Crop wild relatives (CWR) are plant species which are more or less closely related to crops. They are a vital resource by providing a pool of genetic variation that can be used in breeding new and better adapted varieties of crops that are resistant to stress, disease, drought and other factors. They will be increasingly important in allowing crops to adapt to the impacts of climate, thus safeguarding future agricultural production. Until recently, the main conservation strategy adopted for CWR has been ex situ - through the maintenance of samples as seed or vegetative material in various kinds of genebank or other facilities. Now the need to conserve CWR in their natural surroundings (in si...
Flowering plant families of the world is the successor to Flowering plants of the world (1978).
The survival of the Earth's biological resources is under threat from rapidly expanding human populations that are degrading the environment at an accelerating rate. Despite the increased awareness of the importance of biological diversity, the scientific foundations on which to plan conservation and development policies are still being developed. The Global Biodiversity Assessment represents an unparalleled attempt to provide an independent scientific analysis of the current issues. It assesses the present state of knowledge, identifies gaps in understanding and draws attention to those issues where scientists have reached a consensus as well as those where uncertainty has led to conflicting viewpoints and a need for further research. The Assessment provides an unprecedented source of information for decision-makers, officials, scientists and others interested in the future of the planet.

"This multifarious volume does a splendid job of reflecting the breadth and depth of fundamental questions about the methods of systematics and biogeography, from the practical applications of conservation biology to issues of wide interest to evolutionary biologists."--Dr. Norman I. Platnick, American Museum of Natural History "A fun and informative volume that everyone interested in the subject will enjoy. This book is full of important discussions on Botany, Cladistics, and Biogeography."--Vicki Funk, National Museum of Natural History, Smithsonian Institution "The Branching Of A Paradigm is the intriguing theme of this volume on the myriad of ways cladistics has impacted modern biology. Surprises from floristics to recent thoughts on epistemology await the reader."--Dennis Stevenson, New York Botanical Garden
