This landmark scientific reference for scientists, researchers, and students of marine biology tackles the monumental task of taking a complete biodiversity inventory of the Gulf of Mexico with full biotic and biogeographic information. Presenting a comprehensive summary of knowledge of Gulf biota through 2004, the book includes seventy-seven chapters, which list more than fifteen thousand species in thirty-eight phyla or divisions and were written by 138 authors from seventy-one institutions in fourteen countries.This first volume of Gulf of Mexico Origin, Waters, and Biota, a multivolumed set edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle, provides information on each species' habitat, biology, and geographic range, along with full references and a narrative introduction to the group, which opens each chapter.

When Franklin published her book on cyst nematodes in 1951, the cyst nematodes were already known as serious pests of brassicas, cereals, potatoes and sugar beets. However, at that time this group of nematode, with about 12 species, was considered tobe largely temperate in distribu tion. Now a total of 105 species (including those that are considered as synonyms or species inquirende by some or all) within six genera of cyst nematodes have been described from temperate, tropical, and subtropical regions and at least five species are important constraints to crop produc tion in tropical agriculture. The previous impression of localization of cyst nematodes in the temperate region was seemingly an artifact due to a greater concentration of nematologists in the temperate regions. Based on my own experience of working in several Asian and African countries, I believe that many more undescribed species are present in the tropical countries of Asia and Africa, and probably in other tropical regions. Most growers, extension workers, and research managers in these regions are still not aware of the possible harm of presence of these nematodes in their agricultural soils. The cyst nematodes are perhaps smaller than the smallest available computer chip but they are very well programmed to survive and pro pagate despite severe hardships. These nematodes are very selective in their choice of food; about 50% of known species are parasites of plants mainly in the families Poaceae and Fabaceae.
