Abstract

Contribution to the study of Bats (Mammalia, Chiroptera) in the region of Bordj Bou Arréridj Here we present preliminary data on the diversity of chiroptera in the BBA regency. The results obtained by ultrasonic detection in 3sites highlight the existence of 5 species of 4 genera belonging to 2 families; Khul's Pipistrelle (Pipistrellus kuhlii, Kuhl 1817), Pipistrelle pipustrelle (Pipustrellus pipistrellus, Schreber 1774), Isabelle serotine (Eptesicus isabellinus, Temminck 1839), Savi's Vespers (Hypsugo savii Bonaparte, 1837), Schreibers' Minioptere (Miniopterus schreibersii, Kuhl 1817). Among the species contacted during this study, we report that the Khul Pipistrelle is the most abundant and that at the rate of 71,27% (196 contacts), thereafter it is the Vespers of Savi noted by a rate of 09.09% (25 contacts). The less abundant species is Eptesicus isabellinus with a rate of 04.36% (12 contacts). Keywords : Bats, biodiversity, BBA, Echolocation ان
