The aim of this thesis is the evaluation of species diversity of the spider family Ly-cosidae in three locations near Znojmo: Nature Park Ječmeniště, Peklo u Šatova and Hnanice. In all the locations the specimens were collected on agricultural terraces used for cultivation of grapevine. The spiders were collected by the means of pitfall trapping. The traps were set on 8th May 2014 and collected on 5th June 2014, 3rd July 2014, 1st August 2014, 27th Sep-tember 2014 and 25th October 2014. Together there were 223 of Lycosidae spiders caught. 99 of them were juveniles and the remaining 223 were adults that were eventu-ally determined. Together there were detected 16 species belonging to 5 genera (Alope-cosa, Aulonia, Pardosa, Trochosa and Xerolycosa). The most significant finding is the finding of Pardosa bifasciata species, which is abundant only in warm areas. Although this species was collected in Peklo u Šatova and in Hnanice, it was not detected in NP Ječmeniště. None of the species collected in the three locations is listed in the Red List of Threatened Species of the Czech Republic.

The aim of this work was to find a horizontal influence on the composition of the fauna of wolf spiders located on the banks of the river Morávka (Moravian-Silesian Region). The collection takes place in five selected areas to cover the entire length of the river. It was the region og the spring, the Morávka, Pražmo, Skalice and Frýdek-Místek districts. Spiders were hunted using earth traps. The selection of traps took place on 10 June 2017, 8 July 2017 and 6 August 2017. An important discovery is the finding of one very rare species - Pardosa agricola, two rare species - Arctosa maculata and Pardosa morosa.

Members of a guild of cursorial spiders (Pardosa spp. and Alopecosa spp.) spatially segregated among five discrete habitats, from a streamside cobble habitat grading laterally along a successional gradient to the leaf litter zone of a transition or climax riparian forest. Seasonal activity peaked in midsummer for all guild members. Spiders were active diurnally earlier in the streamside habitats, and levels of activity were positively correlated with light intensity. Guild members Pardosa tristis and Pardosa uncata were most different in habitat selection and periods of diurnal activity. Males and females of all guild species differed in their distribution among habitats and over months of collection. Measures of guild species diversity and evenness were variable between habitats, and were largely influenced by the relatively high abundance of one or two guild species, particularly in the streamside habitats.
