| Abstract | Resumen. Se estudia la influencia del tipo de sedimento y la profundidad en la distribucion y desarrollo del foraminifero bentonico Nonionella auris (d’Orbigny). Se analizaron muestras de sedimentos superficiales provenientes del golfo San Matias, provincia de Rio Negro, Argentina. Los estudios cualitativos, cuantitativos y estadisticos realizados sugieren que sitios con mayor profundidad, mayor contenido de fango y bajo nivel de energia propiciarian el desarrollo de esta especie. Abstract. DISTRIBUTION OF NONIONELLA AURIS (D´ORBIGNY) (FORMINIFERIDA) IN SAN MATIAS GULF, RIO NEGRO PROVINCE, ARGENTINA. Qualitative, quantitative and statistic analysis on samples of surface sediments from San Matias Gulf, Rio Negro Province, Argentina, reveal a relationship between the type of substrate-depth and characteristics and distribution of the benthic foraminifer Nonionella auris (d´Orbigny). The study suggests that the development of this species is favoured in low energy and deep environments with muddy substrates. |
