Abstract

Urban landscapes harbor diverse man-made land-uses ranging from highly modified residential and industrial areas to semi-natural habitats with their associated biotic communities. Understanding the ecological patterns and processes of urban landscapes is required for the maintenance of urban biodiversity and planning in the face of expanding cities and increasing populations. Therefore, we studied the epigeic beetle communities in Bangalore city (India) to examine their responses to different types of urban land-uses. They were systematically sampled using pitfall traps from four land-use types (remnant forest patches, campuses, public parks and vacant residential plots). Different taxonomic groups within the epigeic beetle communities dominated different land-use types. In general, the alpha diversity was higher in residential plots and remnant forest patches than parks and campuses, indicating their differential responses to habitat disturbance. The overall beta diversity was high, with moderate levels of similarity between the sampled locations indicating spatial heterogeneity of urban environments. Among trophic guilds, predators and detrivores dominated residential plots and remnant forest patches, respectively. Finally, we conclude that future urban planning in Bangalore should include even small patches of natural vegetation for conservation of native flora and fauna, as these small patches can provide refuge to native biotic communities, including insects.
