In this study, we described TL dynamics in wild spur-thighed tortoises (Testudo graeca), one of the chelonian species with the lowest aging rates. By combining cross-sectional (single) and longitudinal (capture–recapture) samplings, we assessed the relationship between TL and individual characteristics (sex, age, individual growth rate, body condition index, presence of shell anomalies).  Leer más.


Co-occurrence between species may be mediated by ecological differences or competitive interactions, but the nature of these interactions can vary across spatial scales. At coarse scales, species may appear to broadly co-occur, but at fine scales, particularly for species with small home ranges, species may utilize different aspects of the microhabitat such that co-occurrence is limited and competitive interactions are reduced or eliminated.  Leer más.
