The honey bees were formerly seen as a small, static group comprising four species, whose behavior and ecology were simple variants on the patterns found in Apis mellifera. The picture now is one of a large, actively speciating group, reflecting in part the complex geological and biological influence of the Apis environment. Research on this diversity has benefitted from new techniques of DNA analysis applied to several long-standing problems in honey bee phylogenetics and that are reported in this volume. The behavior and ecology of the Apis species and populations are also more diverse and differentiated than previously recognized: Radically different orientation systems as expressed through dance language exist in various species. This study of Apis will be of great interest not only to biologists and apiculturalists but to anyone interested in systematics, genetics, and ethology. Our view of apis has changed radically in the past few years as a result of recent research on the Asian honeybee. The contributors to this book focus on systematics, genetics, behaviour and ecology to offer a synthesis for understanding this economically and scientifically important genus.

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.

Honeybees are as small as flies or as large as hornets, nesting in nar row cavities of trees and rocks or in the open on large limbs of trees 30 m above ground. They occur in tropical zones and in the forests of the Ural mountains, they survive seven months of winter and even longer periods of drought and heat. Historically, they lived through a extended time of stagnation in the tropics from the mid-Tertiary, but then experienced an explosive evolution during the Pleistocene, re sulting in the conquest of huge new territories and the origin of two dozen subspecies in Apis mellifera. This vast geographic and ecologic diversification of the genus Apis was accompanied by a rich morphological variation, less on the level of species than at the lowest rank, the subspecies level. Variation being exclusively of a quantitative kind at this first step of speciation, tradi tional descriptive methods of systematics proved to be unsatisfactory, and honeybee taxonomy finally ended up in a confusing multitude of inadequately described units. Effective methods of morphometric-sta tistical analysis of honeybee popUlations, centered on limited areas, have been developed during the last decades. Only the numerical characterization of the populations, together with the description of behavior, shows the true geographic variability and will end current generalizations and convenient stereotypes.

This book summarizes the current progress of bee researchers investigating the status of honey bees and possible reasons for their decline, providing a basis for establishing management methods that maintain colony health. Integrating discussion of Colony Collapse Disorder, the chapters provide information on the new microsporidian Nosema ceranae pathogens, the current status of the parasitic bee mites, updates on bee viruses, and the effects these problems are having on our important bee pollinators. The text also presents methods for diagnosing diseases and includes color illustrations and tables.

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.
