The diet, activity and reproductive patterns of several species of bats were investigated in primary forests of Central Amazon. Between August 1996 and August 1997, using mist nets set both at canopy and understorey levels, 936 bats, belonging to 51 species, 31 genera and 6 families were captured. Fecal samples from 35 species were examined, with four food categories and 25 food items identified. Time of captures indicate a wide variation, but the major part of the species presented a peak of activity around the first hour after sunset. Three reproductive peaks were observed: October-November; January-February; and July-August, but reproductive patterns varied among the families. The structure of the bat fauna in Manaus is similar to other sites in the Amazon and Central America, the main common points being: a) a high diversity of bat species, usually more than 40 species representing 6-8 families; b) 3-4 very common and geographically widespread species; c) most species are represented by a few captures; d) frugivorous species dominate the fauna and insectivorous species are less often captured; and e) most species cluster in 2-3 guilds, dominated by small (< 12 g) species.

Effects of different secondary vegetation types on bat community composition in Central Amazonia, Brazil (2010, background): “concolor was associated with its consumption of Vismia fruits, which represented 480% of its diet (Bernard, 2002; Bobrowiec, 2003).”
Species diversity of bats (Mammalia: Chiroptera) in forest fragments, primary forests, and savannas in central Amazonia, Brazil (2002, background): “The interactions involving bats and other species in Brazilian Amazonia have only recently been extensively studied (e.g., Reis and Guillaumet 1983; Uieda and Vasconcellos-Neto 1985; Bernard 1997; Gribel et al. 1999; Bernard 2002).”
Consequences of a large-scale fragmentation experiment for Neotropical bats: disentangling the relative importance of local and landscape-scale effects (2016, methodology): “For instance, ~32000 km of new forest edges are created annually in the Brazilian Amazon by deforestation alone (Broadbent 40 et al 2008) and, in 2000, ~140 x 103 km2 of the region’s land area was composed of regenerating forests (Carreiras et al 2006).”
