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...

The association between the ectoparasitic mite, Erythraeus Latreille (Acari: Prostigmata: Parasitengona) and psyllid Russelliana adunca Burckhardt (Hemiptera: Psylloidea) is reported for first time. Larval erythraeid mites are not common on psyllids, therefore this report adds a new host widens distribution of mite in South America.

in the course of a faunistic survey of water mites in guilan province in 2006, the second iranian species of aquatic oribatid mites was collected and identified as hydrozetes thienemanni strenzke (acari: oribatida: hydrozetidae).

Acari harbor numerous minute species of agricultural economic importance, mainly Tetranychidae and Phytoseiidae. Great efforts have been established by means recovering morphological, molecular, phylogenetic traits for identification. Traditional identification still relies on external diagnostic characters, which are limited usually exhibit large phenotypic plasticity within the species, rende...

Spiders are one of the eleven orders of the class Arachnida, which also includes groups such as harvestmen (Opiliones), ticks and mites (Acari), scorpions (Scorpiones), false scorpions (Pseudoscorpiones), windscorpions (Solifugae), and vinegaroons (Uropygi). All arachnid orders occur in North America. Arachnida today comprises approximately 640 families, 9000 genera, and 93,000 described specie...

during 2009, in the course of a faunistic survey of terrestrial parasitengona mites in jahrom region, ronaldothrombium bellator (southcott, 1986) (acari, trombidiidae) was collected and identified for the first time from iran. it was collected as ectoparasite of an unidentified araneae, which is a new host for r. bellator.
