Estacionalidad reproductiva en el vampiro común Desmodus rotundus (Cbiroptera, Phyllostomidae) en el Valle de Lerma (Salta, Argentina)

The chiropteran reproductive parterns in tropical zones have been associated with food seasonality by synchronization between parturition time and the lrighest environmental productivity. In lhe common vampire ba, (Desmodus rotundus) whose food (catde blood), is widely available year round, reproduc...
