Increasing sea surface temperatures are predicted to affect many biological processes including sponge heterotrophy. Sponges are a vital component in benthic-pelagic coupling, and therefore these organisms have a significant impact on bacterioplankton communities.

In this study, DNA was extracted from each of three individual sponges from four sponge species collected in a shallow mangrove cut in Florida Bay near Key Largo, Florida. A fragment of the 16S rRNA gene from sponge-associated bacteria was amplified using the polymerase chain reaction (PCR).

On a 600-m² section of Conch Reef, species-specific biomass for all nonencrusting sponges was measured. The biomass data combined with species-specific dissolved inorganic nitrogen (DIN) flux rates yielded the benthic DIN flux from 14 species, and allowed us to extrapolate these data to the total ...

Any variability in the environment should therefore be reflected in the tissue of the sponge. However, some sponges are known to host large microbial communities, and the influence of these microbes on the nutrition of their host is largely unknown. To examine the influences on variability in sponge nutrition, we collected tissue samples from eleven sponge species at thirteen ocean and bayside sites near Key Largo, Florida. We also collected sediment ...
