Book Description
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.

Book Description
The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system; role of seed banks in restoration of plant communities; and seed germination in relation to parental effects, pollen competition, local adaption, climate change and karrikinolide in smoke from burning plants. The database for the world biogeography of seed dormancy has been expanded from 3,580 to about 13,600 species. New insights are presented on seed dormancy and germination ecology of species with specialized life cycles or habitat requirements such as orchids, parasitic, aquatics and halophytes. Information from various fields of science has been combined with seed dormancy data to increase our understanding of the evolutionary/phylogenetic origins and relationships of the various kinds of seed dormancy (and nondormancy) and the conditions under which each may have evolved. This comprehensive synthesis of information on the ecology, biogeography and evolution of seeds provides a thorough overview of whole-seed biology that will facilitate and help focus research efforts. Most wide-ranging and thorough account of whole-seed dormancy available Contains information on dormancy and germination of more than 14,000 species from all the continents – even the two angiosperm species native to the Antarctica continent Includes a taxonomic index so researchers can quickly find information on their study organism(s) and Provides a dichotomous key for the kinds of seed dormancy Topics range from fossil evidence of seed dormancy to molecular biology of seed dormancy Much attention is given to the evolution of kinds of seed dormancy Includes chapters on the basics of how to do seed dormancy studies; on special groups of plants, for example orchids, parasites, aquatics, halophytes; and one chapter devoted to soil seed banks Contains a revised, up-dated classification scheme of seed dormancy, including a formula for each kind of dormancy Detailed attention is given to physiological dormancy, the most common kind of dormancy on earth

Book Description
Although global environmental problems created by the disappearance of tropical rain forests are all too well known, the forests themselves--vast in size and rich in diversity--are the least understood of the world's ecosystems. This book presents one researcher's view of Southeast Asia's tropical rainforests, based on a quarter century of fieldwork in a wide range of forest types. Moving from the mangrove of the coastal belt, inland through freshwater and peat swamp forests, to the lowly dipterocarp forests of the heartlands, and up to the montane forests, the author's lively account contains a wealth of detailed observations that effectively communicate the complex natural structure of tropical rain forests while providing the reader with candid first impressions--mud, mosquitoes, and all.

Book Description
The Handbook to the Flora of Ceylon, by Henry Trimen, published more than a hundred years, ago was in its time one of the most comprehensive and outstanding floras available for any tropical area. Updated and expanded first in 1931 by A.H.G. Alston and most recently under the auspices of the Smithsonian Institution, the Ceylon Department of Agriculture, and the University of Ceylon, the handbook now comprises 14 volumes, many of which are once again available through this publisher. This volume is a comprehensive index to those 14 volumes, with entries listed by scientific name, English name, Sinhala name and Tamil name.

Book Description
An important overview of the state of the art in naturally occurring antimycotics! Here is a comprehensive and innovative examination of the antimycotic potential of essential plant oils and extracts against fungal infections affecting humans, animals, plants, and foodstuffs. Plant-Derived Antimycotics emphasizes the antimycotic activity of plants found in Central America, India, Nepal, Fiji, and China--areas rich in phyto-diversity and traditional botanical/medical knowledge. From editor M.K. Rai: “Since the inception of human civilization men have been using herbs against various mycotic infections. In the recent past, several antimycotic agents have been introduced into the market due to their rapid curative properties. Still, the quest for new antifungal agents of a fungicidal rather than fungistatic nature continues. Furthermore, there has been a dramatic increase in the new spectrum of fungal infections known as opportunistic fungal pathogens. Consequently, plant-derived antimycotics are gaining importance, being natural, cheaper, safer, eco-friendly, and within the reach of the common man.” With a distinguished list of contributors from around the world, Plant-Derived Antimycotics explores: antifungal compounds that strengthen plant-defense systems traditional herbs that have revealed their antifungal properties newer, faster methods of screening and evaluating antifungal drugs natural antimycotics derived from plants in Croatia, South America, South Africa, China, India, and Fiji the mechanism of herbal antimycotic action the diversity of antimycotic efficacy in Asteraceous and Meliaceous plants new bioactive antifungal molecules Plant-Derived Antimycotics is an essential reference for pharmacologists, microbiologists, clinical mycologists, oncologists, immunologists, drug manufacturers, botanists and ethnobotanists, phytochemists, herbalists, and everyone searching for a natural remedy for the new spectrum of opportunistic fungal infections generated by the immunocompromising difficulties encountered by AIDS and cancer patients. Color illustrations, photographs, charts, tables, and graphs make the information easier to absorb and understand.
