Foramíferos Textuláridos en sedimentos someros recientes de la Península Antártica y su relación con el área Subantártica Sudamericana

forty nine samples, of superficial marine sediments (< 50m.) from 3 localities: deception island, chile bay and fildes bay, antarctic península were analysed in order to investigate the foraminiferers of suborder textulariina delage y herouard, 1886. twenty two species were identifed and classiffed en 12 families and 15 generas. the most abundant species were trochammina malovensis (53,2%), milia-mmina arenácea (16,3%) y reophax dentaliniformis (6,7%). deception island contributed with most of the specimens (57%) and chile bay with the highest number of species. thes most common species in the area were trochammina malovensis (95,9% of the samples), miliammina arenácea (73,5%), spiro-plectammina biformis (63,3%) and trochammina squamata (61,2%). hierarchical cluster analysis and anosim showed there is not communities differences between bays. ten species (from 22) could not be found in the southernmost southamerica: alveolophragmiun columbiense, deuterammina glabra, eggerella minuta, pseudobolivina antarctica, reophax nodulosus, rhabdammina linnearis, saccam-mina sphaerica, textularia wiesneri, trochammina malovensis and t. quadriloba. probably they are endemic species for the antarctic region.
