Behaviour and spatial activity of deer (red deer, roe deer) in the Šumava National Park in relationship to the damage on forest stands
 Šustr, P. ; Jirsa, A. ; Krojerová, Jarmila ; Barančeková, Miroslava
The research of spatial behaviour and activity of red and roe deer has been carried out in the Šumava National park. Preliminary results show that one part of red deer population regularly migrates to higher altitudes during vegetation season, whereas the others stay in lower altitudes. Further, the activity of red deer was the highest during June and October, and the lowest during winter. A part of this study is also the research of feeding ecology of both species. We detected a relatively large proportion of needles in the diet of both species. Also the proportion of deciduous trees was relatively high in some parts of the study area. This indicates a relatively high influence of both species on natural forest regeneration

Genetická struktura populací lína Tinca tinca (Linnaeus, 1758)
 Lajbner, Zdeněk ; Linhart, Otomar ; Kotlík, Petr
The tench is an important fish for aquaculture, which is undergoing intensive domestication, but only few studies have examined genetic structure of its populations. We present first results of a phylogeographic study based on DNA sequence data for four nuclear genes and one mitochondrial DNA gene from throughout the tench geographical distribution, including some of the known transfers outside its native Eurasian range. The multiple gene dataset revealed a strong phylogeographic partitioning between the western and eastern parts of the species range with a wide zone of overlap in Europe. Tench in European aquaculture largely represent mixtures of the two evolutionary lineages. We will discuss the likely historical processes underlying these findings. We suggest that human-mediated dispersal may have played an important role in shaping the present phylogeographic pattern.
