Abstract

Resumen. Se estudia la influencia del tipo de sedimento y la profundidad en la distribución y desarrollo del foraminífero bentónico Nonionella auris (d’Orbigny). Se analizaron muestras de sedimentos superficiales provenientes del golfo San Matías, provincia de Río Negro, Argentina. Los estudios cualitativos, cuantitativos y estadísticos realizados sugieren que sitios con mayor profundidad, mayor contenido de fango y bajo nivel de energía propiciarían el desarrollo de esta especie. Abstract. DISTRIBUTION OF NONIONELLA AURIS (D´ORBIGNY) (FORMINIFERIDA) IN SAN MATÍAS GULF, RÍO NEGRO PROVINCE, ARGENTINA. Qualitative, quantitative and statistic analysis on samples of surface sediments from San Matías Gulf, Río 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.
