Humans have feared them for centuries, long considering them the assassins and pariahs of the natural world.Now, in Venomous, the biologist Christie Wilcox investigates and illuminates the animals of our nightmares, arguing that they hold the keys to a deeper understanding of evolution, adaptation, and immunity. She reveals just how venoms function and what they do to the human body. With Wilcox as our guide, we encounter a jellyfish with tentacles covered in stinging cells that can kill humans in minutes; a two-inch caterpillar with toxic bristles that trigger hemorrhaging; and a stunning blue-ringed octopus capable of inducing total paralysis. How do these animals go about their deadly work? How did they develop such intricate, potent toxins? Wilcox takes us around the world and down to the cellular level to find out.Throughout her journey, Wilcox meets the intrepid scientists who risk their lives studying these lethal beasts, as well as “self-immunizers” who deliberately expose themselves to snakebites. Along the way, she puts her own life on the line, narrowly avoiding being envenomated herself. Drawing on her own research, Wilcox explains how venom scientists are untangling the mechanisms of some of our most devastating diseases, and reports on pharmacologists who are already exploiting venoms to produce lifesaving drugs. We discover that venomous creatures are in fact keystone species that play crucial roles in their ecosystems and ours—and for this alone, they ought to be protected and appreciated.Thrilling and surprising at every turn, Venomous will change everything you thought you knew about the planet’s most dangerous animals.

    But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity.There is an unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. In many parts of the world, habitat destruction has been so extensive that local wildlife is in crisis and may be headed toward extinction.Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and the new paperback edition—with an expanded resource section and updated photos—will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.

    Descriptions of each print is written by Dr. Colin Harrison and Cyril Walker, scientific officers of the British Museum of Natural History.

    Inspired by her own feline's instinct to hunt and supported by her studies abroad, Thomas examines the life actions, as well as the similarities and differences of these majestic creatures. Lions, tigers, pumas and housecats: Her observations shed light on their social lives, thought processes, eating habits, and communication techniques, and reveal how they survive and coexist with each other and with humans.

    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.

    This art form has been developed by Rick Roberts and Maria Thomas. What I love most about this art form is that all the patterns are based on simple lines, circles and shapes. Anyone can do it.

    We all have one, but most of us will never see one. The heart surgeon now has that privilege but, for centuries, the heart was out of reach even for surgeons. So when a surgeon nowadays opens up a ribcage and mends a heart, it remains something of a miracle, even if, to some, it is merely plumbing. As with plumbers, the quality of surgeons’ work varies. As with plumbers, surgeons’ opinion of their own prowess and their own attitude to risk are not always reliable. Measurement is key. We’ve had a century of effective evidence-based medicine. We’ve had barely a decade of thorough monitoring of clinical outcomes. Thanks to the ground-breaking risk modelling of pioneering surgeons like Samer Nashef, we at last know how to judge whether an operation is in a patient’s best interest, which hospital and surgeon would be best for that operation, when it might best be performed and what the exact level of risk is. We have at last made what is important in surgery measurable. But how should surgeons, and their patients, use these newfound insights? Ever since his days as a medical student, Samer Nashef has challenged the medical profession to be more open and more accurate about the success of surgical procedures, for the sake of the patients. In The Naked Surgeon, he unclothes his own profession to demonstrate to his reader (and prospective patient) many revelations, such as the paradox at the heart of the cardiac surgeon’s craft: the more an operation is likely to kill you, the better it is for you. And he does so with absolute clarity, fluency and not a little wit.

    

    Heinrich has spent a lifetime observing the natural world, and now he shares his vast knowledge and reflections on the trees of the Northeast woods and the rhythms of their seasons.From the DNA contained in an apple seed to the great choiring branches far beyond a young boy's reach, Heinrich explores a natural world in scientific and personal terms. Heinrich is a scientist, but his words speak with the power and subtle grace of a poet. He uses this gift, and his intimate knowledge of his 300 acres of Maine forest, to expose the forest's rhythms, and in doing so, illustrates the vital but tenuous link among man, trees, birds, insects, and all the creatures of the forest. Thanks to Bernd Heinrich, readers will finally see the forest and the trees.

    Seeking to address the various challenges of off-camera lighting, professional photographers and advanced amateurs alike will find a range of confidence-building instruction, beginning with basic how’s and why’s of lighting for creative effect, the types of equipment available and instruction about their proper use, clear definitions of various technical concepts such as managing shutter speed and controlling flash exposure, using ambient light as well as natural sunlight during a shoot, and incorporating off-camera flash into a portrait session. Concluding this lesson plan is a look at five different real-life photo sessions, each employing a different flash technique. Here, photographers get a deeper understanding of each concept put into practice, marrying the elements of lighting with the natural elements presented by the shoot.

    He had a talent for drawing and an interest in birds, and he would spend the next thirty-five years traveling to the remotest regions of his new country–often alone and on foot–to render his avian subjects on paper. The works of art he created gave the world its idea of America. They gave America its idea of itself. Here Richard Rhodes vividly depicts Audubon’s life and career: his epic wanderings; his quest to portray birds in a lifelike way; his long, anguished separations from his adored wife; his ambivalent witness to the vanishing of the wilderness. John James Audubon: The Making of an American is a magnificent achievement.

    Yet The Origin of Species (1859) is also a humane and inspirational vision of ecological interrelatedness, revealing the complex mutual interdependencies between animal and plant life, climate and physical environment, and—by implication—within the human world. Written for the general reader, in a style which combines the rigour of science with the subtlety of literature, The Origin of Species remains one of the founding documents of the modern age.
