W. John Kress - Böcker

The average kilometer of tropical rainforest is teeming with life; it contains thousands of species of plants and animals. As The Ornaments of Life reveals, many of the most colorful and eye-catching rainforest inhabitants - toucans, monkeys, leaf-nosed bats, and hummingbirds, to name a few - are an important component of the infrastructure that supports life in the forest. These fruit-and-nectar eating birds and mammals pollinate the flowers and disperse the seeds of hundreds of tropical plants, and unlike temperate communities, much of this greenery relies exclusively on animals for reproduction. Synthesizing recent research by ecologists and evolutionary biologists, Theodore H. Fleming and W. John Kress demonstrate the tremendous functional and evolutionary importance of these tropical pollinators and frugivores. They shed light on how these mutually symbiotic relationships evolved and lay out the current conservation status of these essential species. In order to illustrate the striking beauty of these "ornaments" of the rainforest, the authors have included a series of breathtaking color plates and full-color graphs and diagrams.

Natural history has always been the foundation of conservation biology. For centuries, botanists collected specimens in the field to understand plant diversity; now that many habitats are threatened, botanists have turned their focus to conservation, and, increasingly, they look to the collections of museums, herbaria, and botanical gardens for insight on developing informed management programs. Plant Conservation explores the value of these collections in light of contemporary biodiversity studies. Plant Conservation opens with a broad view of plant biodiversity and then considers evolutionary and taxonomic threats and consequences of habitat alteration; specific threats to plant diversity, such as invasive species and global climate change; consequences of plant population decline at the ecological, evolutionary, and taxonomic levels; and, finally, management strategies that protect plant biodiversity from further decline. With a unique perspective on biodiversity and scientific collections, Plant Conservation ultimately emphasizes the role museums and botanical gardens will play in future conservation.

An indispensable illustrated source of information for hundreds of species of North American trees  This authoritative reference on native and non-native trees of North America, by Smithsonian veteran W. John Kress, provides an unprecedented appraisal of more than 325 common species. More than a field guide, it includes  ● over 300 range maps and 3,000 photographs of leaves, flowers, fruits, seeds, and bark;● an in-depth introduction to the biology of trees, their value, structure, evolution, classification, ecology, and conservation;● descriptions of each species, organized by genus and family;● a reflection on the consequences of environmental change on the health of trees, now and in the future;● a presentation, based on the latest technologies, of North American trees in a planetary and evolutionary perspective.  Smithsonian Trees of North America, ten years in the making, marries science and art to provide an insightful and compassionate exploration of the diversity, structure, form, and beauty of trees.

In the great tradition of Darwin's Voyage of the Beagle, this book is a first-person narrative of daunting travel and scientific discovery in the little-known country of Myanmar. Dr. Kress explored many areas in this enigmatic country, surveying its teak forests, bamboo thickets, timber plantations, rivers, and mangroves to document its incredible botanical diversity. Myanmar is one of the great biodiversity hot spots in Asia, but because of its social isolation and reputation for political repression it has been closed to - or avoided by - many scientists. Nevertheless, Dr. Kress was determined to search for and record plants that had not been studied since they were first discovered by Western botanists over a century ago. Among the rarities he came upon was a new species of plant called the weeping goldsmith, a ginger flower whose Burmese name was derived from the legend that the local goldsmiths were reduced to tears because none of their own creations could rival its exquisiteness. Dr. Kress also relates how he came to appreciate the people and culture of Myanmar through an understanding of their flora, natural habitats, and human-dominated environments. Included are fascinating excerpts from his field journals that serve as counterpoints to the accounts of earlier plant explorers. Illustrating the text are some 200 of Dr. Kress's own colour photographs of the incredible plants, people, landscapes, and temples he witnessed in his travels as well as 30 archival images of Burma taken by past explorers. The back matter features an illustrated portfolio of representative native plants. This lively armchair exploration should appeal to a general readership as well as to botanists, conservationists, and environmentalists.
