“…Although the abilities and behaviors of larval fishes (reviewed by Leis 2006), such as detection of terrestrial noise and chemical cues (Simpson et al 2005, Dixson et al 2008, extensive swimming abilities (Stobutzki & Bellwood 1997), and vertical distribution (Cowen & Castro 1994), can have large influ-ences on recruitment, oceanographic patterns on both the geographic and temporal scales can also contribute to recruitment processes (Cowen et al 2000, Bradbury & Snelgrove 2001, Schirripa & Colbert 2006, Galarza et al 2009). Longer PLDs can lead to extensive dispersal (Shanks 2009), and this could cause extensive gene flow and diminished levels of population genetic structure.…”

We investigated intraspecific variability in phenotype and population genetic structure of yellowhead jawfish Opistognathus aurifrons from 4 different locations in the Caribbean region: South Florida (USA), Bimini (Bahamas), St. Thomas (US Virgin Islands), and Aruba. Discriminant function analysis (DFA) of 9 melanistic traits in the head region resulted in clear separation between Bimini and the other 3 populations. South Florida, St. Thomas, and Aruba slightly overlapped in patterning, with St. Thomas forming the transition between South Florida and Aruba. DFA of 17 morphometric characters elucidated differentiation among the 4 populations with some overlap between populations. Analysis of concatenated cytochrome c oxidase subunit I (COI) and mitochondrial control region (mtCR) sequences revealed substantial differences among O. aurifrons populations (pairwise Φ ST = 0.185−0.566), although there was a lack of reciprocal monophyly. Differences in patterning and morphometrics constituted different phenotypes that predominated in each location, with high levels of genetic differentiation between sampled populations. Bimini was most divergent in phenotype, while Aruba was most divergent in genetics. As such, variations in phenotype and genetics are not congruent for O. aurifrons investigated in this study.

“…From these studies we have learned that many larvae are strong swimmers (Leis 2006), that they are able to determine the direction of reefs (Leis et al 1996), and are attracted to and can orient towards sound , Simpson et al 2005a, Montgomery et al 2006). Second, other empirical studies on the early stages of some species that can be reared in captivity have provided information on the ontogenic development of hearing (Simpson et al 2005b, Montgomery et al 2006) and swimming abilities (Leis 2006). Third, techniques have been applied that glean information about the larval period indirectly.…”

Elevated mortality of fish larvae on coral reefs drives the evolution of larval movement patterns

Coral reef fishes typically undergo a pelagic larval phase prior to recruitment to reef habitat. This is potentially risky, but likely to be important in connecting populations and avoiding local crowding. Predation pressures on larvae on and off the reef are likely to differ both in origin and intensity. In this study, we used individual-based models to explore in isolation the effect of elevated levels of larval mortality on the reef in 22 different landscapes. We allowed the movement of highly simplified larvae to evolve through selection and mutation events and tracked emerging strategies over 180 generations. The pressure of increased larval mortality on the reef affected overall population sizes and selected for higher levels of larval movement. However, the evolution of movement was constrained, and self-recruitment back to the reef of origin was prevalent, with levels rarely dropping below 50%. The evolved strategies were highly landscape specific, suggesting that movement in contiguous reefs is more readily evolved than at isolated reefs. Future development of this simulation approach will provide a valuable research tool for exploring important evolutionary, ecological, and management-based questions.KEY WORDS: Evolved strategy · Larvae · Coral reef fishes · Active dispersal · Self-recruitment Resale or republication not permitted without written consent of the publisher

“…However, we do know that embryos respond to sound while developing in their benthic eggs (Simpson et al 2005b), suggesting that the potential for imprinting and relating sound cues with their home reef sound signature exists. If so, we may soon be able to provide definitive evidence to link these new discoveries to self-recruitment processes.…”

Dispersal without errors: symmetrical ears tune into the right frequency for survival

et al. 2007

Vertebrate animals localize sounds by comparing differences in the acoustic signal between the two ears and, accordingly, ear structures such as the otoliths of fishes are expected to develop symmetrically. Sound recently emerged as a leading candidate cue for reef fish larvae navigating from open waters back to the reef. Clearly, the integrity of the auditory organ has a direct bearing on what and how fish larvae hear. Yet, the link between otolith symmetry and effective navigation has never been investigated in fishes. We tested whether otolith asymmetry influenced the ability of returning larvae to detect and successfully recruit to favourable reef habitats. Our results suggest that larvae with asymmetrical otoliths not only encountered greater difficulties in detecting suitable settlement habitats, but may also suffer significantly higher rates of mortality. Further, we found that otolith asymmetries arising early in the embryonic stage were not corrected by any compensational growth mechanism during the larval stage. Because these errors persist and phenotypic selection penalizes asymmetrical individuals, asymmetry is likely to play an important role in shaping wild fish populations.
