Active dispersal of oribatid mites into young soils
Active dispersal is an important dispersal mechanism in the colonization of young soils, however, several species combine different dispersal mechanisms, so that the number of possible dispersal pathways is one factor that determines specimen- and species-richness in a newly found habitat.
Small-scale spatial heterogeneity of stable isotopes signatures (δ15N, δ13C) in Sphagnum sp. transfers to all trophic levels in oribatid mites
Investigation of the heterogeneity within and between three Sphagnum microhabitats and the heterogeneity of potential consumers in two German peatlands using stable isotopes found small-scale heterogeneity of the potential food resource (Sphagnum sp.) in 15 N and 13 C was high.
Parthenogenetic vs. sexual reproduction in oribatid mite communities
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.

This is the first study to demonstrate successful passive dispersal with running water for two groups of terrestrial soil microarthropods, including subsequent colonisation of new soil.
The oribatid mite community of a German peatland in 1987 and 2012 - effects of anthropogenic desiccation and afforestation
- Ricarda Lehmitz
A comparison of the oribatid mite assemblages recorded in 1987 and 2012 from a Sphagnum bog being part of a large peatland complex that has suffered from drainage between the two periods indicates that desiccation in Sphagnu sp.
Wind dispersal of oribatid mites as a mode of migration
It was demonstrated that mainly arboreal oribatid species were dispersed by wind – even at 160 m height – and can therefore be spread over large distances and suggested that immigration into young soils most likely occurs by repeated short-distance dispersal.
Bioindication in peatlands by means of multi-taxa indicators (Oribatida, Araneae, Carabidae, Vegetation)
Abstract Peatlands host a large number of highly specialised species and are important carbon storage and freshwater reservoirs, but are heavily threatened by, e.g., peat extraction and drainage. For…
Convergent evolution of aquatic life by sexual and parthenogenetic oribatid mites

The results indicate that aquatic life in oribatid mites evolved at least 3×: once in Limnozetoidea (including only freshwater taxa) and at least twice in Ameronothroidea, suggesting that parthenogenetic reproduction is not selected for by disturbances but by unlimited access to resources.
The nuclear 28S gene fragment D3 as species marker in oribatid mites (Acari, Oribatida) from German peatlands
This study emphasises that 28S D3 rDNA is a useful barcode for the identification of oribatid mite specimens and represents an important step in building-up a comprehensive barcode library to allow metabarcoding analyses of environmental peatland samples for Oribatida in Germany as well as in Central Europe.
