Moluscos aquáticos atuais de ecossistemas costeiros em Imbituba, Imaruí e Laguna, Santa Catarina, Brasil: parâmetro de caracterização para paleoambientes

Abstract

This paper registers 16 species of aquatic molluscs, especially the limnic and estuarine species Heleobia davisi Silva & Thomé, 1985, Heleobia australis australis (Orbigny, 1835) and Erodona mactroides Bosc, 1802, from D'Una river and Mirim, Imaruí and Santo Antônio lagoons and Laguna Beach (Santa Catarina, Brazil). This parameter was very important for the paleoecological analysis conduced for that area, where oscillation of the sea level occurred during the Holocen Period. Heleobia davisi is registered for the first time to the Santa Catarina.
