Stanovištní charakteristika nosatcovitých v bukových a smrkových ekosystémech Moravskoslezských Beskyd
Hrabovský, Karel
Title of the diploma´s thesis: Habitat characteristics weevils in beech and spruce forest ecosystems Moravian-Silesian Beskydy In forest ecosystems Moravskoslezské Beskydy was conducted from 2007 to 2015 collection epigeic fauna using ground traps. Trapping took place at 6-week inter-vals from May to October. Family (Curculionidae) was evaluated in beech spruce stands using faunistic index in relation to the basic typological units which are forest vegetation zones (LVS), edaphic category (EK), forest type (SLT) and ecotope conditions such as soil type, soil chemistry, humus form and composition of the herb layer. Incidence was compared of Curculionidae in selected nature reserves in silviculture stands. Total were captured 26,743 individuals of Curculionidae amount of 52 species. Eudominant species are Otiorhynchus carinatopunctatus, Plinthus tischeri, Otiorhynchus tenebricosus, Rhinomias forticornis and Strophosoma melanogrammum. In Beskydy they were captured rare species Barynotus moerens and Barypeithes mollicomus. It was found continuity of some species of Curculionidae on forest vegetation zones (LVS), edaphic categories (EK) and continuity some species of Curcilionidae on soil attribute.

Vliv stanovištních podmínek na faunu střevlíkovitých ve smrkových a bukových porostech Beskyd
Rolinc, Petr
In beech and spruce stands in the LS Ostravice in Moravia Silesian Beskydy was realized monitoring of epigeic invertebrates by pitfall traps method. Carabid beetles (Carabidae) were classified as bioindicator group in terms of representation in spruce and beech stands with regard to main typopologic kategories like as forest altitudinal vegetation groups (LVS), edaphic categories (EK) and files of forest types (SLT). Ground beetles communities were evaluated in economic forests and nature reserves. Collecting of ground beetles was realized in period 2007 -- 2014 in the spring, summer, late summer and autumn aspect. In the entire period were captured 67 483 individuals of ground beetles belonged to 77 species. In interest area was confirmed the occurrence of legally protected species and species Natura 2000 (Carabus variolosus Sturm). Another protected and heavilly endagered species was Carabus obsoletus Sturm. Carabus linnei, Pterostichus burmeisteri and Pterostichus foveolatus were eudominant species. The dominant species were represented Abax ovalis, Carabus glabratus and Pterostichus oblongopunctatus. There was proved a relation between carabid beetles and main typologic categories (LVS, EK and SLT). Several species were discovered diference between spruce and beech stands and so between nature reserves and economic forests.

Ichtyofauna of selected streams of Bohemian Forest
ŠRÁMEK, Jiří
Presented work is directed to summarize the results of ochtyomonitoring of five stream in Bohemian Forest in autumn 2010. The processing status is evaluated fish communities, especially their species composition, diversity, dominance, evenness and other parameters. They have been evaluated also physico-chemical properties of the sites such as air and water temperature, conductivity and turbidity. Last but not least were evaluated the characteristics of flows and in particular morphological characteristics, types of the bottom substrate and its contours etc. The evaluation of all obtained data showed that fish communities surveyed Bohemian flows are balanced, they are not burdened with invasive species and rand indicators correlated with the state of flow, geographic location and natural conditions. It was caught nine fish species in the total number of 963 individuals. Abundance was at all locations in the range 201,6 to 409,7 individuals per kilometer of flow, showed the diversity of communities from 0,372093 to 2,166085 (Shannon and Wiener index) and from 0,301804 to 0,866948 (Simpson index), then evenness of plant 0,372093 to 0,783906. The most dominant species was the brown trout, the second most frequent species was bullhead.

The age sructure of the roach (Rutilus rutilus) population and the chevin (Leuciscus cephalus) population in the Blanice river
BLÁHA, Josef
The Blanice river has its spring in the Šumava Protected Landscape Reserve near Zlatá at an altitude of 972 m a.s.l. and empties in the Otava river near Putim at an altitude of 362 a.s.l. The size of its catchment area is 860,5 km2, the watercourse is 93,3 km and the flow rate at the confluence is 4,23 m3.s-1. The upper reaches of the Blanice has a typical submontane, trout character, which is disturbed by the Husinec reservoir (the water area is 68 ha, maximal depth 25,5 m). The lower two thirds of the river run through an array of ponds in the region of Vodňany and Protivín. This area is intensively cultivated by agricultural activities. These two factors play the major role the fact that the lower part of the river is strongly eutrophicated. This is also supported by the abundance survey, according to which the most abundant species are roach (Rutilus rutilus) and chub (Leuciscus cephalus). The survey was made at 9 localities encompassing the main biotope types in the longitudinal profile of the lower part of the Blanice in the region of Vodňany and Protivín. The harvests were carried out within a 50-meter section, always in the upstream direction towards the place that kept the fish from escape (a small weir, a knickpoint). The most abundant species {--} Rutilus rutilus and Leuciscus cephalus {--} were evaluated from the viewpoint of the age distribution of the population.
