“…However, the authors utilize percent cover as an indirect proxy for sponge biomass in their analysis. As discussed by Wulff (2012), and illustrated by our own data from the Bahamas and Chuuk (Slattery & Lesser 2012), sites can exhibit similar sponge percent cover yet have significant differences in sponge biomass due to dissimilarities in sponge growth forms and community composition. To be fair, most studies of sponge community dynamics use this metric, but percent cover cannot be used instead of sponge biomass to infer relationships between food availability and sponge growth.…”

Pawlik et al. (2015; Mar Ecol Prog Ser 519:265−283) proposed 4 hypotheses regarding the influence of food limitation on growth and distribution of Caribbean sponges: (1) increasing sponge cover as particulate organic carbon increases with depth, (2) replacement of high microbial abundance sponges with low microbial abundance sponges at depth, (3) dominance of sponges with photosymbionts above the photosynthetic compensation point, and (4) sponge morphologies that reflect adaptations to feeding. Pawlik et al. (2015) concluded that there is no evidence of food limitation (i.e. bottom-up control), and that predation is the primary process that determines the growth, biomass and biodiversity of sponges on Caribbean coral reefs. Here, we address the conclusions of Pawlik et al. (2015) in the context of the observational, correlational, and manipulative studies they utilized in their analysis. We argue that both top-down (predation pressure) and bottom-up (food limitation) processes influence the distribution of sponges on coral reefs, that these factors vary in time and space, and that only when multifactorial manipulative experiments are undertaken will the magnitude of the roles of predation and food limitation be understood.

“…Since its description, the cyanobacteriosponge, Terpios hoshinota Rützler and Muzik, 1993, has become notorious for overgrowing live corals on shallow reefs in the west Pacific (Fujii et al 2011, Wulff 2012, de Voogd et al 2013, where it may appear as outbreaks, but also can suddenly disappear .…”

“…Marine sponges are filter-feeders found in a wide range of benthic environments, across gradients of depth and latitude (Wulff, 2012). Sponges perform a broad range of functional roles in benthic habitats (Bell, 2008), including the retention of nutrients and energy within the coral reef through the consumption of dissolved organic matter (DOM) and high cell turnover rates (Yahel et al, 2003;de Goeij et al, 2013).…”

Integrated metabolism in sponge–microbe symbiosis revealed by genome-centered metatranscriptomics

Despite an increased understanding of functions in sponge microbiomes, the interactions among the symbionts and between symbionts and host are not well characterized. Here we reconstructed the metabolic interactions within the sponge Cymbastela concentrica microbiome in the context of functional features of symbiotic diatoms and the host. Three genome bins (CcPhy, CcNi and CcThau) were recovered from metagenomic data of C. concentrica, belonging to the proteobacterial family Phyllobacteriaceae, the Nitrospira genus and the thaumarchaeal order Nitrosopumilales. Gene expression was estimated by mapping C. concentrica metatranscriptomic reads. Our analyses indicated that CcPhy is heterotrophic, while CcNi and CcThau are chemolithoautotrophs. CcPhy expressed many transporters for the acquisition of dissolved organic compounds, likely available through the sponge's filtration activity and symbiotic carbon fixation. Coupled nitrification by CcThau and CcNi was reconstructed, supported by the observed close proximity of the cells in fluorescence in situ hybridization. CcPhy facultative anaerobic respiration and assimilation by diatoms may consume the resulting nitrate. Transcriptional analysis of diatom and sponge functions indicated that these organisms are likely sources of organic compounds, for example, creatine/creatinine and dissolved organic carbon, for other members of the symbiosis. Our results suggest that organic nitrogen compounds, for example, creatine, creatinine, urea and cyanate, fuel the nitrogen cycle within the sponge. This study provides an unprecedented view of the metabolic interactions within sponge-microbe symbiosis, bridging the gap between cell-and community-level knowledge.
