Abstract

Oribatid mites, being highly sensitive to changes in habitat conditions, are a promising bioindicator for assessing the state of ecosystems. This article presents the results of an analysis of all available data (2015–2023) on the diversity and biotopic distribution of oribatid mites in the Lapland Nature Reserve, including material from the Great Scientific Expedition organized with the support of PJSC MMC Norilsk Nickel (Nornickel). The generalized taxonomic list of Oribatida of the Lapland Nature Reserve includes 94 species/subspecies from 55 genera and 31 families, of which 17 species have been recorded in this area and Protoribotritia oligotricha Märkel, 1963 on the Kola Peninsula for the first time. The greatest diversity has been recorded for the families Brachychthoniidae (21 species), Suctobelbidae (13), Oppiidae (9), Carabodidae (6), and Crotoniidae and Ceratozetidae (each including 5 species). The oribatid mite communities form three clusters: forest (pine forests and dwarf shrub tundra), tundra (lichen tundras), and bog (cotton-grass sphagnum bog). The oribatid mite communities of the forest group have the highest similarity of their faunas (35–42%). The lowest similarity of species composition with other oribatid communities has been recorded for sphagnum bog (8–12%). In addition to the abundance and parameters of oribatid alpha-diversity, one should focus on the dominance structure and abundance of eurytopic species (Oppiella nova (Oudemans, 1902) and Tectocepheus velatus (Michael, 1880)) during monitoring, which may serve as additional indicators of habitat change. The results are an important step in establishing the basis and formation of long-term data series that will make it possible to monitor the state of the areas of the Lapland Nature Reserve and identify and track trends.
