He was a city boy, unsure of what lay ahead. When he entered the forest, which would go on to become one of the last strongholds of wild tigers, it had a profound effect on him, changing his life forever.For the next forty years, he studied nearly 200 Ranthambhore tigers, spending every waking moment in close proximity to these magnificent animals. Of the various tigers he observed a handful became extra special, and it is these which come to glorious life in this book. They include Padmini, the Queen Mother, the first tiger the author got to know well; Genghis, the master predator, who invented a way of killing prey in water, the first time this had been observed anywhere in the world; Noon, one of his all-time favourites, who received her name because she was most active in the middle of the day; Broken Tooth, an exceptionally gentle male; Laxmi, a devoted mother, whose methods of raising her cubs revolutionized tiger studies; Machli, the most famous tigress in Ranthambhore, and several more.

    Gruchow turns a naturalist's eye on a wilderness of wolves, moose, and loons as he visits national parks and other scenic spots. Drawing on the works of Thoreau and Wendell Berry, he explores the relationship of person to place.

    Learners develop useful and relevant vocabulary while exploring and expanding critical thinking skills.

    Thanks largely to YouTube clips posted by the sloth orphanage in Costa Rica, sloths have attracted a vast audience of admirers. Instead of seeing them as ridiculous anachronisms of which we know little, they have turned into creatures considered by many to be the most endearing on earth.Over much the same period, scientific investigations have also changed our view of sloths. No longer are they seen as total misfits in the modern world but, in the words of one specialist sloth investigator, they are 'masters of an alternative lifestyle'.In this wonderfully entertaining celebration of this most unique of creatures, William Hartston reveals the fascinating history of the sloth, from the prehistoric ground sloth to modern pygmy sloths in Panama, explores the current state of the science of sloths and reveals the truth behind sloth behaviour.

    Throughout his celebrated career, Schaller has spent more time in Tibet than in any other part of the world, devoting more than thirty years to the wildlife, culture, and landscapes that captured his heart and continue to compel him to protect them.  Tibet Wild is Schaller’s account of three decades of exploration in the most remote stretches of Tibet: the wide, sweeping rangelands of the Chang Tang and the hidden canyons and plunging ravines of the southeastern forests. As engaging as he is enlightening, Schaller illustrates the daily struggles of a field biologist trying to traverse the impenetrable Chang Tang, discover the calving grounds of the chiru or Tibetan antelope, and understand the movements of the enigmatic snow leopard.    As changes in the region accelerated over the years, with more roads, homes, and grazing livestock, Schaller watched the clash between wildlife and people become more common—and more destructive. Thus what began as a purely scientific endeavor became a mission: to work with local communities, regional leaders, and national governments to protect the unique ecological richness and culture of the Tibetan Plateau.    Whether tracking brown bears, penning fables about the tiny pika, or promoting a conservation preserve that spans the borders of four nations, Schaller has pursued his goal with a persistence and good humor that will inform and charm readers.  Tibet Wild is an intimate journey through the changing wilderness of Tibet, guided by the careful gaze and unwavering passion of a life-long naturalist.

    The consequences of losing beavers were profound: streams eroded, wetlands dried up, and species from salmon to swans lost vital habitat. Today, a growing coalition of “Beaver Believers”―including scientists, ranchers, and passionate citizens―recognizes that ecosystems with beavers are far healthier, for humans and non-humans alike, than those without them. From the Nevada deserts to the Scottish highlands, Believers are now hard at work restoring these industrious rodents to their former haunts. Eager is a powerful story about one of the world’s most influential species, how North America was colonized, how our landscapes have changed over the centuries, and how beavers can help us fight drought, flooding, wildfire, extinction, and the ravages of climate change. Ultimately, it’s about how we can learn to coexist, harmoniously and even beneficially, with our fellow travelers on this planet.

    In How to Clone a Mammoth, Beth Shapiro, evolutionary biologist and pioneer in "ancient DNA" research, walks readers through the astonishing and controversial process of de-extinction. From deciding which species should be restored, to sequencing their genomes, to anticipating how revived populations might be overseen in the wild, Shapiro vividly explores the extraordinary cutting-edge science that is being used--today--to resurrect the past. Journeying to far-flung Siberian locales in search of ice age bones and delving into her own research--as well as those of fellow experts such as Svante Paabo, George Church, and Craig Venter--Shapiro considers de-extinction's practical benefits and ethical challenges. Would de-extinction change the way we live? Is this really cloning? What are the costs and risks? And what is the ultimate goal?Using DNA collected from remains as a genetic blueprint, scientists aim to engineer extinct traits--traits that evolved by natural selection over thousands of years--into living organisms. But rather than viewing de-extinction as a way to restore one particular species, Shapiro argues that the overarching goal should be the revitalization and stabilization of contemporary ecosystems. For example, elephants with genes modified to express mammoth traits could expand into the Arctic, re-establishing lost productivity to the tundra ecosystem.Looking at the very real and compelling science behind an idea once seen as science fiction, How to Clone a Mammoth demonstrates how de-extinction will redefine conservation's future.

    While these are essential, many young ecologists need to figure out how to actually do research themselves. How to Do Ecology provides nuts-and-bolts advice on how to develop a successful thesis and research program. This book presents different approaches to posing testable ecological questions. In particular, it covers the uses, strengths, and limitations of manipulative experiments in ecology. It will help young ecologists consider meaningful treatments, controls, replication, independence, and randomization in experiments, as well as where to do experiments and how to organize a season of work. This book also presents strategies for analyzing natural patterns, the value of alternative hypotheses, and what to do with negative results.Science is only part of being a successful ecologist. This engagingly written book offers students advice on working with other people and navigating their way through the land mines of research. Findings that don't get communicated are of little value. How to Do Ecology suggests effective ways to communicate information in the form of journal articles, oral presentations, and posters. Finally, it outlines strategies for developing successful grant and research proposals. Numerous checklists, figures, and boxes throughout the book summarize and reinforce the main points. In short, this book makes explicit many of the unspoken assumptions behind doing good research in ecology, and provides an invaluable resource for meaningful conversations among ecologists.

    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.

    For their trail horses, they adopted wild mustangs from the US Bureau of Land Management that were perfectly adapted to the rocky terrain and harsh conditions of desert and mountain travel. A meticulously planned but sometimes unpredictable route brought them face to face with snowpack, downpours, and wildfire; unrelenting heat, raging rivers, and sheer cliffs; jumping cactus, rattlesnakes, and charging bull moose; sickness, injury, and death. But they also experienced a special camaraderie with each other and with the mustangs. Through it all, they had a constant traveling companion—a cameraman, shooting for the documentary film Unbranded. The trip’s inspiration and architect, Ben Masters, is joined here by the three other riders, Ben Thamer, Thomas Glover, and Jonny Fitzsimons; two memorable teachers and horse trainers; and the film’s producers and intrepid cameramen in the telling of this improbable story of adventure and self-discovery.

    Yet residents of compact urban centers, David Owen shows, individually consume less oil, electricity, and water than other Americans. They live in smaller spaces, discard less trash, and, most important of all, spend far less time in automobiles. Residents of Manhattan--the most densely populated place in North America--rank first in public-transit use and last in per-capita greenhouse gas production, and they consume gasoline at a rate that the country as a whole hasn't matched since the mid-1920s, when the most widely owned car in the United States was the Ford Model T. They are also among the only people in the United States for whom walking is still an important means of daily transportation. These achievements are not accidents. Spreading people thinly across the countryside may make them feel green, but it doesn't reduce the damage they do to the environment. In fact, it increases the damage, while also making the problems they cause harder to see and to address. Owen contends that the environmental problem we face, at the current stage of our assault on the world's nonrenewable resources, is not how to make teeming cities more like the pristine countryside. The problem is how to make other settled places more like Manhattan, whose residents presently come closer than any other Americans to meeting environmental goals that all of us, eventually, will have to come to terms with.
