Ebook: Marine Pelagic Cyanobacteria: Trichodesmium and other Diazotrophs

Planktonic marine cyanobacteria are abundant and significant in the biogeochemistry of the sea. This volume focuses on the filamentous cyanobacteria, particularly those in the genus Trichodesmium which are common in tropical and subtropical seas. A portion of this book also concerns bloom-forming cyanobacteria in the Baltic Sea area. Filamentous cyanobacteria are important as primary producers and for the fixation of atmospheric nitrogen and thus are significant in global cycling of both of these elements. In recent years, through the application of new techniques and intensive multi-disciplinary research programs, progress has been made in understanding both the biology of these cyanobacteria and their place in the marine food web.
A broad range of topics is covered in this book, ranging from molecular biology, physiology, ultrastructure, enzyme localization, toxicology, remote sensing, buoyancy, herbivory and the ecology of these organisms in the marine food web. This volume is an outgrowth of a NATO-sponsored meeting held in May 1991 in Bamberg, Germany, and represents the latest synthesis on these marine phytoplankters.
