    He sees the angler's environment all around him--in New York's Grand Central Station, in the cement-lined pond of a city park, in a shimmering bonefish flat in the Florida Keys, in the trout streams of the Rocky Mountains. He marvels at the fishing in the turbid Ohio River by downtown Cincinnati, where a good bait for catfish is half a White Castle french fry. The incidentals of the angling experience, the who and the where of it, interest him as much as what he catches and how. The essays contain sharply focused observations of the American outdoors, a place filled with human alterations and detritus that somehow remain defiantly unruined. Frazier's simple love of the sport lifts him to a straight-ahead angling description that's among the best contemporary writing on the subject. The Fish's Eye brings together twenty years of heartfelt, funny, and vivid essays on a timeless pursuit where so many mysteries, both human and natural, coincide.

    In this picture book adaptation of Sy Montgomery and Rebecca Green’s New York Times bestselling How to Be a Good Creature, learn the many surprising lessons animals have to teach us about friendship, compassion, and how to be a better creature in the world.

    News of both the Ice Man's discovery and his age, which was put at over five thousand years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative of a man who died thousands of years ago?In The Seven Daughters of Eve, he gives us a firsthand account of his research into a remarkable gene, which passes undiluted from generation to generation through the maternal line. After plotting thousands of DNA sequences from all over the world, Sykes found that they clustered around a handful of distinct groups. Among Europeans and North American Caucasians, there are, in fact, only seven. This conclusion was staggering: almost everyone of native European descent, wherever they may live throughout the world, can trace their ancestry back to one of seven women, the Seven Daughters of Eve.Naming them Ursula, Xenia, Helena, Velda, Tara, Katrine, and Jasmine, Sykes has created portraits of their disparate worlds by mapping the migratory patterns followed by millions of their ancestors. In reading the stories of these seven women, we learn exactly how our origins can be traced, how and where our ancient genetic ancestors lived, and how we are each living proof of the almost indestructible strands of DNA, which have survived over so many thousands of years. Indeed, The Seven Daughters of Eve is filled with dramatic stories: from Sykes's identification, using DNA samples from two living relatives, of the remains of Tsar Nicholas and Tsaress Alexandra, to the Caribbean woman whose family had been sold into slavery centuries before and whose ancestry Sykes was able to trace back to the Eastern coast of central Africa. Ultimately, Sykes's investigation reveals that, as a race, what humans have in common is more deeply embedded than what separates us.

    Their numbers are in freefall, dropping by nearly 70 percent in the last sixty years, a billion fewer now than in 1950. Extinction stalks the ocean, and there is a danger that the hundred-million-year-old cries of a seabird colony, rolling around in the bays and headlands of high latitudes, will this century become but a memory.

    Topics covered in the book include linear equations, ratios, quadratic equations, special factorizations, complex numbers, graphing linear and quadratic equations, linear and quadratic inequalities, functions, polynomials, exponents and logarithms, absolute value, sequences and series, and much more!The text is structured to inspire the reader to explore and develop new ideas. Each section starts with problems, giving the student a chance to solve them without help before proceeding. The text then includes solutions to these problems, through which algebraic techniques are taught. Important facts and powerful problem solving approaches are highlighted throughout the text. In addition to the instructional material, the book contains well over 1000 problems.This book can serve as a complete Algebra I course, and also includes many concepts covered in Algebra II. Middle school students preparing for MATHCOUNTS, high school students preparing for the AMC, and other students seeking to master the fundamentals of algebra will find this book an instrumental part of their mathematics libraries.656About the author: Richard Rusczyk is a co-author of Art of Problem Solving, Volumes 1 and 2, the author of Art of Problem Solving's Introduction to Geometry.

    A natural history of non-native species of animals currently living and thriving in America focuses on the various experiments, most well-intentioned, that introduced many foreign life forms to the continent.

    McPhee embarks on a fascinating journey across the basement of the continent -- the land masses forming Illinois, Iowa, Nebraska, and thereabouts -- with a professor and geochronologist acting as a guide.

    MacKinnon realized the grassland he grew up on was not the pristine wilderness he had always believed it to be. Instead, his home prairie was the outcome of a long history of transformation, from the disappearance of the grizzly bear to the introduction of cattle. What remains today is an illusion of the wild--an illusion that has in many ways created our world. In 3 beautifully drawn parts, MacKinnon revisits a globe exuberant with life, where lions roam North America and 20 times more whales swim in the sea. He traces how humans destroyed that reality, out of rapaciousness, yes, but also through a great forgetting. Finally, he calls for an "age of restoration," not only to revisit that richer and more awe-filled world, but to reconnect with our truest human nature. MacKinnon never fails to remind us that nature is a menagerie of marvels. Here are fish that pass down the wisdom of elders, landscapes still shaped by "ecological ghosts," a tortoise that is slowly remaking prehistory. "It remains a beautiful world," MacKinnon writes, "and it is its beauty, not its emptiness, that should inspire us to seek more nature in our lives."

    Written by a team of experts and featuring more than 320 illustrations, 418 photographs, and 123 maps, this new guide offers more authoritative, up-to-date, and accessible information than any book previously published on the subject.Organized by the four major groups of marine mammals—marine fissipeds, pinnipeds, cetaceans, and sirenians—the species descriptions include:Full-color paintings, some depicting males and females, juveniles, subspecies, or special features. Color photographs showing appearance in the wild and illustrating typical behaviors. Life history data, including length and weight at various life stages, and life span. Range and habitat text and a full-color range map based on the most current information. Facts about social organization, surface behaviors, swimming, and diving. Information on mating behavior, breeding, and the rearing of young. Details about food items and foraging techniques. Estimates of population in the wild, plus current and historic threats.A general introduction outlines the evolution and taxonomy of marine mammals, distribution, migration, watching guidelines, identification techniques, organizations and laws that protect marine mammals, and more.Introductions to groups include comparative size illustrations, discussion of behaviors particular to the group, and other unique features.A useful illustrated glossary of terms and an index of species names complete the guide.Exquisitely detailed illustrations, stunning photographs, and clearly written text combine to make this an indispensible reference source for marine mammal watchers and anyone interested in the natural world.

    But in recent decades, these claims have eroded, or even been disproven outright, by a revolution in the study of animal cognition. Take the way octopuses use coconut shells as tools; elephants that classify humans by age, gender, and language; or Ayumu, the young male chimpanzee at Kyoto University whose flash memory puts that of humans to shame. Based on research involving crows, dolphins, parrots, sheep, wasps, bats, whales, and of course chimpanzees and bonobos, Frans de Waal explores both the scope and the depth of animal intelligence. He offers a firsthand account of how science has stood traditional behaviorism on its head by revealing how smart animals really are, and how we’ve underestimated their abilities for too long.People often assume a cognitive ladder, from lower to higher forms, with our own intelligence at the top. But what if it is more like a bush, with cognition taking different forms that are often incomparable to ours? Would you presume yourself dumber than a squirrel because you’re less adept at recalling the locations of hundreds of buried acorns? Or would you judge your perception of your surroundings as more sophisticated than that of a echolocating bat? De Waal reviews the rise and fall of the mechanistic view of animals and opens our minds to the idea that animal minds are far more intricate and complex than we have assumed. De Waal’s landmark work will convince you to rethink everything you thought you knew about animal—and human—intelligence.
