Resumen:
The forests of Northwestern Argentina are among the richest and most diverse in the country. For decades the human activities have affected large areas with a great negative impact on their flora and fauna. However our study site, Finca Las Capillas, have an excellent status of conservation, because for more than 50 years the access to humans activities has been restricted, diminishing the antropic effects on the wildlife. We present the results of 12 surveys developed between 1996 and 2012. Bats were collected with mist-nets placed inside vegetation, over ponds and close to water. Species accumulation curve was calculated with EstimateS program to determinate if the surveys were representative. Three estimators of species richness were used: Chao 1, Jackknife 1 and MMMeans. The Shannon and Simpson diversity indices were calculated to analyze and describe the diversity of the area. Twenty four species were recorded, representing the four families of Argentina, of which 51% belongs to Phyllostomidae; the sample contains species of all trophic guilds, being the insectivores the most abundant. Several species represent the first record for Argentina, and are not known elsewhere in the country. The Shannon index was 3.37, high in comparison with other localities. It is fundamental that this area continues to be restricted to human use, a reason for which was recently declared as AICOM (Important Area for Conservation of Bats) with the support of the PCMA (Program for Bat Conservation in Argentina) and RELCOM (Latin-American Bat Conservation Network) as a first step for its protection.
