Comparison of exploratory behavior of three subterranean rodent species
 PLÁNKA, Lukáš
The ability to explore is essential for subterranean mammals, especially due to very high energetic cost of digging. The goal of this study was to examine whether three strictly subterranean rodents with different social system have different pattern of building spatial representation and behaviors in a novel environment represented by open field test. Results showed that the process of building spatial representation in solitary Heliophobius argenteocinereus seems to be similar to the pattern of solitary spalacid, the blind mole rat, from other studies, whereas it clearly differs from both social species. Heliophobius argenteocinereus travelled longer distance than Fukomys mechowii and Fukomys darlingi. Comparison of time spent in different zones of the arena showed more cautious behavior of solitary species as they spent less time in the centre in comparison with both social species. Also the behavioral parameters during the 30 minutes trial showed differences. Parameters connected with loss of interest in pure locomotion like pause and grooming. were more prevalent in social species. No significant sex difference was found, this result is not surprising when compared to other studies.

Mate choice in Sinai spiny mouse \kur{Acomys dimidiatus}.
 PLÁNKA, Lukáš
Mate choice in males and females Sinai Spiny Mouse was examined in T-maze. Males in fidelity test preferred contact/odor of unfamiliar female however females in same test preferred their partners. It seems that males tend to polygyny and females tend to monogamy. The Result of the second test implies that sexually experience is needed for clear preference between mated or unmated partner. Sexually naive females and males did not show clear preference.
