Resumo
Bats were captured with mist-nets for 36 days along one year in the legal reserve of Anglo American Brasil/Codemin, in the municipality of Niquelândia, north of Goiás State. Three areas of three different fitofisionomias were inventoried: Dry Forest, cerrado and cerrado stricto sensu. Three expeditions were accomplished in the dry period and three in the rainy period during the new moon phase. Seven hundred and twenty-five bats belonging to nineteen species were recorded: Carollia perspicillata, Glossophaga soricina, Platyrrhinus lineatus, Pteronotus parnellii, Anoura geoffroyi, Desmodus rotundus, Molossops temminckii, Micronycteris minuta, Lonchophylla dekeyseri, Artibeus planirostris, Artibeus cinereus, Diphylla ecaudata, Platyrrhinus helleri, Lophostoma brasiliense, Artibeus concolor, Artibeus lituratus, Mimon bennettii, Phyllostomus discolor e Phyllostomus hastatus. The family Phyllostomidae represented 95,8% of the captures; the family Mormoopidae 3,0%, and Molossidae 1,2%. Carollia perspicillata was the dominant species (64,4%% of the sample) , followed for Glossophaga soricina (20%). The research still raised the presence of the one species threatened of extinction Lonchophylla dekeyseri. Artibeus concolor was recorded for the first time to Central Brasil. The Shannon-Wienner index (H') and Eqüitabilility (E) calculated for the areas it was: forest: H' = 0,716 E: 0,3260); cerrado area: H'=1,456 (E: 0,5677) and cerrado stricto sensu: H'=1,397 (E: 0,6068). The largest abundance was observed in the riverine forest (54,4%) and the largest number of species in the cerrado (13 species). Frugivorous species were predominantly in this study. The most similar areas were the two cerrado areas. It was observed a seasonal variation with relationship to the number of captures of bats, with a larger frequency observed in the rainy period. The three nectarivorous species found had picks of annual activities. The pattern of occurrence of species taxonomic or ecologically related revealed that P. lineatus and C. perspicillata didn't demonstrate correlation in the pattern occurrence (r = 0.72; p = 0,106) and a positive correlations were found for: M. minuta and M. temminckkii (r=0,917; p <0,05); M. minuta and P. parnellii (r=0,157; p=765); P. parnellii and M. temminckkii (r=-0,025; p=0,96). The study demonstrated that reserves legal of Anglo American Codemin it can be considered quite several when compared to other areas of Cerrado
