Spiders (Araneae) of Zbrašovské aragonitové jeskyně National Nature Monument (Moravia, Czech Republic)

Spiders of non-cave part of Zbrašovské aragonitové jeskyně National Nature Monument were investigated during the year 2011. Several capture methods were used from April to October. Altogether, 71 species from 20 families were recorded and 46 more species were allready found in previous studies. Until 2012, there are 89 species known from this NNM in total. Several remarkable species were found: Ceratinella major, Megalepthyphantes nebulosus, Porrhomma convexum. Most of spider species from the locality belong to climax (C) and semi-natural (SN) habitat species

Spiders (Araneae) of Hůrka u Hranic National Nature Reserve (Moravia, Czech Republic)

Spiders of Hůrka u Hranic National Nature Reserve were investigated during the year 2011. Several capture methods were used during the vegetation season (from April to November) in many various habitats of this territory. Altogether, 92 species from 27 families were recorded, including very rare and remarcable species. Majority of such species prefer thermophilous habitats: Atypus affinis Eichwald, 1830, Dysdera czechica Řezáč, in prep., Theridion melanurum Hahn, 1831, Agroeca cuprea Menge, 1873, Drassyllus villicus (Thorell, 1875), Zodarion germanicum (C. L. Koch, 1837) and Dipoena melanogaster (C. L. Koch, 1837). Some species are also listed in the Red List of threatened species in the Czech Republic: Cheiracanthium elegans Thorell, 1875 in category endangered (EN), Cozyptila blackwalli (Simon, 1875) and Leptorchestes berolinensis (C. L. Koch, 1846) in category vulnerable (VU). Altogether, 144 spider species are now known from the reserve; they represent 16.6% of araneofauna of the Czech Republic

Spiders of Polanská Niva National Nature Reserve

Spiders of Polanská niva National Nature Reserve were investigated during 2013. Several capture methods were used from March to September. Altogether, 85 species from 14 families were recorded. The most interesting species are Arctosa maculata (Hahn, 1822) and Micaria nivosa L. Koch, 1866 (both are vunerable according to the Red List of threatened species in the Czech Republic). The other remarkable species were: Kaestneria pullata (O. P.- Cambridge, 1863), Donacochara speciosa (Thorell, 1875), Hylyphantes graminilola (Sundevall, 1830), Singa nitidula C. L. Koch, 1844 and Trochosa spinipalpis F. O. P.- Cambridge. Evaluation of spider community shows, that 8.2 % spider species prefer naturally like habitats

The Adequacy of Some Collecting Techniques for Obtaining Representative Arthropod Sample in Dry Grasslands

The number of remarkable species on a locality is an important indicator of locality value. The ecological requirements of the rare species may help to target correct landscape management activities. Our objective was to find out if standardly used capture methods for different group of invertebrate are able to detect really representative composition of species including rare taxa. Our experiment was carried out at the Moravský kras Protected Landscape Area (Macošská and Vilémovická stráň slope) where secondary dry grasslands are typical for each investigated locality. We used five groups of invertebrates (spiders, ground beetles, rove beetles, leaf beetles and weevils) and three capture methods (pitfall traps, sweeping on vegetation and yellow Möricke traps). Arthropods were determined and classified according to their rarity. Using the three capture methods, we obtained in total 127 spider species (Areneae), 31 ground beetle species (Carabidae), 29 rove beetle species (Staphylinide), 52 leaf beetle species (Chrysomelidae) and 55 weevil species (Curculionidae).Results showed that the different capture methods significantly influenced number of detected remarkable species. It was statistically proved for spiders (P = 0.025), weevils (P = 0.038) and marginally also for rove beetles (P = 0.051). Spiders of climax (C species) and semi-natural (SN species) habitats were rather detected by pitfall traps, whereas spiders of disturbed habitats were collected by sweeping on vegetation and Möricke yellow pans eventually. Relict species of weevils (R species) were detected by pitfall traps, typical species (T species) were collected by Möricke yellow pans and expansive species (E species) were found by sweeping on vegetation

Spiders of the Vine Plants in Southern Moravia

Araneofauna of vineyards is relatively known in Central Europe but we have a lack of knowledge about araneofauna which occur directly on the vine plants. Our investigation was focused on spiders which live on vine plants, especially on the vine plants trunks. We investigated spiders in six vineyards in southern Moravia (Šatov, Mikulov, Popice, Morkůvky, Nosislav and Blučina). Vineyards were under different soil management, traps were placed on different parts of particular locality (terraced and plain) and all localities were under integrated pest management. We employed two types of cardboard traps for spider collecting during whole vegetation season. Altogether, we collected 21 spider species which belong to seven families. The most important species was Marpissa nivoyi (Lucas, 1836), which is mentioned in the Red List as vulnerable (VU) and Sibianor tantulus (Simon, 1868) which had unknown distribution in the Czech Republic. The other very interesting result is that the most common species is myrmecomorph Synageles venator (Lucas, 1836), which is scarcely recorded in such huge numbers as we documented in our study

Ground beetles (Carabidae) from slopes of Macošská stráň and Vilémovická stráň (Protected landscape area of Moravský kras, Czech Republic)

Collecting of Carabidae was conducted using pitfall traps at four sites. The first two sites (T1 + T2) were at the slope of Macošská stráň and the other two sites (T3 + T4) at the slope of Vilémovická stráň. The study was done in 2008 and 2009. At Macošská stráň in 2008, 21 species of Carabidae with the total number of 228 individuals were found and in 2009, 18 species of the total number of 116 specimens were collected. At Vilémovická stráň in 2008, 22 species of Carabidae with the total number of 1977 specimens were found and in 2009, 21 species of the total number of 623 specimens were caught. In terms of classification of relictness, Macošská stráň in 2008 was dominated by species of adaptable group A (60%), species of eurytop group (E) were represented by 35% and of relic group (R) by 5%. In 2009, the same representation of species of groups A and E (47%) were found and the species of group R were represented by 6%. Vilémovická stráň in 2008 was dominated by species of group A (52%), species of group E were represented by 43% and of group R by 5%. In 2009 also dominated species of group A (54%), species of group E were represented by 41% and of group R by 5%. In the studied area we reported four endangered species of Carabidae protected by Law (No. 395/1992 Coll.) as amended, these were Calosoma auropunctatum (critically endangered), Brachinus crepitans, Carabus ullrichii and Cicindela campestris (endangered) and two species listed under the Red List of Threatened Species of the Czech Republic (Veselý et al., 2005). One of the species is listed as vulnerable (Calosoma auropunctatum) and one as near endangered (Carabus cancellatus). Another significant species found on the monitored sites was Aptinus bombarda

Grasshoppers (Orthoptera: Caelifera) and crickets (Orthoptera: Ensifera) from slopes of Macošská stráň and Vilémovická stráň (Moravský kras Protected landscape area, Czech Republic)

In 2008 we found 21 species of grasshoppers and crickets on Macošská stráň slope and 18 species on Vilémovická stráň slope. Both slopes are located in the northern part of the Moravský kras Protected landscape area and have xerothermic character. Both slopes are influenced by pasture management. For the most comprehensive picture of Orthoptera we used a standard method (sweeping of vegetation) and nonstandard methods (pitfall traps and Möricke yellow cups). Termophilous species of Orthoptera on Macošská stráň (47%) were dominating. On Vilémovická stráň mezophilous species (46%) were dominating. The most common species were Stenobothrus lineatus (Panzer, 1796) on Macošská stráň slope and Chorthippus parallelus (Zetterstedt, 1821), Stenobothrus lineatus, Chorthippus bigutulus (Linné, 1758) and Chorthippus dorsatus (Zetterstedt, 1821) on Vilémovická stráň slope. Rare species of this assemblage were Stenobothrus nigromaculatus (Herrich-Schaffer, 1840) which was on Macošská stráň slope only and Tetrix bipunctata (Linnaeus, 1758) which has much bigger abundances also on Macošská stráň slope

Remarkable Spiders of Artificial Sandy Grassland Near Town Hodonín (Czech Republic)

Air blown sands areas and its habitats are very rare in Europe as well as many spider species, which occure there. Research was focused on spiders of sandy grassland and its ecotones near the town of Hodonín. Three lines of pitfall traps were used (one in grassland and two in its ecotones). Research took place in growing seasons of the years 2008, 2009, 2010 and 2011. Total number of collected adult spider specimens was 11743, they belong to 160 species and 21 families. It was found out, that 15 following species are included in the Red List of threatened species in the Czech Republic: Critically Endangered – Haplodrassus bohemicus Miller & Buchar, 1977, Sitticus zimmermanni (Simon, 1877), Titanoeca psammophila Wunderlich, 1993, Uloborus walckenaerius Latreille, 1806; Endangered – Euryopis laeta (Westring, 1861), Haplodrassus minor (O. P.-Cambridge, 1879), Micaria dives (Lucas, 1846); Vulnerable – Agroeca lusatica (L. Koch, 1875), Arctosa perita (Latreille, 1799), Haplodrassus dalmatensis (L. Koch, 1866), Myrmarachne formicaria (De Geer, 1778), Pellenes nigrociliatus (Simon, 1875), Scotina celans (Blackwall, 1841), Taranucnus setosus (O. P.-Cambridge, 1863), Titanoeca schineri L. Koch, 1872. Another 19 remarkable species were also found. The finding of one new species for the fauna of the Czech Republic [Sintula spiniger (Balogh, 1935)] and two new for the territory of Moravia [Mermessus trilobatus (Emerton, 1882) and Zelotes exiguus (Müller & Schenkel, 1895)] are the most important
