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.

    But was it a savage sheep killer or a shy, fussy, nocturnal feeder? And did it really drink its victims' blood? Once reviled, feared and slaughtered by government decree, the myth of the Tasmanian Tiger continues to grow. So treasured is it now, the Tasmanian Tiger has become the official logo of the island that wiped it out and a symbol of the conservation movement world-wide.A number of Australian species have miraculously reappeared after being labelled as extinct. Perhaps the Tiger is still with us. And if it's not, can it be brought back by cloning?

    Diane Ackerman draws from sources as diverse as meteorology, world religion, etymology, art history, and poetry in order to celebrate that moment in which the deepest arcades of life and matter become visible. From spring in Ithaca, New York, to winter in Palm Beach, Florida, Dawn Light is an impassioned call to revel in our numbered days on a turning earth.

    In The Horse, the journalist and equestrienne Wendy Williams brings that story brilliantly to life.Williams chronicles the 56-million-year journey of horses as she visits with horse experts around the world, revealing what our biological affinities and differences can tell us about the bond between horses and humans, and what our noble companion may think and feel. Indeed, recent scientific breakthroughs regarding the social and cognitive capacities of the horse and its ability to adapt to changing ecosystems indicate that this animal is a major evolutionary triumph.Williams charts the course that leads to our modern Equus-from the protohorse to the Dutch warmbloods, thoroughbreds, and miniature horses of the twenty-first century. She observes magnificent ancient cave art that signals a deep respect and admiration for horses well before they were domesticated, visits the mountains of Wyoming with an expert in equine behavior to understand the dynamics of free-roaming mustangs, witnesses the fluid gracefulness of the famous Lipizzaners of Vienna, contemplates what life is like for the sure-footed, mustachioed Garrano horses who thrive on the rugged terrain of Galicia, celebrates the Takhi horses of Mongolia, and more. She blends profound scientific insights with remarkable stories to create a unique biography of the horse as a sentient being with a fascinating past and a finely nuanced mind.The Horse is a revelatory account of the animal who has been at our side through the ages, carrying us into battle and traveling with us across the plains. Enriched by Wendy Williams's own experience with horses, The Horse is a masterful work of narrative nonfiction that pays tribute to this champion of the natural world.

    Line" the author introduces his friend John McPhee, a bush-pilot fish-and-game warden in northern Maine, who is also a writer. The two men met after the flying warden wrote to The New Yorker complaining that someone was using his name. Maine also is the milieu of "Heirs of General Practice," McPhee's highly acclaimed report—virtually a book in itself—on the new medical specialty called family practice. Much of it takes place in the examining rooms of a dozen young physicans in various rural communities, where they are seen in the context of their work with a great many patients of all ages.Two relatively short pieces revisit the subjects of earlier McPhee books. "Ice Pond" demonstrates anew the innovative genius of the physicist Theodore B. Taylor, who developed a way of making and using with impressive results in the conservation of the electrical energy. "Open Man" describes a summer day in New Jersey in the company of Senator Bill Bradley.In "Minihydro," various small-scale entrepreneurs in New York State set up turbines at nineteenth-century mill sites and sell electricity to power companies. A nice little country waterfall can earn as much as two hundred dollars a year for someone with such a turbine. And, "Under the Snow," McPhee Goes back into black bear's dens in Pensylvania in winter, where he becomes intoxicated with affection for some five-pound cubs. They remind him of his daughters.

    Dickson Despommier's visionary book provides a blueprint for securing the world's food supply and at the same time solving one of the gravest environmental crises facing us today."--StingImagine a world where every town has their own local food source, grown in the safest way possible, where no drop of water or particle of light is wasted, and where a simple elevator ride can transport you to nature's grocery store - imagine the world of the vertical farm.When Columbia professor Dickson Despommier set out to solve America's food, water, and energy crises, he didn't just think big - he thought up. Despommier's stroke of genius, the vertical farm, has excited scientists, architects, and politicians around the globe. Now, in this groundbreaking book, Despommier explains how the vertical farm will have an incredible impact on changing the face of this planet for future generations.Despommier takes readers on an incredible journey inside the vertical farm, buildings filled with fruits and vegetables that will provide local food sources for entire cities.Vertical farms will allow us to:- Grow food 24 hours a day, 365 days a year- Protect crops from unpredictable and harmful weather- Re-use water collected from the indoor environment- Provide jobs for residents- Eliminate use of pesticides, fertilizers, or herbicides- Drastically reduce dependence on fossil fuels- Prevent crop loss due to shipping or storage- Stop agricultural runoffVertical farms can be built in abandoned buildings and on deserted lots, transforming our cities into urban landscapes which will provide fresh food grown and harvested just around the corner. Possibly the most important aspect of vertical farms is that they can built by nations with little or no arable land, transforming nations which are currently unable to farm into top food producers. In the tradition of the bestselling The World Without Us, The Vertical Farm is a completely original landmark work destined to become an instant classic

    He was the most influential member of the aristocratic Tolstoy family. His first publications were three autobiographical novels, Childhood, Boyhood, and Youth (1852-1856). They tell of a rich landowner's son and his slow realization of the differences between him and his peasants. As a fiction writer Tolstoy is widely regarded as one of the greatest of all novelists, particularly noted for his masterpieces War and Peace (1869) and Anna Karenina (1877). In their scope, breadth and realistic depiction of 19th-century Russian life, the two books stand at the peak of realist fiction. As a moral philosopher Tolstoy was notable for his ideas on nonviolent resistance through works such as The Kingdom of God is Within You (1894). During his life, Tolstoy came to the conclusion that William Shakespeare is a bad dramatist and not a true artist at all. Tolstoy explained his views in a critical essay on Shakespeare written in 1903.

    Gould explores recapitulation as an idea that intrigued politicians and theologians as well as scientists. He shows that Haeckel's hypothesis--that human fetuses with gill slits are, literally, tiny fish, exact replicas of their water-breathing ancestors--had an influence that extended beyond biology into education, criminology, psychoanalysis (Freud and Jung were devout recapitulationists), and racism. The theory of recapitulation, Gould argues, finally collapsed not from the weight of contrary data, but because the rise of Mendelian genetics rendered it untenable.Turning to modern concepts, Gould demonstrates that, even though the whole subject of parallels between ontogeny and phylogeny fell into disrepute, it is still one of the great themes of evolutionary biology. Heterochrony--changes in developmental timing, producing parallels between ontogeny and phylogeny--is shown to be crucial to an understanding of gene regulation, the key to any rapprochement between molecular and evolutionary biology. Gould argues that the primary evolutionary value of heterochrony may lie in immediate ecological advantages for slow or rapid maturation, rather than in long-term changes of form, as all previous theories proclaimed.Neoteny--the opposite of recapitulation--is shown to be the most important determinant of human evolution. We have evolved by retaining the juvenile characters of our ancestors and have achieved both behavioral flexibility and our characteristic morphology thereby (large brains by prolonged retention of rapid fetal growth rates, for example).Gould concludes that "there may be nothing new under the sun, but permutation of the old within complex systems can do wonders. As biologists, we deal directly with the kind of material complexity that confers an unbounded potential upon simple, continuous changes in underlying processes. This is the chief joy of our science."

    Brower's voice is passionate, perfectly cadenced, humorous, and very wise. And original: while most writers point to where we are, this one draws the map.?Edward O. Wilson, author, "The Diversity of Life and Naturalist"Credited with galvanizing an entire generation of environmentalists in the 60's, David Brower, the highly respected "archdruid" of the modern environmental movement, recalls with wit and wisdom his 50 years of controversial activism and offers an inspired strategy for the next generation of "those who would save the Earth."In this intelligent and engaging chronicle of his years as an agitatator for the planet, Brower points out the irony that since the first Earth Day 25 years ago, we've lost one-seventh of the world's productive land to pollution, clearcutting, and pavement-and our population has doubled! From the politics of preserving the environment and how to use New York-style PR to save tigers and dolphins, to reengineering cities, the future of hypercars, and his vision for the Earth Corps, Brower takes us on a sweeping journey of what has been and what could be if we apply CPR (Conservation, Preservation, Restoration) to our wounded world. Printed on entirely tree-free kenaf paper, "Let the Mountains Talk, Let the Rivers Run" follows its own prescription for saving the world's forests.TABLE OF CONTENTSCPR for the Earth: An InvitationPART I: OPPORTUNITIES1.

    Like her more famous novels, Alcott tells stories of young women interacting with people and events from the late 1800s. A great addition to the Alcott library of stories.

    Now, Heller chronicles this hair-raising journey, whose mission was to stop illegal whaling in the stormy, remote seas off Antarctica. 288.

    She travels through Laos, Cambodia, and Thailand with an affable biology professor and an array of local officials, guides, and interpreters, joining a search for "what could be the first new bear species to be reported in over a century." Sightings and rumors from isolated border regions had spoken of a blond bear, which might represent an addition to the planet's eight known species -- or an exotic variation on a more familiar theme. Braving rickety airplanes, army ants, and mystery illnesses, Montgomery journeys through a region of tremendous beauty that is under severe strain from human activities. Disquisitions on the mythical manifestations of bears; the disturbing surge in international wildlife trafficking; and the customs of Thai hill tribes add flavor and context to the story. And while Montgomery is disturbed by certain practices -- like the amputation of bear paws for the cookpot -- she tries to place them within the context of differing cultural beliefs. Her wise, witty, and humane account is equally concerned with people, and their responses to the landscapes and creatures around them. And while there are plenty of books about searching for vanishing or unknown species in the world's last wild places, the quality of Montgomery's writing sets this one apart. Jonathan Cook
