Book Description
ÿThe genus Chlerogella historically has been one of the most infrequently encountered lineages of augochlorine bees (Apoidea: Anthophila: Halictidae: Augochlorini). By 1993 only three species were described and less than 40 specimens were known of a group presumed to be species poor and of limited geographic scope. With their frequently elongate heads and characteristic habitus, species of the genus are quite distinctive, and although the available material of these rare bees has grown to only 165, the number of species and their broader distribution has expanded significantly. This volume completes a revision of the world?s species of Chlerogella, completing the large South American fauna (Part I, covering Central America, is available in ZooKeys 23). In total, the genus has grown from three species to 34 (27 are treated in the current work). Color photomicrographs, detailed descriptions, and keys are provided to permit identification of the currently known taxa and aid the future discovery of new species. Unfortunately, almost nothing is known of the biology of these fascinating bees and this work will hopefully aid the discovery and elucidation of their natural history.

Book Description
What are the evolutionary mechanisms and ecological implications behind a pollinator choosing its favourite flower? Sixty-five million years of evolution has created the complex and integrated system which we see today and understanding the interactions involved is key to environmental sustainability. Examining pollination relationships from an evolutionary perspective, this book covers both botanical and zoological aspects. It addresses the puzzling question of co-speciation and co-evolution and the complexity of the relationships between plant and pollinator, the development of which is examined through the fossil record. Additional chapters are dedicated to the evolution of floral displays and signalling, as well as their role in pollination syndromes and the building of pollination networks. Wide-ranging in its coverage, it outlines current knowledge and complex emerging topics, demonstrating how advances in research methods are applied to pollination biology.
Evolution and Phylogeny of Bees

Book Description
Volume 161 of Zoologica reviews and analyses the evolution and phylogeny of bees. It is subdivided into two parts Part One: A Preamble to the Evolution and Phylogeny of Bees provides a complete and critical review of all previous attempts to reconstruct the phylogenetic tree of bees (Anthophila / Apiformes) based on morphological, bionomic and molecular approaches and pre- sented in chronological sequence up to and including recent publications. At the same time, the introductory part examines trends in the classification of bees and compares available hypotheses of bee evolution. Part One closes with a family-wise delineation of the fossil history of bees. Part Two: A Phylogenetic Study of Bees in Light of Morphological Evidence adds an experimental study to complement the bibliographical analysis provided in Part One. The phylogenetic relationships of the larger taxonomic units of bees are tested anew using an extensive dataset of selected morphological features. The study uses all common and current computer-aided techniques of cladistic analysis (parsimony, successive/implied weight, Bayesian and neighbor-joining), which are applied to representatives of all seven families, 22 subfamilies and 48 of 58 tribes of bees. The conclusions drawn from this are evaluated for the major groups (i.e., short-tongued and long-tongued bees), and separately for the families, subfamilies and tribes in each case. In a world currently dominated by molecular genetic approaches to phylogeny, this study clearly demonstrates that it is not anachronistic to engage in morphological efforts, because progress can be significantly advanced and the pool of available scientific arguments enriched. The diversity of the object of investigation justifies a variety of methods. This monograph is a much needed reference work of high practical value for all students of bee evolution, phylogeny and morphology. Further, it is ideally suited as good introductory reading material for university level students.

Book Description
Insects are the most diverse group of organisms in the 3 billion-year history of life on Earth, and the most ecologically dominant animals on land. This book chronicles for the first time the complete evolutionary history of insects: their living diversity, relationships and 400 million years of fossils. Whereas other volumes have focused on either living species or fossils, this is the first comprehensive synthesis of all aspects of insect evolution. The book is illustrated with 955 photo- and electronmicrographs, drawings, diagrams, and field photos, many in full colour and virtually all of them original. The book will appeal to anyone engaged with insect diversity: professional entomologists and students, insect and fossil collectors, and naturalists.
