Cactus and Succulent Plants

Pages : 214
Book Description
Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.

Book Description
"There is nothing in the world like this book. It should be in every library and on the bookshelves of all those interested in cacti. The book will be an important resource for plant physiology, agronomy, and horticulture classes at both the undergraduate and graduate level."—Bruce Smith, Brigham Young University "Cacti: Biology and Uses is a landmark publication of one of the world's most unique group of plants. Park Nobel, a leading authority on succulent plants, has assembled a collection of contributions that spans a wide range of issues extending from basic systematics, anatomy, physiology and ecology to considerations of conservation and human uses of this diverse group of plants. This nicely-produced and well-illustrated volume provides a resource that will be of great use to a wide range of scientists, practitioners, and enthusiasts of this plant group."—Harold Mooney, Paul S. Achilles Professor of Environmental Biology, Stanford University
Caryophyllales
Author: H.D. BehnkePublisher: Springer Science & Business Media

Category : Science
Languages : fr
Pages : 339
Book Description
The Caryophyllales are one of the few higher taxa of the flowering plants ofwhich the size and delimitation against other taxa is undisputed. However, their derivation from other taxa and the evolution of families within this order in unsettled. "Systematics and Evolution of the Caryophyllales" reviews the important characters of this taxon emphasizing their contribution and influence towards a new proposal for both the putative origin of the order and the classification of its families. New results in molecular genetics, phytochemistry, ultrastructure, and morphology are provided and discussed in relation to both the classical and molecular systematics of the order. In addition, characters like betalains and sieve-element plastids, which have played a major role in shaping the size of the order, and others like DNA-data or flower morphologythat can be useful to discuss the position of the Caryophyllales within higher plants are critically evaluated.
