Building on previous syntheses of knowledge about loggerhead sea turtle biology and population status, Bolten (Archie Carr Center for Sea Turtle Research, U. of Florida) and Witherington (Marine Research Institute, Florida Fish and Wildlife Conservation Commission) identify information gaps regarding this threatened generalist species. Contributors to 18 chapters present current knowledge about its life cycle in marine habitats globally, demographic and ecosystem models, and conservation perspectives. There are ample maps and data tables but hardly a turtle photo. Annotation ©2004 Book News, Inc., Portland, OR (booknews.com)
