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.

“…Generally, fungal feeders dominated among oribatid mites suggesting that the most important food resource for oribatid mites on the bark of dead wood are fungi. The results further suggest that fungal feeding species separate into those relying on basidiomycete fungi, e.g., C. femoralis, C. areolatus, C. coriaceus, L. coracinus and Cepheus dentatus, typically occurring in sporocarps of basidiomycetes (Maraun et al, 2014) and from those predominantly feeding on ascomycete fungi, e.g., C. borealis, Eupelops hirtus and Oribatella calcarata, dominating in the litter layer of forests (Visser and Parkinson, 1975;Shanthi and Vittal, 2010).…”

“…Most oribatid mite species are fungal feeders (see below), and Schneider and Maraun (2005) demonstrated that preferences of oribatid mite species for fungal species as food differ. Additionally, juveniles of the genus Carabodes are associated with basidiomycete fungi growing on dead wood (Maraun et al, 2014;Hågvar and Steen, 2013). This suggests that fungal species consumed by species such as L. humerata are more abundant on beech logs whereas fungal species that are used by Carabodes species, especially Basidiomycetes, are more abundant on oak logs.…”

“…Especially basidiomycete fungi benefit from the accumulation of dead wood as they are the most important wood decomposers able to break down recalcitrant wood compounds including lignin. A large number of animal species benefit from the presence of fungi by feeding on fungal hyphae or sporocarps or using fungal sporocarps as habitat (Matthewman and Pielou, 1971;Maraun et al, 2014).…”

“…However, there are other records documenting individuals of this species collected from bark samples of a beech grove in Massane (Travé, 1978) or from Fomitopsis pinicola (Fr.) Karst., a mushroom which colonizes all kind of trees beginning from living to dying or dead ones, in Germany (Maraun, Müller, Bässler, & Scheu, 2014; Weigmann, 2014). Moreover, Murvanidze, Mumladze, Arabuli, Barjadze, and Salakaia (2016) obtained their specimens from dead wood in Georgia and all but one population of the present study were found in bark samples of P. abies trees, which were infested by different bark beetle species.…”

Species diversity is generally higher in the tropics compared to the temperate zones. The phenomenon that one species of an almost exclusively tropical living genus was able to adapt successfully to the cold northern regions is rather rare. However, the oribatid mite Dolicheremaeus dorni represents such a species and is in the focus of this study. While 180 Dolicheremaeus species are confined to the tropics and subtropics, only five species are known to occur in temperate climates and D. dorni represents the only species with a wider distribution in this climatic region. This species is distributed in Central and Southern Europe and was now recorded for the first time in Austria. A morphological and molecular genetic investigation of specimens from Austria, Poland and Croatia confirmed this distribution pattern and revealed specific geographic clades and haplotypes for each population and hence indicate low gene flow between populations. A further molecular genetic analysis of the 18S rRNA gene sequence of D. dorni confirmed its phylogenetic position within Carabodoidea. Based on record information, this species is associated with trees or tree habitats and seems to be rather a generalist than a specialist for a specific substrate (e.g., tree species) or food source.
