We investigated the within-site distribution of Enchytraeidae, Collembola, Oribatida, Mesostigmata and Prostigmata relative to varying water level and substrate quality on pine mire sites forming a drainage succession continuum. Collembolans were most intolerant of wetness, favoring drier locations at all stages of the drainage succession. In general, the effect of water level variation on the ...

Chelonacarus elongatus n. gen., n. sp. is proposed for a cheyletoid mite (Acari: Prostigmata) of the family Cloacaridae found in the cloacal tissue of the endangered green turtle Chelonia mydas Linnaeus, 1758 from the Atlantic coast of the Republic of Panama. In females, the new genus is distinguished from other genera of turtle cloacarids by the elongate slender shape of the idiosoma, the shap...

Belowground biodiversity loss from anthropogenic causes is far less addressed and quantified than aboveground loss. Soil fauna supports soil productivity biogeochemical cycles, their decline needs further research. We tested the effects of a woodland harvest gradient (0, 30, 50, 70% biomass removal) on litterfall, mesofauna density, Oribatida diversity in three sites northwestern Patagonia (Arg...

We examined mitochondrial DNA (COI) variability and distribution of Stereotydeus spp. in Victoria Land and the Transantarctic Mountains, and constructed Neighbour Joining (NJ) and Maximum Likelihood (ML) phylogenetic trees using all publicly available COI sequences for the three Stereotydeus species present (S. belli, S. mollis and S. shoupi). We also included new COI sequences from Miers, Mars...
