Fauna of Uropodina mites (Acari: Mesostigmata) of decayed tree stumps and hollows in Poland

Автор рассматривает результаты исследований фауны клещей Uropodina истлевших пней и дупел деревьев в Польше. В исследуемом материале охватывающем 188 образцов он обнаружил наличие 41 вида указанных клещей общим числом 2102 особей (табл. 1). Автор характеризует фауну клещей Uropodina исследуемых мероце- нозов и обсуждает сходство видового состава этой фауны в зависимости от вида дерева.Results of investigations of the fauna of Uropodina mites of decayed tree stumps and hollows in Poland are presented by the author. Occurrence of 41 species with 2102 specimens of the mites as mentioned above were found by him in the material investigated comprising 188 samples (Table 1). The characteristics of the Uropodina mites of the merocenoses under study is presented and similarity of the species composition of this fauna depending on the tree kind is discussed

Stability of malacocoenoses in an ash-elm forest based on two-year observations

The paper presents results of two-year (2003–2005) monthly studies on terrestrial malacocoenoses in an ash-elm forest (Fraxino-Ulmetum) near Duszniki in western Wielkopolska (W. Poland). Species composition, dominance structure and abundance of malacocoenoses of selected plots were analysed. Twenty species of ten families were recorded, represented by 7,619 specimens. The main components of the malacocoenoses were Nesovitrea hammonis (Ström), Columella edentula (Drap.), Vallonia costata (O. F. Müll.), Punctum pygmaeum (Drap.), Cochlicopa lubricella (Porro) and Vertigo pusilla O. F. Müll. The species composition was stable but the abundance varied considerably

Ruthenica filograna (Rossmassler, 1836) (Gastropoda: pulmonata: Clausiliidae) in malacocoenoses of deciduous forests in various regions of Poland

Malacocoenoses containing Ruthenica filograna (Rossm.), a forest-dwelling clausiliid, were studied in two localities in Poland: the nature reserve Dębno nad Wartą (Wielkopolska region) and the Valley of Pieninski Potok (Pieniny Mts). The malacocoenoses were composed of 20 and 42 species, respectively. In Debno nad Wartą R. filograna was the most frequent and abundant species; in the Valley of Pieniński Potok the most frequent and abundant species was Vitrea diaphana. The structure of the two communities differed also in other respects. The gastropod density in the two localities was similar (168 and 185 individuals · m–2, respectively), but their species composition was not, with only six species in common (Nei index 0.22)

Tarsonemus lucifer (Schaarschmidt, 1959) in Poland

Авторы приводят результаты исследований по морфологии и экологии клеща Tarsonemus lucifer (Schaarschmidt, 1959) (Acari, Heterostigmae ) в Польше. Экологический анализ проводился на основании двухлетних фенологических изысканий проведенных в лиственном лесу заповедника Якубово около города Пневы, а биоценотический анализ - на основании 47 местообитаний клещей в Польше.The authors present results of the study on morphology and ecology of Tarsonemus lucifer (Schaarschmidt, 1959) (Acari: Heterostigmae) in Poland. Ecological analysis was based on two-year study on phenology in deciduous forest, the „Jakubowo" reserve near Pniewy, and biocenotical study of 47 habitats in Poland

Malacocoenoses of fragmented forests of Wielkopolska

Terrestrial malacocoenoses of two neighboring forest complexes in W. Wielkopolska were sampled in 2003–2004; their structure and abundance were analysed in selected plots of oak-hornbeam forest of different protection status and degree of anthropogenic transformations. Twenty species (10 families) represented by 1,588 specimens were collected. The main components of the malacocoenoses were: Nesovitrea hammonis, Aegopinella nitidula, Ae. pura, Punctum pygmaeum, Cochlicopa lubricella, Perforatella incarnata and Carychium minimum. Both species composition and abundance varied greatly between the plots. The gastropods showed no preference for old oak-hornbeam stands or plots located in nature reserves. This may suggest that even under strong anthropopressure and in much transformed environments the snails are capable of maintaining a high diversity
