A high resolution shapefile of the Andean biogeographical region.

Biogeographical analyses have proven to be an efficient complement to classic ecology. An ecoregional layer based on Morrone understanding of the Andean region and its sub-regions was constructed. This high-resolution layer was generated with GIS software, and it enables to include ecoregions as categorical variables into species distribution modeling software.

Track analysis of Oribatid mites (Acari: Oribatida) of the Subantarctic subregion of South America.

We analysed distributional data of 30 species of Oribatid mites of the Subantarctic subregion of southern South America in order to contribute to elucidate their biotic evolution. We constructed individual tracks for the species analysed, based on published and unpublished records. After superposing them we obtained six generalized tracks and five nodes.

[Toxic fungi in Buenos Aires City and surroundings].

In Facultad de Ciencias Exactas y Naturales,Universidad de Buenos Aires there is a service called Servicio de Identificación de Hongos Tóxicos, directed by researchers of the Program of Medicinal Plants and Fungi Involved in Biological Degradation (PROPLAME-PRHIDEB, CONICET) that assist hospitals and other health establishments, identifying the different samples of fungi and providing information about their toxicity, so that patients can receive the correct treatment. The objective of the present study was to analyze all the cases received from 1985 to 2012. This analysis permitted the confection of a table identifying the most common toxic species.
