Descripción de artrópodos epigeos en dos ambientes del Parque Nacional Talampaya, La Rioja, Argentina.

This Project studies the biodiversity composition of epigean artrhropods in two habitats of the Talampaya, National Park, La Rioja,Argentina. The two studied habitats are different in the composition and vegetational structure. The habitats were designed as follow: “Site A”: poor in organic matter with scare development and structure of the soil; “Site B”: is structured soil with morefloristic richness.The diversity of the epigean arthropods was considered using pit-fall trapping that gives good information about diversity of the epigean arthropods. Twenty pit-fall traps were put on each site according with the follow design: 4 traps arranged into 5 rows, separated each trap by 5 meters considering this distance between the rows and the traps. The traps were filled with a water solution with drops of detergent. The traps were active during 2 days on each season during one year, and revised three times by day: between 8:00-10:00AM; 2:00-4:00PM and 6:00-8:00PM. The statistical analysis was carried out using the software InfoStat 2004.Two thousand three hundred and eighty five epigean arthropods of 15 orders were collected at the Talampaya National Park. Both studied sites were different in the epigean arthropod composition community in species diversity, maybe this will be relationship with the variation of the vegetation structure and the soil composition of each sites. According with them, both habitats are important to conserve in theTalampaya National Park, La Rioja (Argentina), because the have a complementary fauna.Este proyecto estudia la biodiversidad y la composición de los artrópodos epigeos en dos ambientes aparentemente diferentes en cuanto a estructura y composición de la vegetación en el Parque Nacional Talampaya, La Rioja, Argentina. Los hábitat fueron designados como: “Sitio A” (pobre en materia orgánica con escaso desarrollo y estructura del suelo); y el “Sitio B” (con sueloestructurado con mayor riqueza florística).La diversidad fue considerada usando trampas de caída que proveen buena información sobre la diversidad de los artrópodos epigeos.Veinte trampas de caída fueron colocadas en cada sitio de acuerdo con el siguiente diseño: 4 trampas dispuestas en 5 filas, separadas cada trampa por 5 metros, considerando esta distancia entre las filas y las trampas. Las trampas fueron llenadas con una solución de agua y gotas de detergente, y estuvieron activas durante 2 días en cada estación a lo largo de un año, siendo revisadas tres veces al día: entre las 8:00-10:00AM; 2:00-4:00PM y 6:00-8:00PM. Los análisis estadísticos fueron realizados por medio del software InfoStat 2004.Dos mil trescientos ochenta y cinco artrópodos fueron colectados en el Parque Nacional Talampaya, correspondiente a 15 órdenes. Ambos sitios estudiados fueron diferentes en la composición de artrópodos epigeos en cuanto a la diversidad, posiblemente relacionado con la variación en la estructura de la vegetación y en la composición del suelo de cada sitio. De acuerdocon ello, ambos hábitats son importantes conservar en el Parque Nacional Talampaya, La Rioja (Argentina), debido a que ellos son complementarios en fauna
