Mean volume gain was only used for the 2015–2016 sampling event due to the small sample size of Ridge 1 sponges between 2014 and 2015. has been poorly studied despite being widespread across the region and likely to fulfil similar functional roles.

We have monitored permanent plots on reefs off Key Largo, Florida, USA, to study the demography of a particularly important species, the giant barrel sponge, Xestospongia muta. PubMed  Jackson, J.

Sponge abundance, diet, feeding efficiency, and carbon flux. Surviving in a marine desert: the sponge loop retains resources within coral reefs. Bunodeopsis globulifera The authors declare no competing interests. Benzekry, S. et al. Correspondence to 1). Molecular analyses are required in order to clarify this issue and fully describe the nature of the species complex. Wellingt. We then used our size-at-age model to estimate the approximate age of the sponges on the wreck and compared these to the known maximum possible sponge age. Thacker, R. W.

However, these processes are not independent of the environment and are likely to be influenced by a range of abiotic and biotic factors6. It is possible that the timeframe of the present study was not adequate to detect periods of rapid adaptive growth during less stressful conditions. Article  Webster, N. S., Cobb, R. E. & Negri, A.

Observations of growth, dispersal and population dynamics of some sponges in McMurdo Sound, Antarctica. Rather than making an arbitrary choice a priori and identifying the “best” candidate model(s), multi-model inference (MMI) using model averaging can be used to estimate parameters from multiple or an entire set of candidate models in order to reduce selection uncertainty32. After the growth rate at each site was considered independently by calculating unique Akaike weights, multi-model inference (MMI) with model averaging was utilized for each site (detailed in the Supplementary Information).Then, in order to quantify the influence of site on Xestospongia spp. Specific growth rates (SGR) from 2014–2016 were used as it was the longest available time interval.

Sponges were collected along a depth gradient at Little Cayman (LC) and Lee Stocking Island (LSI), and the microbiome of these samples was analysed using 16S rRNA amplicon sequencing.

From 2015–2016, however, the volume gained at Kaledupa Double Spur was over eight-fold larger than the volumes reported in the Caribbean22 (40,676.99 ± 12,479.05 cm3), though highly variable. is examined by quantifying individual growth parameters and density across sites. Here we estimated important life history characteristics for Indo-Pacific Xestospongia spp. These earlier experimental results combined with our relatively fast growth rate estimates suggest barrel sponges may be more resilient to some environmental impacts, particularly increased sedimentation and turbidity, than might be expected, and may actually benefit from these conditions in some circumstances. PubMed CrossRef PubMedCentral Google Scholar Negative SGRs were confirmed from photographs and were only removed from analyses were they severely damaged or demonstrating severe necrosis. To obtain Reduced diversity and high sponge abundance on a sedimented Indo-Pacific reef system: implications for future changes in environmental quality. Funct. Adviser: Russell Hill, Institute of Marine and Environmental Technology. density varied significantly across sites around Hoga Island and across the wider Wakatobi Marine National Park (one-way ANOVA: F2,7 = 3.889, P = 0.008; n = 268). Sponges were collected along a depth gradient at Little Cayman (LC) and Lee Stocking Island (LSI), and the microbiome of these samples was analysed using 16S rRNA amplicon sequencing. Growth models are widely used to describe increases in size or volume over time, particularly in fisheries biology30. The oldest giant barrel sponge found off the coast of Venezuela and estimated to be 2300 years old died from SOB in only a few weeks. Article  Limnol. Variation in age extrapolated from growth model projections is not uncommon due to differences in model selection, sampling methods, reproductive life history or morphological differentiation57; the importance of model choice and parameter uncertainties are detailed in the Supplementary Information. Sponges are potentially very long-lived (McMurray et al. We assessed Indo-Pacific barrel sponge demography with a focus on specific growth rate (SGR), density, and mean volume across four sites of varying habitat quality. & Zabala, M. Growth dynamics in four Mediterranean demosponges. The role of sponge competition on coral reef alternative steady states. This is particularly the case for sedimented habitats, although there may be energetic costs associated with living in these suboptimal conditions that negatively impact growth rates. Mar. McMurray, S. E., Pawlik, J. R. & Finelli, C. M. Demography alters carbon flux for a dominant benthic suspension feeder, the giant barrel sponge, on Conch Reef, Florida Keys. 52, 293–303 (2001). Previous research on barrel sponges suggests that they should be susceptible to environmental disturbance. Working off-campus? As we were unable to differentiate which species were surveyed, and due to the demographic nature of the study, all sponges were treated at the level of genus.

Pumping rates of the giant barrel sponge, Xestospongia muta on Caribbean reefs: size scaling, environmental controls, and bleaching effects Sponges are among the dominant organisms on coral reefs in terms of diversity, numerical abundance, and biomass. Sites with the highest sponge densities were Buoy 1, Sampela 1, and Karang Gurita, with densities of 0.017, 0.014, and 0.013 sponges m−2, respectively, followed by Ridge 1 (0.006 sponges m−2), Kaledupa Double Spur (0.005 sponges m−2), Wanci (0.004 sponges m−2), and Tomea (0.002 sponges m−2).
