An extensive resource package integrates text and digital media in an easy-to-use format designed to assist instructors in classroom preparation.

    The book documents the adverse environmental effects caused by the indiscriminate use of pesticides. Carson accused the chemical industry of spreading disinformation, and public officials of accepting the industry's marketing claims unquestioningly.The book appeared in September 1962 and the outcry that followed its publication forced the banning of DDT and spurred revolutionary changes in the laws affecting our air, land, and water. Carson’s book was instrumental in launching the environmental movement.

    Ehrlich, author of The Dominant Animal  Biologist Rob Dunn’s Every Little Thing is the story of man’s obsessive quest to catalog life, from nanobacteria to new monkeys. In the tradition of E.O. Wilson, this engaging and fascinating work of popular science follows humanity’s unending quest to discover every living thing in our natural world—from the unimaginably small in the most inhospitable of places on earth to the unimaginably far away in the unexplored canals on Mars.

    The complexity of nature's shapes differs in kind, not merely degree, from that of the shapes of ordinary geometry, the geometry of fractal shapes.Now that the field has expanded greatly with many active researchers, Mandelbrot presents the definitive overview of the origins of his ideas and their new applications. The Fractal Geometry of Nature is based on his highly acclaimed earlier work, but has much broader and deeper coverage and more extensive illustrations.

    This volume highlights the research and findings of this natural scientist. Powerful modern microscopes have confirmed the accuracy of Haeckel's prints, which even in their day, became world famous. Haeckel's portfolio, first published between 1899 and 1904 in separate installments, is described in the opening essays. The plates illustrate Haeckel's fundamental monistic notion of the -unity of all living things- and the wide variety of forms are executed with utmost delicacy. Incipient microscopic organisms are juxtaposed with highly developed plants and animals. The pages, ordered according to geometric and -constructive- aspects, document the oness of the world in its most diversified forms. This collection of plates was not only well-received by scientists, but by artists and architects as well. Rene Binet, a pioneer of glass and iron constructions, Emile Galle, a renowned Art Nouveau designer, and the photographer Karl Blossfeld all make explicit reference to Haeckel in their work.

    Its clear writing style, superior art program, and other learning aids appeal to students in many majors. This edition includes thoroughly updated content and introduces renowned illustrator Dennis Tasa--yet it maintains the proven approach first presented by respected authority Tom L. McKnight more than 20 years ago.

    In these pages you’ll also meet Maya and Zuni, two orphaned baby hummingbirds who hatched from eggs the size of navy beans, and who are little more than air bubbles fringed with feathers. Their lives hang precariously in the balance—but with human help, they may one day conquer the sky. Snowball is a cockatoo whose dance video went viral on YouTube and who’s now teaching schoolchildren how to dance. You’ll meet Harris’s hawks named Fire and Smoke. And you’ll come to know and love a host of other avian characters who will change your mind forever about who birds really are. Each of these birds shows a different and utterly surprising aspect of what makes a bird a bird—and these are the lessons of Birdology: that birds are far stranger, more wondrous, and at the same time more like us than we might have dared to imagine. In Birdology, beloved author of The Good Good Pig Sy Montgomery explores the essence of the otherworldly creatures we see every day. By way of her adventures with seven birds—wild, tame, exotic, and common—she weaves new scientific insights and narrative to reveal seven kernels of bird wisdom. The first lesson of Birdology is that, no matter how common they are, Birds Are Individuals, as each of Montgomery’s distinctive Ladies clearly shows. In the leech-infested rain forest of Queensland, you’ll come face to face with a cassowary—a 150-pound, man-tall, flightless bird with a helmet of bone on its head and a slashing razor-like toenail with which it (occasionally) eviscerates people—proof that Birds Are Dinosaurs. You’ll learn from hawks that Birds Are Fierce; from pigeons, how Birds Find Their Way Home; from parrots, what it means that Birds Can Talk; and from 50,000 crows who moved into a small city’s downtown, that Birds Are Everywhere. They are the winged aliens who surround us. Birdology explains just how very "other" birds are: Their hearts look like those of crocodiles. They are covered with modified scales, which are called feathers. Their bones are hollow. Their bodies are permeated with extensive air sacs. They have no hands. They give birth to eggs. Yet despite birds’ and humans’ disparate evolutionary paths, we share emotional and intellectual abilities that allow us to communicate and even form deep bonds. When we begin to comprehend who birds really are, we deepen our capacity to approach, understand, and love these otherworldly creatures. And this, ultimately, is the priceless lesson of Birdology: it communicates a heartfelt fascination and awe for birds and restores our connection to these complex, mysterious fellow creatures.

    The Topics And Chapters Are Organized In A Sequence That Is Easy To Follow, Beginning With The Most Familiar -- Structure -- And Proceeding To The Less Familiar -- Metabolism -- Then Finishing With Those Topics That Are Probably The Least Familiar To Most Beginning Students -- Genetics, Evolution, The Diversity Of Organisms, And Ecology.

    Whether satirizing bird snobs or relating the traditions and taboos of the birding culture, each essay is as chock-full of helpful information as it is entertaining.

    Pigeons have been worshipped as fertility goddesses and used as crucial communicators in war by every major historical superpower from ancient Egypt to the United States, saving thousands of lives. Yet, without just cause, they are reviled today as “rats of the sky.” How did we come to misunderstand one of mankind’s most helpful and steadfast companions? Author Andrew D. Blechman traveled across the United States and Europe to meet with pigeon fanciers and pigeon haters in a quest to chronicle the pigeon’s transformation from beloved friend to feathered outlaw. Pigeons captures a Brooklyn man’s quest to win the Main Event (the pigeon world’s equivalent of the Kentucky Derby), as well as a pigeon shoot where entrants pay $150 to shoot live pigeons. Blechman tracks down Mike Tyson, the nation’s most famous pigeon lover, and he sheds light on a radical “pro-pigeon underground” in New York City. In Pigeons , Blechman tells for the first time the remarkable story behind this seemingly unremarkable bird.

    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.
