& Morris, W. F. Predicting changes in the distribution and abundance of species under environmental change. However, it is currently unknown whether such characteristics are applicable to Xestospongia spp. Studies of Caribbean X. muta suggest they may be up to 1000 s of years old. 24, 699–711 (2011). 2. Biol. Growth curves, however, allow for the intrinsic variability of inter-individual differences in size36. Aquat. Values are reported ± standard error (SE) throughout. Article Hydrobiol.

View the article PDF and any associated supplements and figures for a period of 48 hours. Limnol. Significant effects were investigated further with Tukey post-hoc tests. Demogr. We therefore consider our results to provide conservative growth estimates due to the potential for overestimation of volume at the time of larval settlement. Elephants born in the high stress season have faster reproductive ageing. PubMed Google Scholar. PubMed Central Bartholomea annulata. 84, 146–166 (2006). Statistically significant shifts in community structure and dissimilarity (∼ 40%) were detected from 10 to 90 m in LC sponges, but a similar shift was not identified in sponges from 10 to 60 m at LSI (only 17% dissimilar). The range of SGRs herein was also larger (−0.12–6.24 yr−1 as compared to 0.02–4.04 yr−1 in the Caribbean)22. Estuar. The functional roles of marine sponges. McMurray, S. E., Johnson, Z. I., Hunt, D. E., Pawlik, J. R. & Finelli, C. M. Selective feeding by the giant barrel sponge enhances foraging efficiency. Size is typically related to life-history processes such as mortality, growth and reproduction4, as well as its spatial competitiveness5 and ability to consume resources. Google Scholar. Turon, X., Tarjuelo, I. The Caribbean barrel sponge, Xestospongia muta, is a large and common member of the coral reef communities at depths greater than 10 m, and has been called the “redwood of the deep”. Combining the sites for model averaging, however, resulted in a larger sample size (n = 121), which is in line with previous studies22. PubMed Central However, we did find a number of barrel sponge recruits during our study challenging this suggestion, although supply was sporadic. Shelf Sci. Abdo, D. A. et al. and you may need to create a new Wiley Online Library account. Some degraded reefs are characterized by high levels of sedimentation and low coral cover in this area, but support large populations of the ecologically important giant barrel sponge Xestospongia spp. Mortality estimates were possible only at Buoy 1 and Sampela 1 and were variable; the highest mortality recorded was 11 individuals in one year (Sampela 1, 2014) and the lowest 3 (Buoy 1, 2015). activity of the giant barrel sponge, Xestospongia muta Holobiont: molecular evidence for metabolic interchange. This research was funded by a Victoria University of Wellington Doctoral Scholarship awarded to Emily McGrath. An organism’s lifespan, along with its population and individual growth rate, can potentially be used to predict its resilience to environmental disturbance or exploitation7. There are further examples where large sponge size does not correlate with long life in sponges. A repeated measures two-way ANOVA was used to examine the effect of site and year on mean sponge volume. In this study, the relationship between the metabolome and the geographical location of sponges within the genus Xestospongia spp. growth rates, a second model analysis approach was taken. Publisher's note: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. One hundred and thirty-nine specimens of giant barrel sponges However, while the growth curve in the present study reflects a similar shape to that reported in the Caribbean22, Indo-Pacific barrel sponges appear to increase in size more rapidly in the same time frame. Ecol. Furthermore, there are several potential explanations for the disparity between Caribbean and Indo-Pacific SGRs. B. C. & Buss, L.

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.
