The mineralogy is described only briefly according to the main purpose, which was detailed mapping of the mining works. Relics of historical mining works were mapped on a scale of 1:3000 and in total 1259 workings were found. Previous papers and mapping results were correlated and greatly improved knowledge about historical gold mining in the Humpolec area. Many new huge placer mines and mining relics were found in the Trucbába-Valcha area, and many unknown small workings were also revealed in the Na Štůlách area. Historical mining in the Humpolec area was probably on a much larger scale than previously expected. Key words: Humpolec, historical, mining, workings, medieval, gold, deposit, sink hole, placer

2 Šipákové doubravy na Vysočině Vegetation of Downy Oak Forests in the Vysočina Region (Moravia, Czech Republic) JAN ROLEČEK Ústav botaniky a zoologie, Masarykova univerzita, Kotlářská 2, Brno, CZ ; Botanický ústav AV ČR, Oddělení vegetační ekologie, Lidická 25/27, Brno, CZ ; honza.rolecek@centrum.cz Abstract: Downy oak forests are communities of thermophilous oak forests occurring on base-rich soils in warm and dry lowlands and hilly regions of Central Europe. In southern Moravia, they occur mainly on the southern outposts of the Western Carpathians. However, a recent survey revealed several new sites on the south-eastern edge of the Bohemian Massif. The present study documents vegetation at three peripheral sites of downy oak forests located deep in the Bohemian Massif, on the boundary of the Vysočina region. All three sites are confined to spots of base-rich soils in predominantly acidic environments of the Rokytná, Jihlava and Chvojnice river valleys. Downy oak forest vegetation is well developed here and includes many thermophilous species, some of which reach their distributional limit in Moravia here. Classification based on cluster analysis assigned most recorded relevés to a Quercion pubescenti-petraeae alliance. The study acknowledges the importance of thermophilous communities for the biodiversity of the Vysočina region.

3 Faunistický průzkum můrovitých (Lepidoptera: Noctuidae) na lokalitě Stupník v Chráněné krajinné oblasti Žďárské vrchy Faunistic Survey of the Noctuid Moths (Lepidoptera: Noctuidae) at the Stupník Site in Žďárské vrchy Protected Landscape Area PAVEL BÍNA Kocanda 328, Herálec, CZ; pavelbina@gmail.com Abstract: The findings of a two-year faunistic study on the noctuid moths (Noctuidae) conducted at the Stupník site in Žďárské vrchy hills in the Bohemian-Moravian Highland are summarized. The number of species and individuals were monitored using a light trap; 144 species were found among 7,889 individuals. The interesting species are commented on from the faunistic and ecological point of view. Key words: noctuid moths, faunistic, Žďárské vrchy hills, Bohemian-Moravian Highland, Czech Republic

4 Motýli (Lepidoptera) údolí řeky Brtnice II Butterflies and Moths (Lepidoptera) of Brtnice Valley II JAN ŠUMPICH Česká Bělá 212, CZ Česká Bělá; Abstract: This contribution summarizes all present knowledge about lepidopteran fauna in Brtnice Valley (declared as Údolí Brtnice Nature Reserve) acquired from various sources, in particular from research executed between 1993 and 1997 (Šumpich et Dvořák 1998) and The result is a summary of 968 butterfly and moth species found. As it turns out, there is a high probability that some ecologically demanding species died out in that location, namely Iphiclides podalirius (Linnaeus, 1758), Pseudophilotes vicrama (Moore, 1865), Glaucopsyche alexis (Poda, 1761), Maculinea arion (Linnaeus, 1758), Polyommatus dorylas (Den. et Schiff., 1775) and Coenonympha tullia (Müller, 1764); on the other hand, for some spreading species Brtnice Valley provides a suitable habitat, e.g. Colias erate (Esper, 1805), Lycaena dispar (Haworth, 1803), Proxenus lepigone (Möschler, 1860), Apamea oblonga (Haworth, 1809), Mythimna sicula (Treitschke, 1835) or Noctua interjecta Hübner, Siederia pineti (Zeller, 1852) and Platyptilia farfarella (Zeller, 1867) were recorded in Moravia for the first time; Syncopacma azosterella (Her.-Sch., 1854) is new for the Czech Republic. Brtnice Valley is currently probably the most north-western locality in Moravia for the following species: Batia internella (Jäckh, 1972), Coleophora oriolella (Zeller, 1849), Rhyacionia hafneri (Rebel, 1937), Stenoptilia annadactyla (Sutter, 1988), Agriphila tolli (Bleszyňski, 1952), Brintesia circe (Fabricius, 1775) and Arethusana arethusa (Den. et Schiff., 1775). Changes in lepidopteran taxocoenoses in dependence on spontaneous succession of natural habitats in the past few decades are discussed.

5 Přirozená radioaktivita čerstvých a hydrotermálně alterovaných hornin na lokalitě Pohled (moldanubikum) Natural Radioactivity of Fresh and Hydrothermally Altered Rocks at the Pohled locality (Moldanubicum) EVA MASTÍKOVÁ, ZDENĚK DOLNÍČEK Katedra geologie, Palackého univerzita, 17. listopadu 12, Olomouc, CZ ; evamastikova@centrum.cz; dolnicek@prfnw.upol.cz Abstract: In quarry Pohled near Havlíčkův Brod there are found mainly Moldanubian granites and paragneisses, rarely also amphibolite, eclogite, serpentinite and pyroxenite. The rocks are cut by numerous hydrothermal veins and in their neighbourhood there are developed extensive hydrothermal alterations. In addition, disseminated Mo-mineralization occurs in granites. Both macroscopic and microscopic changes are observed especially in granites and gneisses adjacent to mineralization. Radioactivity of fresh and altered rocks was measured using field and laboratory gamma-ray spectrometry. The highest measured values of K, U and Th showed granites. Altered granite showed higher average content of K (3.5%) and lower Th (11.9 ppm) than fresh unaltered granite (K 3.0 %, Th 13.3 ppm), whereas content of U is essentially the same, 6.0 ppm. Gneisses have average content of potassium 1.3 %, thorium 2.8 ppm and uranium 2.2 ppm. During alteration, increase of content of K, U and Th was observed. Pegmatite veins had average content of potassium 2.7 %, uranium 6.9 ppm and thorium below detection limit (<1.5 ppm). Amphibolites, eclogites, serpentinites and pyroxenites have the all determined elements below detection limits. Generally the rocks investigated belong to low or middle radioactive one.

7 Řasová flóra Fryšávky v CHKO Žďárské vrchy Algae of the Fryšávka Stream in the protected region Žďárské vrchy BLAŽENA BRABCOVÁ 1, JAROSLAVA BUCHTOVÁ 2 1Katedra biologie, Pedagogická fakulta, Masarykova univerzita, Poříčí 7/11, CZ Brno; brabcova@ped.muni.cz; 2 Daňkovice 81, CZ Sněžné Abstract: The paper deals with the distribution of cyanobacteria and algae taxa at 13 sites distributed in a longitudinal profile of the Fryšávka Stream in the Bohemian-Moravian Highlands, in the protected area of Žďárské vrchy. The work contains results on the quality of community cyanobacteria and algae, the relative abundance of diatoms and some abiotic parameters of the water. Fieldwork research was carried out during the 2005 vegetation season. Samples were taken six times during that season. Altogether, 211 taxa cyanobacteria and algae were recorded. The most abundant were taxa of diatoms. The distributional patterns of abundant and indicative taxa are discussed with respect ecological links to environmental parameters.

Several types of wet meadows, characteristic for higher altitudes of Bohemian-Moravian Highlands, occur on these relatively small sites. During a floristic research conducted in 2010, 153 taxa of vascular plants (six of them included in the Czech red list) have been recorded at U Bezděkova site; 144 taxa (twelve of them included in the Czech red list) have been recorded at Díly u Lhotky site; in both cases these numbers are higher than those recorded during the last researches performed in 80 s of the 20th century. Identified vegetation types are documented by five and seven phytosociological relevés, respectively. The types were assigned to following syntaxa using an expert system: Poo- Trisetetum fl avescentis (Arrhenatherion), Angelico-Cirsietum palustris (Calthion), Cirsietum rivularis (Calthion), Lysimachio vulgaris-filipenduletum (Calthion), Festuco capillatae-nardetum (Violion caninae), Equiseto fl uviatilis-caricetum rostratae (Magno-Caricion elatae) and Sphagno recurvi- Caricetum rostratae (Sphagno-Caricion canescentis).
