Porovnání araneofauny dutin ovocných dřevin v okolí liniových staveb v Brně - Obřany a Rohozná
Boučková, Monika
The aim of my bachelor thesis was to determine the number of spiders in the cavities of fruit alley trees around the line structures (path, roads). I chose two localities, one made of fruit and the other leafy trees, which I then compare. I caught the spiders in the news traps during the 2014/2015 period every month. I found a total of 163 spiders, of which only 5 were adult. I found these adults in the summer months in a different kind of representation. The most numerous of them is the family Salticidae represented by 2 pieces. Juvenile individuals were the most represented by the families of Philodromidae. These species I discovered 61 predominantly on Malus domestica. Keywords: spiders, trees, cavities, line structures, adult, juvenile

Toxicity of selected substances for spiny-cheek crayfish
MAHOVSKÁ, Ivana
The thesis examined the toxicity of selected compounds for spiny-cheek crayfish (Orconectes limosus) in laboratory conditions. Tested the acute toxicity of the insecticide Diazinon 60 EC and herbicide Roundup Biaktiv. Tests were chosen to juveniles spiny-cheek crayfish (Orconectes limosus), and juvenile and adult specimens of signal crayfish (Pacifastacus leniusculus).These species of crayfish have been selected as an easily accessible model organism. Both species of crayfish spreading and in Europe they are unoriginal. Work focused on the observed toxicity of these substances on spiny-cheek crayfish and signal crayfish and the demands on the quality of the environment.
