Observed and simulated swimming trajectories of late-stage coral reef fish larvae off the Florida Keys
The supply of coral reef fish larvae from the open ocean to nearshore reefs is vital for the persistence of local fish populations. Larvae that are competent to settle are often fast swimmers, and their transport to suitable settlement habitat may depend on swimming behavior as well as currents. Our goal was to measure the effects of swimming behavior during the final period of larval transport...
متن کاملWave energy and swimming performance shape coral reef fish assemblages.
Physical factors often have an overriding influence on the distribution patterns of organisms, and can ultimately shape the long-term structure of communities. Although distribution patterns in sessile marine organisms have frequently been attributed to functional characteristics interacting with wave-induced water motion, similar evidence for mobile organisms is lacking. Links between fin morp...
متن کاملEctoparasites increase swimming costs in a coral reef fish.
Ectoparasites can reduce individual fitness by negatively affecting behavioural, morphological and physiological traits. In fishes, there are potential costs if ectoparasites decrease streamlining, thereby directly compromising swimming performance. Few studies have examined the effects of ectoparasites on fish swimming performance and none distinguish between energetic costs imposed by changes...
متن کاملCoral Reef Fish Larvae Settle Close to Home
Population connectivity through larval dispersal is an essential parameter in models of marine population dynamics and the optimal size and spacing of marine reserves. However, there are remarkably few direct estimates of larval dispersal for marine organisms, and the actual birth sites of successful recruits have never been located. Here, we solve the mystery of the natal origin of clownfish (...
متن کاملChemical spying in coral reef fish larvae at recruitment.
When fish larvae recruit back to a reef, chemical cues are often used to find suitable habitat or to find juvenile or adult conspecifics. We tested if the chemical information used by larvae was intentionally produced by juvenile and adult conspecifics already on the reef (communication process) or whether the cues used result from normal biochemical processes with no active involvement by cons...
