The impact of ungulates on epigeic assemblages of centipedes (Chilopoda) in the Křivoklátsko Protected Landscape Area - preliminary results
Aurová, Klára
2009 - English
The Křivoklátsko Protected Landscape Area and Biosphere Reserve (Czech Republic) represents a unique region covered in a high portion by forest ecosystems. Densities of ungulates in the forests are unusually high. Their impact on ecosystem is important, especially due to the removal and consumption of herbage, trampling of soil and vegetation, and the return of excreta. The aim of field study was to elucidate the impact of ungulates on soil invertebrates represented by centipedes. In this paper the first data about possible impact of ungulates on epigeic assemblage of centipedes are presented. In total, 9 centipede species were recorded. The species .i.Lithobius mutabilis./i. was dominant during the whole observation in all monitored plots. At the beginning of the experiment in 1994, this centipede outweighed other species with 91 %. After 12 years in 2006 the amount of other species arose almost up to 1/4 outside and more than 1/3 inside the fenced plots.

Rusek, Josef; Reithofer, D.; Schmid, S.; Truxa, Ch.; Weber, J.; Wilde, U.
2009 - English
Communities of soil Collembola, Protura and Pauropoda were studied in a riparian forest - mesic forest ecotone in the Stromovka Park in the inundation zone of the Vltava River in České Budějovice, South Bohemia, Czech Republic. Ten soil samples, each 10 cm.sup.2./sup. and 5 cm deep, were taken on April 3rd, 2000 in each of five parallel rows from the swampy part without water (row I). Row II was 1 m to the east from row I in a dense .i.Pragmites communis./i. uderstory of the .i.Populus canadensis, Quercus robus./i. dominated riparian forest. Row III was 5 m to the east with the same understory composition, and IV was 10 m further to the east with less dense .i.Phragmites./i. understory growth mixed with grasses and .i.Geranium silvaticum./i. and other understory herbs and poplar and oak litter on the soil surface. Row V was 5 m from row IV in a mesic forest with .i.Quercus robur, Betula alba./i. trees and grass with mosses in understory.

Changes in centipede assemblages (Chilopoda) along the vertical and vegetation gradient in the Bieszczady Mountains, Poland
Wytwer, J.; Tajovský, Karel
2009 - English
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.

Has .i.Tilia x euchlora./i. a detrimental effect on soil annelids in urban greens?
Schlaghamerský, J.; Khodabocus, J.B.; Pižl, Václav
2009 - English
The potential effect of the exotic linden .i.Tilia x euchlora./i., widely planted in urban greens, on soil-dwelling annelids (Lumbricidae, Enchytraeidae) was investigated in two parks in the city of Brno, Czech Republic. Linden trees are the source of honeydew that might affect soil biota and remains an important input of these trees into the soil compartment even if litter is being removed as part of the park management. There have also been discussions about the alleged toxicity of .i.T. x euchlora./i. nectar to pollinators. The native .i.T. platyphyllos./i. was used as a control. Within two days in November 2006 annelids were sampled at three different distances (1 m, 3 m, 6 m) along transects from the trees to well developed lawns. Earthworms were extracted by the electrical-octet method, enchytraeids by wet funnel extraction from soil cores taken down to 12 cm.

Species and genera of soil nematodes inhabiting tree plantations on colliery spoils near Sokolov
Háněl, Ladislav
2009 - English
Soil nematodes were studied in 20-30-year-old tree plantations and spontaneous successions on colliery spoils near Sokolov in west Bohemia, Czech Republic. Six types of tree plantations (oak, alder, linden, larch, pine, and spruce) and one type of spontaneous succession (willow-aspen-birch), each in four replicate sites, were surveyed in March 2005 and in April 2006. In total 174 species and 86 genera were distinguished, more species and genera were found in deciduous than in coniferous plantations. Cluster analyses showed different composition of nematode faunas in those plantations. Co-occurrence of closely related .i.Aporcelaimellus, Helicotylenchus./i. species could suggest their still existing niche overlap in a developing environment whereas niche partitioning probably established between species of the genera .i.Eudorylaimus./i. and .i.Paratylenchus./i..

Good parasitic wasps gone bad: a short review of two stories of the oceanic and habitat islands
Lozan, Aurel; Spitzer, Karel; Jaroš, Josef
2009 - English
Braconid parasitoid Cotesia glomerata, which was accidentally introduced into Canary Islands became real threat to the Canary Island Large White butterfly (Pieris cheiranthi). The multiple confirmation of the origin of the introduced parasitoid (morphology, DNA, ecology) suggests that these opportunistic parasitoids might be a serious danger to native isolated fauna. Such model relationships can be found in isolated paleorefugial habitats of the central European peat bogs, which are historical habitat islands of unique local taxa. A recent discovery of some opportunistic parasitoids attacking tyrphobiontic Lepidoptera in several isolated bogs of South Bohemia suggest these wasps might invade isolated habitats and cause serious population destruction of paleorefugial hosts.

Digestive enzymes in ants (Hymenoptera: Formicidae) : a short review
Šustr, Vladimír; Schlick-Steiner, B.C.; Steiner, F. M.
2009 - English
The literature data on the digestive enzymes present in different taxonomic groups of ants are reviewed and their patterns of occurrence across the various groups are tested. Data are available on 32 digestive enzymes from 62 ant species from 15 tribes belonging to seven subfamilies (Dolichoderinae, Ecitoninae, Formicinae, Myrmicinae, Paraponerinae, Ponerinae, and Pseudomyrmecinae). Leaf-cutter ants (Myrmicinae, higher Attini) are the best-investigated group. Nearly all analysed enzymes were present in all the species investigated, irrespective of taxonomic group. The only significant difference across taxonomic groups concerns enzymes that attack plant structural polysaccharides (cellulases, pectinase, xylanase). These were more frequent in leaf-cutter ants than in other groups. To detect potential additional differences between groups differing in their feeding habits, more comprehensive qualitative data acquisition will be necessary.

Vertical Collembola distribution in spruce and beech forest soils
Jínová, Kristýna
2009 - English
Vertical stratification of Collembola was investigated in beech and spruce forest soils on the Kleť Mountain (Blanský les Protected Landscape Area, South Bohemia, Czech Republic). The aim of the study was to describe the collembolan distribution among the horizons in the present beech and spruce forest soils and to find out which species were dominant in the individual soil layers. Ten soil samples (each of 10 cm.sup.2./sup., 15 cm deep) were collected in beech and spruce forest on the Kleť Mt. in December 2004. They were divided into 5 sub-samples: litter + 0-1 cm of soil; 1-2, 2-5, 5-10, and 10-15 cm and extracted separately in high-gradient Tullgren apparatus. In total, 40 species were found at both sites (31 in the beech and 28 in the spruce forest). The highest number of species was found in the upper layer (litter layer + 0-1 cm) of soil, 84 % of species in the beech forest and 64 % in the spruce forest.
