Book Description
Responsible for a high proportion of the world's crop losses, weedstake away food that the world badly needs. They decrease thequality and quantity of vegetable fibers, wool, and hides, andinterfere with fishing, irrigation, hydroelectric power production,and the movement of shipping vessels. In order to recognize thetrue magnitude of the weed problem, and to be better equipped todesign effective weed control methods, it is vital to identify andlearn as much as possible about the many different species of thisdestructive agricultural predator. The culmination of four decades of global research, World Weedspresents comprehensive and up-to-date information on over 100weeds--addressing recent changes in such areas as crop tillagemethods, herbicide use, and agricultural runoff. This monumentalwork, featuring a wealth of original data from the authors,provides extensive coverage of the known biology of each species.Each entry contains a full botanical description, plus importantdetails on habitat requirements and distribution, seed production,ecology, physiology, crop impact, and more. Generously suppliedwith dozens of unique illustrations and species distribution mapscovering over 100 countries, this definitive resource boasts anextensive multilingual index of common names, and a massivebibliography with over 3,000 references to facilitate furtherreading and research. World Weeds is a truly masterful referencethat will be celebrated by weed and crop scientists, botanists, andothers for years to come.

Book Description
Seeds: Ecology, Biogeography, and Evolution of Dormancy and Germination differs from all other books on seed germination. It is an all-encompassing volume that provides a working hypothesis of the ecological and environmental conditions under which various kinds of seed dormancy have developed. It also presents information on the seed germination of more than 3500 species of trees, shrubs, vines and herbaceous species, making this a valuable reference for anyone studying germination. This book delivers information on characteristics of each type of seed dormancy, how each type of dormancy is broken in nature, and what environmental conditions are required for germination after dormancy is broken. It explains how studies should be done to distinguish persistent from transient seed banks, and covers which species should be controlled, propagated, and conserved. Seeds gives the reader insight and guidelines for doing ecologically meaningful studies on the biogeography and evolution of seed dormancy and germination in order to better understand plant reproductive strategies, life history traits, adaptations to habitats, and physiological processes. Evolutionary/phylogenetic origins and relationships of various kinds of seed dormancy A world biogeographical perspective on seed dormancy and germination Ecophysiology of seeds with each type of dormancy Critical evaluation of methodology used in soil seed bank studies Germination ecology of plants with specialized habitat and life cycle types Genetic and maternal preconditioning effects on seed dormancy and germination Guidelines for doing ecologically-meaningful germination studies
