Communities of millipedes (.i.Diplopoda./i.) and centipedes (.i.Chilopoda./i.) in changing conditions of montane spruce forests of the Šumava Mountains
Tajovský, Karel
In the nineties of the past century, large climax Norway spruce (.i.Picea abies./i.) areas of the Šumava Mountains were damaged by the bark beetle outbreak. The subsequent decay of spruce growths become the object of interest for management practice, nature protection as well as research activities. While the changes in forest growths under the bark beetle outbreak were well visible, there were no information about the impact of these processes and subsequent management practices used (clear cutting, spontaneous development of dead growths) on soil environments and existing communities of soil organisms. Within the soil zoological research in 1999-2010 near the localities Březník and Studená hora Mt., qualitative and quantitative parameters of millipede and centipede assemblages were studied in undamaged, damaged and dead forest stands, and in differently old clearings. Combination of methods of pitfall trapping and soil sampling served data about the composition and changes of communities of both invertebrate groups.

Findings of new troglophilous millipede species
Tajovský, Karel ; Mlejnek, R.
The recent research carried out by the Cave Administration of the Czech Republic in co-operation with the Institute of Soil Biology, Academy of Science of the Czech Republic, České Budějovice clearly shows that invertebrate species diversity in caves in the Czech Republic is much higher than it was previously thought. In 32 caves in Bohemia and Moravia, 35 millipede species have been found which is about a half of the number inhabiting the Czech Republic as a whole. In species -poor and simplified food webs in caves and other underground habitats, millipedes play a significant role in litter decomposition and in control and spreading micro-organisms, particularly microscopic fungi. Therefore, keeping the decayed (rotted) wood can maintain necessary life conditions for these invertebrates there. Two millipede species are new for the Czech Republic fauna. The tiny white millipede .i.Brachychaeteuma bradeae./i. has been reported from six caves while .i.Macrosternodesmus palicola./i. occurs on the country's territory only at the Mladeč Caves (central Moravia).

Invertebrate fauna in Zbrašov aragonite caves
Tajovský, Karel ; Tuf, I.H. ; Papáč, V. ; Růžička, Vlastimil ; Mlejnek, R.
This contribution summarized the research of invertebrate fauna in ZAC. They have been implemented since the nineties of the 20th century. The most intensive study has started since 2001, when the Cave Administration of the Czech Republic in cooperation with existing workplaces of Biology Centre AS CR in České Budějovice and the Palacký University in Olomouc systematically explored the entire cave. The result was the detection of 49 kinds of invertebrates. The observed fauna consists of troglofilous species whose population evidently lives permanently here, and also number of representatives who occasionally penetrate the caves from the outside or have found the better conditions in the cooler parts of the year here. The contribution commented on some more important species.

Changes in centipede assemblages (Chilopoda) along the vertical and vegetation gradient in the Bieszczady Mountains, Poland
Wytwer, J. ; Tajovský, Karel
Changes in community parameters of the centipede assemblages in habitats with different vegetation along the vertical gradient were studied in the Bieszczady National Park, Poland. Ten stands, from riparian alder forest through eutrophic beech forests to open habitats in subalpine grasslands, within the altitude range 612–1,218 m a.s.l. were sampled. Pitfall trapping and soil sampling were used for the collection of animals since June 2005 till June 2006. In total, 848 specimens of centipedes belonging to 19 species were sampled. Among them, the species .i.Lithobius latro./i. was recorded in Poland for the first time. .i.Lithobius lucifugus, Strigamia transsilvanica, Geophilus insculptus, Schendyla carniolensis./i. were found in this region of Poland for the first time. Specimens of the genus .i.Stenotaenia./i. recorded in the study sites represent a new stenotopic species. Between 7 and 14 species were found in each stand.
