Larval Biology & Behavior

In addition to my ocean acidification-related work with larvae, I have collaborated with researchers from other universities to explore how larvae experience their environment prior to settlement. Using a larval flow tank, we examined fine-scale settlement behavior of cyphonautes larvae of the bryozoan, Membranipora membranacea, in response to two different algal substrata. We showed that these larvae altered their search strategies depending on habitat preference (Matson et al., 2010). Larvae exhibited fine-scale active search behaviors with the preferred alga but broad-scale passive behaviors in the presence of less-preferred alga. Understanding such behaviors helps to shed light on larval settlement processes and the mechanisms linking larval supply and recruitment.
