Última Sponge interactions with spatial competitors in the Spermonde Archipelago Naturalis Voogd, N.J. de; Becking, L.E.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van. This study describes the in situ effects of four bioactive sponges on their neighbours at three different locations and two depths in the Spermonde Archipelago, SW Sulawesi, Indonesia. The natural rates of interaction between the sponge species and eight possible competitive invertebrate groups were defined and quantified in circular subplots, this was repeated 25x for each of the four species and for each location and depth. Most interactions occurred with other sponges and with corals. Coral overgrowth by the four target species caused necrosis in more than 85 % of these interactions, whereas this was less than 25 % in sponge overgrowths. These results suggest that the toxins are used in spatial competition and that the concentrations of the bioactive...

Ano: 2003 URL: http://www.repository.naturalis.nl/record/268614 Sponge beta diversity in the Spermonde Archipelago, SW Sulawesi, Indonesia Naturalis Voogd, N.J. de; Cleary, D.F.R.; Hoeksema, B.W.; Noor, A.; Soest, R.W.M. van. Sponge assemblages were investigated in the Spermonde Archipelago, southwestern Sulawesi, Indonesia. In this study spatial patterns of sponge similarity among sites were significantly related to remotely sensed environmental variables, the degree of human settlement and depth, but not to the distance between sites. Both oviparous and viviparous species groups responded to similar environmental constraints, and differences in similarity were unrelated to the distance between sites. The degree of human settlement, however, was significantly related to variation in the composition of viviparous, but not oviparous species. Our results demonstrate, most importantly, the utility of remotely sensed data in predicting the spatial turnover of diverse species...
