AbstractThe aim of the present study was to establish the effect of management type and of environmental variables on the structure, abundance and species richness of soil mites (Acari: Mesostigmata) in twelve urban green areas in Bucharest-Romania. Three categories of ecosystem based upon management type were investigated: protected area, managed (metropolitan, municipal and district parks) and unmanaged urban areas. The environmental variables which were analysed were: soil and air temperature, soil moisture and atmospheric humidity, soil pH and soil penetration resistance. In June 2017, 480 soil samples were taken, using MacFadyen soil core. The same number of measures was made for quantification of environmental variables. Considering these, we observed that soil temperature, air temperature, air humidity and soil penetration resistance differed significantly between all three types of managed urban green area. All investigated environmental variables, especially soil pH, were significantly related to community assemblage. Analysing the entire Mesostigmata community, 68 species were identified, with 790 individuals and 49 immatures. In order to highlight the response of the soil mite communities to the urban conditions, Shannon, dominance, equitability and soil maturity indices were quantified. With one exception (numerical abundance), these indices recorded higher values in unmanaged green areas compared to managed ecosystems. The same trend was observed between different types of managed green areas, with metropolitan parks having a richer acarological fauna than the municipal or district parks.

The aim of the study was to compare the soil mite communities in anthropogenous birch stands of different origin with each other and with natural forests at the same latitude. Nine sites were investigated: three birch stands (Betula pendula Roth) planted ca. 30 years prior to the study after clear-cutting of spruce stands ("birch after spruce"), three birch stands planted ca. 30 years earlier on arable soil that had been under cultivation until reforestation ("birch after field"), and three natural deciduous forests. These were sampled twice, and microarthropods were extracted, counted, and identified. There were clear differences between birch stands established after spruce forest and after cultivation and between these and natural deciduous forests. The communities of birch after spruce were rather similar to those of natural spruce forests, but the population densities were lower. The populations in birch after field were generally very low. There were also conspicuous differences among replicates of the same kind of forests. All the dominant species in the study sites are common members of the forest soil fauna. The communities of birch after field could be characterized as impoverished forest communities. Soil pH and the removal of the litter layer by earthworms were regarded as the most important factors explaining the observed differences.

Abstract The research was carried out in three types of habitats located in the seasonally flooded area of the Vistula River within Wielka Kępa Ostromecka Reserve: Salicetum albo-fragilis, Fraxino-Alnetum and Populetum albae. 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.

The European beech (Fagus sylvatica L.) is a dominant tree species in European forests and it has a huge ecological significance and high economic value. Due to its large dimensions, it can produce large amounts of decayed wood (CWD) which may be critical for maintaining the population of many rare species including mites. Many studies focused on mite (Mesostigmata) abundance, species richness, or diversity in CWD, however, our knowledge on mite biomass is still scarce. Therefore, the main aim of that study was to recognize the Mesostigmata biomass in logs and adjacent soil. In total, 90 samples (125 cm3, 5 cm depth) were collected from European beech logs and soil with litter thickness. Soil samples were collected from ecotone zone (soil near the log) and further three distances—0.5 m, 1.0 m, 1.5 m away from the log. Body length and width were measured for each individual of rare species and in the case of common species at least for 10 individuals. Our study revealed the highest mite biomass in CWD and soil near to the log (ecotone). Total male biomass was the highest in CWD and differed significantly from all other soil microhabitats. Female biomass did not differ between soil and CWD, whereas deutonymphs biomass differed between CWD and soil 1.0 m away from the log. Mean abundance, species richness, and diversity did not differ between the microhabitats. Decaying logs were dominated by Janietella pulchella whereas soil by Veigaia nemorensis. In conclusion, decayed European beech logs maintain the highest male and deutonymph biomass when compared to adjacent soil. Beech logs are important microhabitats for Mesostigmata mite communities, where they reached the highest abundance.
