An integrative investigation of sensory organ development and orientation behavior throughout the larval phase of a coral reef fish
Abstract The dispersal of marine larvae determines the level of connectivity among populations, influences population dynamics, and affects evolutionary processes. Patterns of dispersal are influenced by both ocean currents and larval behavior, yet the role of behavior remains poorly understood. Her...

Abstract The dispersal of marine larvae determines the level of connectivity among populations, influences population dynamics, and affects evolutionary processes.
