Conifers are one of the world's most important resources of timber. If managed wisely and used sustainably, these resources will provide wood for a multitude of purposes, virtually indefinitely. Additional products include resins and their derivatives, and even medicinal extracts--for example taxol now used in the treatment of cancer. Conifers occur on all continents except Antarctica. Of the 630 species, 355 are listed as of conservation concern, with 200, or 25 of species, threatened with extinction. Although exploitation of these resources is as old as civilization, this century has seen a dramatic increase in the exploitation of timber resources. This action plan assess conifer diversity and its threats. It is unique among IUCN's Plant Action Plans so far published, in that it gives the complete global red list of conifers using the 1994 IUCN Red List Categories and criteria. Data is analyzed to identify "conifer hot spots", where conservation should be a priority, and a short-list of threatened species is prioritized.

Phylogeography of California examines the evolution of a variety of taxaÑancient and recent, native and migratoryÑto elucidate evolutionary events both major and minor that shaped the distribution, radiation, and speciation of the biota of California. The book also interprets evolutionary history in a geological context and reviews new and emerging phylogeographic patterns. Focusing on a region that is defined by physical and political boundaries, Kristina A. Schierenbeck provides a phylogeographic survey of CaliforniaÕs diverse flora and fauna according to their major organismal groups. Life history and ecological characteristics, which play prominent roles in the various outcomes for respective clades, are also considered throughout the work. Supporting scholars and researchers who study evolutionary diversification, the book analyzes research that helps assess one of the major challenges in phylogeographic studies: understanding changes in population structures shaped by geological and geographical processes. California is one of only twenty-five acknowledged biological hotspots worldwide, and the phylogeographic history of the state can be extrapolated to study other regions in western North America. Further consideration is given to implications for conservation, recommendations concerning the biogeographic provinces that roughly define the state of California, and predictions related to climate change.

In the twentieth-century struggle for racial equality, there was perhaps no setting more fraught and contentious than the public schools of the American south. In Prince Edward County, Virginia, in 1951, a student strike for better school facilities became part of the NAACP legal campaign for school desegregation. That step ultimately brought this rural, agricultural county to the Supreme Court of the United States as one of five consolidated cases in the historic 1954 ruling, Brown v. Board of Education. Unique among those cases, Prince Edward County took the extreme stance of closing its public school system entirely rather than comply with the desegregation ruling of the Court. The schools were closed for five years, from 1959 to 1964, until the Supreme Court ruling in Griffin v. County School Board of Prince Edward County ordered the restoration of public education in the county. This historical anthology brings together court cases, government documents, personal and scholarly writings, speeches, and journalism to represent the diverse voices and viewpoints of the battle in Prince Edward County for—and against—educational equality. Providing historical context and contemporary analysis, this book offers a new perspective of a largely overlooked episode and seeks to help place the struggle for public education in Prince Edward County into its proper place in the civil rights era.

"This completely new edition of Terrestrial Vegetation of California clearly documents the extraordinary complexity and richness of the plant communities and of the state and the forces that shape them. This volume is a storehouse of information of value to anyone concerned with meeting the challenge of understanding, managing or conserving these unique plant communities under the growing threats of climate change, biological invasions and development."—Harold Mooney, Professor of Environmental Biology, Stanford University "The plants of California are under threat like never before. Traditional pressures of development and invasive species have been joined by a newly-recognized threat: human-caused climate change. It is essential that we thoroughly understand current plant community dynamics in order to have a hope of conserving them. This book represents an important, well-timed advance in knowledge of the vegetation of this diverse state and is an essential resource for professionals, students, and the general public alike."—Brent Mishler, Director of the University & Jepson Herbaria and Professor of Integrative Biology, University of California, Berkeley
