Among the phyllostomids there are reports of folivory in the genera Artibeus and Platyrrhinus, based on opportunistic observations. Here, we conducted behavioural sampling using camera-trapping in the roost of a colony of Platyrrhinus lineatus already known to consume leaves during the dry and wet seasons, in order to investigate the frequency of leaf consumption, as well as eventual seasonal differences. We observed feeding activity in 80.5% of sampling nights, where fruit was present in 90.3% and leaves at 80.6%, with no significant differences between the consumption of items. When analyzing video recordings, we observed feeding activity in 22.2% of the samples, in which the consumption of fruits was significantly more frequent than the consumption of leaves. We also observed seasonal variation, with the consumption of leaves bein...

study aimed at surveying the bat species in a southwest area of Goiás. Mist
nets and manual nets were used to capture the bats. After a 13.752 m2h net
sampling effort and three visits to shelters, we captured 141 bats belonging
to three families, six subfamilies, and 13 species. The Phyllostomidae family
showed the highest number of species (11). Fruit bats were the most commonly
sampled, 103 individuals and six species were captured. The most commonly
captured bat species was Carollia perspicillata (n = 45). All the bat species have
already been registered in Goiás. The number of bats in this study corresponds
to 12,6% of the Cerrado species and for this microregion.

Nevertheless, studies on bats in these environments are extremely scarce and fragmented. This study characterized the chiropteran fauna from two sandstone caves under the influence of the Belo Monte hydroelectric dam (Belo Monte UHE) in Pará, Brazil. The Kararaô and Kararaô Novo caves are located on the same ridge, 250 m apart. Three expeditions were carried out in 2013 and 2014, with a 4- to 5-month interval in between. A total of 589 animals were caught, 246 in the Kararaô cave and 343 in the Kararaô Novo cave. Fifteen species were recorded (13 in each cave) representing 79% similarity. With the exception of Vampyrum spectrum, which is not a cave species, the remaining recorded species were mostly cave bat species. Some species seemed to use the caves seasonally, although the basis of this pattern is still unknown. The most commonly observed species were Pteronotus personatus (dominant in the Kararaô cave), P. parnellii (dominant in the Kararaô Novo cave), and Lionycteris spurrelli, which accounted for 65% of all captures recorded for the two caves. Natalus macrourus is a species recorded in the Kararaô cave that is regionally threatened with extinction. Both caves are less than 500 m from the future reservoir; however, because the Kararaô cave entry is in an area that is lower than the reservoir, it can suffer alterations that would affect its dynamics. This raises great concern about the cave’s associated fauna.

Herein we report two new occurrences of phyllostomids bats (Mesophylla macconnelli and Artibeus concolor) in the savanna habit (cerrado) in west-central Brazil. Mesophylla macconnelli was collected in the protected area of a private natural heritage reserve (Reserva Particular do Patrimônio Natural Pousada das Araras), in Serranópolis municipality, Goiás state. Artibeus concolor was trapped near Serra da Mesa reservoir, in Niquelândia municipality, Goiás state. These records enlarge considerably the south distribution of the two species.
