“…Elevated temperatures may also result in changes in sponge-associated bacterial communities (Lemoine et al 2007). The rate of ARBS progression during this period was also much more rapid than previously reported (Olson et al 2006), likely an effect of the elevated seawater temperature. Total protein content has also been reported to change seasonally in sponges (Elvin 1979), possibly due to reproductive stage.…”

“…Diseases of sponges were documented as early as the 1940s, when disease ravaged the commercial sponge industry in the Caribbean (Galtsoff et al 1939, Smith 1941. Sponge diseases have recently been rediscovered across the globe (Rützler 1988, Gaino et al 1992, Vacelet et al 1994, Webster et al 2002, Cervino et al 2006, Cowart et al 2006, Olson et al 2006, Wulff 2006, Webster 2007, Maldonado et al 2010.Nutrient enrichment is hypothesized to contribute to the onset and severity of coral diseases by elevating microbial growth rates, enhancing virulence of pathogens, and promoting blooms of algae or cyanobacteria (Glibert et al 2004, Rodier & Le Borgne 2008. Correlative studies suggest that increased concentrations of nutrients are associated with increased prevalence of various coral diseases, including Black Band Disease (Kuta & Richardson 2002, Kaczmarsky et al 2005, White Plague type II (Kaczmarsky et al 2005), Porites Ulcerative White Spots, and Porites growth anomalies (Kaczmarsky & Richardson 2011).…”

“…Increased microbial virulence and/or compromised host resistance linked to global warming has already been postulated as a cause of many mass mortalities of marine organisms (139,140), and it will be of great interest (and concern) to see how marine sponges are affected by predicted rises in seawater temperature in the future. Other reports of diseases in sponges include the so-called Aplysina red band syndrome, afflicting aplysinid sponges on Bahaman reefs (262), cyanobacterial overgrowth of Geodia papyracea (330), and repeated observations of diseased sponges on a Panamanian coral reef over a 14-year period (492). Bleaching of Xestospongia muta and other Caribbean sponges has also been reported (64,91,251,441), but it remains to be established whether, as is the case for some corals (325,326) (54).…”

SUMMARY Marine sponges often contain diverse and abundant microbial communities, including bacteria, archaea, microalgae, and fungi. In some cases, these microbial associates comprise as much as 40% of the sponge volume and can contribute significantly to host metabolism (e.g., via photosynthesis or nitrogen fixation). We review in detail the diversity of microbes associated with sponges, including extensive 16S rRNA-based phylogenetic analyses which support the previously suggested existence of a sponge-specific microbiota. These analyses provide a suitable vantage point from which to consider the potential evolutionary and ecological ramifications of these widespread, sponge-specific microorganisms. Subsequently, we examine the ecology of sponge-microbe associations, including the establishment and maintenance of these sometimes intimate partnerships, the varied nature of the interactions (ranging from mutualism to host-pathogen relationships), and the broad-scale patterns of symbiont distribution. The ecological and evolutionary importance of sponge-microbe associations is mirrored by their enormous biotechnological potential: marine sponges are among the animal kingdom's most prolific producers of bioactive metabolites, and in at least some cases, the compounds are of microbial rather than sponge origin. We review the status of this important field, outlining the various approaches (e.g., cultivation, cell separation, and metagenomics) which have been employed to access the chemical wealth of sponge-microbe associations.

“…The sponges A. fulva, N. subtriangularis, and N. erecta were collected at depths of 2-5 m near the Bocas Research Station of the Smithsonian Tropical Research Institute (STRI; Bocas del Toro, Panama). These sponge species are dominant members of the reef community at their respective locations (Olson et al 2006;Erwin and Thacker 2007) and all have a rope-like growth form that is ideal for attaching to artificial substrates. A shading experiment using A. cauliformis was conducted at Big Point, a 3-4-m-deep site north of CMRC in May 2009.…”

To investigate the importance of symbiont-derived nutrition to host sponges, we coupled manipulative shading experiments with stable isotope analyses of isolated symbiont and host cell fractions. Experiments were conducted with four common reef sponges: Aplysina cauliformis, A. fulva, Neopetrosia subtriangularis, and Niphates erecta. The sponge N. erecta lacks photosymbionts, had a higher growth rate under shaded conditions, and displayed no difference in chlorophyll a (Chl a) concentrations across treatments. Isotope values suggested that this sponge obtains nutrition from particulate organic matter in the water column. In contrast, sponges hosting cyanobacterial symbionts (Aplysina spp. and Neopetrosia) had lower growth rates and lower Chl a concentrations under shaded conditions, suggesting that these hosts rely on photosymbiont nutrition. d 15 N and d 13 C values of sponge and microbial cell fractions demonstrated that, while both carbon and nitrogen are transferred from symbionts to host cells in A. cauliformis, only carbon is transferred in N. subtriangularis, and only nitrogen is transferred in A. fulva. Under shaded conditions, shifts in symbiont d 13 C values were coupled to shifts in host d 13 C values in some, but not all, host species, suggesting that the stability of these interactions varies across host species. Symbiont-derived nutrients are transferred to the cells of host sponges, and the variability observed among host species indicates that these interactions are more complex than originally hypothesized.
