With extensive treatment of the heart of epidemiology-from study designs to descriptive epidemiology to quantitative measures-this reader-friendly text is accessible and interesting to a wide range of beginning students in all health-related disciplines. A unique focus is given to real-world applications of epidemiology and the development of skills that students can apply in subsequent course work and in the field. The text is also accompanied by a complete package of instructor and student resources available through a companion Web site.

    In the oceans, though, living space has both vertical and horizontal dimensions: with an average depth of 3800 meters, the oceans offer 99% of the space on Earth where life can develop. And the deep sea, which has been immersed in total darkness since the dawn of time, occupies 85% of ocean space, forming the planet’s largest habitat.  Yet these depths abound with mystery. The deep sea is mostly uncharted—only about 5 percent of the seafloor has been mapped with any reasonable degree of detail—and we know very little about the creatures that call it home. Current estimates about the number of species yet to be found vary between ten and thirty million.  The deep sea no longer has anything to prove; it is without doubt Earth’s largest reservoir of life.Combining the latest scientific discoveries with astonishing color imagery, The Deep takes readers on a voyage into the darkest realms of the ocean. Revealing nature’s oddest and most mesmerizing creatures in crystalline detail, The Deep features more than two hundred color photographs of terrifying sea monsters, living fossils, and ethereal bioluminescent creatures, some photographed here for the very first time. Accompanying these breathtaking photographs are contributions from some of the world’s most respected researchers that examine the biology of deep-sea organisms, the ecology of deep-sea habitats, and the history of deep-sea exploration.An unforgettable visual and scientific tour of the teeming abyss, The Deep celebrates the incredible diversity of life on Earth and will captivate anyone intrigued by the unseen—and unimaginable—creatures of the deep sea.

    Next, he examines the three critiques that currently challenge this classic Darwinian edifice: that selection operates on multiple levels, from the gene to the group; that evolution proceeds by a variety of mechanisms, not just natural selection; and that causes operating at broader scales, including catastrophes, have figured prominently in the course of evolution.Then, in a stunning tour de force that will likely stimulate discussion and debate for decades, Gould proposes his own system for integrating these classical commitments and contemporary critiques into a new structure of evolutionary thought.In 2001 the Library of Congress named Stephen Jay Gould one of America's eighty-three Living Legends--people who embody the quintessentially American ideal of individual creativity, conviction, dedication, and exuberance. Each of these qualities finds full expression in this peerless work, the likes of which the scientific world has not seen--and may not see again--for well over a century.

    Descriptive text includes measurements, diagnostic details, and information on habitat, range, feeding habits, sounds or songs, flight period, web construction, life cycle, behaviors, folklore, and environmental impact. An illustrated key to the insect orders and detailed drawings of the parts of insects, spiders, and butterflies supplement this extensive coverage.

    Discover the vital aspects of various species, how they feed, mate, and learn about their natural environment.

    Based on vegetative rather than floral characteristics, this practical guide gives anyone who works with plants the ability to identify weeds before they flower.- A dichotomous key to all the species described in the book is designed to narrow the choices to a few possible species. Identification can then be confirmed by reading the descriptions of the species and comparing a specimen with the drawings and photographs.- A fold-out grass identification table provides diagnostic information for weedy grasses in an easy-to-use tabular key.- Specimens with unusual vegetative characteristics, such as thorns, square stems, whorled leaves, or milky sap, can be rapidly identified using the shortcut identification table.The first comprehensive weed identification manual available for the Northeast, this book will facilitate appropriate weed management strategy in any horticultural or agronomic cropping system and will also serve home gardeners and landscape managers, as well as pest management specialists and allergists.

    The Birder's Handbook is the first of its kind: a portable library of fascinating information not included in your identification guide. For each of the 646 species of birds that breed in North America, The Birder's Handbook will tell you at a glance: * Where the bird nests, and which sex(es) build(s) the nest;* How many eggs the bird lays, what they look like, which patent incubates and for how long, and how the young are cared for;* Food preferences and foraging habits.You will also find information about displays and mating, wintering, conservation status, and much more. In addition, The Birder's Handbook contains some 250 short essays covering all aspects of avian natural history.

    More than 2,000 close-up color photographs by leading nature photographers reveal the field marks that distinguish each creature, and the clear and concise text that accompanies each image describes the range, habitat, life cycle, and behavior. Budding entomologists will be inspired to explore further with the detailed information on starting a collection, planting an arthropod garden, keeping insects and spiders in captivity, and learning the techniques of macro photography. The unique waterproof cover makes it ideal for use outdoors.

    Through dramatic graphics and age-appropriate text, this authoritative volume charts the discovery of all the main types of dinosaurs and reveals the latest details on how these creatures most likely looked, behaved, defended themselves, found food, cared for their young, and interacted.
