Abstract
The present study aimed to inventory of bats species present in an urban area, located within the main campus of the State University of Maringá, northwestern Paraná State, and to present data on the diet, reproduction, and activity times of the captured species. Collections were performed monthly, between September 2007 and August 2008, and 377 individuals were captured, belonging to four species from the Phyllostomidae family: Artibeus lituratus (90%), Platyrrhinus lineatus (6.4%), Sturnira lilium (2.4%), and Carollia perspicillata (1.3%). The types of fruit ingested consisted especially of Cecropiaceae, Moraceae, Myrtaceae, Piperaceae and Solanaceae. Among the captured exemplars, 51% were female and 49% male. No pregnant females of A. lituratus or males with descended testicles were captured in autumn, and the largest recorded numbers of these groups were verified in winter. With regard to lactating females, A. lituratus was sampled year-round, with predominance during the warmer season. In spite of the low species diversity, the campus area is used by frugivore species that are generalists and are able to feed and reproduce in urbanized areas. In order to increase that diversity, management programs should be implemented so that urbanization and Chiroptera diversity can coexist with lower risks and losses to ecosystems.
Highlights
Brazil is regarded as one the countries with the world’s greatest biological diversity (MITTERMEIER et al, 2005)
Regional assessments in urban areas, as well as contributions with data on the occurrence of species in altered habitats, with native of introduced vegetation, provide ecological elements that allow a better characterization of the local biodiversity
In order to characterize the different environments present inside the main University of Maringá (UEM) campus with regard to the presence of vegetation and direct human activity, samplings were performed at three sites: 1. Riparian vegetation: Area located in the western end of campus
Summary
Brazil is regarded as one the countries with the world’s greatest biological diversity (MITTERMEIER et al, 2005). Bats are indicators of the levels of habitat degradation, due to the wide variety and abundance of species in neotropical regions (FENTON et al, 1992). Indications of the activity period may aid in the ecological understanding of the species In this context, regional assessments in urban areas, as well as contributions with data on the occurrence of species in altered habitats, with native of introduced vegetation, provide ecological elements that allow a better characterization of the local biodiversity. The present study aimed to make an inventory of bat species present in an urban area, located within the main campus of the State University of Maringá (UEM), in northwestern Paraná state, and present data on the diet, reproduction, and activity times of the captured species
