Amateur and expert alike can quickly and accurately identify almost any wildflower using Lawrence Newcomb's system, which is based on natural structural features that are easily visible even to the untrained eye. Every time you see an unknown plant, ask yourself the same five questions (related to the type of plant and the structure of its petals and leaves), and you will be directed to the page on which the plant can be found. Beautiful illustrations make confirmation easy.

    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.

    Mt. Lockley, who observed rabbits in Wales over a 5 year period, shows that they have a complex community life little understood by the world in general. These vegetarian creatures posses both dignity and 'animality'; psychological factors play as large a part in shaping their lives as they do in ours. One finds, too, that their reputation for promiscuity and wanton reproduction is really undeserved. Lockley built an artificial warren with glass sides and several tracts of natural habitat-an open plain, a woodlot, a lushly vegetated savannah were enclosed and arranged for maximum ease of observation with minimum interference. This controlled rabbit colony was observed every day and night in every season and in all kinds of weather. In Lockley's account, rabbits emerge with characteristics and personalities of their own. The nicknames he gives them (Weary Willie, Timid Timothy, Bold Benjamin, for example) in no way lessen the objective and scientific accuracy of his findings. In fact, this touch of individuality reinforces the observation that rabbits are creatures with interests, wills, and preferences of their own. Female conservatism, scent setting or 'chinning' by dominant males, the ability of the female to absorb her fertilized embryo, the stress of subordinate status...and more, are revealed here.

    Who would have guessed that all of our sexual and social behavior, and even our physical appearance, could be attributed to what our tiny unseen reproductive cells are doing? But that's Quirk's thesis in this highly entertaining book from an Average Guy that's a fun read full of a-ha! moments for scientists and civilians alike. Learn facts about cheating you'll never see on "Jerry Springer," like how unfaithful females actually change the biology of their mates. Discover why most sperm couldn't care less if they never saw an egg, what makes men yell "woo!" in a feminine falsetto--very similar to the mating cry of the Siamang gibbon--and, most important, the surprising answer on what to wear to attract that alpha mate.

    Whales: An Illustrated Celebration explores the most interesting and illuminating facts about these marine mammals, from the enormous blue whale (which has a heart the size of a car!) to the Amazon river dolphin (which is pink!). Gorgeously illustrated with full-color art on every page, this giftable guide delves into cetaceans' mysterious evolution (from land to water mammals), their place in mythology, and their ecology, habitats, and behaviors (such as singing, fluking, beaching, bubble feeding, and more). Perfect for nature and animal lovers from eight to eighty, Whales also covers the current state of wild and captive cetaceans worldwide, why we should care, and what we can do to help our beautiful marine mammal friends.

    Today there are three cats for every dog on the planet, and yet cats remain more mysterious, even to their most adoring owners. Unlike dogs, cats evolved as solitary hunters, and, while many have learned to live alongside humans and even feel affection for us, they still don’t quite get us” the way dogs do, and perhaps they never will. But cats have rich emotional lives that we need to respect and understand if they are to thrive in our company.In Cat Sense, renowned anthrozoologist John Bradshaw takes us further into the mind of the domestic cat than ever before, using cutting-edge scientific research to dispel the myths and explain the true nature of our feline friends. Tracing the cat’s evolution from lone predator to domesticated companion, Bradshaw shows that although cats and humans have been living together for at least eight thousand years, cats remain independent, predatory, and wary of contact with their own kind, qualities that often clash with our modern lifestyles. Cats still have three out of four paws firmly planted in the wild, and within only a few generations can easily revert back to the independent way of life that was the exclusive preserve of their predecessors some 10,000 years ago. Cats are astonishingly flexible, and given the right environment they can adapt to a life of domesticity with their owners—but to continue do so, they will increasingly need our help. If we’re to live in harmony with our cats, Bradshaw explains, we first need to understand their inherited quirks: understanding their body language, keeping their environments—however small—sufficiently interesting, and becoming more proactive in managing both their natural hunting instincts and their relationships with other cats.A must-read for any cat lover, Cat Sense offers humane, penetrating insights about the domestic cat that challenge our most basic assumptions and promise to dramatically improve our pets’ lives—and ours.

    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.

    Darwin wondered why these birds were confined to remote islands at the tip of South America, sensing a larger story, but he set this mystery aside and never returned to it. Almost two hundred years later, Jonathan Meiburg takes up this chase. He takes us through South America, from the fog-bound coasts of Tierra del Fuego to the tropical forests of Guyana, in search of these birds: striated caracaras, which still exist, though they're very rare. He reveals the wild, fascinating story of their history, origins, and possible futures. And along the way, he draws us into the life and work of William Henry Hudson, the Victorian writer and naturalist who championed caracaras as an unsung wonder of the natural world, and to falconry parks in the English countryside, where captive caracaras perform incredible feats of memory and problem-solving. A Most Remarkable Creature is a hybrid of science writing, travelogue, and biography, as generous and accessible as it is sophisticated, and absolutely riveting.
