Mesovoid shallow substratum (MSS) of scree slopes constitutes a transition habitat between the soil and the network of voids in the vadose zone of a bedrock massif. In the present study, the vertical distribution of oribatid communities along a depth of 95 cm was studied at five forested MSS sites in the Western Carpathians, Slovakia. The sites differed in type of bedrock, topography and gradient of the microclimate and nutrients content. In all, 909 specimens were captured in subterranean traps exposed for one year. Most Oribatida represented edaphic forms, and their presence in the depth profile of the screes was accidental. Pantelozetes cavatica (Kunst, 1962) was the only species closely linked to deep subterranean environments found in the deeper part of the single limestone site studied. Species richness and the activity of oribatids along the scree profile at the sites clearly reflected the content of organic carbon in the soil substratum. The communities had very low numbers of individuals and low species richness at three sites with soil pH < 7 and organic carbon content in the upper soil layer ≤ 10%. However, they differed markedly in internal temperature dynamics. The other two sites, with a slightly alkaline soil pH and a higher carbon content, showed distinctly higher activity and a relatively uniform pattern of oribatid distribution across the depth profile. The soil pH and organic carbon content in the topsoil layer were substantial factors that determined the Oribatida diversity and vertical distribution in the forested screes.
Environmental factors, mesovoid shallow substratum, oribatid mites, subterranean environment, vertical distribution
A shallow subterranean habitat represents an environment differing from deep caves by its close contact with the upper layers of soil (under 10 metres) and thus better access to nutrients (
The majority of the mite fauna in caves and subterranean habitats consists of Mesostigmata and Oribatida (e.g.,
The present study was focused on Oribatida communities inhabiting the vertical gradient of five forested scree slopes in the Western Carpathians of Slovakia. Based on current knowledge, we assumed that the communities would differ noticeably along the environmental and nutrient gradients, and the differences in their structure would be closely related to changes in the environmental parameters of these screes.
The aims of the present study were: (1) to describe the distribution of oribatid communities along a vertical gradient at five scree sites in the Western Carpathians varying in topography and type of parent rock, (2) to clarify the presence of subterranean forms at these scree sites, and (3) to detect the response of the communities to environmental factors (internal scree temperature, soil pH and organic carbon content).
Oribatida were sampled at five sites situated in different geomorphological units of the Western Carpathians in Central Europe (Fig.
• Ardovská jaskyňa Cave (AJ) – a cave in the Slovak Karst near the village of Ardovo (south-eastern Slovakia). A southern scree slope with cornel-oak forest covered with soil and leaf litter and rocks with mosses, situated near the cave entrance. The scree profile: leaf litter and humus (0–15 cm), an organo-mineral layer with admixtures of small rocks and spaces partially filled with soil (15–75 cm) and a deeper scree layer formed by large rocks (75–100 cm).
• Belinské skaly Rocks (BS) – rocky locality in the Cerová vrchovina Highlands, near the village of Belina (south-eastern Slovakia). The site is a south-west exposed, carbon-poor volcanic scree slope with oak-hornbeam forest. The scree profile: leaf litter and humus (0–5 cm), an organo-mineral layer with a mixture of small basalt rocks and mineralized soil (5–70 cm) and a scree of small stones with spaces filled with soil (70–110 cm).
• Drienčanský kras Karst (DK) – a small karst area in the Revúcka vrchovina Highlands, near the village of Španie Pole (south-eastern Slovakia). The site is formed by a limestone ridge and a steep north-facing scree slope with beech-hornbeam forest lying a few metres below the entrance of the Špaňopolská jaskyňa Cave. The scree profile: leaf litter and humus (0–5 cm), an organo-mineral layer and soil with tiny stones (5–70 cm) and a scree of bigger rocks partially clogged with soil (70–110 cm).
• Malý Ružínok Valley (MR) – a karst valley in the Čierna hora Mountains, near the village of Malá Lodina (eastern Slovakia). A massive limestone cliff with several short caves and a north-exposed scree slope with linden-maple forest at its base are the typical features of this site. The scree profile: leaf litter and humus (0–15 cm), an organo-mineral layer (15–45 cm) and a clearly separated scree of bigger stones with spaces partially filled up with soil (45–110 cm).
• Silická ľadnica Cave (SL) – a cave with the permanent floor ice at the Silická Plateau in the Slovak Karst, near the village of Silica (south-eastern Slovakia). A west-facing scree slope with hornbeam-maple-linden-oak forest is located in the sinkhole near the cave entrance with a dense herbal cover. The scree profile: leaf litter and humus (0–10 cm), an organo-mineral layer with well developed rhizosphere and spaces substantially filled with soil (10–35 cm) and an extremely stony scree (35–110 cm).
At each site, a few metres below the top of the scree slope, a pit approximately 200 × 40 cm in area and over 100 cm deep was excavated, and the soil of the particular layers was carefully separated. Three subterranean traps, after
At each sampled site, microclimatic and chemical parameters were collected from depths of 5, 35, 65 and 95 cm. The temperature was measured continually over the sampling period at 4-hour intervals using iButton DS1921G data-loggers mounted on the walls of the plastic cups. To determine the soil chemical parameters (pH and organic carbon content), soil samples were taken once during the excavation of pits, with a total of 20 samples analysed (5 sites × 4 depths). Samples were hand-mixed, and coarse particles, such as stones and vegetation remnants, were removed. In the laboratory, the samples were air-dried for several weeks and subsequently sieved (mesh size 2 mm). Soil pH was measured potentiometrically in a 1:5 soil:deionised water suspension, and organic carbon content was analysed using the dynamic combustion method (
The Sørensen (qualitative) similarity index (
The sites were defined by similar patterns of temperature regime. More variable temperature fluctuations were noted on the soil surface horizons (0–35 cm). Deeper in the soil (55–95 cm), the fluctuations were slighter but synchronized with the climate dynamics near the surface (Fig.
The dependence between monthly temperature averages and soil depth showed various results at individual sites but a temperature was more stable with increasing depth (Table

In total, 909 individuals of oribatid mites belonging to 58 species were recorded at the study sites. The number of oribatids captured per trap ranged from 0 to 122, and the species richness from 0 to 37 (Appendix
The vertical distribution of oribatid mites reflected the distribution of organic carbon content in the soil along the vertical scree slope. The highest activity of oribatids was recorded in the upper soil layers and rapidly decreased with scree depth (Appendix

Three species – Ceratoppia bipilis (Hermann, 1804), Scheloribates pallidulus (C. L. Koch, 1841) and Xenillus tegeocranus (Hermann, 1804) – were trapped at three sites (AJ, DK and MR) and the genus Phthiracarus sp. was collected at four sites (AJ, DK, MR and SL). The most abundant species, Chamobates voigtsi (Oudemans, 1902), occurred only at the MR site. Based on the Starý‘s paper (2006), two new species were found for Slovakia: Banksinoma lanceolata (Michael, 1885) and Oribatula amblyptera Berlese, 1916. Both species were recorded only at the MR site, co-occurring with the eutroglophile Pantelozetes cavatica (Kunst, 1962).
Sites BS, DK and SL showed only few records of oribatid individuals. At the AJ site, the oribatid community was the most stratified across the depth gradient (Table

Worldwide, there are only a few studies on Acari occupying shallow subterranean environments (
Shallow subterranean habitats are highly dynamic in terms of environmental factors (
All sites with limestone bedrock were situated near caves, and we expected to find cave dwelling species in the subterranean traps. The eutroglophilous Pantelozetes cavatica, often found in Slovak caves in association with bat guano (
The dominant species differed between the particular sites, but the occurrence of the majority of them was limited to the surface soil layer (5–15 cm). Several species (Ceratoppia bipilis, Oppiella subpectinata (Oudemans, 1900), Oribatella calcarata (C. L. Koch, 1835), Xenillus tegeocranus) showed the potential to colonize deeper scree horizons from the surface. Chamobates voigtsi, defined as a psychrophilous species preferring acid forest soils, although it is able to tolerate a wider range of factors (
Compared to data on Collembola (
The present study was the first attempt to cover the diversity and distribution of soil oribatid mites along a depth profile of forested scree slopes in the Western Carpathians. Communities of Oribatida with relatively poor abundance and species richness were found to dwell at the studied MSS sites. The exception was the Malý Ružínok Valley site with suitable microclimate conditions, where more abundant oribatid communities had a clear vertical stratification. Edaphic species were limited especially to the topsoil layers rich in organic carbon. The unique status of the MSS habitat is supported by the recording of the rare specialized eutroglophilous species, Pantelozetes cavatica. The presence of this species relatively close to the scree surface underlines a function of MSS habitats as corridors for migration of subterranean oribatids towards the soil and surface dwellers to deeper subterranean spaces. Among the soil parameters measured, organic carbon content in the soil and soil pH were the governing factors affecting the diversity and vertical distribution of oribatid mites in the forested screes.
