Nematodes are one of the most abundant groups of invertebrates on the face of the earth. Their numbers are estimated to range from 1000 per cm2 in the sand-covered hydrogen sulphide black zone beneath the ocean floors to 1.2 billion in a single hectare of soil. Estimates for their species diversity range from 100 000 to 10 million. The past history of nematodes is a mystery, since very few fossils have been discovered. This book establishes a solid base in palaeonematology with descriptions of 66 new fossil species and accounts of all previous fossil and subfossil nematodes from sedimentary deposits, coprolites, amber and mummies. It shows how nematode fossils can be used to establish lineages at various locations and time periods in the earth s history and when nematodes entered into symbiotic and parasitic associations with plants and animals.

In this complete and thorough update of Arthur Boucot's seminal work, Evolutionary Paleobiology of Behavior and Coevolution, Boucot is joined by George Poinar, who provides additional expertise and knowledge on protozoans and bacteria as applied to disease. Together, they make the Fossil Behavior Compendium wider in scope, covering all relevant animal and plant groups and all epochs, and providing a detailed review of animal and plant fossil behavior in terrestrial and aquatic environments. Fossil behavior encompasses not only past evidence of the life history of an organism but also behavioral, predation, and symbiotic interactions, including parasitism. This book compares patterns of behavior and coevolution in the past with those of the present-day descendants. It also discusses how to evaluate the rates of evolution of behavior and coevolution at various taxonomic levels. The compendium emphasizes the interactions between fossils and compares these interactions with present-day counterparts. It also provides new discussions on topics related to fossils in amber. Keeping Boucot's trademark, easy-to-read style, the book includes new findings never published previously, reports not easily accessed, numerous examples, 40 tables, 285 illustrations-some published here for the first time-and a four-page color insert. The book provides a concise account of the evidence for varied disease types recognized to date in the fossil record.
