In one project, we explore the causal mechanisms that underlie mortality in marine fish larvae, focusing on the critical period of first feeding. We investigate how the functional design of the feeding mechanism influences prey-capture performance of marine fish larvae. We address several questions, including how the feeding mechanism develops during the early-life history stages of marine fishes; how the feeding mechanism of marine fish larvae work; and how prey type influences preyÂ–capture performance in marine fish larvae. Through this research, students and I will attempt to develop stage- and speciesÂ–specific models to demonstrate the interplay between feeding functional morphology, preyÂ–selectivity, and feeding performance in marine fish larvae.
Other projects involve investigating the intra- and inter-specific variation in feeding biomechanics and behavior in coral reef and estuarine fishes. Estuaries and lagoons serve as nursery grounds for a number of fish species, including those of commercially and recreationally importance. Coral reefs harbor one of the most diverse fish assemblages in the world. Anthropogenic, coupled with natural disturbances alter fish habitats that may cause variations in the physiology and behavior of fishes. Students and I explore how changes in food supply, habitat characteristics, temperature, salinity and other environmental parameters influence the ecological physiology of fishes. Our lack of understanding of how fishes solve these problems underscores the need to explore the compensatory mechanisms (e.g., morphological and physiological) that enable fishes to counteract these environmental perturbations.
