Resumo
The evaluation of DNA damage was carried out with the comet assay from blood samples of three
bat species sampled at municipal parks of Goiania and Cerrado remnants, located in rural areas of
the municipalities of Bela Vista and Urutaí, Goias state. The species sampled in the urban area
were Artibeus lituratus, Artibeus planirostris and Platyrrhinus lineatus. In non-urban areas, only
Artibeus planirostris was sampled. These frugivorous species are abundant and well adapted to
different environments, including urban and agricultural areas. The remaining vegetation of the
urban environment was very impacted and it was included in the most urbanized area of the city,
with heavy traffic of vehicles, large concentration of buildings and high population density.
Sampling in non-urban environments were held in Cerrado fragments in a rural area surrounded by
pasture and agricultural activities. Thus, the DNA damage found in the urban environment bats
were compared to verify whether there was significant variation among the parks, between species
and if weight influenced the variation of the DNA damage. The DNA damage obtained for A.
planirostris allowed to compare the urban and non-urban environment to identify in which of the
environments this species presented higher DNA damages. The results showed that in the nonurban environment, the DNA damage was higher than in the urban environment being statistically
significant. Moreover, in the urban environment, the increased DNA damage was associated with a
reduction in area of the parks. In general, in the urban environment, the DNA damage may be
linked indirectly to the edge effect and other environmental stressors, while in non-urban
environment, higher levels of DNA damage may be related to pesticides used in the agricultural
activities.
