“…The aquatic species Hydrozetes parisiensis Grandjean, 1948 was found on the swampy shore of Nabada Lake (unpublished data), but in small numbers and it was absent from the fauna in our later research (Murvanidze & Kavavadze, 2010). In the current study, P. peltifer and P. manzanoensis were recorded in lower densities compared to the earlier study (Murvanidze & Kvavadze, 2010) and N. pratensis was not detected. The difference between the results of this and the previous study may be due to the corresponding sampling periods.…”

“…In the early study of oribatid mites of Kolkheti National Park (Murvanidze & Kavavadze, 2007, 2010, the dominant species of the Juncus bog ecosystems of Kolkheti Lowland were Z. furcatus, N. nana, P. peltifer, Nothrus pratensis Sellnick, 1929 and P. manzanoensis.…”

“…The presence of boxwood at this altitude (H= 0-5m) was considered a surprising finding from a biogeographical point of view (Arabuli et al, 2007). In 2005, an inventory of oribatid mites of Kolkheti Lowland was done, resulting in the finding of 47 species from Juncus bog ecosystems, with Punctoribates manzanoensis Hammer, 1958 and Zetomimus furcatus (Pearce & Warburton, 1906) as new reports for Caucasian fauna, and 79 species for flood-plain alder forests , 2010 The present work is part of a large spatial scale investigation of the invertebrate fauna of Kolkheti National Park, covering an area of 28,571 ha. The objective of this research is to evaluate the diversity of invertebrates in the park, determining unique, rare, endemic, or threatened species as the distribution patterns of oribatid mites in main habitats and ecosystems.…”

“…The boundaries between terrestrial and aquatic ecosystems are critical transition zones and generally support unique or diverse biota (Bardgett et al, 2001). Aquatic and semi-aquatic habitats of Kolkheti National Park create a refuge for many rare and endemic plant and animal species, including invertebrates (Arabuli et al, 2007;Denk et al, 2001;Kikodze & Gokhelashvili, 2007;Kikvidze & Ohsawa, 2001;Murvanidze & Kvavadze, 2010;Zazanashvili, 2009). The flooded habitats of these territories are necessary for migratory, wintering and nesting bird species (Kikodze & Gokhelashvili, 2007;Zazanashvili, 2009).…”

The key subject of this investigation was to study distribution patterns of oribatid mites in the main habitats and ecosystems of Kolkheti National Park. Oribatida were studied in 1) sand dunes, 2) Juncus bogs, 3) flooded alder (Alnus barbata C. A. Mey) forests, and 4) humid alder forests. Sampling was conducted in November 2009 at 18 sites along three transects. For exploratory analysis, we applied clustering techniques. Correlation between species number, density and humus was calculated. Chao1 statistics were used to estimate the completeness of sampling. Forty six oribatid species were recorded. The highest Shannon diversity index was registered for alder forests, whereas the lowest index was observed for dunes. In sand dunes 16 species were found, three of which occurred only in this landscape. In Juncus bogs, 32 species were recorded, and 16 were unique to this landscape, including bog specific Zetomimus furcatus (Warburton & Pearce, 1905), Euzetes globulus (Nicolet, 1855) and Punctoribates manzanoensis Hammer, 1958. Twenty two species were found in flooded forests, seven being exclusive. Ten species were recorded in humid forests, and Metabelbella macerochaeta Bulanova-Zachvatkina, 1965 and Eremobelba geographica Berlese, 1908, typical inhabitants of humid forest soils, appeared as exclusive species. Faunal comparisons among landscapes show high similarity between dune and bog oribatid mite communities, followed by flooded and humid alder forests. In dunes and bogs, total faunal density is determined by euryecological species, whereas in alder forests density was determined by high abundance of humid and extremely humid specific species.

“…Adult oribatid mites have a hard, resistant cuticle that is well preserved in mire peat and in most terrestrial and lake sediments (Solhøy & Solhøy ; Solhøy ). They are also one of the most diverse and numerous invertebrate groups in peatlands (Behan‐Pelletier & Bissett ; Murvanidze & Kvavadze ).…”

Permafrost dynamics play an important role in the surface hydrology and carbon balance of northern peatlands. Plant macrofossil analysis with radiocarbon dating has been widely used in detecting past permafrost dynamics in peatlands; however, there is a lack of permafrost‐specific plant indicator species, which makes it challenging to determine the exact timing of historical permafrost aggradation. We investigated the indicator value of oribatid mites in determining past permafrost dynamics in sub‐Arctic peatlands. Analyses of subfossil oribatid mite assemblages of Holocene peat profiles from two mires, one in northern Finland and one in northeastern European Russia, were carried out and interpreted using modern calibration data from the same study areas. The results were compared with previously published reconstructions of permafrost history based on plant macrofossil analyses from the same locations. The results suggest that the oribatid mites Carabodes labyrinthicus, Chamobates borealis and Neoribates aurantiacus are promising indicator species to detect past permafrost occurrence in peatlands. In addition, N. aurantiacus is clearly associated with the presence of lichens, which is particularly useful because lichen remains are rarely preserved in peat deposits. Results are in accordance with earlier studies showing that oribatid mites are useful indicators of past environmental change.

Parthenogenetic vs. sexual reproduction in oribatid mite communities

The dominance of sex in Metazoa is enigmatic. Sexual species allocate resources to the production of males, while potentially facing negative effects such as the loss of well‐adapted genotypes due to recombination, and exposure to diseases and predators during mating. Two major hypotheses have been put forward to explain the advantages of parthenogenetic versus sexual reproduction in animals, that is, the Red Queen hypothesis and the Tangled Bank/Structured Resource Theory of Sex. The Red Queen hypothesis assumes that antagonistic predator—prey/ parasite–host interactions favor sex. The Structured Resource Theory of Sex predicts sexual reproduction to be favored if resources are in short supply and aggregated in space. In soil, a remarkable number of invertebrates reproduce by parthenogenesis, and this pattern is most pronounced in oribatid mites (Oribatida, Acari). Oribatid mites are abundant in virtually any soil across very different habitats, and include many sexual and parthenogenetic (thelytokous) species. Thereby, they represent an ideal model group to investigate the role of sexual versus parthenogenetic reproduction across different ecosystems and habitats. Here, we compiled data on oribatid mite communities from different ecosystems and habitats across biomes, including tropical rainforests, temperate forests, grasslands, arable fields, salt marshes, bogs, caves, and deadwood. Based on the compiled dataset, we analyzed if the percentage of parthenogenetic species and the percentage of individuals of parthenogenetic species are related to total oribatid mite density, species number, and other potential driving factors of the reproductive mode including altitude and latitude. We then interpret the results in support of either the Red Queen hypothesis or the Structured Resource Theory of Sex. Overall, the data showed that low density of oribatid mites due to harsh environmental conditions is associated with high frequency of parthenogenesis supporting predictions of the Structured Resource Theory of Sex rather than the Red Queen hypothesis.
