prehistoric ancestors spread throughout the globe, they began the most deadly epoch the planet's fauna have experienced since the demise of the dinosaurs. And following the dawn of the age of exploration five hundred years ago, the rate of extinction has accelerated ever more rapidly." In A Gap in Nature, scientist and historian Tim Flannery, in collaboration with internationally acclaimed wildlife artist Peter Schouten, catalogues 103 creatures that have vanished from the face of the earth since Columbus first set foot in the New World. From the colorful Carolina parakeet to the gigantic Steller's sea cow, Flannery evocatively tells the story of each animal and its habitat, how it lived and how it succumbed to its terrible destiny. Accompanying every entry is a beautifully rendered color representation by Schouten, who has devoted years of his life to this project. His portraits - life size in their original form - are exquisitely reproduced in this extraordinary book and include animals from every continent: American passenger pigeons, Tasmanian thylacines, Mauritian dodos, African bluebucks, and dozens more.

    From the Himalayan slopes of Bhutan to the most isolated mountain ranges of New Guinea, The Kingdom of Rarities takes us to some of the least-traveled places on the planet to catch a glimpse of these unique animals and many others. As he shares stories of these species, Eric Dinerstein gives readers a deep appreciation of their ecological importance and the urgency of protecting all types of life—the uncommon and abundant alike.An eye-opening tour of the rare and exotic, The Kingdom of Rarities offers us a new understanding of the natural world, one that places rarity at the center of conservation biology. Looking at real-time threats to biodiversity, from climate change to habitat fragmentation, and drawing on his long and distinguished scientific career, Dinerstein offers readers fresh insights into fascinating questions about the science of rarity and unforgettable experiences from the field.

    A group of young scientists, under the guidance of Dr. George Church, the most brilliant geneticist of our time, works to make fantasy reality by sequencing the DNA of a frozen woolly mammoth harvested from above the Arctic circle, and splicing elements of that sequence into the DNA of a modern elephant. Will they be able to turn the hybrid cells into a functional embryo and bring the extinct creatures to life in our modern world?Along with Church and his team of Harvard scientists, a world-famous conservationist and a genius Russian scientist plan to turn a tract of the Siberian tundra into Pleistocene Park, populating the permafrost with ancient herbivores as a hedge against an environmental ticking time bomb.

    Its signature outline format, full-color illustrations, and end-of-chapter summaries and USMLE-style review questions make it one of the most user-friendly books in the field. New features include boxed, high-yield facts throughout each chapter and expanded coverage of molecular biology.A companion Website features fully searchable online text and additional USMLE-style questions for students and an Image Bank for faculty.

    No one can stop him--but he walks away. A miracle? No...dysentery. Microbes saved the Roman Empire. Nearly a millennium later, the microbes of the Black Death ended the Middle Ages, making possible the Renaissance, western democracy, and the scientific revolution. Soon after, microbes ravaged the Americas, paving the way for their European conquest. Again and again, microbes have shaped our health, our genetics, our history, our culture, our politics, even our religion and ethics. This book reveals much that scientists and cultural historians have learned about the pervasive interconnections between infectious microbes and humans. It also considers what our ongoing fundamental relationship with infectious microbes might mean for the future of the human species. The "good side" of history's worst epidemics The surprising debt we owe to killer diseases Where diseases came from... ...and where they may be going Children of pestilence: disease and civilization From Egypt to Mexico, the Romans to Attila the Hun STDs, sexual behavior, and culture How microbes may shape cultural cycles of puritanism and promiscuity
