Resumen

FIERRO TAPIA, Andrés; ZUNIGA ALVAREZ, Alfredo; AGUILERA PUENTE, Alfonso  y  REBOLLEDO RANZ, Ramón. Carabids (Coleóptera: Carabidae) present in a vegetation relict of the central valley of the Araucanía Region of Chile. Idesia [online]. 2011, vol.29, n.3, pp.87-94. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292011000300013.

A study was conducted on the diversity of epigeic Carabids and their presence in the relic forest of Rucamanque, a priority area for conservation and biodiversity. Pitfall traps were installed in the forest of Aextoxicon punctatum (olivillo) and Nothofagus obliqua (roble) and also its natural ecotone, in November 2005 and January 2006. The abundance, richness and diversity were analyzed. In total 1,101 carabids were collected, all belonging to 12 native species. Ceroglossus chilensis gloriosus, C. magellanicus similis and Parhypates extenuatus composed 93% of these samples. During the study, a high concentration of epigeic Carabids of both species of Ceroglossus were present in the olivillo forest. The accumulation of species, their richness and diversity indicated that the ecotone of the Rucamanque forest had the highest level of diversity.
