In the soil of Salicetum albo-fragilis Veigaia nemorensis and Trichouropoda ovalis were abundant, while Fraxino-Alnetum was dominated by Rhodacarellus silesiacus, and Populetum albae was overwhelmed by Rhodacarellus silesiacus and Dinychus inermis. Only between the Mesostigmata communities populating Fraxino-Alnetum and Populetum albae there were no statistically significant differences recorded in the distribution of abundance. The most similar, from the qualitative, quantitative and qualitative-quantitative point of view were Mesostigmata communities inhabiting Fraxino-Alnetum and Populetum albae. The numerous occurrence of Rhodacarellus silesiacus population in the soil of Fraxino-Alnetum and Populetum albae is most probably the result of succession changes within those habitats, and the species itself can be seen as an indicator of those habitats undergoing the process of a riparian forest transforming into an oak-hornbeam forest vegetation type.

Among them, S. giganteus is new to the fauna of Poland.

In the Krka National Park, Brač Island, and near the town of Makarska, 320 samples were collected from various microhabitats: soil, grass and moss ground cover, wet moss, needle litter, moss covering tree trunks, and decaying wood). Altogether, 2097 mites of 56 gamasid species were recorded. Dominant species were: Polyaspis patavinus (Brač Island), Zercon fageticola (Makarska), and Cheiroseius serratus (Krka National Park). Analyses of ecological preferences and zoogeographic distribution were made for Polyaspis patavinus, Cheiroseius serratus, Zercon fageticola, Z. berlesei, Z. athiasi, Asca nova and A. aphidioides.

We recorded there 93 gamasid species of 21 families in a total of 18 tree-hollows. Differences in the dominance structure of gamasid communities at the levels of family and species indicated dissimilarities in the mite communities, depending on tree species and intensity of human impact. The chestnut tree-hollows in both areas were dominated by mites of the family Urodinychidae (with the dominant Uroobovella pyriformis in both cases). The lime tree-hollows were colonized mostly by the Trematuridae (Trichuropoda ovalis) and the Digamasellidae (Dendrolaelaps tenuipilus) in the rural area, whereas by the Ascidae (Iphidozercon gibbus) in the city. The gamasid communities of willow hollows were dominated by the Trematuridae (Trichouropoda ovalis) in the urban area, and by the Digamasellidae (Dendrolaelaps longifallax, D. zwoelferi) in the rural area. Some rare species (e.g. Microgynium rectangulatum or Microsejus truncicola) were also recorded, mostly in the rural area.

Five phases could be recognized. Phase I involved inspection of the substrate. In phase II the female rhythmically moved her gnathosoma and first pair of legs. After an inactive phase III, the soma was raised (IV), and the egg was laid (V). In the actual egg laying three sub-phases could be distinguished: internal egg movement, placing the egg in front of the gnathosoma, and depositing the egg using the chelicerae. The palps and first pair of legs were used to position the egg between the chelicerae. The whole process took on average 333 ± 22 s.

Oviposition consisted of six sequential phases. The first phase (I) involved inspection of the substrate. In the second phase (II) there were rhythmic movements of the first pair of legs and slight reciprocating movements of the body. The third (III) was a resting phase. In the fourth phase (IV) the gnathosoma was lowered and the body was raised. In the next phase (V) there were two sub-phases. During the first (Va), the female held the egg below the gnathosoma. In the second sub-phase (Vb), the gnathosoma moved up holding the egg, which was then placed on the substrate. The last phase (VI) involved intense 'cleaning' movements of the chelicerae and palps. During Va a protective external eggshell structure is gradually formed, involving a phase where the egg shell is sticky. After moving the egg to the substrate, the female freed her palps and chelicerae from the sticky egg shell and cleaned her gnathosomal appendages. Phases II-V took on average 207 ± 69 s.

Contribution to succession of mite (Acari) communities in the soil of Tilio-Carpinetum TRACZ. 1962 in northern Poland. Acta zool. cracov., 55(2): 47-57. Abstract. Research on the mite (Acari) succession was carried out within six deciduous forest stands of various ages dominated by lime trees (Tilia cordata MILL.). The general mite density was correlated with the age of each stand (r=0.596). Four orders of mites were recorded the Cryptostigmata were dominant and their abundance initially decreased and then increased following the ageing of the forest stands. A similar tendency was recorded for the Mesostigmata. The abundance of the Astigmata presented a general increasing tendency and was positively correlated with the age of the forest stands. High correlations noted between the density of the Cryptostigmata, Mesostigmata and Prostigmata can indicate trophic and competitive relations between those mite communities. Among the families belonging to the Mesostigmata four succession trends of abundance and percentage share changes were found: creative (Macrochelidae and Trematuridae), regressive (Ascidae), rise and fall (Pachylaelapidae, Parasitidae, Veigaiidae and Laelapidae) and restorative (Rhodacaridae).
