Resumen
In this work, the recent micromollusc assemblages of the Añavieja springs have been studied, identifying one bivalve (Pisidium sp.) and 12 gastropod species, five of which are terrestrial (Cochlicella sp., Truncatellina cylindrica, Vallonia costata, Vallonia pulchella and Vertigo pygmaea) and the rest are aquatic (Acroloxus lacustris, Ferrissia sp., Gyraulus crista, Gyraulus laevis, Gyraulus cf. crista, Gyraulus sp. and Potamopyrgus antipodarum). According to their distribution in the study area, the streams with some current are unfavourable environments for the malacofauna. The possible anthropic contamination in one of the studied spring does not allow the normal development of these organisms. On the contrary, springs without anthropic influence, more quiet waters and large vegetation cover, are shown like more favourable environments for these micromolluscs. The knowledge of these recent assemblages and the ecological factors that determine their distribution in this area will be used as recent comparison model for possible palaeoenvironmental reconstructions based on malacofauna carried out in this wetland.
