Total density and spectrum of taxocene families of oribatid mites (Acari, Oribatida) on the
Yavoriv NNP
The article provides information on the family structure of oribatid mites of the Yavoriv National
Nature Park. The following five habitats within eight localities were studied. Namely: on the outskirts
of the village of Lelekhivka: pine forests, oak-beech forest, mixed forests, swamp (bottom of a dried-up
reservoir); on the outskirts of the village of Vereshchytsia, a mixed forest and an alder-hornbeam shrub
on a moist substrate in a pine forest were investigated. Representatives of oribatids belonging to 31
families were found for the studied territory, which is 69% of the families noted for the entire territory
of the Ukrainian Roztocze. These include Achipteriidae, Autognetidae, Brachychthoniidae,
Carabodidae, Ceratoppiidae, Ceratozetidae, Chamobatidae, Crotoniidae, Damaeidae, Eremaeidae,
Euphthiracaridae, Galumnidae, Hermanniellidae, Hypochthoniidae, Liacaridae, Malaconothridae,
Nanhermanniidae, Nothridae, Oppiidae, Oribatellidae, Oribatulidae, Parakalummidae,
Phenopelopidae, Phthiracaridae, Punctoribatidae, Scheloribatidae, Suctobelbidae, Tectocepheidae,
Tenuialidae, Xenillidae, Zetorchestidae. Among the studied habitats, the richest in terms of the number
of detected families are mixed forests, represented by 20 taxa. The total density of oribatids in mixed
forests was 21.7 thousand specimens per m . Representatives of 16 families of oribatid mites were found
2
in pine forests, an total density of 26.1 thousand specimens per m . Alder and hornbeam scrub on a
2
moist substrate in a pine forest includes oribatids from 18 families and the density in the studied biotope
2
reaches as much as 50.7 thousand specimens per m . For the oak-beech forest, representatives of only
10 families of oribatids were found, the total density of which was 12.9 thousand specimens per m .
2
For the bog (the bottom of a dried-up reservoir), representatives of oribatids of only one family were
2
found - Ceratozetidae, the total density was only 1.1 thousand specimens per m . The established
structure of family gives rise to further studies of oribatids of the Yavoriv National Nature Park for
their species inventory.
Keywords: oribatid mites, families, Roztocze, mixed forest, pine forest, oak-beech forest.
