The decade since the publication of the third edition of this volume has been an era of great progress in biology in general and the plant sciences in particular. This is especially true with the advancements brought on by the sequencing of whole genomes of model organisms and the development of "omics" techniques. This fourth edition of Plant Roots: The Hidden Half reflects these developments that have transformed not only the field of biology, but also the many facets of root science. Highlights of this new edition include: The basics of root research and their evolution and role in the global context of soil development and atmosphere composition New understandings about roots gained in the post-genomic era, for example, how the development of roots became possible, and the genetic basis required for this to occur The mechanisms that determine root structure, with chapters on cellular patterning, lateral root and vascular development, the molecular basis of adventitious roots, and other topics Plant hormone action and signaling pathways that control root development, including new chapters on strigolactones and brassinosteroids Soil resource acquisition from agricultural and ecological perspectives Root response to stress, with chapters that address the impact of the genomic revolution on this topic Root-rhizosphere interactions, from beneficial microorganisms to detrimental nematodes Modern research techniques for the field and the lab Each chapter not only presents a clear summation of the topic under discussion, but also includes a vision of what is to be expected in the years to come. The wide coverage of themes in this volume continues the tradition that makes this work recognized as a fundamental source of information for root scientists at all levels.

In this final collection of Anne Morrow Lindbergh’s letters and journals, we mark Mrs. Lindbergh’s progress as she navigated a remarkable life and a remarkable century with enthusiasm and delight, humor and wit, sorrow and bewilderment, but above all devoted to finding the essential truth in life’s experiences through a hard-won spirituality and a passion for literature. Between the inevitable squalls of life with her beloved but elusive husband, the aviator Charles A. Lindbergh, she shepherded their five children through whooping cough, horned toads, fiancés, the Vietnam War, and their own personal tragedies. She researched and wrote books and articles on issues ranging from the condition of Europe after World War II to the meaning of marriage to the launch of Apollo 8. She published one of the most beloved books of inspiration of all time, Gift from the Sea. She left penetrating accounts of meetings with such luminaries as John and Jacqueline Kennedy, Thornton Wilder, Enrico Fermi, Leland and Slim Hayward, and the Frank Lloyd Wrights. And she found time to compose extraordinarily insightful and moving letters of consolation to friends and to others whose losses touched her deeply. Against Wind and Tide makes us privy to the demons that plagued this fairy-tale bride, and introduces us to some of the people—men as well as women—who provided solace as she braved the tides of time and aging, war and politics, birth and death. Here is an eloquent and often startling collection of writings from one of the most admired women of our time. (With 8 pages of black-and-white photographs.)

Against Wind and Tide tells the story of African American's battle against the American Colonization Society (ACS), founded in 1816 with the intention to return free blacks to its colony Liberia. Although ACS members considered free black colonization in Africa a benevolent enterprise, most black leaders rejected the ACS, fearing that the organization sought forced removal. As Ousmane K. Power-Greene's story shows, these African American anticolonizationists did not believe Liberia would ever be a true "black American homeland." In this study of anticolonization agitation, Power-Greene draws on newspapers, meeting minutes, and letters to explore the concerted effort on the part of nineteenth century black activists, community leaders, and spokespersons to challenge the American Colonization Society's attempt to make colonization of free blacks federal policy. The ACS insisted the plan embodied empowerment. The United States, they argued, would never accept free blacks as citizens, and the only solution to the status of free blacks was to create an autonomous nation that would fundamentally reject racism at its core. But the activists and reformers on the opposite side believed that the colonization movement was itself deeply racist and in fact one of the greatest obstacles for African Americans to gain citizenship in the United States. Power-Greene synthesizes debates about colonization and emigration, situating this complex and enduring issue into an ever broader conversation about nation building and identity formation in the Atlantic world.

Towns and villages are sometimes viewed as minor, even quaint, spots, whereas this book boldly reconceptualizes these places as important dynamic environmental 'hotspots'. Multitudes of towns and villages with nearly half the world's population characterize perhaps half the global land surface. The book's pages feature ecological patterns, processes, and change, as well as human dimensions, both within towns and in strong connections and effects on surrounding agricultural land, forest land, and arid land. Towns, small to large, and villages are examined with spatial and cultural lenses. Ecological dimensions - water, soil and air systems, together with habitats, plants, wildlife and biodiversity - are highlighted. A concluding section presents concepts for making better towns and better land. From a pioneer in both landscape ecology and urban ecology, this highly international town ecology book opens an important frontier for researchers, students, professors, and professionals including environmental, town, and conservation planners.
