| Popis: | ABSTRACT Roosts are a key part of bat species' life stories. Information on roost use enables us to understand the biological processes underlying bat ecology and is crucial with regard to the natural-roost loss and environmental pressures related to habitat destruction that has been considered as a threat affecting bat conservation. The aim of this study was to collect new data on the diurnal artificial-roost use by bats in a landscape from the southern Amazon. We observed bat species roosting at an abandoned house in a highly fragmented ecotone between the Amazon and Cerrado biomes. We observed one Trachops cirrhosus individual roosting in physical contact with one Phyllostomus hastatus. One year later, we noticed a compositional change at this roost, in which we found a large colony of Pteronotus parnellii. These findings may shed light on the potential flexibility of the roosting requirements of these species in such landscapes. Moreover, this is one of the first records of the use of human constructions by P. parnelli in such fragmented landscapes, a bat species that until recently was thought of as being associated only with well-preserved natural roosts. |
