A morphological and functional basis for maximum prey size in piscivorous fishes
Fish predation is important in shaping populations and community structure in aquatic systems. These predator-prey interactions can be influenced by environmental, behavioural and morphological factors. Morphological constraints influence the feeding performance of species, and interspecific differences can thus affect patterns of resource use. For piscivorous fishes that swallow prey whole, fe...
متن کاملEffect of prey abundance and size on the distribution of demersal fishes
Many demersal fish species rely on benthic prey as food sources for part of, or in some cases, all of their life history. We investigated the relationships between prey and predator abundance and prey size and predator mouth gape size for nine demersal fish species. Of the species analysed, four showed a significant positive increase in abundance with increasing prey abundance. Prey size is tho...
متن کاملBlue and Yellow Signal Cleaning Behavior in Coral Reef Fishes
Marine cleaning symbioses are classic examples of mutualism: cleaners remove and consume ectoparasites from "client" fish, while clients benefit from a reduction in ectoparasites. However, how clients recognize cleaners and decide not to eat them is unclear. Color and body pattern are thought to be important in signaling cleaning services to coral reef fish; in this study, we tested the long-he...
متن کاملRECRUITMENT DYNAMICS OF REEF FISHES: PLANKTONIC PROCESSES, SETTLEMENT AND DEMERSAL ECOLOGIES, AND FISHERY ANALYSIS William J. Richards and Kenyon
Factors influencing variability of recruitment in coral reef fishes are of great theoretical and applied interest for population dynamics, oceanography, and fishery management. Due to the complexities of evaluating the many factors influencing recruitment processes throughout the life history of mcroplanktonic organisms, recruitment is often an umbrella-term encompassing interrelated problems i...
متن کاملHabitat-associated intraspecific variation in behavior and stress responses in a demersal coral reef fish
Habitat heterogeneity has been linked to species diversity and abundance, but can also generate intraspecific behavioral variation that has functional consequences for how animals respond to environmental stressors. Previously, we found that bicolor damselfish Stegastes partitus inhabiting the fringing coral reefs of Curaçao exhibited intraspecific variation in agonistic behaviors in spatial pa...
