Book Description
A comprehensive review of the honeybees of Africa on a subspecies as well as by country basis. Includes an updated multivariate analysis of the subspecies based on the merger of the Ruttner database (Oberursel) and that of Hepburn & Radloff (Grahamstown) for nearly 20,000 bees. Special emphasis is placed on natural zones of hybridisation and introgression of different populations; seasonal cycles of development in different ecological-climatological zones of the continent; swarming, migration and absconding; and an analysis of the bee flora of the continent. The text is supplemented by tables containing quantitative data on all aspects of honeybee biology, and by continental and regional maps.

Book Description
Birds in the Ancient World from A to Z gathers together the ancient information available, listing all the names that ancient Greeks gave their birds and all their descriptions and analyses. W. Geoffrey Arnott identifies as many of them as possible in the light of modern ornithological studies. The ancient Greek bird names are transliterated into English script, and all that the ancients said about birds is presented in English. This book is accordingly the first complete discussion of ancient bird names that will be accessible to readers without ancient Greek. The only large-scale examination of ancient birds for seventy years, the book has an exhaustive bibliography (partly classical scholarship and partly ornithological) to encourage further study, and provides students and ornithologists with the definitive study of ancient birds.

Book Description
Inselbergs are isolated rock outcrops that stand out abruptly from surrounding plains. Despite the widespread occurrence of granite inselbergs throughout all climatic and vegetational zones, their remarkably rich plant life was largely neglected in the recent literature. This richly and partly in color illustrated volume provides a detailed survey of all major abiotic and biotic features characteristic for inselbergs. The extreme environmental conditions on inselbergs are described in depth as well as specific adaptive traits of rock outcrop plants including their morphological, anatomical and physiological responses. The diversity and structure of inselberg plant communities are examined on a global scale with detailed regional accounts for different tropical and temperate zones.

Book Description
Poplars and willows form an important component of forestry and agricultural systems, providing a wide range of wood and non-wood products. This book synthesizes research on poplars and willows, providing a practical worldwide overview and guide to their basic characteristics, cultivation and use, issues, problems and trends. Prominence is given to environmental benefits and the importance of poplar and willow cultivation in meeting the needs of people and communities, sustainable livelihoods, land use and development.

Book Description
Local teachers and ministers extolling the virtues of hard work and loyalty to God and country. Veterans' groups and women's clubs promoting the military fighting radicalism, and equating business and patriotism. Industrial leaders gaining legal as well as moral influence over national domestic policy. Such scenes might seem to be lifted from a Sinclair Lewis novel or a Contract with America publicity video. But as John C. Hennen shows in this piercing analysis of early-twentieth-century American political culture, from 1916 to 1925 "Americanization" became the theme—indeed, the script—not only of West Virginia but of the entire nation. Hennen's interdisciplinary work examines a formative period in West Virginia's modern history that has been largely neglected beyond the traditional focus on the coal industry. Hennen looks at education, reform, and industrial relations in the state in the context of war mobilization, postwar instability, and national economic expansion. The First World War, he says, consolidated the dominant positions of professionals, business people, and political capitalists as arbiters of national values. These leaders emerged from the war determined to make free-market business principles synonymous with patriotic citizenship. Americanization, therefore, refers less to the assimilation of immigrants into the national mainstream than to the attempt to encode values that would guarantee a literate, loyal, and obedient producing class. To ensure that the state fulfilled its designated role as a resource zone for the perceived greater good of national strength, corporate leaders employed public relations tactics that the Wilson administration had refined to gain public support for the war. Alarmed by widespread labor activism and threatened by fears of communism, the American Constitutional Association in West Virginia, one of dozens of similar organizations nationwide, articulated principles that identified the well-being of business with the well-being of the country. With easy access to teacher training and classroom programs, antiunion forces had by 1923 rolled back the wartime gains of the United Mine Workers of America. Middle-class voluntary organizations like the American Legion and the West Virginia Federation of Women's Clubs helped implant mandated loyalty in schoolchildren. Far from being isolated during America's transformation into a world power, West Virginia was squarely in the mainstream. The state's people and natural resources were manipulated into serving crucial functions as producers and fuel for the postwar economy. Hennen's study, therefore, is a study less of the power or force of ideas than of the importance of access to the means to transmit ideas. The winner of the1995 Appalachian Studies Award is a significant contribution to regional studies as well as to our understanding of American culture during and after World War I.

Book Description
Although, as W.D. Billings notes in his chapter in this book. the development of physiological ecology can be traced back to the very beginnings of the study of ecology it is clear that the modern development of this field in North America is due in the large part to the efforts of Billings alone. The foundation that Billings laid in the late 1950s came from his own studies on deserts and subsequently arctic and alpine plants, and also from his enormous success in instilling enthusiasm for the field in the numerous students attracted to the plant ecology program at Duke University. Billings' own studies provided the model for subsequent work in this field. Physiological techniques. normally confined to the laboratory. were brought into the field to examine processes under natural environmental conditions. These field studies were accompanied by experiments under controlled conditions where the relative impact of various factors could be assessed and further where genetic as opposed to environmental influences could be separated. This blending of field and laboratory approaches promoted the design of experiments which were of direct relevance to understanding the distribution and abundance of plants in nature. Physiological mechanisms were studied and assessed in the context of the functioning of plants under natural conditions rather than as an end in itself.

Book Description
This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.
