Diversity of non-marine mollusks in the southernmost Paranaense forest of the world.

The Natural Reserve of Punta Lara (RNPL) is a protected natural area that includes Paranaense forest southernmost in the world. This area is surrounded by a densely populated and touristic sector. The objective of this work was to estimate the richness, diversity and equity of the RNPL mollusks (aquatic and terrestrial) and to establish the relationship of their species in aquatic environments.

Distribution of the Unionida (Bivalvia, Paleoheterodonta) from Argentina and its conservation in the Southern Neotropical Region.

Bivalves are one of the most representative groups in the Phylum Mollusca, with over 1,100 freshwater species around the world except Antarctica. About 900 of these species belong to the Order Unionida Gray, 1854. In South America, the distributional range of the Unionida includes all countries in the region and extends as far south as the lakes and rivers of Argentinean-Chilean Patagonia.

[Terrestrial gastropods from Misiones Province, Argentina].

The Atlantic Forest represents one of the global priority eco-regions for biodiversity conservation. In Argentina, this is represented by the Paranense Forest, which occupies much of the Misiones Province. In this paper, an updated list of land mollusks from Misiones Province is presented, and its species richness was evaluated comparing protected and unprotected areas.
