Giulliana Appel, a masters student on INPA's Graduate Program in Ecology, jointly with researchers from PPBio / CENBAM, evaluated the influence of lunar luminosity on the flying activity of insectivorous bats. The research was carried out in the Adolpho Ducke Reserve (Manaus-AM), where ultrasound recorders were installed to identify and evaluate the activity of the bats by the ultrasound that they emit.
