Abstract

The study summarises results of the ichthyologic research of the Podolský and Stříbrný brooks in Hrubý Jeseník. The research was organised for the purpose of finding the actual situation in the fish settlements in the sections of interest and to make suggestions for their further management benefiting the original fish communities.

The results have shown that there is the community of water organisms with naturally reproducing Cottus poecilopus and Salmo trutta in both partly adjusted water flows which have not been restocked by man since 1996.

The facts found within the research suggest that the biologically correct way for the further development of fish populations in the Podolský and Stříbrný brooks may be the maintenance of the existing natural conditions while no local adjustments of the flow beds along roads should be excluded.

The research results have proved that the existing natural conditions and the very limited anthropogenic pressure put on the water biocenoses have been the decisive factors during the formation of the now existing fish population structures which can be assessed as good from the ecological point of view. Because of that we have recommended to the manager of the water flows neither interfering in the development of the current fish populations nor restocking any fishes.

We consider the finding that the age structure and the high numbers of Salmo trutta and Cottus poecilopus have been, in the given situations, the indicators of their populations’ ability, even at the sympatric presence of Lutra lutra and Ciconia nigra, resistant against the predators’ pressure, as very important.

Abstract

Field revision of current distribution of mountain hawkweeds (Hieracium s. str.) in the Hrubý Jeseník Mts was undertaken. Hieracium atratum, H. chlorocephalum, H. engleri, H. grabowskianum and H. plumbeum, whose last occurrence was documented many decades or even a century ago, were rediscovered. H. plumbeum was even found in new localities. The occurrence of H. alpinum, H. bifidum, H. chrysostyloides, H. inuloides, H. nigritum, H. prenanthoides, H. silesiacum, H. stygium and H. villosum was ascertained at many of their historical localities and a few new localities were found too. A neophyte species H. mixtum was discovered. Hieracium moravicum was not found. Accurate locality description and population size are provided for each finding. Herbarium revision and excerption of crucial literature were performed to provide historical distribution. Distributional changes as well as threatening and beneficial factors influencing Hieracium species in the Hrubý Jeseník Mts are discussed.

Abstract

This paper is focused on the fauna of beetles from the Borek u Domašova Nature Reserve (NR) in the Hrubý Jeseník Mountains. Altogether 257 species of beetles belonging to 45 families were recorded during an entomological survey in 2011 and 2012. We found out valuable assemblages of beetles, especially a community of saproxylic beetles which is of high bioindicative value. Recorded were boreo-montane or relict species of natural old-growth forests such as Ceruchus chrysomelinus, Curimus erichsoni, Danosoma fasciata, Dendrophagus crenatus, Elateroides flabellicornis, Hylis foveicollis, Melandrya barbata etc. We propose the following management measures, necessary for the preservation of populations of the threatened species of the Borek u Domašova NR. A non-action strategy seems to be the most appropriate management by means of avoiding the removal of fallen and dead trees from the forest. On the contrary, the structure of the forest should be enriched with fir seedlings, planted and protected from the damage caused by deer. We also recommend to enlarging the area of the NR in the near future.
