Oribatid Mites in the Glacier Foreland at Hardangerjøkulen
نویسندگان
چکیده
The Oribatida on 3 moraines (from 1955, 1934 and 1750) near the outlet Midtdalsbreen of Hardangerjøkulen glacier (Norway) were investigated. The highest density of mites was observed on the moraine exposed in 1934 (67 years after the glaciers retreat), while the highest number of species (14) was noted on the oldest moraine (206 years after the glaciers retreat). Two species, Tectocepheus velatus and Liochthonius lapponicus, were present in all sites. Tectocepheus velatus was relatively abundant on all moraines, while the density of L. lapponicus decreased with moraine age. The population of Camisia horrida (Hermann, 1804), exhibited variability in the occurrence of notogastral setae f 1 . This confirmed that C. borealis Thorell, 1871, with setae f 1 in the adult, is a junior synonym of C. horrida.

Oribatid mites (Acari, Oribatida) of plain area of the Southern European Russia.
The paper is devoted to the fauna of oribatid mites (Acari: Oribatida) mostly of a plain area of the Southern European Russia. The most updated taxonomic list of oribatid mite taxa compiled from the original authors' data collected after sam- pling soil, nests and plumage of birds, as well as published sources is presented. It includes 256 species of oribatid mites belonging to 72 families. Twe...

The fauna and community structure of oribatid mites (Acari: Oribatida) in the Pskov Region of Russia is not yet comprehensively studied. Until now not much attention has been paid to soil communities of bogs and open landscapes of this area. The aim of this study was to compare the community composition of oribatid mites in different habitats in the environs of the Polistovsky National Nature R...
متن کاملApplication of Soil Oribatid Mites as Bioindicators in Impact Areas of the Gas Industry in the West Siberian Tundra
Atmospheric emissions from gas pre-treatment centers of the Gazprom Dobycha Yamburg LLC influenced the community of oribatid mites in southern tundra ecosystems. It was evidenced by changing the ratio of the ecological groups of the oribatid mites rather than its total abundance. The euedaphic oribatid mites prevailed essentially in the mites community of more contaminated biotopes located clos...
متن کاملMultiple convergent evolution of arboreal life in oribatid mites indicates the primacy of ecology.
Frequent convergent evolution in phylogenetically unrelated taxa points to the importance of ecological factors during evolution, whereas convergent evolution in closely related taxa indicates the importance of favourable pre-existing characters (pre-adaptations). We investigated the transitions to arboreal life in oribatid mites (Oribatida, Acari), a group of mostly soil-living arthropods. We ...
