“…Seawater conditioned in Barnstable Harbor sediment induces metamorphosis of mud snail larvae (Scheltema, 1961), and sediment-associated phytoplankton may also influence larval behavior. Some larvae, including Crepidula spp., will swim downward and settle in the presence of adult-conditioned seawater or synthetic analogs (Eyster and Pechenik, 1988;Turner et al, 1994;Browne and Zimmer, 2001). Adult Crepidula spp.…”

Marine larval dispersal is affected by hydrodynamic transport and larval behavior, but little is known about how behavior affects large-scale patterns of dispersal and recruitment. Intertidal habitats are characterized by strong and variable turbulence relative to shelf and pelagic waters, so larval responses to turbulence may affect both dispersal and habitat selection. This study combined observations and theoretical approaches to model gastropod larval responses to multiple physical variables in a well-mixed tidal inlet. Physical measurements and larvae were collected in July 2004 in Barnstable Harbor, Massachusetts (USA). Physical measurements were incorporated in an advection-diffusion model where larval vertical velocity is a function of turbulence dissipation rate, temperature, and the temperature gradient. Modeled larval distributions were fitted to observed concentration profiles by maximum likelihood to estimate larval behavioral velocity (swimming or sinking) as a function of environmental conditions. These quantitative behavior estimates were used to test hypotheses about behavioral differences among groups and to assess the relative impact of different cues on overall larval behavior. Larvae of five common gastropod species from different coastal habitats reacted most strongly to turbulence but had genus-specific responses to environmental cues. Larvae of a species from tidal inlets (the mud snail Nassarius obsoletus) had near-zero velocities under calmer conditions and sank in strong turbulence. In contrast, larvae from exposed beach habitats (Crepidula spp. and Anachis spp.) sank in weak turbulence and swam up in strong turbulence, with additional responses to temperature and temperature gradient. Larval responses also differed between small and large size classes and between flood and ebb tides. Behavior of mud snail larvae would contribute to retention inside the inlet and near adult habitats, whereas behavior of beach snail larvae would contribute to rapid export from muddy inlets lacking suitable adult habitats.

“…It was argued that dissolved settlement cues would be ineffective due to rapid dilution in seawater and, even if detected by larvae, the weak swimming abilities of most would prevent them from swimming towards the source of the cue, particularly in turbulent environments (Crisp 1974, Butman 1987. However, it is now clear that a number of species of marine invertebrate settle in response to dissolved chemical cues (Hadfield & Paul 2001), in still water assays (Williamson et al 2000, Swanson et al 2004), laboratory flumes under realistic flow conditions (Turner et al 1994, Tamburri et al 1996, and in the field (Browne & Zimmer 2001). This paper reports the first in situ quantitative measurements of a characterised chemical cue in seawater.…”

Mangrove-sponge associations: a possible role for tannins

et al. 2009

A positive correlation between sponge coverage and tannin concentrations in prop roots of Rhizophora mangle L. has previously been reported. However, the ecological role of tannins within the mangrove sponge association remains speculative. This study investigated whether tannins play a role in sponge recruitment and assessed tannin and polyphenol production in R. mangle roots in response to sponge colonization. We demonstrated in a field experiment using artificial substrates with different tannin concentrations that tannins are positively involved in larval recruitment of the sponge Tedania ignis and that roots significantly enhanced tannin and polyphenolic content in response to natural and experimental sponge fouling. Differential recruitment in response to tannins may have been the result of a behavioral response in sponge larvae. It is also possible that tannins affected the structure of the fouling microbial biofilm on the artificial substrate, or tannins affected the post-settlement dynamics of sponge recruits. Elevations in concentrations of tannins and polyphenolic compounds upon coverage with sponges, combined with differential recruitment of T. ignis in response to differences in tannin concentrations, may indicate a positive feedback in recruitment. This may in part explain the typical heterogeneity in sponge coverage and community composition among roots.
