On the seasonal abundance of two coexisting species of Ceroglossus ground beetle (Coleoptera: Carabidae) from the Katalapi park, south Chile
Abstract
Species abundance is an important ecological parameter that can provide insights on ecological and evolutionary processes. Here, we report patterns of abundance for two coexisting Ceroglossus ground beetle species (C. buqueti and C. darwini) from a Valdivian temperate rainforest area in South Chile, sampled at four time periods within a year. Results show similar overall species abundances, although they varied differently along the year for each species. The abundance of the species C. darwini peaked earlier than the species C. buqueti and it was absent during fall and winter, while C. buqueti was detected at all seasons. Abundances also varied spatially, but they were positively correlated between species suggesting no spatial segregation. Carabidae, Chile, species abundance, Valdivian temperate rainforest.
