Systematic revision of the genus
The genus Maudheimia Dalenius, 1958 occurs on the Antarctic continent and contains four known species (M. wilsoni Dalenius, 1958; M. petronia Wallwork, 1962; M. marshalli Coetzee, 1997 and M.Expand
Speciation in the parthenogenetic oribatid mite genus Tectocepheus (Acari, Oribatida) as indicated by molecular phylogeny
The results suggest that the different morphotypes of Tectocepheus indeed evolved in the absence of sexual reproduction, and that TectOcepheus minor, Tectavelatus velatus and Tectecepheus sarekensis are best considered distinct species and that 18S rDNA, hsp82 and ef-1α are powerful markers for resolving phylogenetic relationships of oribatid mites.

Radiation in sexual and parthenogenetic oribatid mites (Oribatida, Acari) as indicated by genetic divergence of closely related species
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. Expand
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. Expand
Oribatid mites (Acari: Oribatida) from the coastal region of Portugal. III. New species of Scutoverticidae and Scheloribatidae.
Three new species of Oribatida were found from soils of different coastal habitats in South Portugal. Scutovertex mikoi sp. nov. (Scutoverticidae) is the smallest European species of the genus,Expand
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.

Acari: Limnic Oribatida
In Europe (excluding Caucasus and Macaronesian Islands) SCHATZ (2005) calculates in total about 2100 species of described oribatid mite species, worldwide about 10.000 species. In Germany about 520Expand
Order Acari - General introduction and key to the major groups
The ancestral arachnid tagmata, the prosoma and the opisthosoma, not apparent as main body divisions, but body secondarily divided into gnathosoma bearing as appendages the chelicerae and palps. Expand
Interactions between isopods and collembolans modulate the mobilization and transport of nutrients from urban soils
The effects of soil animals belonging to different functional groups on the turnover of organic matter in urban ecosystems is characterized and the investigated urban soil was less “leaky” in these treatments, since carbon leaching was uncoupled from nutrient mobilization and attenuated in the presence of isopods and Collembola.
