Habitat-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...
متن کاملColour thresholds in a coral reef fish
Coral reef fishes are among the most colourful animals in the world. Given the diversity of lifestyles and habitats on the reef, it is probable that in many instances coloration is a compromise between crypsis and communication. However, human observation of this coloration is biased by our primate visual system. Most animals have visual systems that are 'tuned' differently to humans; optimized...
متن کاملRegional Endothermy in a Coral Reef Fish?
Although a few pelagic species exhibit regional endothermy, most fish are regarded as ectotherms. However, we document significant regional endothermy in a benthic reef fish. Individual steephead parrotfish, Chlorurus microrhinos (Labridae, formerly Scaridae) were tagged and their internal temperatures were monitored for a 24 h period using active acoustic telemetry. At night, on the reef, C. m...
متن کاملOcular media transmission of coral reef fish — can coral reef fish see ultraviolet light?
Many coral reef fish are beautifully coloured and the reflectance spectra of their colour patterns may include UVa wavelengths (315-400 nm) that are largely invisible to the human eye (Losey, G. S., Cronin, T. W., Goldsmith, T. H., David, H., Marshall, N. J., & McFarland, W.N. (1999). The uv visual world of fishes: a review. Journal of Fish Biology, 54, 921-943; Marshall, N. J. & Oberwinkler, J...
متن کاملColour vision in coral reef fish.
Over many millions of years, sea creatures have developed a range of light reflectance properties. One example is the large variation in the patterns and colours of fish inhabiting the world's coral reefs. Attempts to understand the significance of the colouration have been made, but all too often from the perspective of a human observer. A more ecological approach requires us to consider the v...
