The Rufous Sengi is not Elephantulus Multilocus reconstruction of evolutionary history of sengis from the subfamily Macroscelidinae
 KRÁSOVÁ, Jarmila
We conducted multilocus phylogeny and divergence dating of sengis also known as elephant shrews from the subfamily Macroscelidinae. For the first time, we provided genetic evidence that the East African Rufous Sengi (Elephantulus rufescens) is closely related to the recently delimited genus Galegeeska known from the Horn of Africa and comprising a single species G. revolii. Our findings are in concordance with morphological traits and also biogeographical patterns known from Eastern Africa. Based on the results of divergence dating, the genus Galegeeska originated in the Pleistocene era.

Phylogeny of Grey-bellied Pygmy Mouse (\kur{Mus triton}) complex
 KRÁSOVÁ, Jarmila
The Grey-bellied Pygmy Mouse (Mus triton) has been for a long time considered as a single species, although validity of the single species status was questioned. In order to revise current taxonomy of M. triton, I analyzed sequences of one mitochondrial (cytochrome b) and two nuclear genes (IRBP and Intron 7 of the fibrinogen) from specimens collected across the most of its known distributional range. Four well-supported phylogroups at species level, differentiated during the Plio-Pleistocene, were evidenced. Divergence dating suggests that the diversification of "triton" species complex was likely caused by Plio-Pleistocene climatic oscillations together with highly diverse topography of Eastern Africa
