The fundamental purpose of this book is to synthesize the divergent literature on aquatic lipids into a coordinated, digestible form. It addresses lipid composition and production in freshwater organisms, with chapters on phytoplankton, zooplankton and benthic invertebrates. A common theme is the function of lipids in aquatic food webs. Methodologies to determine the lipid content of aquatic samples and suggestions as to the utility of fatty acids as trophic markers are provided. Students and researchers in ecology, phycology, aquatic toxicology, physiological ecology and limnology will find this an invaluable guide and reference.
