Animals can use two variants of the magnetic compass: the 'polar compass' or the 'inclination compass'. Among vertebrates, the compass type has been identified for salmon, mole rats, birds, turtles and urodeles. However, no experiments have been conducted to determine the compass variant in anurans.

To date, it is unknown whether young-of-the-year anurans perform a random or directional search for the hibernation sites, and what cues (global or local) they use. We conducted a series of field experiments to study the orientation behavior of juvenile common frogs during their first wintering migration.

- Valentin's rock lizard is believed to be the parent species of several parthenogenetic rock lizard species, indicating complex evolutionary processes in their shared habitats.
- This lizard species is long-lived and exhibits a distinctive size difference between genders, with females being larger, which is atypical for its genus.
- They have adaptations for high-altitude living, such as larger eggs and early reproduction, and their population density can vary widely without being impacted by the presence of parthenogenic species.
