This book is an extended argument for abandoning the species rank. Instead, the author proposes that the rank of "species" be replaced by a pluralistic and multi-level view. In such a view, all clades including the smallest identifiable one would be named and studied within a phylogenetic context. What are currently called "species" represent different sorts of things depending on the sort of organisms and processes being considered. This is already the case, but is not formally recognized by those scientists using the species rank in their work. Adopting a rankless taxonomy at all levels would enhance academic studies of evolution and ecology and yield practical benefits in areas of public concern such as conservation. KEY FEATURES Proposes the replacement of restrictive species concepts with a pluralistic view Suggests abandoning the formal taxonomic rank of "species" Considers zoological, botanical, and microbiological aspects of the species level Deals with practical issues such as conservation, inventories, and field guides.

This book outlines the principles of flight, of birds in particular. It describes a way of simplifying the mechanics of flight into a practical computer program, which will predict in some detail what any bird, real or hypothetical, can and cannot do. The Flight program, presented on the companion website, generates performance curves for flapping and gliding flight, and simulations of long-distance migration and accounts successfully for the consumption of muscles and other tissues during migratory flights. The program is effectively a working model of a flying bird (or bat or pterosaur) and

The geographic and stratigraphic distribution of fossil nonmarine Ostracoda in the United States are summarized in this book, followed by diagnoses of the subject species, references to literature and 34 plates of illustrations. This work shows the great diversity and usefulness of this interesting class of organisms which are small bivalved aquatic crustaceans that occupy both marine and nonmarine environments. Many are characteristic of estuarine and other tidal habitats, but only a few occupy hypersaline waters. One or two kinds are found in wet soils, or in leaf or flower cups in
