Nudibranch predation boosts sponge silicon cycling

Abstract: Diatoms play a key role in the marine silica cycle, but recent studies have shown that sponges can also have an important effect on this dynamic. They accumulate large stocks of biogenic silica within their bodies over long periods, which are thought to vary little on an intra-annual scale. The observation of an abrupt decline in sponge biomass in parallel with large increases in abundance of a spongivorous nudibranch (Doris verrucosa) led us to conduct a year-long study on the effect of nudibranch predation o… Show more

“…Dorid nudibranchs (Order: Nudibranchia, Family: Dorididae) are slow-moving, shell-less, marine gastropod mollusks that feed on sessile prey, among which some species exclusively feed on sponges (Cimino et al 1999 ; López-Acosta et al 2023 ). Some sponge species are chemically defended and represent an important source of biologically active secondary metabolites, containing unique structures and displaying great diversity (Hong et al 2022 ).…”

“…Records of sponge consumers in temperate systems are scarcer and more fragmentary than in tropical environments. In temperate environments consumers of sponges are mostly invertebrates like opisthobranchs, sea stars, urchins, chitons, limpets, crabs and endobiont polychaetes (Guida 1976;Wulff 2006;López-Acosta et al 2023). Some authors agree that sponge populations from tropical coral reefs are mainly bottom-up controlled (Lesser 2006;Lesser and Slattery 2013;Trussell et al 2006), whereas others point out that they are only driven by a top-down control (Pawlik et al 2013(Pawlik et al , 2015.…”
