Asociaciones de Foraminíferos bentónicos en los sedimentos recientes del estuario de Tina Mayor (Asturias-Cantabria)

A total of 35 species of benthic foraminifers have been taxonomically determined in recent sediments of the Tina Mayor estuary (Asturias-Cantabria provinces, N. Spain). Alive individuals belonging to 22 species, reach up to 30.2% of the total obtained specimens. Most abundant species in both bioceno...
