attribute NC_GLOBAL summary String Photosymbionts expand the metabolic capabilities of host sponges, but their potential role in mediating niche partitioning on crowded and oligotrophic coral reefs is unknown. To address this question, we conducted two ex situ isotope tracer experiments with ten of the most ecologically dominant sponge species in the Caribbean. This research was carried out in Bocas del Toro, Panama. To target autotrophic and heterotrophic nutrient acquisition by microbial symbionts, we incubated sponges in seawater laced with the inorganic compounds NaH13CO3 and Na15NO3 under both light and dark conditions. We also measured host sponge heterotrophic feeding rates by incubating the same species with 13C- and 15N-labeled bacterial cells. Sponge cells isolated from sponge species hosting photosymbionts were significantly more enriched in 13C and 15N from inorganic sources, and 72 % of the variation in 13C and 15N enrichment across samples was explained by sponge species identity. Dark enrichment of 13C was minimal, but all species were enriched in 15N in the dark due to heterotrophic microbial nitrogen assimilation. Sponges rapidly consumed bacterial cells, but there was substantial variation in heterotrophic feeding rates among sponge species. When considering all three resource pools (symbiont autotrophy, symbiont heterotrophy, and sponge heterotrophy) and both elements, sponge species identity accounted for over 80 % of variation among specimens; in addition, we observed a clear separation of sponge species along a continuum of heterotrophic feeding on particulate organic matter to autotrophic metabolism via photosymbionts. These data demonstrate that the combined influence of sponge and photosymbiont metabolism enable coexisting sponge species to exploit unique resource pools on Caribbean reefs.
