Evolutionary Aspects of Oribatid Mite Life Histories and Consequences for the Origin of the Astigmata
With densities of several hundred thousand individuals per square meter, oribatid mites are often the most diverse and numerically dominant arthropods in organic layers of temperate forest soils,Expand

A century ago, Antonio Berlese first discussed the close phylogenetic relationship between the large mite groups Oribatida and Astigmata. Since then, information having phylogenetic value has greatlyExpand

Trophic niche differentiation in soil microarthropods (Oribatida, Acari): evidence from stable isotope ratios (15N/14N)
Abstract The large number of animals that coexist in soil without any clear niche differentiation has puzzled biologists for a long time. We investigated stable isotope ratios (15N/14N) in a diverseExpand

Oribatid mites as a major dietary source for alkaloids in poison frogs
Alkaloids in the skin glands of poison frogs serve as a chemical defense against predation, and almost all of these alkaloids appear to be sequestered from dietary arthropods. CertainExpand

Catalogue and historical overview of juvenile instars of oribatid mites (Acari: Oribatida).
Oribatid mites (Acari: Oribatida) comprise a taxonomically and morphologically diverse suborder of about 10,000 described species, not including the hyporder Astigmata, with collectively a globalExpand

High genetic divergences indicate ancient separation of parthenogenetic lineages of the oribatid mite Platynothrus peltifer (Acari, Oribatida)
Theories on the evolution and maintenance of sex are challenged by the existence of ancient parthenogenetic lineages such as bdelloid rotifers and darwinulid ostracods. It has been proposed thatExpand

Opisthonotal gland chemistry of early-derivative oribatid mites (Acari) and its relevance to systematic relationships of Astigmata
Abstract Mites of the suborder Astigmata produce a variety of chemicals – monoterpenes, aromatics and straight-chain hydrocarbons - in a pair of exocrine opisthonotal glands. The more commonExpand

The distribution, mechanisms and evolutionary significance of parthenogenesis in oribatid mites
Highly derived oribatid mites (Brachypylina) seem to fit most predictions of evolutionary theory regarding the ecological, geographical and taxonomic distribution of parthenogenesis. EarlierExpand
