Ecological aspects of artibeus lituratus e artibeus planirostris (Chiroptera, Phyllostomidae) in Cerrado environments, Mato Grosso - Brazil

Abstract

The present study analyzed the ecological and biological aspects of Artibeus lituratus and Artibeus planirostris captured in the municipality of Nova Xavantina, Mato Grosso, Brazil.  The samplings occurred from January/2010 to December/2010 and from August/2012 to July/2013, in three areas of Cerradão and three of Cerrado stricto sensu.  A total of 286 specimens of Artibeus lituratus (183 females and 103 males) and 103 of Artibeus planirostris (59 females and 44 males) were captured. Among the environments, greater abundance was recorded in the Cerrado stricto sensu.  For both species, there was a significant relationship when analyzing the abundance between seasons, and in the rainy season, there was greater abundance. There was also a correlation between the activity schedule of the individuals and the abundance that was verified by the Rayleigh test. The correlation test between temperature and abundance variations showed significant values. The forearm and weight measurements showed positive results with the performance of the correlation test.  This work contributed to expanding the knowledge of bats in the eastern region of Mato Grosso itself, there is little information regarding the ecological and biological aspects of Artibeus lituratus and A.  planirostris in the region.
