Mites (Acari: Mesostigmata) inhabiting nests of the white-tailed sea eagle Haliaeetus albicilla (L.) in Poland

During 1997—2002, 105 samples of mites were collected from 34 nests of the white-tailed sea eagle in Poland. The material included 9,724 specimens of Mesostigmata belonging to 86 species. The mite communities were dominated by species of the families Parasitidae, Macrochelidae and Ascidae. The most abundant species were Alliplzis halleri, Androlaelaps casalis, Parasitus fimetorum and Macrocheles merdarius that altogether made up 48% of all the specimens collected. Alliplzis halleri and Androlaelaps casalis were also the two most frequently found mites. A summary is presented on the biology and distribution of the abundant species

Microgeographic diversity of Uropodina (Acari Mesostigmata) communities in dead wood and tree hollows

The current study is aimed at establishing species composition of Uropodina mite fauna in dead wood habitats in a selected forest complex in western Poland. In this case the study focuses on three natural reserves of Wielkopolska. In 278 samples of dead wood and 71 from tree hollows collected between 2002-2004, 27 species of Uropodina were found. The material collected from the tree hollows contained only 12 species. The two species that were most numerous in the analysed material were Oodinychus ovalis and Olodiscus minima. The lower number of species inhabiting the tree hollows stems from the fact that such microhabitats are isolated inaccessible places. The main factor that is responsible for the difference in the abundance of uropodine mites in both microhabitats are seasonal changes in temperature. Moreover, the results of the analyses show that species composition of Uropodina communities in dead wood and tree hollows can be different even within one forest complex, which suggests that the process of diversification in Uropodina communities inhabiting dead wood merocoenoses probably takes place at the microgeographic level

Lack of specialist nidicoles as a characteristic of mite assemblages inhabiting nests of the ground-nesting wood warbler, Phylloscopus sibilatrix (Aves: Passeriformes)

Bird and mammal nests provide microhabitats that support a range of other species, including invertebrates. However, the variation between communities of nest-dwelling invertebrates in different nests is poorly understood. The major aim of this study was to analyze the assemblage structure of mites from the suborder Uropodina (Acari: Mesostigmata) and from superfamily Crotonioidea (Acari: Oribatida) inhabiting nests of the wood warbler, Phylloscopus sibilatrix (Aves: Passeriformes), located on a forest floor in Białowieża Forest, in eastern Poland. We also assessed the correlation between the nest material used by the birds with the assemblage structure of Uropodina mites, and compared the results with published studies of the nests of other birds and a mammal (common mole, Talpa europaea), and also with communities of mites inhabiting the soil. The field research was conducted in the strict nature reserve of the Białowieża National Park, a near-primeval European temperate forest. In 2019, immediately after the breeding period, 69 wood warbler nests and 439 soil samples were collected. Analyses revealed assemblages of Uropodina mites inhabiting the nests that consisted of 14 species, mostly common soil species. Only five species of oribatid mites from superfamily Crotonioidea were present in the nest material. Analyzed nests had a high percentage of tree leaves and grass blades, whereas moss was the least frequent component of the nest material. The Uropodina mites were more abundant in the nests that had greater amounts of grass blades, but similar relationships were insignificant for the nests with varying amounts of tree leaves or moss. The assemblages of Uropodina mites inhabiting wood warbler nests were very similar to those found in soil and nests of the common mole, but they lacked typical nest-dwelling species of Uropodina (i.e., specialized nidicoles)

It was described from Germany, and has subsequently been recorded from Albania, Czech Republic, France, Germany, Poland, Slovakia and Ukraine (Fig. 36), in the litter of oak-hornbeam forests and beechwoods. Wiśniewski & Hirschmann (1993) recorded this species in Lithuania, but this is a misidentification of specimens of Neodiscopoma as C. erlangensis. In Poland this species is never abundant (Fig. 67 C). It occurs in mixed deciduous forests, lowland and Carpathian beechwoods, fir-beech forests, marshy meadows, oak-hornbeam forests, fir forests, and parks. It is occasionally also found in grasses on non-limestone rocks, thickets of various types, grasses on limestone rocks and in rotten tree trunks. Its optimum altitude is below 400 m a.s.l.Published as part of Stachowiak, Marcin, Halliday, Bruce & Bloszyk, Jerzy, 2008, Review of the genus Cilliba von Heyden (Acari: Uropodina: Cillibidae), pp. 1-42 in Zootaxa 1881 on pages 15-19, DOI: 10.5281/zenodo.18419

Cilliba

Genus Cilliba von Heyden, 1826 Type species: Notaspis cassideus Hermann, 1804, by original designation We have previously published a comprehensive diagnosis of this genus (Bloszyk et al., 2006). The only other genus in the family Cillibidae is Australocilliba. The two genera may be distinguished as follows: Cilliba: tarsus I without claws; metapodal line absent; epigynium of female without an anterior process; genital plate of male at level of coxae III-IV; Australocilliba: tarsus I with small claws; metapodal line distinct; epigynium of female with distinct anterior process; genital plate of male behind coxa IV. These and other differences between the two genera are also described in Athias-Binche & Bloszyk (1988). On the basis of this diagnosis, we now recognise eight species of Cilliba. All occur in Europe and one (C. athiasae) extends into North Africa. Some authors have described species of Cilliba that are now placed in other genera, some species have been synonymised, and the placement of some other species cannot be determined because the available information is inadequate. The present composition of the genus is summarised in Table 1.
