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.
