“…6). As all these species are rheobionts (Böttger and Martin 1995;van der Hammen and Smit 1996;Di Sabatino et al 2010), it is unsurprising that rapid water flow is a deciding factor influencing their distribution. All these species were caught in the highest numbers in the mesohabitats at site K10 (K10/1-2), with well-developed lotic zones, but they were also numerous at mesohabitats K11/1-2, K13/1 and K13/4 (Online Resources 1 and 2 in the ESM).…”

The influence of environmental factors on water mite assemblages (Acari, Hydrachnidia) in a small lowland river: an analysis at different levels of organization of the environment

Research on the ecology of water mites in flowing water has focused mainly on analysis of factors directly affecting these organisms in the aquatic environment. The hypothesis of this study was that apart from factors acting within the aquatic environment, the formation of Hydrachnidia communities in lotic ecosystems may also be affected by factors acting in the terrestrial environment. The analysis was made at three different levels of organization of the environment: (1) landscape level (subcatchments, terrestrial environment), (2) macrohabitat level (sampling sites, aquatic environment) and (3) mesohabitat level (sampling sub-sites, aquatic environment). Some correlation was noted between certain species and some sub-catchment parameters. This may indicate a link between some landscape features (terrestrial environment) and the formation of water mite assemblages in the river. The low percentage for physicochemical parameters together in explaining the variance in occurrence of species, very low correlations between species and physicochemical parameters and the discrepancy in the grouping of sites in the case of faunal data and data on the physicochemical indicates that physicochemical factors had little influence on water mites. Taking into account all three levels of organization of the environment analyzed, we can say that at the landscape level we can find only indirect relationships between environmental factors and the fauna inhabiting the aquatic environment; at the macrohabitat level the description of Hydrachnidia is more precise but still of a general nature. Only analysis at the mesohabitat level fully explains the specific character of Hydrachnidia assemblages.

“…Among the water mites found, a very rare species was observed-Lebertia oblonga, which is known from several records from Europe (Gerecke 2009;Di Sabatino et al 2010). In Russia, this species has previously been recorded only in Lake Ladoga (Sokolow and Yankovskaya 1962).…”

In this work, we present the data pertaining to the fauna and ecology of water mites found in the water bodies of the Bolshoy Yugan River Basin in the vicinity of the Yugansky State Nature Reserve. The Bolshoy Yugan River, Nyogusyakh River, Lake Yegipamynglor, as well as a number of floodplain lakes were studied. We collected 29 species of water mites from 12 families, including a rare species, Lebertia oblonga Koenike, 1911. The distribution and seasonal dynamics of these water mites were investigated. In the rivers, water mites are represented by rheophilous fauna, which, albeit its regular occurrence in samples, is low in abundance and diversity of species. The fauna of stagnant waters is more numerous and diverse, and is represented by eurytopic species. Only two of the eurytopic species are common to rivers and lakes.

“…Many characters of the Chinese male specimens in our study, such as with extended and fused chitinous plates in dorsum and venter, pre- and postgenital sclerite weakly developed, and with a rounded platelet in front of the genital field (Figures 10–11), are typical characters of the male sex. On the contrary, most characters of the Turkish male specimens, e.g., with smaller and unfused chitinous plates, the pregenital sclerite is crescent-shaped and without a rounded platelet in front of the genital field, are the typical characters of the female sex (Di Sabatino et al 2010). In our study, the Chinese male specimens also match the female of S. rostratus with the support of molecular data.…”
