Long-term impact of forestry management on soil mesofauna (Oribatida, Collembola) biodiversity in spruce forests in the Šumava National Park
 Farská, Jitka ; Jínová, Kristýna
The aim of our research is to compare Oribatid and Collembolan communities in climax spruce forest and spruce plantations. Soil samples were collected in five study sites in the Šumava National Park (5 in climax spruce forest and 5 in spruce plantation) and soil microarthropods were extracted. Oribatida and Collembola were determined to species level. Preliminary results show quantitative and qualitative changes in the community structure. Some euedaphic species do not occur in the samples from spruce plantations in comparison to the climax forests. Silvicultural practices are well known to affect microarthropod communities that are very sensitive to fluctuations in soil humidity and temperature.

Impact of intensive trampling on soil animals in the Boubín National Natural Reserve, Czech Republic
 Rusek, Josef
The impact of intensive tourist activity (trampling) on the soil fauna diversity in the Boubín National Natural Reserve (Czech Republic) was investigated. Quantitative soil samples were collected in the climax spruce forest 200 m north of the scenic observatory on the top of the Boubín Mt. (Loc. No. 1), than on a highly frequented (Loc. No. 2) and less frequented walkways (Loc. No. 3), and on a 1,5 year no more used one (Loc. No. 4). Collembola, Protura, Diplura, and Symphyla species were used as bioindicators of the trampling impact. Highest density and species number of the mentioned soil animal groups was established on the Loc. No. 1 (353100 specimens.m.sup.-2./sup. and 34 species of Collembola, 5300 specimens.m.sup.-2./sup. and 1 species of Protura, 200 specimens.m.sup.-2./sup. and 1 species of Diplura, 5600 specimens.m.sup.-2./sup. and 2 species of Symphyla).
