A plea for DNA taxonomy
TLDR
This work proposes a scheme in which DNA would be the scaffold of a taxonomic reference system, whilst maintaining the importance of the morphological information associated with whole specimens. Expand
Appendage development in embryos of the oribatid mite Archegozetes longisetosus (Acari, Oribatei, Trhypochthoniidae)
TLDR
Claparede’s organs, present between coxae of legs I and II of larvae, are shown for the first time unequivocally to derive from the base of legs II, and are proposed to be homologous to the lateral organs of other arachnid groups. Expand
DNA points the way ahead in taxonomy
TLDR
It is time for DNA's unique contribution to take a central role in assessing new approaches and to be considered in the development of new medicines and vaccines. Expand
Of mites and zen: expression studies in a chelicerate arthropod confirm zen is a divergent Hox gene
TLDR
Cloned, from an oribatid mite, a gene homologous to the zerknült (zen) genes of insects and the Hox 3 genes of vertebrates, and it is proposed that the zen genes have lost their Hox-like function in the ancestor of the insects. Expand
Molecular systematics of Acarus siro s. lat., a complex of stored food pests.
TLDR
This pilot study investigated whether genetic data supported the separate species status of these forms and suggested that a congener, Acarus gracilis, is basal to the A. siro species complex. Expand
The delineation of the fourth walking leg segment is temporally linked to posterior segmentation in the mite Archegozetes longisetosus (Acari: Oribatida, Trhypochthoniidae)
TLDR
The development of segmentation in the oribatid mite Archegozetes longisetosus is followed using time‐lapse and scanning electron microscopy, as well as in situ hybridizations of the A. longisettosus orthologues of the segmentation genes engrailed and hedgehog. Expand
DNA phylogeny of the extinct marsupial wolf
TLDR
The genetic data suggest that the Marsupial wolf was more closely related to other Australian marsupial carnivores than to those of South America, and represents an example of convergent morphological evolution to South American car-nivorous marsupials as well as to true wolves. Expand
Problems of reproducibility – does geologically ancient DNA survive in amber–preserved insects?
TLDR
Attempts to reproduce DNA sequences from amber– and copal–preserved bees and flies have failed to detect any authentic ancient insect DNA, suggesting that DNA does not survive over millions of years even in amber, the most promising of fossil environments. Expand
Radiation in sexual and parthenogenetic oribatid mites (Oribatida, Acari) as indicated by genetic divergence of closely related species
TLDR
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
