Última Shallow rocky bottom benthic assemblages as calcium carbonate producers in the Alboran Sea (southwestern Mediterranean) ArchiMer Cebrian, E; Ballesteros, E; Canals, M. Zonation patterns and species composition of the different assemblages encountered along the bathymetric axis are considered in order to quantify the biomass and calcium carbonate content of communities thriving in rocky bottoms of La Herradura (southwestern Mediterranean) between 0 and 50 m depth. Algal biomass is lower but total biomass is slightly higher to values recorded in other Mediterranean areas due to the high biomass of suspension feeders. Since most of the animals and algae with high biomass have calcareous skeletons, the calcimass is rather high (1 100 to 2400 g . CaCO3.m(-2)) when compared to other temperate and Mediterranean sites. A tentative estimate of yearly carbonate production yields 1 000 g . CaCO3.m(-2).y(-1) for the rocky bottoms of...

An extensive survey for freshwater sponges was carried at the temporarely exposed rocky bottoms of river Corumbá at Goiás State and river Manso at Mato Grosso State. The exposure resulted from the closing of the dams for lake formation at the respective Hidreletric Power Plants. Drulia uruguayensis Bonetto & Ezcurra de Drago, 1968, Corvospongilla seckti Bonetto & Ezcurra de Drago, 1966 and Trochospongilla repens (Hinde, 1888) were seen to be common to both rivers. Eunapiusfragilis (Leidy, 1851), Oncosclera navicella (Carter, 1881) and O. petricola (Bonetto & Ezcurra de Drago, 1969) were yet found in river Manso and O. schubarti (Bonetto & Ezcurra de Drago, 1967) in river Corumbá. O. schubarti is redescribed and SEM... Tipo: Info:eu-repo/semantics/article Palavras-chave: Sponges; Oncosclera schubarti; Neotropical; River; Benthic assemblages.
