The pages take the reader on a wild narrative ride through the world of squid science and adventure, along the way addressing some riddles about what intelligence is, and what monsters lie in the deep. In addition to squid, both giant and otherwise, Kraken examines other equally enthralling cephalopods, including the octopus and the cuttlefish, and explores their otherworldly abilities, such as camouflage and bioluminescence. Accessible and entertaining, Kraken is also the first substantial volume on the subject in more than a decade and a must for fans of popular science.

    Legendary marine scientist Sylvia Earle portrays a planet teetering on the brink of irreversible environmental crisis.In recent decades we’ve learned more about the ocean than in all previous human history combined. But, even as our knowledge has exploded, so too has our power to upset the delicate balance of this complex organism. Modern overexploitation has driven many species to the verge of extinction, from tiny but indispensable biota to magnificent creatures like tuna, swordfish, and great whales. Since the mid-20th century about half our coral reefs have died or suffered sharp decline; hundreds of oxygen-deprived "dead zones" blight our coastal waters; and toxic pollutants afflict every level of the food chain.Fortunately, there is reason for hope, but what we do—or fail to do—in the next ten years may well resonate for the next ten thousand. The ultimate goal, Earle argues passionately and persuasively, is to find responsible, renewable strategies that safeguard the natural systems that sustain us. The first step is to understand and act upon the wise message of this accessible, insightful, and compelling book.

    The set includes thirty-one 30-minute MCAT practice exams with answers and explanations and more than 1,600 MCAT questions.

    There were bacteria in volcanic hydrothermal vents on the ocean floor, single-celled algae in Antarctic ice floes, and fungi in the cooling pools of nuclear reactors.But might there be life stranger than the most extreme extremophile? Might there be, somewhere, another kind of life entirely? In fact, scientists have hypothesized life that uses ammonia instead of water, life based not in carbon but in silicon, life driven by nuclear chemistry, and life whose very atoms are unlike those in life we know. In recent years some scientists have begun to look for the tamer versions of such life on rock surfaces in the American Southwest, in a “shadow biosphere” that might impinge on the known biosphere, and even deep within human tissue. They have also hypothesized more radical versions that might survive in Martian permafrost, in the cold ethylene lakes on Saturn’s moon Titan, and in the hydrogen-rich atmospheres of giant planets in other solar systems. And they have imagined it in places off those worlds: the exotic ices in comets, the vast spaces between the stars, and—strangest of all—parallel universes.Distilling complex science in clear and lively prose, David Toomey illuminates the research of the biological avant-garde and describes the workings of weird organisms in riveting detail. His chapters feature an unforgettable cast of brilliant scientists and cover everything from problems with our definitions of life to the possibility of intelligent weird life. With wit and understanding that will delight scientists and lay readers alike, Toomey reveals how our current knowledge of life forms may account for only a tiny fraction of what’s really out there.

    These small fish form a species flock -- closely related species that have descended from a common ancestor and radiated, or fanned, into different specializations -- that is the most spectacular in the world, fascinating anatomists, ecologists, ethologists, and evolutionary biologists alike. The process of speciation was still under way until just recently, when the introduction of the large, predatory Nile perch so disrupted the Lake's intricate ecosystem that the glorious spectrum of cichlids has almost vanished. Darwin's Dreampond tells the evolutionary story of the extraordinary "furu" and the battlefield leading to extinction. Tijs Goldschmidt skillfully blends a masterful discussion of the principles of neo-Darwinian evolution and speciation with a history of Lake Victoria's ecosystem. The science unfolds in the context of the engaging first-person narrative of Goldschmidt's adventures and misadventures as a field researcher. An astute observer and a clear and witty writer, he warmly portrays the colors and textures of the landscapes and the lives of the local people as he interacts with them during the course of his fieldwork.

    It contains, however, a number of deeper messages related to some of the most basic and important principles of modern biology. The bees are merely the actors that take us into the realm of physiology, genetics, reproduction, biophysics and learning, and that introduce us to the principles of natural selection underlying the evolution of simple to complex life forms. The book destroys the cute notion of bees as anthropomorphic icons of busy self-sacrificing individuals and presents us with the reality of the colony as an integrated and independent being—a superorganism with its own, almost eerie, emergent group intelligence. We are surprised to learn that no single bee, from queen through drone to sterile worker, has the oversight or control over the colony. Instead, through a network of integrated control systems and feedbacks, and communication between individuals, the colony arrives at consensus decisions from the bottom up through a type of swarm intelligence. Indeed, there are remarkable parallels between the functional organization of a swarming honeybee colony and vertebrate brains.

    1 comes a fascinating chronicle of life’s history told not through the fossil record but through the stories of organisms that have survived, almost unchanged, throughout time. Evolution, it seems, has not completely obliterated its tracks as more advanced organisms have evolved; the history of life on earth is far older—and odder—than many of us realize.   Scattered across the globe, these remarkable plants and animals continue to mark seminal events in geological time. From a moonlit beach in Delaware, where the hardy horseshoe crab shuffles its way to a frenzy of mass mating just as it did 450 million years ago, to the dense rainforests of New Zealand, where the elusive, unprepossessing velvet worm has burrowed deep into rotting timber since before the breakup of the ancient supercontinent, to a stretch of Australian coastline with stromatolite formations that bear witness to the Precambrian dawn, the existence of these survivors offers us a tantalizing glimpse of pivotal points in evolutionary history. These are not “living fossils” but rather a handful of tenacious creatures of days long gone.   Written in buoyant, sparkling prose, Horseshoe Crabs and Velvet Worms is a marvelously captivating exploration of the world’s old-timers combining the very best of science writing with an explorer’s sense of adventure and wonder.

    This thorough revision provides a survey by groups, emphasizing adaptive morphology and physiology, while covering anatomical ground plans and basic developmental patterns. New co-author Richard Fox brings to the revision his expertise as an ecologist, offering a good balance to Ruppert's background as a functional morphologist. Rich illustrations and extensive citations make the book extremely valuable as a teaching tool and reference source.

    Wilson, J. Craig Venter, and Freeman Dyson.Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come--and takes a brilliantly educated guess at where we're heading.Freeman Dyson borrows from science fiction to contemplate real questions about what constitutes the stuff of life. Richard Dawkins and J. Craig Venter discuss the revelatory similarity of genes to digital information. Matt Ridley argues that nature and nurture are intricately intertwined.Steven Strogatz celebrates the spectacular mathematical synchronicity of fireflies. Edward O. Wilson reveals what ants can teach us about building a superorganism--and, in turn, about how cells build an organism. Elsewhere, David Haig reports new findings on how mothers and fathers individually influence the human genome, while Robert Trivers explores the opposing functions of the conscious and unconscious minds. And there's much more in this fascinating volume.We may never have all the answers. But the thinkers collected in Life are asking questions that will keep us dreaming for generations.

    The species that survive will be the ones that are most compatible with us: the weedy species--from mosquitoes to coyotes--that thrive in continually disturbed human-dominated environments. The End of the Wild is a wake-up call. Marshaling evidence from the last ten years of research on the environment, Stephen Meyer argues that nothing--not national or international laws, global bioreserves, local sustainability schemes, or wildlands--will change the course that has been set. Like it or not, we can no longer talk about conserving nature, only managing what is left. The race to save biodiversity is over.But that doesn't mean our work is over. The End of the Wild is also a call to action. Without intervention, the surviving ecosystems we depend on for a range of services--including water purification and flood and storm damage contro--could fail and the global spread of invasive species (pests, parasites, and disease-causing weedy species) could explode. If humanity is to survive, Meyer argues, we have no choice but to try to manage the fine details. We must move away from the current haphazard strategy of protecting species in isolation and create trans-regional meta-reserves, designed to protect ecosystem functions rather than species-specific habitats.
