A comparison between phalangeal skeletochronology and cephalic parietal rings in lizards

As expected, body size increased nonlinearly with both age estimate methods. However, Spearman’s correlation and model 2 linear regression suggest limited precision and bias when transposing results between different methods. Overall, the cephalic rings method faced practical challenges for lacertid species in the genus Podarcis. Leer.más.

Understanding benefits and risks of exploiting spring habitats by subterranean animals: insights from a mark-recapture study on the olm (Proteus anguinus)

The results confirm the ecological importance of these karstic springs habitats, which support high biodiversity, species interactions, and serve as key points for studying the adaptive responses of Proteus anguinus and other subterranean species. Leer más.
