The removal efficiency of viral particles by the coral reef sponge Negombata magnifica was measured. Virus particles were removed by the sponge at an average efficiency of 23.3% ± 2.9%. Significant amounts of nutrients are transported from virus particles to higher trophic levels via sponges. 

Virus–host interactions and their roles in coral reef health and disease

It is hypothesized that viruses of bacteria and eukaryotes dynamically interact with their hosts in the water column and with scleractinian (stony) corals to influence microbial community dynamics, coral bleaching and disease, and reef biogeochemical cycling.

Microbially mediated nutrient cycles in marine sponges.

A conceptual model is proposed that describes potential interactions and constraints in the major nutrient cycles in sponges, and it is suggested that shifting redox state induced by animal behavior like sponge pumping can exert great influence on the activities of symbiotic microbial communities.

The ecology and feeding biology of the sponge Rhopaloeides odorabile

Light availability does not physiologically regulate the size and depth distributions of R.odorabile across shelf locations, and variations in light, sediment and food are key factors structuring the distribution, abundance and physiology of many sessile marine invertebrates in benthic habitats, particularly those harbouring symbiotic (possibly phototrophic) microbial symbionts.

The question whether sponges are suitable for bioremediation of microbial pol- lution, since selective or preferential ingestion of certain bacteria by sponge may end up fueling growth of those grazed less, such as Vibrio spp.

Nutrient Fluxes Through Sponges

Marine sponges are able to process a variety of carbon (C), nitrogen (N), phosphorous (P), and silicon (Si) dissolved compounds, in addition to the particulate C, N, and P obtained through regular

Differential recycling of coral and algal dissolved organic matter via the sponge loop

The higher uptake and transformation rates of algal- compared with coral-derived DOM suggest that reef community phase shifts from coral to algal dominance may stimulate DOM cycling through the sponge loop with potential consequences for coral reef biogeochemical cycles and food webs.

Marine virus predation by non-host organisms

The finding that temperate sponges have the huge potential for constant and effective removal of viruses from the water column demonstrates that natural viral loss has, thus far, been underestimated.

Newly developed fluorescence and molecular techniques leave the field poised to make significant advances towards evaluating and quantifying viruses' effects on biogeochemical and ecological processes.

Viruses and Nutrient Cycles in the Sea Viruses play critical roles in the structure and function of aquatic food webs

As the authors' demands upon the ocean increase, so does the need to understand the ocean as an ecosystem, and basic to the un-derstanding of any ecosystem is knowledge of its food web, through which energy and materials flow.

The Ecological Role of Water-Column Microbes in the Sea*

Evidence is presented to suggest that numbers of free bacteria are controlled by nanoplankton~c heterotrophic flagellates which are ubiquitous in the marine water column, thus providing the means for returning some energy from the 'microbial loop' to the conventional planktonic food chain.

Novel applications of molecular genetic techniques have provided good evidence that viral infection can significantly influence the composition and diversity of aquatic microbial communities, supporting the hypothesis that viruses play a significant role in microbial food webs.
