Our knowledge of the ecology of tropical rain-forest trees is limited, yet a good understanding of the trees is essential to unravelling the workings of the forest itself. This book aims to summarise contemporary understanding of the ecology of tropical rain-forest trees, with particular emphasis on comparative ecology.
Coupled with biomechanical data, organic geochemistry and cladistic analyses utilizing abundant genetic data, scientific studies are revealing new facets of how plants have evolved over time. This collection of papers examines these early stages of plant physiology evolution by describing the initial physiological adaptations necessary for survival as upright structures in a dry, terrestrial environment. The Evolution of Plant Physiology also encompasses physiology in its broadest sense to include biochemistry, histology, mechanics, development, growth, reproduction and with an emphasis on the interplay between physiology, development and plant evolution. Contributions from leading neo- and palaeo-botanists from the Linnean Society Focus on how evolution shaped photosynthesis, respiration, reproduction and metabolism. Coverage of the effects of specific evolutionary forces -- variations in water and nutrient availability, grazing pressure, and other environmental variables
Over the past two decades U.S. lumber imports from the tropics have increased fourfold. Plywood trade, mostly from Asian sources, has soared forty-fold and now equals our domestic production. Log imports, though, have decreased drastically from about 100 million board feet (log scale) in the 1950's to 30 million currently. Much of the world timber trade now is in the form of processed material. Many more tropical wood species and species groupings are being made available to U.S. processors. Most of these have been well known for many years on the European markets. This interest in supplemental supplies from overseas is in both softwoods and hardwoods. An extensive foreign literature has described the properties and uses of tropical woods, but much of it is no longer readily available. In this country the U.S. Forest Products Laboratory, over the years, issued 'Information Leaflets' or 'Foreign Wood Series' reports on some species of importance. But many of these are now out of print. The most recent comprehensive document, 'Properties of Imported Tropical Woods, ' contained a description of about 100 tropical genera.
