The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

    His powerful message, conveyed with humor, compassion, and art: to know these animals is to save them.Sartore intends to photograph every animal in captivity in the world. He is circling the globe, visiting zoos and wildlife rescue centers to create studio portraits of 12,000 species, with an emphasis on those facing extinction. He has photographed more than 6,000 already and now, thanks to a multi-year partnership with National Geographic, he may reach his goal. This book showcases his animal portraits: from tiny to mammoth, from the Florida grasshopper sparrow to the greater one-horned rhinoceros. Paired with the eloquent prose of veteran wildlife writer Douglas Chadwick, this book presents a thought-provoking argument for saving all the species of our planet.

    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.

    They spread rapidly, even in such seemingly harmless places as high school locker rooms, where they infect young athletes. Throughout the world, many more people are dying from these infections. Astoundingly, as antibiotic resistant infections are skyrocketing in incidence—creating a critical need for new antibiotics—research and development of new antibiotics has ground to a screeching halt!In Rising Plague, Dr. Brad Spellberg—an infectious diseases specialist and member of a national task force charged with attacking antibiotic resistant infections—tells the story of this potentially grave public health crisis. The author shares true and very moving patient stories to emphasize the terrible frustration he and his colleagues have experienced while attempting to treat untreatable infections, not to mention the heart-break and tragedy that many of these patients’ families had to endure. Dr. Spellberg corrects the nearly universal misperception that physician misuse of antibiotics and "dirty hospitals" are responsible for causing antibiotic-resistant infections. He explains the true causes of antibiotic resistance and of the virtual collapse of antibiotic research and development. Most important, he advocates ways to reverse this dire trend and instead bolster the production of desperately needed new and effective antibiotics. He also warns against complacency induced by the decades-old assumption that some miracle drug will always be available to ensure the continuation of our "antibiotic era." If we do nothing, we run the risk of inviting a bleak future when infectious diseases will once again reign supreme. Then many of the medical breakthroughs that we now take for granted—from routine surgery and organ transplants to intensive care and battlefield medicine—might all be threatened.This crucial and timely book is lucidly written in terms that everyone can understand. It issues a call to action, explaining how, through a strong and concerted effort, we can all help prevent this nightmare scenario from happening. By following this courageous doctor’s recommendations, we can assure that magic bullets will be there for our families and us in the future.

    What exactly is the meaning of all those stone walls in the middle of the forest? Why do beech and birch trees have smooth bark when the bark of all other northern species is rough? How do you tell the age of a beaver pond and determine if beavers still live there? Why are pine trees dominant in one patch of forest and maples in another? What happened to the American chestnut? Turn to this book for the answers, and no walk in the woods will ever be the same.

    Recent, massive blooms of billions of jellyfish have clogged power plants, decimated fisheries, and caused millions of dollars of damage. Driven by questions about how overfishing, coastal development, and climate change were contributing to a jellyfish population explosion, Juli embarked on a scientific odyssey. She traveled the globe to meet the biologists who devote their careers to jellies, hitched rides on Japanese fishing boats to see giant jellyfish in the wild, raised jellyfish in her dining room, and throughout it all marveled at the complexity of these alluring and ominous biological wonders.

    It explains how it was a premeditated, orchestrated deception, using science to impose a political agenda. It fooled a majority including most scientists. They assumed that other scientists would not produce science for a political agenda. German Physicist and meteorologist Klaus-Eckart Puls finally decided to look for himself. Here is what he discovered. Ten years ago I simply parroted what the IPCC told us. One day I started checking the facts and data—first I started with a sense of doubt but then I became outraged when I discovered that much of what the IPCC and the media were telling us was sheer nonsense and was not even supported by any scientific facts and measurements. To this day I still feel shame that as a scientist I made presentations of their science without first checking it.…scientifically it is sheer absurdity to think we can get a nice climate by turning a CO2 adjustment knob. This book uses the same approach used in investigative journalism. It examines the Who, What, Where, When, Why, and How.

    He is also the Head Teaching Fellow for the most popular course at Harvard, “Positive Psychology,” which is taken by more than 1,000 students per semester and led by Professor Tal Ben-Shahar.  Shawn received his B.A. in English from Harvard and a Master’s from Harvard Divinity School in Christian and Buddhist Ethics. Part of his interest in positive psychology stems from a troubling fact: studies have shown that many of Harvard’s undergraduates suffer from depression at some point in their college careers.

    It uses a taxonomic approach for the study of pathogens.

    Just as human cultures pass on languages and turns of phrase, tastes in food (and in how it is acquired), and modes of dress, could whales and dolphins have developed a culture of their very own? Unequivocally: yes. In The Cultural Lives of Whales and Dolphins, cetacean biologists Hal Whitehead, who has spent much of his life on the ocean trying to understand whales, and Luke Rendell, whose research focuses on the evolution of social learning, open an astounding porthole onto the fascinating culture beneath the waves. As Whitehead and Rendell show, cetacean culture and its transmission are shaped by a blend of adaptations, innate sociality, and the unique environment in which whales and dolphins live: a watery world in which a hundred-and-fifty-ton blue whale can move with utter grace, and where the vertical expanse is as vital, and almost as vast, as the horizontal. Drawing on their own research as well as a scientific literature as immense as the sea—including evolutionary biology, animal behavior, ecology, anthropology, psychology, and neuroscience—Whitehead and Rendell dive into realms both humbling and enlightening as they seek to define what cetacean culture is, why it exists, and what it means for the future of whales and dolphins. And, ultimately, what it means for our future, as well.

    Learning all the tongue twisting names, picking favorites based on ferocity, armor, or sheer size. For many kids this love of ‘terrible lizards’ fizzles out at some point between starting and leaving primary school. All those fancy names slowly forgotten, no longer any need for a favorite.For all those child dino fanatics who didn’t grow up to become paleontologists, dinosaurs seem like something out of mythology. They are dragons, pictures in books, abstract, other, extinct.They are at the same time familiar and mysterious.
