Abstract
The reliability of the post hoc measurement, a non-invasive method for measuring wild animals, was tested on Salamandra salamandra. Our results show that SVL measured in the field was lower than SVL estimated from images by three operators and that the estimates were highly consistent. In addition to the potential greater accuracy of this method in estimating SVL compared to the measurements obtained in the field, it allows to significantly reduce the handling times of the animals, thus reducing the stress caused to the salamanders.
