Forest fragmentation and deforestation are among the major threats to Peruvian bats conservation. Unfortunately,information about the effects of these threats above 500 m elevation is lacking. In this study, I assessed
bat responses to fragmentation in Pozuzo (Pasco) at a landscape scale approach. I evaluate two hypotheses
regarding the role of bats as indicators of habitat disturbance. The first prediction says that landscapes highly
disturbed will show higher abundances of habitat generalist species such as frugivorous bats belonging to the
subfamilies Stenodermatinae and Carollinae. The second prediction regards that landscapes with greater forest
cover will show higher abundance of habitat specialist species such as animalivorous bat species belonging
to the subfamily Phyllostominae, a guild sensitive to forest disturbance. I found evidence supporting the animalivorous
hypothesis but it was partial to the frugivorous hypothesis. This study highlights the importance of
forest fragments to bat conservation in human-modified landscapes.
