Ranunculus pedatus is a Eurasian species with a northern distribution edge in southern Slovakia. In the nineties of the 20th century, it was assumed that the species probably occurs only near Štúrovo. Occurrence in the Hron and Ipeľ basins and several localities in the Podunajská nížina lowland between Komárno and Štúrovo was considered historical. Our research was conducted in the field and herbarium collections of 15 herbaria in Austria, the Czech Republic, Hungary, and Slovakia. Except for the well-known occurrence on salt habitats north of Štúrovo, we confirmed the recent occurrence of R. pedatus in Štúrovo town, around Chľaba village and in Ipeľ Basin (Pastovce, Tupá). The new, easternmost Slovak locality was found near the village of Koláre. Recently, 30% of all known sites were confirmed, so we propose reclassifying the species in Slovak Red List from the category critically endangered (CR) to the category endangered (EN). It occurs in salty meadows of the alliance Festucion pseudovinae (class Festuco-Puccinellietea) and in mesic meadows of alliance Arrhenatherion elatioris and Deschampsion cespitosae (class Molinio-Arrhenatheretea).

Faunistic data of rare and remarkable spider species found in vineyard terraces around Mikulov and Popice are presented. Vineyard terraces are artificial – man made – habitats that were established in the eighties of the 20th century with intention of growing grapevine. Spiders were collected by pitfall traping during 30 April – 28 October 2011 and by day and night sweeping of herb vegetation in different dates of 2011. Twenty two species listed in the Red List of threatened species in the Czech Republic were recorded. In vineyard terraces at the vicinity of Popice, 12 threatened species (CR – 2 species, EN – 3 species, VU – 7 species) were found altogether. In the vineyard terraces at Mikulov, we found 18 threatened spider species (CR – 3 species, EN – 7 species, VU – 8 species). Very rare and critically endangered Tibellus macellus Simon, 1875, Dysdera hungarica Kulczyński, 1897 and Cheiracanthium pennyi O. P.-Cambridge, 1873 belongs to the most significant findings. Besides of these threatened species, we discovered rich spectra of rare xerothermophilous spiders which created dominant and eudominant component of araneofauna – Alopecosa solitaria (Herman, 1879), Gnaphosa lucifuga (Walckenaer, 1802), Thanatus arenarius Thorell, 1872, and Ozyptila pullata (Thorell, 1875). We found that artificial habitats such as vineyard terraces are important as suitable habitats for a wide spectrum of xerothermophilous spiders of the Czech Republic.

This paper makes a faunistic contribution to knowledge of spider composition in the xerothermic habitats of the Křéby National Nature Monument which is located in Kroměříž district, eastern Moravia. Spiders were collected by four different methods during 25 April–28 October 2013: pitfall traps, sweeping of herb vegetation, individual collecting and beating the branches of shrubs and trees. In total, 1070 individuals (865 adult spiders) were collected and identified as 114 species of 19 families. The species diversity in the Křéby area is rather high, representing approximately 13% of Czech araneofauna. Of the identified species, five are listed in the Red List of Threatened Species in the Czech Republic. These included critically endangered Dysdera hungarica Kulczynski 1897, endangered Alopecosa solitaria (Herman, 1879), Cheiracanthium montanum (C. L. Koch, 1877) and vulnerable Lathys stigmatisata (Menge, 1869) and Haplodrassus dalmatensis (L. Koch, 1866). The findings of Alopecosa solitaria and Dysdera hungarica belong to the northernmost occurrence of these rare species in the Czech Republic. In general, the great richness of spider fauna and the occurrence of rare and threatened species for Czech region confirm the high biotic value of the investigated area. In addition, the author discussed management methods of the locality and suggest management conservation system for slowing down the succession rate on overgrown places.

Two xerothermic localities in Moravský kras were investigated from March to November 2008. Altogether 183 species of beetles from 13 families (except Carabidae published separately) were collected in Macošská and Vilémovická stráň slopes using several collecting methods: pitfall traps, sweeping of vegetation and Möricke traps. Both slopes are located in the northern part of the Moravský kras and are influenced by pasture management. Altogether we found 21 species listed under Red list of threatened species in the Czech Republic, it is approximately 11.5% of all collected species. The most important species (two critically endangered – CR: Eumolpus asclepiadeus (Pallas, 1776), Sphaeroderma rubidium (Graëlls, 1853) and six endangered – EN) belong to family Chrysomelidae. Another endangered collected species belong to families Curculionidae and Staphylinidae.

Current and historical occurrence as well as coenotic affinity and ecology of <em>Carex secalina </em>in the Czech Republic and Slovakia are presented. The study is based on revision of herbarium specimens from 25 herbaria, literature data excerption and a field survey carried out during 2004-2010. Altogether, 168 sites were documented in the Czech Republic divided to two separate areas. Stabile occurrence trend was found in last decades, because 45 localities were documented in period 1975-1999 (27% of sites) and recent occurrence was confirmed at 42 localities (24% of sites). On the basis of our current knowledge the species was included into the IUCN threat category VU (vulnerable). In Slovakia, 19 localities of the species were recorded in total, but only 4 sites were confirmed recently (21% of sites recorded). However, only a small number of individuals was recorded there (less than 50 individuals in total) and half of this sites is acutely threatened by destruction (ploughing, secondary succession). Therefore, the <em>C. secalina </em>status in the Slovak Red List was changed to the IUCN category "critically endangered" (CR). Results of the study are summarised in the maps of historical and current species distribution. <em>C. secalina </em>usually occurred in halophytic grassland communities, especially in association <em>Agrostio stoloniferae-Juncetum ranarii </em>Vicherek 1962. However, it may occur in many other communities which suggest that the species had not well-defined coenotic relationships. On the basis of our knowledge, we consider <em>C. secalina </em>as an obligate halophyte.

Results of an analysis of dipteran pests composition and changes of their importance in agricultural, horticultural and ornamental plants during the 20th century are given. Even 89 Diptera species have been registered as pests of these plants (1.1 % of all species known in the Czech Republic). Of these ca 14 (16%) species caused regular and important and other 23 (26%) species occasional damages. The remaining 52 (58%) species are unimportant, local and sporadic pests. Only small changes (10% maximally) in the species composition of more important dipteran pests have been registered during the century.

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.

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.
