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.

    This fascination is driven by the ancient chemical forces that first drew humans and animals together. It is also the same biology that transformed wolves into dogs and skittish horses into valiant comrades that would carry us into battle.Made for Each Other is the first book to explain how this chemistry of attraction and attachment flows through--and between--all mammals to create the profound emotional bonds humans and animals still feel today.Drawing on recent discoveries from neuroscience, evolutionary biology, behavioral psychology, archeology, as well as her own investigations, Meg Daley Olmert explains why the brain chemistry humans and animals trigger in each other also has a profound effect on our mental and physical well being.This lively and original investigation asks what happens when the bond is severed. If thousands of years of caring for animals infused us with a biology that shaped our hearts and minds, do we dare turn our back on it? Daley Olmert makes a compelling and scientific case for what our hearts have always known, that we were, and always will be, made for each other.

    This is the funny, poignant story of their two decades together.On Valentine's Day 1985, biologist Stacey O'Brien first met a four-day-old baby barn owl -- a fateful encounter that would turn into an astonishing 19-year saga. With nerve damage in one wing, the owlet's ability to fly was forever compromised, and he had no hope of surviving on his own in the wild. O'Brien, a young assistant in the owl laboratory at Caltech, was immediately smitten, promising to care for the helpless owlet and give him a permanent home. Wesley the Owl is the funny, poignant story of their dramatic two decades together. With both a tender heart and a scientist's eye, O'Brien studied Wesley's strange habits intensively and first-hand -- and provided a mice-only diet that required her to buy the rodents in bulk (28,000 over the owl's lifetime). As Wesley grew, she snapped photos of him at every stage like any proud parent, recording his life from a helpless ball of fuzz to a playful, clumsy adolescent to a gorgeous, gold-and-white, macho adult owl with a heart-shaped face and an outsize personality that belied his 18-inch stature. Stacey and Wesley's bond deepened as she discovered Wesley's individual personality, subtle emotions, and playful nature that could also turn fiercely loyal and protective -- though she could have done without Wesley's driving away her would-be human suitors! O'Brien also brings us inside the prestigious research community, a kind of scientific Hogwarts where resident owls sometimes flew freely from office to office and eccentric, brilliant scientists were extraordinarily committed to studying and helping animals; all of them were changed by the animal they loved. As O'Brien gets close to Wesley, she makes important discoveries about owl behavior, intelligence, and communication, coining the term "The Way of the Owl" to describe his inclinations: he did not tolerate lies, held her to her promises, and provided unconditional love, though he was not beyond an occasional sulk. When O'Brien develops her own life-threatening illness, the biologist who saved the life of a helpless baby bird is herself rescued from death by the insistent love and courage of this wild animal. Enhanced by wonderful photos, Wesley the Owl is a thoroughly engaging, heartwarming, often funny story of a complex, emotional, non-human being capable of reason, play, and, most important, love and loyalty. It is sure to be cherished by animal lovers everywhere.

    Ranging from the depths of the ocean to the most arid corners of the land, Caspar Henderson captures the beauty and bizzareness of the many living forms we thought we knew and some we could never have contemplated, inviting us to better imagine the precarious world we inhabit.A witty, vivid blend of cutting edge natural history and meditative reflections, The Book of Barely Imagined Beings is infectious and celebratory about the sheer ingenuity and variety of life.

    Fully grown they can measure 10 feet and weigh close to 2,000 pounds, but at birth they are just 20 ounces. Creatures that may wander thousands of miles over the course of a year, they begin life in a snowdrift.Human encounters with these legendary beasts are cause for both excitement and apprehension. Tales throughout history describe the ferocity of polar bear attacks on humans; but human hunting of polar bears has exacted a far larger toll, obliging Arctic nations to try to protect their region’s iconic species before it’s too late.Now, however, another threat to the polar bears’ survival has emerged, one that is steadily removing sea ice and the life it supports. Without this habitat, polar bears cannot exist. The Great White Bear celebrates the story of this unique species. Through a blend of history, both natural and human, through myth and reality and observations both personal and scientific, Kieran Mulvaney masterfully provides a context for readers to consider the polar bear, its history, its life, and its uncertain fate.

    The Birder's Handbook is the first of its kind: a portable library of fascinating information not included in your identification guide. For each of the 646 species of birds that breed in North America, The Birder's Handbook will tell you at a glance: * Where the bird nests, and which sex(es) build(s) the nest;* How many eggs the bird lays, what they look like, which patent incubates and for how long, and how the young are cared for;* Food preferences and foraging habits.You will also find information about displays and mating, wintering, conservation status, and much more. In addition, The Birder's Handbook contains some 250 short essays covering all aspects of avian natural history.

    Now, faced with the threat of nuclear weapons and the effects of climate change, it seems our innate tendencies for violence and invention have led us to a crucial fork in our road. Where did these traits come from? Are they part of our species immutable destiny? Or is there hope for our species’ future if we change? With fascinating facts and his unparalleled readability, Diamond intended his book to improve the world that today’s young people will inherit. Triangle Square’s The Third Chimpanzee for Young People is a book for future generation and the future they’ll help build.

    Robin Moore has a passion for frogs and a fascination with finding new and "lost" species. In 2010, he spearheaded the worldwide "Search for Lost Frogs" campaign, which coordinated the efforts of 33 teams of scientists in 19 countries on five continents in a quest to find 100 species of amphibian not seen in over a decade."In Search of Lost Frogs" is a stunning record of Moore's journey and what he and his team did (or did not) find. The book is overflowing with exquisite close-up photographs by Moore that display the frogs' remarkable coloring and camouflage, and reveal their diminutive size -- many of the frogs are less than 5 cm long, if that. Moore's engaging text tells the story of the expedition, its highs and lows, discoveries and failures, and the campaign's ongoing work.The book's first half covers what frogs do for the health of the planet, the slippery slope of extinction, what is being done to monitor frog populations and find lost species, the Lazarus project (which aims to "revive" lost species) and the author's career-long resolve to find the Mesopotamia Beaked Toad.The second half of the book is about the searches. Moore describes the struggles, victories and dangers as well as the science. He takes readers along as his team trudge through rainforest, climb mountains and paddle rivers in search of the lost frogs, some not seen for more than a century. He tells a story of perseverance, disappointment, rediscovery, resilience, but ultimately of hope, written with passion and illustrated with superb photographs. And a surprise ending: they found 15 lost frogs.They include: In Ecuador, the Rio Pescado Stubfoot Toad, not seen since 1995 In Haiti, six rediscoveries, including the Ventriloquial Frog and Mozart's Frog, both lost for 20 years In India, the Dehradun Stream Frog, last seen (and only once) in 1985; the Elegant Tree Frog (1937); the Chalazodes Bubble Nest Frog (1874); the Anamalai Dot-Frog (1938) In Democratic Republic of Congo, the Omaniundu Reed Frog (1979) In Ivory Coast, the Mount Nimba Reed Frog (1967).Naturalists, lovers of all things frog, schools and interested general readers will enjoy the stunning photographs, the science and the adventurous stories of discovery.

    Visiting it almost daily for one year to trace nature’s path through the seasons, he brings the forest and its inhabitants to vivid life.Each of this book’s short chapters begins with a simple observation: a salamander scuttling across the leaf litter; the first blossom of spring wildflowers. From these, Haskell spins a brilliant web of biology and ecology, explaining the science that binds together the tiniest microbes and the largest mammals and describing the ecosystems that have cycled for thousands—sometimes millions—of years. Each visit to the forest presents a nature story in miniature as Haskell elegantly teases out the intricate relationships that order the creatures and plants that call it home.Written with remarkable grace and empathy, The Forest Unseen is a grand tour of nature in all its profundity. Haskell is a perfect guide into the world that exists beneath our feet and beyond our backyards.

    Scientists are confident that there is alien life across the universe yet we have not moved beyond our perception of 'aliens' as Hollywood stereotypes. The time has come to abandon our fixation on alien monsters and place our expectations on solid scientific footing.Using his own expert understanding of life on Earth and Darwin's theory of evolution - which applies throughout the universe - Cambridge zoologist Dr Arik Kershenbaum explains what alien life must be like: how these creatures will move, socialise and communicate.For example, by observing fishes whose electrical pulses indicate social status, we can see that other planets might allow for communication by electricity. As there was evolutionary pressure to wriggle along a sea floor, Earthling animals tend to have left/right symmetry; on planets where creatures evolved mid-air or in soupy tar they might be lacking any symmetry at all.Might there be an alien planet with supersonic animals? Will they scream with fear, act honestly, or have technology? Is the universe swarming with robots? Dr Kershenbaum uses cutting-edge science to paint an entertaining and compelling picture of extra-terrestrial life.The Zoologist's Guide to the Galaxy is the story of how life really works, on Earth and in space.***'If you don't want to be surprised by extraterrestrial life, look no further than this lively overview of the laws of evolution that have produced life on earth' - Frans de Waal, author of Mama's Last Hug - Animal Emotions and What They Tell Us about Ourselves'A fun, and thoroughly biological, exploration of possible and impossible alien beings. If you'd love to know what real aliens from other planets might really be like, this is the book for you' - Susan Blackmore, author of Seeing Myself'Surveying the deep-time of evolution on Earth and his own cutting-edge research into animal communication, Kershenbaum provides a fascinating insight into the deepest of questions: what might an alien actually look like'- Lewis Dartnell, author of Origins'Arik Kershenbaum takes us on a joyous voyage of animal diversity and illustrates the singular importance of natural selection in explaining life - here on Earth - and what will likely be discovered throughout the galaxy.

    It isn't surprising then that Koestler should hark back to the opprobrious case of Dr Paul Kammerer, an Austrian biologist whose controversial experiments on the evolutionary process (using among other amphibians the midwife toad, so named for its mating habits) were denounced as fraudulent in 1926 by an American herpetologist, G.K. Noble, in the pages of Nature-- whereupon Kammerer blew his brains out, seemingly confirming the old saw "confession is suicide & suicide is confession." But Koestler's investigation, begun as a study of a scientist who betrayed his commitment to truth, indicates that Kammerer, far from being a laboratory quisling, was probably innocent; a victim of an unknown colleague's machinations to discredit his work & therefore in the larger sense a casualty of the still unresolved war between the nco-Darwinist evolutionists who support the random mutation theory & the heretical Lamarckians who maintain (as did Kammerer's experiments) that acquired characteristics can be transmitted from one generation to another. "I did not start with the intention to rehabilitate Paul Kammerer," says Koestler, "but I ended up with an attempt to do so." In the course of that effort he uses his skill as both inventive fantast & experienced researcher to give the midwife toad case a sense of drama & veracity. Those who found The Double Helix satisfying will enjoy this one too, no matter if they agree with Koestler's conclusions.--Kirkus (edited)

    She introduces us to renowned futurists like Stewart Brand and scientists like George Church, who are harnessing the powers of CRISPR gene editing in the hopes of “reviving” extinct passenger pigeons, woolly mammoths, and heath hens. She speaks with Nikita Zimov, who together with his eclectic father Sergey, is creating Siberia’s Pleistocene Park—a daring attempt to rebuild the mammoth’s ancient ecosystem in order to save earth from climate apocalypse. Through interviews with these and other thought leaders, Wray reveals the many incredible opportunities for research and conservation made possible by this emerging new field.But we also hear from more cautionary voices, like those of researcher and award-winning author Beth Shapiro (How to Clone a Woolly Mammoth) and extinction philosopher Thomas van Dooren. Writing with passion and perspective, Wray delves into the larger questions that come with this incredible new science, reminding us that de-extinction could bring just as many dangers as it does possibilities. What happens, for example, when we bring an “unextinct” creature back into the wild? How can we care for these strange animals and ensure their comfort and safety—not to mention our own? And what does de-extinction mean for those species that are currently endangered? Is it really ethical to bring back an extinct passenger pigeon, for example, when countless other birds today will face the same fate?By unpacking the many biological, technological, ethical, environmental, and legal questions raised by this fascinating new field, Wray offers a captivating look at the best and worst of resurrection science.

    They evolved from land-roaming, dog-like creatures into animals that move like fish, breathe like us, can grow to 300,000 pounds, live 200 years and roam entire ocean basins. Whales fill us with terror, awe, and affection--yet we know hardly anything about them, and they only enter our awareness when they die, struck by a ship or stranded in the surf. Why did it take whales over 50 million years to evolve to such big sizes, and how do they eat enough to stay that big? How did their ancestors return from land to the sea? Why do they beach themselves? What do their lives tell us about our oceans, and evolution as a whole? Importantly, in the sweepstakes of human-driven habitat and climate change, will whales survive?Nick Pyenson's research has given us the answers to some of our biggest questions about whales. Nick's rich storytelling takes us to the cool halls deep inside the Smithsonian's priceless fossil collection, to the frigid fishing decks on Antarctic whaling stations, and to the blazing hot desert of Chile where scientists race against time to document the largest fossil whalebone site on earth. Spying on Whales is science writing at its best: an author who is an incredible, passionate writer, at the forefront of his field, on a topic that invokes deep fascination.

    Our species emerged out of the depths of time into a world already populated by these great carnivores. Before we mastered iron and later developed firearms, we had few defences against bears--only watchful caution and elaborate ceremonies and sacrifices to ward off fear.Where human populations grow, bears have traditionally dwindled or disappeared. But when we return to the wild, to places where bears still survive, all our primeval fears awaken again. The risk of an automobile accident on the way to bear country far outstrips the risk of a close-range encounter with a bear, but it's the bear that worries us as we hurtle down the pavement at a hundred kilometres an hour.In this timely and sensitive book, Kevin Van Tighem calls on decades of experience, knowledge and understanding in order to enlighten readers about our relationship with and attitude toward bears. Along the way we are confronted with the realities confronting these great animals as a result of our ever-expanding human population and their ever-shrinking natural habitat. Through historical research, field observation, practical advice, personal anecdotes and an array of stunning photos, Van Tighem has written a comprehensive book that is meant to demystify bears in order to promote a deeper understanding of these powerful yet vulnerable creatures.
