Transport of non-decapod invertebrate larvae in estuaries: an overview
Abstract:Limited information reveals a variety of potential larval adaptations to estuarine transport problems and suggests that the tidally-entrained behaviors characteristic of many decapod larvae may be less developed in other invertebrate larvae. Several difficulties inhibit study of non-decapod larval transport in estuaries, including poor taxonomic knowledge of larvae, their perceived lack of commercial value, sampling and processing difficulties, inadequate knowledge of the physical and biological environments and extreme variation in physical characteristics between estuaries. The mechanisms and significance of larval transport cannot be separated from the overall biology of the organisms; consequently, studies may best be carried out in estuaries where long-term, quantitative information on distribution and abundance of adult populations, recruitment, physical factors, and predators already exists. In such localities, simultaneous intensive investigations of pertinent environmental factors and larvae within specific taxonomic groups, together with laboratory and field studies of individual larval behavior, can reveal ecologically important differences between species and increase understanding of the complexities of estuarine ecology in general.
