“…These findings leave little doubt that the symbiosis between yeast and Chondrilla is not limited to the Caribbean area, but also occurs in the Mediterranean and the Australian Pacific and involves at least three sponge species. Interestingly, although C. nucula has traditionally been described as a cosmopolitan species, several independent studies have suggested that at least the Caribbean and Mediterranean populations are unlikely to be conspecific (Klautau et al, 1999;Usher et al, 2004c). In the Caribbean, this thickly encrusting sponge is common in reefs, where in some areas it can occupy a large percentage of the available hard substrata and even overgrow living corals (Maldonado et al, 2005).…”

Abstract. The detection of an endosymbiotic yeast in demosponges of the genus Chondrilla described here records the first such association within the phylum Porifera. The symbiont, interpreted as a yolk body in previous ultrastructural studies, is a chitinous-walled fission yeast. Chitin was detected by an immunocytochemical technique that labels its ␤-1,4-N-acetyl-D-glucosamine residues. Abundant symbiotic yeast cells (4.4 Ϯ 2.3 cells per 10 m 2 ) transmitted from the soma through the oocytes to the fertilized eggs are directly propagated by vertical transmission in the female. Vertically transmitted yeast were detected in three Chondrilla species with disjunct biogeographical distributions: the Mediterranean, the Caribbean, and the Australian Pacific. Apparently these yeasts are not present in other demosponge genera. Therefore, the fungal endosymbiosis most likely evolved before or during the diversification of the genus Chondrilla.

“…Sequence data for these specimens could not be obtained, but a large geographical disjunction occurs between the tropical C. grandistellata (Indonesia) and the temperate C. secunda (south coast of Australia), as well as the differences in spicule sizes and morphologies, therefore we consider C. secunda to be a valid temperate species. Sequencing of rDNA of nine specimens of Chondrilla secunda showed close molecular similarity between all specimens (Usher et al 2004a), with up to 99.5')/0 sequence identity.…”

“…There have been many studies on sponges describing spatial variability in genetic structure [14][15][16][17][18][19]; biochemical composition [20,21]; morphology [22]; and distribution patterns of specific species [23][24][25]. Spatial variation in abundance and diversity have also been reported at different levels: within a particular habitat -alpha diversity [26][27][28][29]; variation within geographic areas -beta diversity [3,5,[30][31][32]; and variability across different geographic regions -gamma diversity [33][34][35][36].…”

Spatial Variability of Sponge Assemblages on the Wellington South Coast,New Zealand

Abstract:The aim of this study was to provide baseline data for sponge biodiversity on the Wellington South Coast, New Zealand. Eighteen sites were qualitatively sampled resulting in the identification of 65 different sponge taxa. Forty-three of these species were also reported from a quantitative survey of three vertical wall sites in 8-10m depth conducted as part of a long-term monitoring study. All three sites had a similar mean number of species per quadrat, however, the percentage cover of sponges and sponge density varied significantly between sites. ANOSIM showed that all three sites were significantly different from each other (P<0.001), which is likely the result of differences in environmental conditions. The Wellington South Coast has a diverse sponge assemblage, which is atypically dominated by calcareous species of the genus Clathrina. This appears to be unusual for New Zealand, and although the reasons for this situation are unknown, we hypothesise that this situation is explained by the low levels of nutrients on the Wellington South Coast, allowing calcareous sponges to proliferate at the expense of the demosponges.
