Ground aracnofauna (Araneae: Araneae) in native and exotic Forest and grasslands of San Martín Park, Entre Ríos, Argentina
Ground aracnofauna (Araneae: Araneae) in native and exotic Forest and grasslands of San Martín Park, Entre Ríos, Argentina. The Exotic plant species invasion in the Argentine Espinal region causes a changein the appearance of the landscape, altering the environment and producing a significant loss of biodiversity. We studied the composition of ground spiders in Parque General San Martín, Entre Ríos, during the summerand winter seasons of 2012. Three areas were selected: pajonal (P), native forest (BN) and exotic forest (BE), pitfalls were used for sampling. A total of 1398 spiders (26 families and 120 species/morphospecies) werecollected. The most abundant families in the different areas were Lycosidae (n=574; 41.06%), Tetragnathiidae (n=223; 15.95%) and Linyphiidae (n=137; 9.80%). The guild category “ground hunters” (n=632) “sheet webweavers” (n=262) and “orb webs weavers” (n=244) were highly represented in all sampling areas. Diversity indices showed that BN was more diverse than P and BE. Complementarity values obtained between P andBE and BN were higher than 71%, while BE and BN showed values of 63%. This study constitutes the first record of the spider´s community of Parque General San Martín.

La invasión de especies leñosas exóticas en la región argentina del Espinal provoca un cambio en la fisonomía del paisaje ya que altera el ambiente y produce la pérdida de biodiversidad. Se estudió la composición de arañas asociada al suelo del Parque General San Martín, Entre Ríos, durante el verano e invierno de 2012. Se seleccionaron tres ambientes: pajonal (P), bosque nativo (BN) y bosque exótico (BE), y se utilizaron trampas de caídas para el muestreo. Se recolectaron en total 1398 arañas (26 familias y 120 especies/morfoespecies). Las familias más abundantes en los tres ambientes fueron Lycosidae (n=574; 41.06%), Tetragnathiidae (n=223; 15.95%) y Linyphiidae (n=137; 9.80%), respectivamente. Los gremios que presentaron la mayor abundancia fueron "cazadoras corredoras sobre suelo" (n=632), "tejedoras de telas en sábanas" (n=262) y "tejedoras de telas orbiculares" (n=244), representados en todos los ambientes estudiados. Los perfiles de diversidad indicaron que el BN fue más diverso que el P y el BE. Los valores de complementariedad mostraron una diferencia de 71% entre P-BE y P-BN, y de 63% entre BE-BN. Este trabajo constituye el primer registro sobre la comunidad de arañas de suelo del Parque General San Martín.
