Interior spaces of the forested rocky debris (MSS) represent a transition zone between the surface and deep underground spaces and a place of animal adaptation to underground life. They serve as a refuge for relict fauna as well. The study was conducted in the limestone scree slopes in Sivec National Nature Reserve (Čierna Hora Mts, Western Carpathians, elevation about 500 m a. s. l.) covered by linden-maple forest from September 2008 to November 2009. The effort was to define the vertical and seasonal aspects of invertebrates and temperature regime. Invertebrates were collected by using subterranean traps (plastic cups with 4% formaldehyde, inserted into the depths 5-95 cm through a plastic tube), which were checked monthly. Almost 26,000 specimens were trapped. Arthropods highly dominated over gastropods and earthworms. Collembola (67.61%) and Acarina (15.55%) were eudominant. Macrofauna was represented mainly by larvae of Holometabola (7.55%) and adult Diptera (5.11%) and Coleoptera (1.13%). All these groups were captured along the total depth gradient. Coleoptera were studied in more details. Among 11 Coleoptera families, Staphylinidae predominated and were captured at all levels. Rather high species diversity was found: 67 spp. excluding common epigeic fauna. Some species supposed to be subterranean, e. g., Bryaxis frivaldszkyi slovenicus, Duvalius bokori valyianus and Omalium validum. Activity of most invertebrate groups decreased significantly with depth (prevalence of surface fauna), but it was not terminated at 1 m under surface; the same was true for beetles, both in activity and diversity. Conspicuous fact is that a mass of subterranean species were traced also close to the surface (35 cm), i. e., probably it is not necessary to put the traps as deep as in this study. Seasonal climate changes affected the activity of invertebrates which was the highest at the end of spring and the lowest during winter, but it was not completely interrupted. Microclimate was characteristic without major temperature fluctuations on the surface. It was stable deeper along with increasing average annual temperature. High diversity and the occurrence of rare faunistic elements as well as specific habitats of MSS are perspective study objects and they merit care; mature design of the next studies considering the effect of season and depth of traps deposition shall do them more effective and less laborious. © 2012 Versita Warsaw and Springer-Verlag Wien.

We evaluated surface-dwelling Coleoptera with special reference to ground beetles (Coleoptera: Carabidae) using pitfall traps across fourteen stands of grasslands invaded and non-invaded by invasive goldenrods (Solidago canadensis L. and S. gigantea Ait.) over a 3 year period. We analysed differences in assemblages of invaded and non-invaded grasslands and tested responses of surface-dwelling beetles and carabids to invasion of goldenrods. We identified 29 Coleoptera families and 91 Carabidae species. Solidago invaded grasslands showed significantly higher activity-abundance of rove and carrion beetles and supported greater diversity and significantly higher evenness of surface-dwelling Coleoptera and the number of sampled families and individuals was higher too. We found lower taxonomic richness and significantly lower activity-abundance of carabids across goldenrods stands. Several less common Carabidae species and significantly higher representation of stenotopic brachypterous habitat specialists were also observed within invaded stands. We confirmed that differences in plant cover connected with invasion of goldenrods, soil moisture and abandonment of invaded habitats are the driving mechanisms of changes in surface-dwelling Coleoptera and ground beetles assemblages composition across Solidago invaded grasslands. Overall, changes of grassland biotopes connected with invasion of goldenrods significantly alter Coleoptera families and Carabidae assemblages, but not necessarily reduce diversity. © 2014 Springer International Publishing Switzerland.

Man-made sites are found to often provide biodiversity refuges in anthropogenically impacted landscape and offering valuable analogues of natural habitats. We surveyed surface dwelling soil macrofauna and ground beetles (Coleoptera: Carabidae) assemblages by pitfall trapping across the eight stands of waste dumps and eight comparative biotopes in Eastern Slovakia. To our knowledge, this is the first such survey. During 18 weeks period in 2011 and 2012, a total of 38.814 individuals were trapped belonging to 17 soil macrofauna orders, 38 Coleopteran families and 98 Carabidae species. We analysed differences in assemblages of waste dumps and comparative biotopes and tested responses of orders, beetles and carabids to selected environmental variables. Assemblages collected from waste dumps had consistently higher diversity than their surrounding habitats, waste dumps equally showed higher proportion of slow-moving sapro-phytophagous orders and large wingless ground beetles colonizing native habitats. Ten rare ground beetles species were only captured from waste dumps. No clearly, unambiguous pattern was observed concerning distinctions in assemblages in relation to selected environmental variables, however, trees and shrub vegetation as well as soil moisture apparently affected community distinctions between studied habitats. We concluded, that reclaimed waste dumps as well as illegal waste dumps under different stages of succession could support surface dwelling soil macrofauna functional and the ground beetle species diversity in the agricultural landscape. © 2015 Elsevier B.V.
