| contents | Diversity and aggregation areas of planktonic cnidarians of the southern channels of Chile (Boca del Guafo to Pulluche Channel) Daniela Soto Sergio Palma Pedro Apablaza Ciencias de la Tierra Chile diversity cnidarians distribution southern channels We identified 36 species of cnidarians (27 hydromedusae, 9 siphonophores) collected from the Moraleda,King, Darwin, and Pulluche channels, located in southern Chile. The hydromedusae Gossea brachymera, Hybocodonunicus, and Sarsia coccometra, and the siphonophores Rosacea cymbiformis and R. plicata were recorded for the firsttime in the southern channels. Diversity values were higher for Hydromedusae (2.66 bits) than for Siphonophorae (1.15bits). The largest aggregates were found in the Moraleda and Pulluche channels, with densities that exceeded 7,000ind·1000 m-3. The vertical distribution of the dominant species showed Solmundella bitentaculata to be located near thesurface (0-20 m), whereas Sphaeronectes gracilis, Muggiaea atlantica, Clytia simplex, and Proboscidactyla ornata werefound in subsurface waters (20-50 m) and Amphogona apicata in deeper waters (50-100 m). According to the Pearsonanalysis, salinity correlated positively with S. gracilis and S. bitentaculata and negatively with P. ornata. C. simplex wasindirectly associated with temperature and the dissolved oxygen concentration. 2007 artículo científico 0716-1069 https://www.redalyc.org/articulo.oa?id=45635208 en http://www.redalyc.org/revista.oa?id=456 Investigaciones Marinas application/pdf Pontificia Universidad Católica de Valparaíso Investigaciones Marinas (Chile) Num.2 Vol.35 |
