The use of discriminate function analysis in the identification of two species of larval smelt, Spirinchus thaleichthys and Hypomesus T. transpacificus, in the Sacramento-San Joaquin estuary, California
The objectives of this study are to identify the larval forms of the two species of smelt, Spirinchus thaleichthys and Hypomesus transpacificus transpacificus, and to better describe their spawning times in the Sacramento-San Joaquin Estuary.

Larval fish assemblages of selected estuarine and coastal systems in Kwazulu-Natal, South Africa
This study focuses describing assemblages of fish larvae occurring in potential nursery habitats and elucidating the recruitment processes of fishes in the KwaZulu-Natal region. The composition, the degree of estuarine-association of all taxa, temporal and spatial abundance patterns, developmental …

Modeling the processes affecting larval haddock (Melanogrammus aeglefinus) survival on Georges Bank
… in determining food availability to the haddock larvae. Experiments conducted with a one-dimensional vertical behavior model suggested that larval haddock should focus on avoiding visual predation when they are small and vulnerable and food is readily available. Coupled hydrodynamics, …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
The ecological integrity of tropical habitats, including mangroves, seagrass beds and coral reefs, is coming under increasing pressure from human activities. Many coral reef fish species are thought to use mangroves and seagrass beds as juvenile nurseries before migrating to coral reefs as adults. …

Larval dispersal between hydrothermal vent habitats
… for which reliable identification of vent larvae is necessary, is critical to understanding larval dispersal. In gastropod species, the retention of the larval shell on the adult allows identification without the necessity of culturing larvae or using species-specific molecular probes, both …
