Abstract
Red List of wide spectrum of invertebrate groups in the Czech Republic according to the IUCN criteria.
... Interestingly, the species that were very abundant in the less polluted locations (1 and 5) such as P. decorum, S. obscura, or P. cupreus occurred in much lower numbers at locations with higher RE levels. At locations 2 and 5, the occurrence of Carabus scabriusculus, which is included on the Red List of the Czech Republic [28] as vulnerable, was recorded. The species distributions in relation to RE content as derived from CCA are shown in Figure 3. ...

Five meadows along the Litavka River highly contaminated with heavy metals from mining were sampled for insects and spiders using pitfall traps. The sites are in the Příbram region of central Bohemia, Czechia, which was previously reported as one of the most polluted areas in Europe due to intensive mining and metal processing. The determination of pseudo-total risk elements in soil revealed that all the sampled sites were contaminated with heavy metals, especially As, Cd, Pb, and Zn, with levels ranging from moderate to extreme. The trap results showed a total of 1142 beetles from 21 species, 946 ants from 16 species, 548 spiders from 28 species, and 96 harvestmen from 3 species. With the exception of the scabrous ground beetle, Carabus scabriusculus, all captured specimens were species common to the wet meadows and forest edges of Czechia. With respect to species richness, the dominant spider and beetle taxa were less abundant at the heavily polluted locations than at the moderately polluted locations. In the case of ants, however, there was no relationship between contamination level and abundance or species richness. Thus, it is worthwhile recording and analyzing the differential changes in abundance of the dominant spider and beetle species in polluted areas.
... The problems commented on by Gepp and Bregant (1986) and Gepp (1995Gepp ( , 2003, who proposed that the presence of S. curvatum is harmful to the native S. destillatorium, may then not be as important as was presented by the authors and certainly does not concern nesting sites. Additionally, Lukáš et al. (2006) and Hejda et al. (2017) confirmed recent spreading of S. destillatorium in the Czech Republic and Slovakia although both S. caementarium and S. curvatum occur in these countries, too. ...
Sceliphron caementarium and Sceliphron curvatum are non-native species in Europe with former distributions in North America and Asia, respectively. Both species create nests of mud that are usually located inside, on the surface of, or near buildings. Though both species have been studied many times, knowledge on their nesting biology is based on a few studies with small numbers of non-analysed observational data. By collecting information on 123 S. caementarium nests, 341 S. curvatum nests, and 75 nests of the most widespread native species, Sceliphron destillatorium, the nesting place preferences of the wasps were evaluated. The three species do not differ in their nest placements within settlements, in the sizes of the settlements where they nest, or in their nesting locations, and they differ only slightly in the heights of their nests above the ground. The main difference is that S. curvatum nests are usually hidden inside buildings, while the other two species mostly create nests on the surfaces of buildings. Thus, S. curvatum could negatively affect its native relatives due to its high population density and competition for prey, but not due to the competition for nesting sites. Neither non-native species represents any threat to crops or landscapes; the species have only limited negative effects, such as building nests in or on peoples’ houses, carrying mud and spiders to these locations, and annoying people with their loud buzzing during nest building and provisioning. They are both regarded to represent minor threat according to SEICAT classification.
Implications for insect conservation
Both two non-native species are only very little harmful for the native species and probably also for other species of bees and wasps with similar nesting biology. Their harmfulness is much lower than that of other well known invasive insects (Harmonia axyridis and Vespa velutina for example).
... This may mean that in Poland the northern range limit passes through the Świętokrzyskie Mountains. Rugilus mixtus is included in the Red List of the Czech Republic's beetles with the status EN (endangered) (Farkač et al. 2005). Buchholz & Melke (2018) suggest that this species can be classified as an indicator species for determining forest naturalness. ...
Rugilus mixtus (Lohse, 1956) is a rare species of Staphylinidae, found to exist only in a few European countries. In Poland, it was known from only three sites. Having analysed museum collections, we report 9 new locations. On the basis of the available literature and our observations of this species, we present its detailed ecological requirements, which, to date, are not fully recognized. The species is very likely to occur in humid biotopes, where the dead, rotting trees or stumps are essential elements and the vast majority of known sites are located in naturally important areas. Therefore, we suggest that Rugilus mixtus may be used as an indicator species in studies aimed to evaluate the naturalness of forest. In order to facilitate the correct identification of this species, we have used illustrations and photographs of their aedeagi to create a key for four similar species of the genus Rugilus occurring in central Europe.
Currently, plant invasions affect native ecosystems across the Earth. Although much attention has already been paid to their effect on local communities, we still lack basic information on the associations between alien and local species. Here, we present the results of our survey of pollinators of the invasive plant Heracleum mantegazzianum (Apiaceae) in central Europe. At 20 sites within the westernmost part of the Czech Republic, which is strongly affected by the invasion of H. mantegazzianum, pollinators on the flowers of H. mantegazzianum were examined and compared to the species composition of pollinators on native vegetation in the surrounding area. While the flowers of H. mantegazzianum were frequently visited by high abundance of insects, the communities of H. mantegazzianum pollinators were relatively species poor, and the proportion of abundances of H. mantegazzianum pollinators was very uneven, with few species of generalist Diptera and the honey bee (Apis mellifera) dominating over all other flower visitors. Significantly larger species of the family Syrphidae visited flowers of giant hogweed than of other plants. Thus, giant hogweed is not a necessary part of flower communities for flower visiting insects, and it should be eradicated because of its negative effects on other plants, landscape and humans. Our results highlight the need for more detailed studies on direct interactions between alien plant species and native pollinator communities as well as indirect interactions between alien plants and native plants through competition for pollinators.
Background
Zygaena carniolica is both a flagship and an umbrella species of calcareous grasslands, which are under decline in central Europe. It used to be a very common species but is currently red-listed.
Methods
We studied the distribution of Zygaena carniolica in eastern Bohemia in 2010 and 2021 based on historical and recent findings. Moreover, we studied the associated floral composition and lepidopteran fauna by means of several site and landscape variables.
Results
Our results revealed a notable decline in the number of localities in which Zygaena carniolica was present. The presence of the burnet moth depended on the presence of bare soil and the host plant Onobrychis viciifolia at the studied localities. Moreover, the presence of Z. carniolica was correlated with a specific plant and lepidopteran species composition.
Discussion
The presence of Zygaena carniolica declined due to the loss of suitable habitats. Its natural and seminatural habitats are often converted for different land uses. Their management abandonment led to unsuitable vegetation succession and the loss of the once-cultivated preferred host plant Onobrychis viciifolia. Stable populations of Zygaena carniolica might be achieved only in connection with appropriate habitat management. Conservation measures should be taken into consideration, given the dramatic decline in xerothermic species richness in the last 11 years.
Implications for insect conservation
The key to reversing this trend is restoring traditional grassland management in the form of nonintensive pastures and hay making. Moreover, some nontraditional management tools might be used to restore early successional stages of vegetation.

First faunistic records of critically endangered meloid beetle Meloe uralensis in Central Moravia (Czech Republic) and notes on its biology and conservation are presented. Discovered locality Němčice nad Hanou is northernmost occupied place in the Czech Republic. During three years, 24 adults were observed. They were active from mid- March to the end of April under sunny conditions with temperature 13-24 °C. Most of adults were observed in margin of fields (running or eating cereals in most cases, less frequently sunning on higher vegetation). Several potential hosts (bees) were observed: Andrena flavipes, A. subopaca, Colletes cunicularius, Lasioglossum lineare, L. malachurum and L. morio. Discovered locality represents unique island of heterogeneous mosaic of diversely managed landscape in region with prevailing uniform arable land. The mosaic consists of small-size patches (less than 1 ha) of extensive fields, orchards, gardens etc. Besides M. uralensis, sympatric occurrence of several threatened species bound to steppe or forest steppehabitats underlines high biological value of the locality. Therefore, maintenance of current extensive management seems to be appropriate conservation measure for M. uralensis.
Twenty-three sites within the Slavíč river basin (Silesia, Czech Republic) were surveyed to obtain up-to-date information on water beetles in the area. In total, 46 species comprising eight families were recorded. Significant findings included Ochthebius melanescens Dalla Torre, 1877, Hydrocyphon deflexicollis (Müller, 1821) (both endangered), Hydraena morio Kiesenwetter, 1849, Eubria palustris (Germar, 1818) (both vulnerable), Hydraena minutissima Stephens, 1829 (near threatened) and Elodes pseudominutus Klausnitzer, 1971 (data deficient). The Slavíč water beetle assemblage consisted mainly of typical rheophilic species, many characteristic for cold, mountainous waters, the most common beetles recorded being representatives of the families Elmidae and Hydraenidae. The species spectrum was significantly enriched by species found in non-riverine habitats along the Slavíč River floodplain (e.g. springs, wetlands and ponds), with representatives of the families Dytiscidae, Haliplidae and Hydrophilidae dominating.
All available records of Mymaromma anomalum (Blood et Kryger, 1922) (Hymenoptera: Mymarommatidae) from the Czech Republic are reviewed. The occurrence of this species in Bohemia is confirmed and its occurrence in Moravia is published for the first time. Mymaromma anomalum has been found throughout the Czech Republic. Collecting sites range from lowlands to highlands (215-595 m a. s. l.) but its presence in Scandinavia suggests in may also occur at higher altitudes in the Czech mountains. We propose to include this species as "least concern" in the Red List of the Czech Republic.
Urban areas have increased greatly in recent decades, which has resulted in habitat loss. However, the promotion of urban green spaces could have a profound effect on biodiversity. Traditional fruit orchards are an important land-use type with the potential to host myriad organisms.
Our goal was to determine the most important factors that influence orchard biodiversity in the million city of Prague (the capital of the Czech Republic). We used a multitaxon approach to evaluate the effect of orchard restoration in a landscape context.
Restoration had a positive impact on species diversity, specifically, the diversity of orthopterans and butterflies. Moreover, landscape context determined the biodiversity of orthopterans, butterflies, and birds but not that of lichens.
Our study underlines the importance of both the internal and external structures of traditional fruit orchards for species richness and composition. The results of our study support the restoration of traditional fruit orchards as a suitable management practice for promoting city biodiversity.
Furthermore, orchard restoration can improve the attractiveness of suburban areas. Such areas often lack sufficient urban greening. Thus, restoration in these areas can also increase future recreational value.
