Imaging applications of synchrotron X‐ray phase‐contrast microtomography in biological morphology and biomaterials science. I. General aspects of the technique and its advantages in the analysis of…
It is concluded that synchrotron radiation microtomography has a great potential in biological microanatomy.
Mitochondrial COII sequences indicate that the parthenogenetic earthworm Octolasion tyrtaeum (Savigny 1826) constitutes of two lineages differing in body size and genotype
High genetic divergences indicate ancient separation of parthenogenetic lineages of the oribatid mite Platynothrus peltifer (Acari, Oribatida)

It is concluded that P. peltifer, as it is currently conceived, has existed for perhaps 100 million years, has an extant distribution that results from continental drift rather than dispersal and was subject to several cryptic speciations.
Speciation in the parthenogenetic oribatid mite genus Tectocepheus (Acari, Oribatida) as indicated by molecular phylogeny
An automated device for the digitization and 3D modelling of insects, combining extended-depth-of-field and all-side multi-view imaging
Abstract Digitization of natural history collections is a major challenge in archiving biodiversity. In recent years, several approaches have emerged, allowing either automated digitization, extended…
Integrative taxonomy: Combining morphological, molecular and chemical data for species delineation in the parthenogenetic Trhypochthonius tectorum complex (Acari, Oribatida, Trhypochthoniidae)
The approach combined morphological, molecular and chemical data to investigate diversity and species delineation in a parthenogenetic oribatid mite species complex and may help to build up more stable phylogenetic hypotheses in the future.

The hypothesis that some of the parthenogenetic oribatid mite taxa (Tectocepheus, Nothrus) are ‘ancient asexuals’ is supported and the existence of a meiotic process is inferred, which is consistent with the automixy known from several other parthenagenetic o ribatid species.
Karyology and sex determination of oribatid mites
The first data on the karyotype of Archegozetes longisetosus Aoki (Trhypochthoniidae) is presented, and the conclusions of ZHANG et al. cannot represent the general state of cytogenetics in Oribatida.
Molecular phylogeny of oribatid mites (Oribatida, Acari): evidence for multiple radiations of parthenogenetic lineages
Results from neighbour joining (NJ) and maximum parsimony (MP) algorithms indicate that several species rich parthenogenetic groups like Camisiidae, Nanhermanniidae and Malaconothridae are monophyletic, consistent with the hypothesis that some oribatid mite groups diversified despite being parthenogenic.
Specialization of oribatid mites to forest microhabitats—the enigmatic role of litter
This work uses interaction networks between microhabitats and their inhabitants to resolve and quantify the community structure (species composition, richness, and diversity) of oribatid mites (Oribatida) in five discrete, patchy substrates—dead wood, lichens, mosses, sod, and tree bark—and in the general leaf litter.
