Comparison of age determination methods for Desmodus rotundus Chiroptera Phyllostomidae Comparacion de metodos para la determinacion de edad en el vampiro comun Desmodus rotundus Chiroptera Phyllostomidae
Age estimation methods in the common vampire bat (Desmodus rotundus) were compared on 81 individuals from a natural cave in Ampascachi, Salta province (Argentina). Age was assessed by counting incisor growth lines in the root cementum. This estimation was compared with forearm and tibia length and dentine-cementum and percentage of dentine attrition indices. Age estimation by both forearm and tibia length were less reliable (Pearson r = 0.29 and 0.33 respectively) than dentine attrition and dentine-cementum indices (r = -0.90 and 0.88 respectively). McNemar and Cohen-Kappa tests showed that dentine attrition index had the best fit with aging by growth lines.
