Resumen
Oribatid mites (Acari, Oribatida) in selected caves of the Kraków-Wieluń Upland (southern Poland) This paper describes and compares the species composition and community structure of the oribatid mite fauna of 5 caves in the Kraków-Wieluń Upland (Wyżyna Krakowsko-Wieluńska). We also compare oribatid communities in 3 chosen caves with oribatid communities in the soil and litter (leaves, dead wood, bat guano) in the vicinity of the cave entrances. Three hypotheses were tested: (1) oribatid communities from the soil and litter near the caves differ from the communities inhabiting caves; (2) the composition of oribatid communities depends on cave size; (3) the cave communities strongly depend on microhabitat quality and diversity. We collected 1112 adult oribatids from caves and 838 from the soil and litter near the caves. Oribatid communities in the caves were different from the soil communities. Litter, guano and dead wood were the microhabitats that affected oribatid communities significantly. In the other cave microhabitats (soil and mud), oribatids were infrequent. Cave size affected the oribatid community structure.

Resumen
Oribatid mites (Acari: Oribatida) are one of the most numerous and dominant groups of soil inhabitants that play an important role during soil formation and its biological processes. The paper presents a full list of oribatid mites known of Vietnam (excluding Acari: Astigmata) based on the collected and identified species as well as on literature records from 1967 to 2019. Totally, 726 plus one oribatid species belonging to 245 genera, 90 families, and 41 superfamilies, together with the specimen’s data have been recorded in Vietnam. These oribatid mites species are identified and analyzed along with their distributions known according to the eight natural and man-made factors, including (1) natural region, (2) soil type, (3) climate zone caused by elevation above sea level, (4) habitat type, (5) distance to the sea, (6) climate season, (7) soil vertical distribution, and (8) oribatid body size. This will be an important scientific basis for further analysis on the relationship of the formation of oribalid mite complexes under the influence of natural & man-made factors, contributing to sustainable management of soil ecosystem in Vietnam.

Resumen
The objective of this work was to compare the oribatid mite and springtail communities in three plots with different soil use - Coffee (CP), secondary vegetation or fallow fields (acahual, A) and a cloud mountain forest (CMF) - within a coffee plantation located in Santa Maria Huatulco, Oaxaca State, Mexico. In each plot 20 samples (10 of soil, 10 of litter) were taken and processed in Berlese funnels. The extracted fauna was preserved in 70% ethanol. A total of 3,031 oribatid mites belonging to 33 species, and 1,177 specimens of springtails belonging to 43 species, were collected. The number of species recorded was: 27 at CP (14 oribatids; 13 springtails), 44 at A (19 oribatids; 25 springtails) and 62 at CMF (32 for each group). A total of 26 oribatid and 27 springtail species was found in the soil, and 25 oribatid and 32 springtail species were found in the litter. The most abundant species were the oribatids Rostroztes foveolatus (Haplozetidae), Tectocepheus sp. (Tecocepheidae), Karenella sp. (Oppidae), Atropacarus (Hoplophorella) cf. fonseciai (Phthiracaridae), Epilohmannia pallida americana (Epilohmannidae), and the springtails Ceratophysella cf. gibbosa (Hypogastruridae), Mesaphorura sp. (Tullbergidae) and Proisotoma cf. minuta (Isotomidae). Fourteen families and 18 species of Oribatida species and 5 families and 34 species of Collembola were recorded for the first time for the State.

Resumen
Suborder Oribatida is land-dwelling group of mites distributed across different geographic regions of the world. This study shows the assessment of diversity, richness, evenness, and abundance of families of Oribatid from uncultivated and cultivated soils collected from ten different localities of Punjab, Pakistan. Overall, 9 families of Oribatida were observed in both soil types having Oribatellidae, Oppiidae, and Scheloribatidae as dominating families. Uncultivated soil had more richness (S=07), abundance (46.01 ± 2.61) and Shannon diversity index (H’=1.77 ± 0.03) compared to cultivated soil with richness (S=5), abundance (25.35 ± 1.14) and Shannon index (H’= 1.47 ± 0.03). Maximum abundance value of oribatid mites (62 ± 11.87) was recorded from Murree for uncultivated soil while in case of cultivated soil, it was recorded from Faisalabad (29.83 ± 7.28). The maximum family richness of Oribatid mites was observed in Faisalabad and Chakwal (S=07) while minimum family richness (S=05) was observed from T.T. Singh.

Resumen
The study of morpho-ecological organization of oribatid mite communities (Acariformes, Oribatida) inhabiting forest litter of recultivated areas in steppe zone conditions of Ukraine was performed. The role of the forest and forest floor litter in optimization of the ecological situation on degraded lands was demonstrated. The function of environment creation by oribatids, as primary destructors of dead plant matter, supporting such ecosystem services as soil fertility improvement and nutrients turnover was highlighted. The research was performed within different stratigraphic types of bulk edaphotops in the recultivated plot of “Pavlogradskaya” colliery (Pavlograd, Dnipropetrovsk region, Ukraine) planted with red juniper (Juniperus virginiana L.). Withdrawal and collection of mites was performed with thermoeclector. For determination of the domination structure in the mite communities, the Engelmann scale was used. Adaptive (morpho-ecological) groups of oribatid mites were diagnosed by Krivolutsky. It was established that the number of species of oribatid mites in the forest litter of the studied red juniper plantation varied from 16 to 25. Average density of oribatid mites varied from 4,720 to 25,327 ind./m2. Among such morpho-ecological groups as soil surface inhabitants, small soil pore inhabitants, deep soil forms, floor litter inhabitants and unspecified forms, identified in the coniferous litter, the share of unspecified forms increased from loess-like loam type (21% of total amount) to Calcic Chernozem types with different stratigraphy (41.0%, 70.0% and 70.4% accordingly). Deep soil forms in the forest floor litter of the studied red juniper plots were not identified for any of recultivation types. The obtained results expand our understanding of the role of oribatid mites in the processes of ecological rehabilitation of disturbed ecosystems in the conditions of modern nature management.

Resumen
Abstract Intensively used forest nurseries are characterised by degradation processes that lead to a drop in the quality of seedlings. The main reason of this problem is a decrease in biological soil diversity. Therefore, an attempt of nursery soil enrichment by introducing ectohumus – as compost and fresh litter – from the pine forest was carried out. The research was carried out in 2009–2011 in the Bielawy forest nursery near the city of Toruń, Poland. The objective of the study was to determine the impact of organic fertilisation (compost made up of forest humus) and mulching using fresh ectohumus on the density and community composition of Acari mites and on species composition of oribatid mites (Oribatida) in the nurseries of silver birch and Scots pine. Mites, especially oribatid mites, were treated as bioindicators of soil biological activity. Research has shown that mulching using fresh ectohumus caused a multiple increase in the density of mites, especially in saprophagous mites Oribatida. Oribatid mites were clearly more numerous in birch cultivation than in that of pine. Overall, 27 species of oribatid mites were found. Mulching resulted in a significant growth in species diversity in both cultivations. The most numerous oribatid mite in the area under the study was Oribatula tibialis. This species was present in all plots and showed clear preference for birch cultivation. Tectocepheus velatus and Oppiella nova, common and known to be present in a variety of environments, were slightly less numerous.

Resumen
The article analyzes the taxonomic diversity, dominance structure, spectra of morpho-ecological types, biotope complexes and groups of oribatid mites of mesophilic grasslands on Transcarpathian lowland. Prior to our works, there were almost no studies of the oribatid communities of the studied area. The research plots located on the sorrounding areas of the city of Mukachevo and the village of Kalnyk of the Mukachevo district. Soil samples selected for 2013-2014. The geographical coordinates of the first meadow are: 48º22.79' N, 22º40.14' E, and the second one is 48º30.86' N, 22º34.65' E. The total area of the first biotope is 0.45, and the second is 37.5 hectares. In relation to the humidity of the substrate, this type of biotope is characterized by mesophilic conditions. Extraction of mites from soil was carried out using Tullgren funnel method. Permanent preparations were prepared. Identification of the specimens was carried out using a microscope (Olympus BX 51). Oribatid mites of the investigated mesophilic grasslands are represented by 26 species from 22 genera and 16 families. The families Oppiidae and Scheloribatidae are the most represented. The average density of oribatid mites of the mesophilic grasslands on Transcarpathian lowland has relatively small values (3.7 thousand specimens per m2). The dominant species include Punctoribates punctum (C. L. Koch, 1839) and Ceratozetes mediocris Berlese, 1908. They together make up 44% of the total density of oribatids. Margalef, Menkhinik, Simpson, Shannon and Berger-Parker indices were calculated. 10 morpho-ecological types of oribatid mites were found on mesophilic grasslands. Oribatids - inhabitants of small soil crevices – predominate. Representatives of five biotope complexes (euryoecic, hygrophilous, hygro-mesophilous, mesophilous and xerophilous) and four biotope groups (eurytopic, forest, forest-meadow, meadow) were identified in the structure of ecological groups of Oribatids. Mesophilous and meadow species of oribatid mites have the largest share.

Resumen
The article discusses the results of research of soil microbiomass and communities of soil inhabiting oribatid mites in permafrost alas meadow-chernozem soil. This study allowed assessing the features of the state and main characteristics of the metabolic activity of microbiomass and the number and species diversity of the community of oribatid mites. In general, permafrost meadow soils of Central Yakutia are characterized by lower values of microbiomass and specific metabolic activity of this biomass than meadow soils of the European part of Russia, but higher values of microbial biomass and respiratory activity than permafrost taiga soils of Central Yakutia. The total average number of carapace oribatid mites in the meadow alas soil was 8640 sp/m2. This indicates a relatively high degree of favorable environmental conditions for communities of soil inhabiting oribatid mites in the studied ecosystem. The conducted research allows concluding that soil-microbiological and soil-zoological methods can be successfully used in the environmental monitoring of permafrost meadow soils of Central Yakutia.

Resumen
Oribatid mites are distinguished by high taxonomic diversity and abundance in almost all natural zones; they are used as an indicator group of microarthropods in the study of natural landscapes and anthropogenically disturbed ecosystems. In the karst landscapes of the North, the oribatid mites are very poorly studied. The aim of this study was to investigate the diversity of soil types, plant communities, and oribatid mites in karst relief forms in the conditions of the northern taiga forests. The material was collected in July 2020 in the karst landscapes of Timan Ridge, found in the European northeast of Russia. The research sites were located in the profile of the karst crater and in the profile of the slope in the Ukhta River Valley. A sedge wetland community, and pine–bilberry–green-moss forest, located in the depression between glacial hills and uplands were also examined. A total of seven sites were examined. Geobotanical descriptions were made by standard methods, descriptions of the soil profile, and samples of the soil microfauna; 12 in each site were collected. A total of 51 oribatid mite species from 39 genera and 31 families were found. The highest taxonomic diversity of oribatids was noted in forest phytocenoses located in the upper part of the karst crater slope, the lower part of the karst crater slope, and on rock outcrops in the lower part of the slope in Ukhta river valley. Ordination of the oribatid mite community by NMDS method showed the association of sites S3, S4, and S5 located on the slope of the karst crater in one group, and sites S6 and S7 located on a slope in the Ukhta River Valley, as well as S2 (pine–bilberry–green-moss forest located in the depression between glacial hills and uplands), in another group. The swamp community was located separately from other communities. Species of oribatid mites, which created the specifics of each community, were noted. The specifics of the population of oribatid mites of karst landscapes were that along with the features of fauna, characteristic for zonal north-taiga forests (the predominance of polyzonal widespread species) were found the “conditionally southern” species, the main area of distribution of which is located in lower latitudes. The study provides the basis for future studies of poorly known oribatid mites of karst landscapes of Northern Europe.

Resumen
The distribution of mites on the soil surface of different types of pastures, the invasion of oribatids by monies larvae are dependent on climatic and weather conditions of the area, as well as the degree of infection with monies of the grazed livestock of ruminants. Seasonal dynamics of population density of oribatid ticks on natural and artificial pastures of two livestock farms of the Ivanovo region is studied. In soil and grass samples 5 species of shell mites were identified: Scheloribates laevigatus, Scheloribates latipes, Punctoribates punctum, Punctoribates sellnicki and Ceratozetes mediocris, cysticercoid-infested monies. Dominant species were representatives of the genus Scheloribates (65,8%), subdominant – genus Punctoribates (26,7%). The population density of oribatid mites on natural grassland pastures in may averaged 198±17,8 specimens per 1 m2 with cysticercoid monies equal to 3,39%. In June-July, the number of oribatids ranged from 249±23,5 – 298±31,2 specimens on 1 m2 at EI = 4,47–6,9% respectively. The greatest number of oribatids was found in August-September: 343±39,4 – 368±42,4 specimens per 1 m2 at EI = 8,7–9,2%. In October the population density of oribatid mites decreased to 201±28,4 individuals per 1 m2 at EI = 4,54%. Artificial (cultural) pastures, the number of oribatid mites does not exceed 108±9,3 individuals per 1 m2. The contamination of the oribatids with cysticercoids of moniesia on these pastures has not been found. The research results make it possible to assume a high degree of invasion of ruminants by moniesia when grazing them on natural meadow pastures and plan preventive measures.

Resumen
Effect of cattle liquid manure fertilization on the yield of grassland and density of soil oribatid mites (Acari, Oribatida) The effect of cattle liquid manure without and with Effective Microorganisms (EM) on the hay yield and density of soil Oribatida was investigated in a lowland meadow. Fertilization of the meadow with low and medium doses (30 m3·ha-1 and 60 m3·ha-1) of liquid manure increased the hay yield, more with EM than without them. However, the highest dose (90 m3·ha-1) of fertilizer did not change hay yield, as compared to the control plot. All doses of cattle liquid manure reduced the density of oribatid mites, distinctly more without EM than with them. This suggests a favourable influence of EM on these mites. Among the Oribatida, Liebstadia similis, Scheloribates laevigatus, Eupelops occultus, and Achipteria coleoptrata, were abundant, while other species were infrequent. The community of Oribatida was dominated by adults.

Resumen
The effects of partial and clear-cut harvesting on abundance and community composition of forest floor microarthropods and oribatid mites were investigated in conifer and deciduous stands of the mixedwood boreal forest. Soil samples from clearcuts, strip-cut corridors in a partial cut, green-tree retention patches in a partial cut, and uncut control sites were collected 2.5 years after harvest and microarthropods were extracted, enumerated, and identified. Densities of microarthropod suborders were lower in the strip-cut corridors of the deciduous stands and significantly lower in the suborder Oribatida (oribatid mites). Changes in microarthropod community composition, decreased relative abundance of prostigmatid mites, and increased relative abundance of mesostigmatid mites were observed in corridor and clear-cut treatments. Lowered abundances and changes in community composition are likely due to compaction of the forest floor during harvesting. Selected oribatid mite species showed significantly lower abundances in clearcuts than in uncut sites, but diversity indices for oribatid mites were generally not significantly different between uncut sites and clearcuts. Changes in oribatid mite communities following harvesting were thus more quantitative (absolute abundance) than qualitative (diversity, composition), and as a result, use of oribatid mites as biological indicators of disturbance is limited because of the lack of changes in species composition.

Resumen
The continued use of waste water for irrigation of agricultural fields in Egypt may lead to accumulation of heavy metals in soils and adverse effects on soil-living communities. We investigated responses of oribatid communities to heavy metal contamination in mango plantations irrigated by the Ismailia canal in the Suez region. Mean concentrations of heavy metals determined in irrigation water were considerably above the recommended levels. Concentrations of metals in agricultural soil were however below the permissible levels. A comparison with concentrations of a typical uncontaminated soil in this area revealed that the Ismailia water canal used for irrigation of agricultural land has elevated levels of heavy metals. The results of our ecological survey showed that the abundance and structure of the soil oribatid communities were not influenced by levels of heavy metals in the soil. We also showed that the diversity index can be a valuable tool for assessing the possible impact of pollutants on different species of oribatid mites. The oribatid species appeared to be accumulating different amounts of heavy metals when characterised by their bioconcentration factors. Most species were poor zinc accumulators. The accumulation of heavy metals in the body of oribatids was not strictly determined by their body size or by the trophic level. In conclusion, our study showed that mango plantations impacted by waste water from the Ismailia canal are accumulating heavy metals in their soils above the background concentrations, but ecological effects on soil-living communities are not apparent yet.

Fauna and ecological diversity of oribatid mites of hygrophyte grasslands on Transcarpathian lowland is considered in the paper. For Transcarpathia, such studies have not been conducted before. For hygrophyte grasslands 45 species of Oribatida (25 families, 34 families) are registered. The most numerous among detected taxa were Platynothrus peltifer, Ceratozetes mediocris and Oppiella nova. It has been established that dominant role belongs to the surface-soil morpho-ecological group of oribatid mites. In the ecological structure, predominant role is inherent of hydrophilous and eurytopic species.

Resumen
Comparison of Earthworms (Lumbricidae) and Oribatid Mite (Acari, Oribatida) Communities in Natural and Urban Ecosystems This study investigates earthworm and oribatid mite communities in urban, semi-natural and natural ecosystems of Tbilisi (Georgia). Ten species of earthworms and 100 species of oribatid mites were registered in 45 soil samples. Two species of oribatid mites, Microzetes auxilaris Grandjean, 1936 and Multioppia laniseta Moritz, 1966, are new for the Caucasian fauna. We hypothesized that species number and abundance of invertebrate animals tend to decrease from natural to urban ecosystems. The hypothesis was supported only partially. Number of species of oribatid mites and earthworms decreased together with increase of urbanization, whereas abundance showed no significant changes due to high density of stress tolerant and ubiquitous species in urban sites. Accordingly, species abundance is considered to have minor indicatory value. Our studies support ecological "time-hypothesis" in a way that older (natural) sites were presented with more diverse fauna than recent (urban) ones. Statistical analyses showed that studied ecosystems should be grouped in two rather than three categories: in urban and natural ones.

Resumen
Effect of cattle liquid manure fertilization and disinfectant on seasonal dynamics of Oribatida (Acari) in a permanent lowland meadow in Poland Oribatid mites have a favourable influence on soil fertility. The effect of cattle liquid manure fertilization (40 and 80 m3 ha-1) and disinfectant at 3 concentrations: 0.50% (fungicidal), 0.75% (bactericidal), and 3.00% (viricidal) on seasonal dynamics of Oribatida was investigated in a permanent lowland meadow in Poland. Cattle liquid manure without disinfectants reduced the density of oribatid mites, especially in the spring, except for a higher dose of fertilizer in the summer, which increased their density compared to the control plot. This fertilizer treated with the disinfectants differentiated the density of oribatid mites, i.e. reduced or increased it, compared to the control plots. However an increased density was observed only in summer, after application of the higher dose of fertilizer with fungicide or viricide. In the control plot, some species (Achipteria coleoptrata and Parachipteria bella) were rather abundant in the spring and autumn, and some other species (Liebstadia humerata and Scheloribates laevigatus) only in the spring. Cattle liquid manure and disinfectants changed the dynamics of density of these species. In the control plot the adults were slightly more abundant than the juveniles in the spring, but the juveniles dominated in the summer, and the adults dominated again in the autumn. Cattle liquid manure and disinfectants changed the age structure of oribatid mites. None of the experimental variants was favourable for Oribatida in all seasons.

Resumen
Abstract The present publication provides a review of the soil mite (Acari; Oribatida) community’s structure and the connection between changes in environmental factors and oribatid mite diversity in the limestone quarry of Saskhori and its adjacent areas. Overall, 52 species were recorded during the study. The most abundant oribatid mite species were Steganacarus carinatus, Aleurodamaeus setosus, Xenillus tegeocranus, Ceratoppia bipilis, Oribatula tibialis, and Punctoribates punctum. Interestingly, 23 species of oribatid mites were recorded for the first time from the limestone quarry of Saskhori, and one species (Liacarus oribatelloides) was a new record for the Caucasus fauna. The following indices were analyzed: abundance (N), species diversity (S), Shannon’s diversity index (H), and Pielou’s evenness index (J’). Regarding the obtained results, the highest density of oribatid mites was recorded in the habitat with Shibliak shrubbery (332 inds/m2), while the forest habitat was characterized with the highest value for Shannon’s diversity index (2,64). In the publication, we also provide a detailed morphological description of the newly recorded species L. oribatelloides, with the respective illustration, as no figures are given in its original description.

Resumen
AbstractMountain scree habitats are intermediate habitats between the base of the soil and the bedrock. They are composed of a network of small cracks and voids, and are commonly situated at the lower levels of scree slopes. Their environment is defined by empty spaces inside the scree, the absence of light and photoperiod, low temperature, and resource poor conditions. Soil arthropod communities, their trophic structure as well as their use of basal resources in mountain scree are little studied despite the fact that they are important components of these systems. Here, we investigate stable isotope ratios (15N/14N, 13C/12C) of oribatid mites (Oribatida, Acari) to understand their trophic niches and their variation with depth (50 and 75 cm) at two mountain scree sites (Cerdacul Stanciului, Marele Grohotis) in the Romanian Carpathians. Further, we used existing data to investigate the reproductive mode of the species in that habitat, as this may be related to resource availability. We hypothesized that trophic niches of oribatid mites will not differ between the two mountain scree regions but will be affected by depth. We furthermore hypothesized that due to the resource poor conditions oribatid mite species will span a narrow range of trophic levels, and that species are sexual rather than parthenogenetic. Our results showed that (1) oribatid mite trophic structure only slightly differed between the two sites indicating that the trophic ecology of oribatid mites in scree habitats is consistent and predictable, (2) oribatid mite trophic structure did not differ between the two studied soil depths indicating that the structure and availability of resources that were used by oribatid mites in deeper scree habitats varies little with depth, (3) oribatid mite species spanned only three trophic levels indicating that the habitat is rather resource poor, and (4) that all studied oribatid mite species were sexual supporting the view that resource poor conditions favour sexual reproduction.

Resumen
Introduction. The data about mesofauna of the soils of the park areas of Odesa are presented for the first time in this article. Aim. To study the species composition and main ecological characteristics of groups of armored ticks in the soils of the park zones of Odesa city. Methods. In the course of the study, generally accepted methods of soil microarthropod research were used, namely: taking soil samples, extraction of microarthropods in thermoelectrics, and making permanent micropreparations. The main results. According to the results of the study, it was shown that the mesofauna of the soils of the park zones of Odesa contains phonon groups of invertebrates: Enoplea, Malacostraca, Arachnida, Myriapoda, Entognatha, Insecta. Mites (Prostigmata, Mesostigmata, Astigmata) and springtails (Collembola) predominated in all studied biotopes. It is shown that according to the vertical distribution in the soil, mites predominate in the surface layers of the soil (0–5 cm), and springtails prevail in the deeper ones (5–10 cm). 18 species of oribatid mites were identified, which were given the main ecological characteristics: life forms and dominance structure. An environmental assessment was carried out based on the integral index of groups of oribatid mites. Conclusions. According to the analysis of groups of oribatid mites, it is shown that the ecological state of the environment in the parks of the city of Odesa is estimated as “average level of deviations from the norm” in the Shevchenko Park and Youth Square and “slight deviations from the norm” in the Peremogy Arboretum.

Resumen
We investigated the effects of several soil amendment materials, potentially useful for willow biomass crops, on the abundance, diversity, and community structure of free-living soil mites (Acari: Oribatida, Mesostigmata) in a 4-year replicated field experiment. Soil treatments included biosolids (lime-stabilized sewage sludge), chicken manure compost, urea fertilizer, black plastic mulch, and control. The predaceous Mesostigmata (40 spp.) responded differently to soil amendment treatments than did saprophagous and mycophagous Oribatida (28 spp.). The urea fertilizer had no persistent effect on mite assemblages. Plastic mulch did not affect Mesostigmata, but had a lasting detrimental effect on oribatid mites. Mesostigmatid mites benefited from application of biosolids, while Oribatida were most adversely affected by this treatment. When plastic mulch and biosolids were used together, the effect of biosolids predominated. Composted chicken manure supported abundant and diverse populations of both groups.

Resumen
Abstract The features of the structure of the population of oribatid mites (Oribatida) as primary destructors of dead plant material that provide such ecosystem service as improvement of soil fertility are considered. Studies were performed in various stratigraphic types of artifi cial edaphotopes in the reclaimed sites of “Pavlogradskaya” query (Pavlograd, Dnipropetrovsk Region, Ukraine), which were planted with eastern red cedar (Juniperus virginiana Linnaeus). Th e amount of oribatid mite species in the forest litter of studied forest plantation varied from 16 to 25. Minimal number of species (16) and minimal population density of oribatid mites (4720 ind./m2) was established for calcic chernozem topsoil type with sand interlayer, which can be explained by lower thickness of the forest fl oor litter within this reclamation type.

Resumen
AbstractOribatid mites are tiny arthropods that are common in all soils of the world; however, they also occur in microhabitats above the soil such as lichens, mosses, on the bark of trees and in suspended soils. For understanding oribatid mite community structure, it is important to know whether they are dispersal limited. The aim of this study was to investigate the importance of oribatid mite dispersal using Malaise traps to exclude sole passive wind-dispersal. Oribatid mite communities were collected over a 3-year period from five habitat types (coniferous forests, deciduous forests, mixed forests, meadows, bog/heathlands sites) and three seasons (spring, summer, autumn) in Sweden. Mites entered traps either by walking or by phoresy, i.e., by being attached to flying insects. We hypothesized (1) that oribatid mite communities in the traps differ between habitats, indicating habitat-limited dispersal, and (2) that oribatid mite communities differ among seasons suggesting that dispersal varies due to changing environmental conditions such as moisture or resource availability. The majority of the collected species were not typically soil-living species but rather from habitats such as trees, lichens and mosses (e.g., Carabodes labyrinthicus, Cymbaeremaeus cymba, Diapterobates humeralis and Phauloppia lucorum) indicating that walking into the traps or entering them via phoresy are of greater importance for aboveground than for soil-living species. Overall, oribatid mite communities collected in the traps likely originated from the surrounding local habitat suggesting that long distance dispersal of oribatid mites is scarce. Significant differences among seasons indicate higher dispersal during warm and dry periods of the year. Notably, 16 species of oribatid mites collected in our study were sampled for the first time in Sweden. This study also demonstrates that Malaise traps are a meaningful tool to investigate spatial and temporal patterns of oribatid mite communities.

Resumen
The article deals with the results of the study of soil microbiomass and the community of soil inhabiting oribatid mites in the zonal permafrost pale yellow typical soil. It is concluded that the zonal taiga soils of Central Yakutia are characterized by lower values of microbial biomass and higher values of specific metabolic activity of this biomass than the soil of the taiga zone of the European part of Russia. The population of soil inhabiting oribatid mites in these soils is characterized by a large faunal originality, which is significantly different from similar landscapes of neighboring regions. The conducted research allows drawing a conclusion that soil biological methods, and methods of the analysis of a condition and features of functioning of soil microbiomass, number and species diversity of community of soil inhabiting oribatid mites, can be successfully used for ecological monitoring of taiga ecosystems of the Central Yakutia. It is necessary to conduct additional studies to obtain quantitative characteristics of the features of changes in the studied parameters in the taiga ecosystems that experienced different in strength and nature of anthropogenic impacts.

Resumen
Soil mites (Acari) on plantations of chokeberry and black currant under microirrigationBushes of black currant (Ribes nigrum) were slightly higher and wider, and their leaves had a higher content of major nutrients than chokeberry (Aronia melanocarpa). Soil samples were collected in 2004, in spring, summer and autumn, i.e. 3×20 samples from each experimental variant. Three irrigation variants were compared: no irrigation (C), drip irrigation (D), and micro-jet sprinkling (M). In the soil of the black currant plantation, the density of mites was higher (in variants C and D), as compared to the chokeberry plantation. The saprophagous oribatid mites were predominant in the studied mite communities, while Actinedida and Gamasida were less numerous. Oribatid mites were more numerous and more diverse in the black currant plantation than in the chokeberry plantation. The influence of irrigation on the density of oribatid mites was insignificant. In the communities of oribatid mites,Tectocepheus velatuswas distinctly predominant on most plots.

Resumen
Soil contains a diverse fauna and microflora that are vital for maintaining healthy soils and their various ecosystem services. Oribatid mites are typically highly abundant arthropods in the soil and are used as indicators for environmental monitoring. The aim of this study was to determine oribatid mite community response to natural land cover, anthropogenic disturbance, space, and climate in the oil sands region of Alberta, Canada. Our results found that oribatid mite total abundance was significantly reduced by mining, cultivation, and well sites. Species richness was significantly reduced by mining and cultivation. Shannon’s diversity index was significantly higher for all natural land cover types, seismic lines, and forest harvest. Additionally, species diversity was lower under the relative influence of energy-related soft linear disturbances than for naturally vegetated sites and forest harvesting, and was lowered further by anthropogenic disturbances with more impact on soil integrity (cultivation, mines, urban/industrial, road/trail verges, well sites). Abundance, richness, and diversity also increased with increased frost free period and with eastward longitude. Mite community composition included a notable composition difference between lowland habitats and upland forest types, and between natural land cover and intense anthropogenic disturbance types (e.g., mines, cultivation). Our study highlighted oribatid mite communities’ response to natural land cover, anthropogenic disturbance and spatial–climatic factors assessed over broad spatial scales and the potential utility of oribatid mites as ecosystem health indicators under multiple ecological drivers.

Resumen
Frequent convergent evolution in phylogenetically unrelated taxa points to the importance of ecological factors during evolution, whereas convergent evolution in closely related taxa indicates the importance of favourable pre-existing characters (pre-adaptations). We investigated the transitions to arboreal life in oribatid mites (Oribatida, Acari), a group of mostly soil-living arthropods. We evaluated which general force—ecological factors, historical constraints or chance—was dominant in the evolution of arboreal life in oribatid mites. A phylogenetic study of 51 oribatid mite species and four outgroup taxa, using the ribosomal 18S rDNA region, indicates that arboreal life evolved at least 15 times independently. Arboreal oribatid mite species are not randomly distributed in the phylogenetic tree, but are concentrated among strongly sclerotized, sexual and evolutionary younger taxa. They convergently evolved a capitate sensillus, an anemoreceptor that either precludes overstimulation in the exposed bark habitat or functions as a gravity receptor. Sexual reproduction and strong sclerotization were important pre-adaptations for colonizing the bark of trees that facilitated the exploitation of living resources (e.g. lichens) and served as predator defence, respectively. Overall, our results indicate that ecological factors are most important for the observed pattern of convergent evolution of arboreal life in oribatid mites, supporting an adaptationist view of evolution.

Resumen
Knowledge of the oribatid mite community from Patagonian steppe is scarce compared with other environments, such as the Andean-Patagonian forest. In the present research we identified oribatid mites under different environmental conditions: two Patagonian steppe types (grass and shrub), two soil characteristics (bare and covered soil) and two different seasons (autumn and spring). A total of 42 species/morphospecies were found, 13 were new records for Chubut and one was a new record for Argentina. In view of its ecological role in soil formation, it is fundamental that knowledge about this fauna is enhanced in order to provide baselines for study and to aid further understanding about its ecology.

Resumen
Abstract Plant invasions are a serious global threat to biodiversity and ecosystem stability. The invasive giant knotweed Fallopia sachalinensis (synonym: Reynoutria sachalinensis) is one of the most aggressive plant invaders in many countries. It forms dense stands that prevent other species from growing. To assess the impact of the knotweed, oribatid mite communities were studied under Fallopia-free native vegetation and at Fallopia-infested sites (2 types: 90-100% and 30% of coverage) with similar soil. All the sites are located in mixed forest in the Kraków-Częstochowa Upland (Jura Krakowsko-Częstochowska) in south Poland. Species composition and functional group composition of oribatid mite communities were compared. In total, 1540 specimens belonging to 70 oribatid species were collected from 90 soil samples. This successful exotic invasive species had a moderate influence on species richness (20% less species at the totally invaded site than at the Fallopia-free site) and a profound effect on soil oribatid mite community composition. Several oribatid species characteristic of a particular site were observed. Shifts were detected in proportions of groups with different habitat specificity (e.g. higher proportion of eurytopic mites at invaded sites), ecomorphological groups (e.g. lower proportion of litter-dwelling mites at invaded sites), trophic groups (e.g. lower proportion of macrophytophagous mites at invaded sites) and zoogeographical groups (e.g. higher proportion of mites with broad geographical distribution at invaded sites). These observations prove the radical negative change of environmental conditions for soil oribatid mites as a result of Fallopia invasion. The increase in sexually reproducing oribatid mites at invaded sites suggests that this way of reproduction is preferable when resources are in shortage.

Resumen
As a soil-living organism, soil mite presence is important for ensuring the sustainable land. Intensive management practices in forest land drive a change in its community structure. A field study was conducted in Wanagama Education and Research Forest I, Gunungkidul District, Yogyakarta Special Region Province, Indonesia, to assess the role and impact of the different forest management practices on the soil mite community. Soil samples from 15 representative soil sites were taken from the agroforestry, mixed-forest, and pioneer community forest. Collected individuals from August to October 2021 were taken by Berlese-Tullgenn Funnel and identified to morphospecies level. A total of 758 individuals of soil mites were recorded during the study period. Out of these, 21 individuals from agroforestry, 288 individuals from mixed-forest, and 449 individuals from pioneer community forest. Results of the study revealed the occurrence of 3 taxa from 36 morphospecies of oribatid mites occurred in the areas. The Shannon diversity indices of oribatid mites were 1.831, 1.424, and 0.867 in mixed-forest, agroforestry, and pioneer community, respectively. The similarity indices showed there was a similar diversity in agroforestry and mixed-forest, either in pioneer community. Through one-way ANOVA analysis, we stated that differences between of three management practices significantly affected soil mites, especially oribatida rather than prostigmata and mesostigmata.

Resumen
A checklist of the oribatid mite species from two boreal fens in Northern Ontario, Canada is presented. 174 peat soil samples, collected between 2015–2020, yielded a heterogeneous assemblage of 80 species, 57 genera and 33 families. Species richness and diversity were significantly higher in a Sphagnum-dominated fen (69 species) compared to a Carex-dominated fen (51 species), and although 40 species were found at both sites, overall composition was significantly different between the two sites. We also present an update to the seminal work of Behan-Pelletier and Bissett (1994) on Oribatida of Canadian peatlands with 45 new species records for peatlands. Records for the parthenogenetic families Brachychthoniidae Thor, 1934 and Suctobelbidae Jacot, 1938 were considerably expanded, but other families such as Punctoribatidae, Thor, 1937 remain poorly represented in Canadian peatlands. Taken together, species richness estimates range from 86–105 species based on our sampling and the number of undescribed species recorded suggests that the oribatid mite fauna still need further examination to encompass their actual biodiversity in peatlands. We report that the oribatid mite fauna of Canadian peatlands comprise 186 species that includes all published records as of February 2021 and species presented here.

Resumen
AbstractOribatid fauna highly varies among habitats, but different microhabitats within a habitat are also characterized by different mite species. The main goal of the research was to compare the observed structure of an oribatid community when samples were collected at random from the soil-litter layer of 0-10 cm in depth (standard approach) and selectively from 6 types of available microhabitats (complex approach). Samples were taken within a small plot (10 m × 10 m) in a forested area of the Silesian Park (Chorzów, south Poland). Overall, 2642 specimens of Oribatida belonging to 62 species were collected in 66 samples. The structure of the oribatid community observed by means of the 2 sampling approaches was completely different. The abundance and species richness of oribatid mites collected from 6 microhabitats were significantly higher than in the soil-litter layer alone. Results of this study show that random collecting of only soil-litter samples may reduce the evaluation of species richness in a study area by 40%. Each of the studied microhabitats supported a peculiar oribatid fauna.

Resumen
Abstract The study was conducted in the years 2011–2012, in a forest nursery in Białe Błota (Bydgoszcz Forest District). The experiment was established in a 20 m wide belt of trees within a 110 years old stand growing on mixed fresh coniferous forest site. Litter bags containing hardwood and pine wood chips were placed on mineral soil of microplots and covered with a 5 cm layer of litter. The pattern of chips colonization differed between mites belonging to different orders. Predatory Mesostigmata colonized hardwood chips gradually but they were present in high numbers in pine chips from the beginning of the study. Abundance of Actinedida fluctuated within the two-year study cycle. Contrary to that, oribatid mites, which were a predominant mite type, colonized both types of chips gradually, while preferring the pine ones. At the end of the study, the structure of mite communities and mite abundance in pine chips were more similar to forest soil than in hardwood chips. The experiment demonstrated that pine chips provided most oribatid mites with more favorable living conditions than hardwood chips, as they were colonized at a quicker rate and by a greater number of species. The most abundant oribatid mite in both substrates was a eurytopic Tectocepheus velatus that showed no clear preferences towards either of the substrates. Majority of oribatid mites, e.g. Oppiella nova, Metabelba pulverulenta, Oribatula tibialis, Chamobates schuetzi, Galumna lanceata, preferred pine chips. The only species with clear preference for hardwood chips was Eniochthonius minutissimus. A comparison of usefulness of hardwood and pine wood chips in revitalization of degraded soils based on bioindication approach indicated higher suitability of pine chips that are also more available in Polish forests.

Resumen
The present paper gives a review of the taxonomic study on the suborder Oribatida (the cohort Astigmata excepted) in China including Hong Kong and Taiwan, with a checklist of 599 species and subspecies in 275 genera, representing 97 families. One junior synonymes is proposed, i.e., Peloribates praeoccupatus Subías, 2004 is regarded as a junior synonym of Peloribates tsengi Wen, Wang & Chen, 2003. The taxonomic study of oribatid mites in China was started by A. P. Jacot in 1922, and was very productive during the period from 1980 to the end of last century with the efforts of several Chinese and foreign oribatologists. In addition to taxonomic research, publications on biodiversity, seasonal dynamics, biological monitoring for soil pollution, and esterase isoenzyme patterns of oribatid mites have been published by Chinese scholars.

Resumen
Abstract Oribatid mites were investigated on Korčula Island (Croatia) in various microhabitats in an open habitat (moss on rock, moss on soil) and in stone pine forest floor (moss, litter, rotting wood) in late August 2004. Special attention was paid to the age structure of species. These mites were rather abundant but their species diversity was low. The highest density was observed in patches of moss in the forest floor, and the lowest density was in rotting wood. Among the oribatid mites, only several species were abundant (Achipteria nitens, Zygoribatula propinqua, Pilogalumna crassiclava, Scheloribates initialis, S. laevigatus, and Tectocepheus velatus). Some species were rich in juveniles, while in others the adults dominated.

Resumen
The samples of two technogenic sediments (MOS, coal ash sediment; MOD, a mixture of ash and natural soil) and two natural soils (MOM, meadow; MOF—forest; both Cambisol Dystric) in the vicinage of the coal ash basin were studied. We evaluated risk element concentrations and select-ed chemical and microbiological parameters to determine their influence on the community structure of Oribatida. High concentrations of various toxic elements, alkaline pH, and low hu-midity negatively affected the abundance of oribatid mites. The microbial indicator values showed that the soil microbial community formed in technogenic sediments could effectively use organic carbon. However, considering the wide C/N ratio of the substrates, the process of soil organic matter (SOM) decomposition was slowed down, and thus nutrients were less available for the mites, which could be among the reasons why we did not find any individual of oribatid mite in MOS. In MOD, however, we found representatives of three species, but only Tectocepheus velatus sarekensis established an abundant community at the highly contaminated site. Anthropogenic pressure resulted in the selection of r-strategists, which became dominant and reduced the whole community’s species’ diversity. Therefore, we consider it a suitable indicator of improper human intervention in the ecosystem.

Resumen
Abstract The Oribatida (known as moss mites or beetle mites) increase the breakdown of organic material in the soil. The paper analyses the dynamics of their abundance and number of species after various treatments enriching the soil in 4 study areas: afforested post-agricultural area in the Tuchola Forest, afforested degraded post-military training area in Bydgoszcz-Jachcice, and forest nurseries at Białe Błota and Bielawy. The results show that in post-agricultural and degraded soils at the initial stages of forest succession, the density and number of species of oribatid mites were low, even after phyto-land-improvement (afforestation and lupin as green manure). In the forest nurseries, however, we recorded a positive effect of soil revitalizing after mulching with forest ectohumus (i.e. organic surface layer of the soil). The inoculation of soils with forest mesofauna appeared more effective in nursery plantations of silver birch (Betula pendula) and small-leaved lime (Tilia cordata), as compared with Scots pine (Pinus sylvestris). Thus to revitalize degraded soils effectively and to accelerate forest succession, apart from phytoland- improvement, it is advisable also to reintroduce mesofauna, e.g. with the use of forest ectohumus.

Resumen
Abstract Oribatid mites live in the soil or plant matter and usually feed on living and dead plant or fungal material, lichens, carrion, or some species are rarely predatory. Oribatid communities were investigated in litter under pine and cypress trees in selected locations in Sicily: Etna slopes (near Rifugio Sapienza and near Castiglione di Sicily), coastal town Giardini Naxos, Archaeological Museum in Agrigento, and Archaeological Park in Sagesta. The most abundant and diverse oribatid mites lived in cypress litter in Agrigento and on Etna slope. The lowest numbers of individuals and species were recorded in pine litter in Agrigento. In the oribatid mite communities, only 1-3 species were abundant, so the values of Shannon H’ index, and Pielou EPielou and Hurlbert EHurlbert evenness indices were rather low. Their values were the highest in pine litter near Rifugio Sapienza, located nearest to the crater of Etna, while the lowest in pine litter in Agrigento. The former habitat was rich in oribatid mites and species, with a large participation of small species, like Suctobelbella subcornigera, Brachychthonius impressus, and Liochthonius simplex, which made up nearly 63% of the total number of oribatid mites within that habitat. In other habitats, usually Oribatula propinqua dominated, but in pine and cypress litter in Giardini Naxos, Oppiella nova and Ramusella clavipectinata were the most abundant, respectively. Among oribatid mites, adults usually dominated, but Adrodamaeus femoratus, Aphelacarus acarinus, Brachychthonius impressus, Liochthonius simplex, Cosmochthonius reticulatus, Metabelba pulverulenta and Pilogalumna crassiclava were rich in juveniles.

Resumen
Forest sites in Northwestern Argentinean Patagonia were surveyed to determine the oribatid mite fauna. A taxonomic inventory of oribatid mites was carried out in Northwestern Argentinean Patagonia to establish the taxonomic diversity, for increasing the knowledge of their distribution, detecting new species and assessing environmental effects on the oribatid mite community. Eleven sampling sites in nearly pure forests of Austrocedrus chilensis, Nothofagus dombeyi, Nothofagus antarctica were selected as these are among the most recurrent arboreal species found in this region. Samples of leaf litter, soil and pitfall traps contents were taken from each forest. Fifty-five oribatid species, belonging to 46 genera in 28 families, were found. Nine species are new records for Argentina and one for continental Argentina. Thirty-two species were recorded in A. chilensis forests, 35 in N. dombeyi forests and 20 in N. antarctica forests. Fifty species were found in leaf litter, 35 in soil and eight in pitfall traps. Fourteen species were recorded exclusively in leaf litter, one in soil and four in pitfall traps. A high level of endemism is confirmed as nearly 62 % of collected species have previously been found only in Southern Andes supporting the existence of an associated autochthonous oribatid fauna.

Resumen
In this study the oribatid mite communities of conventional and organic vineyards in theValencian Community (Spain) were compared. The soil samples were collected in El Poble Nou de Benitatxell in autumn 2014 and spring 2015 from four sites, treated as replicates, each including a conventional vineyard, an organic vineyard, and a control (natural habitat, i.e. in plots 1-3 an abandoned vineyard, in plot 4 an area never used in agriculture). Two parallel samples were collected in each vineyard from a zone between vine rows, driven by a tractor (Tr), a zone between vines (Vi), the border of the vineyard (Bo) and from a control, making a total of 112 samples. In total 3,225 oribatid mites were obtained represented by 59 species. No differences were found in density of Oribatida between the conventional, organic vineyards and the control, but the species diversity was higher in the control than in the vineyards. In the vineyards the density and species number of the oribatid mites were highest between vines (the average from all vineyards and both seasons was 4,400 individuals per 1 m2, 15 species), followed by the border of the vineyards (2,800 individuals per 1 m2, 14 species) and were lowest between vine rows (400 individuals per 1 m2, 6 species). The species diversity of Oribatida was higher in autumn than in spring, while the density followed this pattern only in the vineyards, but not in the control. In the vineyards Oribatula excavata dominated (D = 25), followed by Minunthozetes quadriareatus and Passalozetes africanus (D = 18 and 14, respectively), while in the control these species were not abundant. In the control the most abundant species was Oppiella subpectinata (D = 28), followed by Eremulus flagellifer (D = 20). Podoribates longipes and Steganacarus boulfekhari are reported for the first time in Spain. To conclude, the oribatid mites did not benefit from the organic cultivation of the vineyards, probably because they are tolerant to herbicides used in the conventional systems but sensitive to mechanical cultivation of soil, which was even more intense in organic vineyards than in the conventional ones.
