In this book the geological history of the area is described, as are the forces which have created this unique place. The fascinating marine life is explained in the context of the need to protect its biological diversity.

Johnny Appleseed and the American Orchard illuminates the meaning of Johnny "Appleseed" Chapman’s life and the environmental and cultural significance of the plant he propagated. Creating a startling new portrait of the eccentric apple tree planter, William Kerrigan carefully dissects the oral tradition of the Appleseed myth and draws upon material from archives and local historical societies across New England and the Midwest. The character of Johnny Appleseed stands apart from other frontier heroes like Davy Crockett and Daniel Boone, who employed violence against Native Americans and nature to remake the West. His apple trees, nonetheless, were a central part of the agro-ecological revolution at the heart of that transformation. Yet men like Chapman, who planted trees from seed rather than grafting, ultimately came under assault from agricultural reformers who promoted commercial fruit stock and were determined to extend national markets into the West. Over the course of his life John Chapman was transformed from a colporteur of a new ecological world to a curious relic of a pre-market one. Weaving together the stories of the Old World apple in America and the life and myth of John Chapman, Johnny Appleseed and the American Orchard casts new light on both.

Written by a neurobiologist and a psychologist, this volume presents a new theory of olfactory perception. Drawing on research in neuroscience, physiology, and ethology, Donald A. Wilson and Richard J. Stevenson address the fundamental question of how we navigate through a world of chemical encounters and provide a compelling alternative to the "reception-centric" view of olfaction. The major research challenge in olfaction is determining how the brain discriminates one smell from another. Here, the authors hold that olfaction is generally not a simple physiochemical process, but rather a plastic process that is strongly tied to memory. They find the traditional approach—which involves identifying how particular features of a chemical stimulus are represented in the olfactory system—to be at odds with historical data and with a growing body of neurobiological and psychological evidence that places primary emphasis on synthetic processing and experiential factors. Wilson and Stevenson propose that experience and cortical plasticity not only are important for traditional associative olfactory memory but also play a critical, defining role in odor perception and that current views are insufficient to account for current and past data. The book includes a broad comparative overview of the structure and function of olfactory systems, an exploration into the mechanisms of odor detection and olfactory perception, and a discussion of the implications of the authors' theory. Learning to Smell will serve as an important reference for workers within the field of chemical senses and those interested in sensory processing and perception.

Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about the how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces), a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by numerous illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically accurate book that will serve as both a source book for scientists and for anyone interested in the natural history of the Georgia coast.

The only native palms in Hawai‘i, loulu are among the Islands’ most distinctive plants. Several of the 24 recognized species are rare and endangered and all make handsome and appropriate ornamentals to adorn gardens and landscapes with their dramatic foliage, colorful flower clusters, and conspicuous fruits. In this volume, Donald Hodel shares his expertise on loulu, having traveled extensively throughout Hawai‘i to research and photograph nearly all the species in their native habitat. In the course of his work, he described and named three loulu that were new to science.

Each of the 24 species is treated in detail and this book is handsomely illustrated with more than 200 color photographs that clearly show leaves, flower stalks, fruits, and habitat. Chapters on loulu history, botany, ecology, conservation, uses, and propagation and culture provide essential background information for readers, whatever their level of interest or expertise. In the appendices, they will find a concise summary of loulu, lists of species by island, and an illustrated compendium of exotic, naturalized palms of Hawai‘i and relatives of loulu found throughout the South Pacific.

As interest in growing and conserving native Hawaiian plants surges while their numbers and habitat continue to decline, Loulu: The Hawaiian Palm will be valued as one of the most comprehensive and thoroughly illustrated treatments of these exceptional plants.

In this unique book, Peter S. Ungar tells the story of mammalian teeth from their origin through their evolution to their current diversity. Mammal Teeth traces the evolutionary history of teeth, beginning with the very first mineralized vertebrate structures half a billion years ago. Ungar describes how the simple conical tooth of early vertebrates became the molars, incisors, and other forms we see in mammals today. Evolutionary adaptations changed pointy teeth into flatter ones, with specialized shapes designed to complement the corresponding jaw. Ungar explains tooth structure and function in the context of nutritional needs. The myriad tooth shapes produced by evolution offer different solutions to the fundamental problem of how to squeeze as many nutrients as possible out of foods. The book also highlights Ungar's own path-breaking studies that show how microwear analysis can help us understand ancient diets. The final part of the book provides an in-depth examination of mammalian teeth today, surveying all orders in the class, family by family. Ungar describes some of the more bizarre teeth, such as tusks, and the mammal diversity that accompanies these morphological wonders. Mammal Teeth captures the evolution of mammals, including humans, through the prism of dental change. Synthesizing decades of research, Ungar reveals the interconnections among mammal diet, dentition, and evolution. His book is a must-read for paleontologists, mammalogists, and anthropologists.

This volume comprises original research papers reporting findings collected by participants of the International Workshop on the Mangrove Ecosystem of Deep Bay and the Mai Po Marshes.
