Ensamble peridomiciliario de carábidos (Coleoptera: Carabidae) en un talar del sudeste bonaerense, Argentina

摘要: „Our purpose was to perform a research on the peridomestic carabid diversity in Celtis tala Guillies ex Planch forest, at Laguna Nahuel Ruca, Mar Chiquita district. A species inventory and comparison of seasonal variation cumulative richness, as well community structure functional groups were carried out. During one year (March 2008-March 2009), 2588 carabids belonging 63 collected, representing 84%-93% estimated richness. Cumulative richness during spring summer higher than autumn winter (p<0.05). Two species, Argutoridius bonariensis (Dejean) Pachymorphus striatulus (Fabricius), represented total 47% captures dominant all seasons. Concerning trophic guilds, zoophagous more 50% assemblage seasons, while phytophagous omnivorous remained low percentages autumn-winter (<10%); former reached peak (20%), latter (34%). Regarding humidity affinities, mesophilous conformed 70% hygrophilous xerophilous less 20%. We discuss probable causes such wandering through talar stand their simplified surroundings, influence that these factors exert composition ground beetle assemblage.
