Opis:
This paper is a study of diversity and seasonal abundance of soil inhabiting arthropod fauna and their interrelationships with the edaphic factors like temperature, moisture and pH in flower garden, vegetable garden and uncultivated area dominated by weeds in Ramakrishna Mission Ashrama Campus, Narendrapur, South - 24 Parganas, West Bengal. The soil arthropods were collected with the help of Berlese-Tullgren funnels. Altogether, 591 arthropods belonging to 7 different groups viz., Acarina, Arachnida, Collembola, Coleoptera, Diptera, Hymenoptera and Psocoptera were extracted from each of the three plots every month during the entire survey period (August 2018 – July 2019). Microarthropod abundance was found to be greater in uncultivated areas (266 individuals) as compared to that of the flower and vegetable gardens where different agronomic practices are adopted and traditional means of garden nurturing viz. tilling, raking, weeding, etc. are followed. Of the total population in all three plots, mites were the most dominant group (37.06%), followed by ants (25.21%) & springtail (19.29%) populations. Soil arthropods populations are greater in the monsoon season (227 individuals), followed by premonsoon (188 individuals) & postmonsoon (176 individuals).

Opis:
The aim of this study was to compare colonization of pine chips without supplements and pine chips supplemented with forest litter, peat and lignite by mites (Acari), and particularly oribatid mites (Oribatida) in a two-year cycle. The study was conducted in the years 2013-2014, on microplots established in a belt of trees in a nursery in Białe Błota within Bydgoszcz Forest District. The experiment was established on four microplots (1 x 1 m). It included the following variants: C - pine chips alone, Lf – pine chips inoculated with fresh forest litter, Lf+Pe – pine chips enriched with deacidified high peat (20%) (pH 5.5-6.5) and inoculated with the litter, Lf+Li - pine chips enriched with granulated lignite (20%) inoculated with the litter. In the first year of the study, mite abundance in the chips inoculated with forest litter was significantly higher than that on microplot C. In the second year of the experiment, the abundance of these microarthropods decreased probably due to unfavorable weather conditions. The most common group of mites were usually oribatid mites that accounted for 19.7 to 80.4% of all mites. An analysis of seasonal dynamics of Oribatida abundance over the entire study cycle revealed a clear increase in their numbers in non-supplemented pine chips only on the last sampling date. Oribatida abundance in Lf variant was similar at the beginning and end of the study. Contrary to that, their number decreased in the chips supplemented with peat, and particularly those enriched with lignite. In total, 36 species of oribatid mites were identified on all microplots. The greatest boost in species diversity after the introduction of forest litter was observed in Lf chips and the smallest in Lf + Li variant. Oribatula tibialis was the most common oribatid mite in the investigated substrates. Low numbers of Oppiella nova and Tectocepheus velatus, the species having trophic associations with fungi, may indicate poor colonization of the chips, particularly those enriched with lignite, by saprotrophic organisms.

Opis:
Little is known about the impact of exotic invasive plant species on soil invertebrate communities. The influence of highly productive invader Reynoutria sachalinensis on the soil microarthropods was studied. Three sites, with different coverage of the invader, have been selected in the mixed forest in the Jura Krakowsko-Częstochowska. The lowest abundance of microarthropods and the lowest oribatid species richness were noted in the monospecific Reynoutria infestation stand. The reduction of abundance of saprophagous mites (Oribatida, Acaridida) and springtails were observed at the totally invaded site, whereas gamasid and actinedid mites reacted positively to the presence of Reynoutria. Observed abundances and species richness of microarthropods at studied sites were in accordance with theories on biodiversity. Antifungal activity of phenolic compounds present in leaves of R. sachalinensis may negatively influence on saprophagous representatives of microarthropods. On the other hand, predacious mites profited from the simplified vegetation structure.

Opis:
The article presents results of the research on microarthropods (Acari and Collembola) inhabiting fallen spruce trees. The research was conducted in the spruce forest Plagiothecio−Piceetum tatricum typicum in the Babia Góra National Park, Carpathian Mountains. Five downed spruce logs in different stage of decay and neighbouring soil were sampled seasonally. Over 91 thousands specimens of mites and springtails were collected in 140 samples. Changes in population densities of different groups of microarthropod with the age of the dead wood was analysed and compared with densities in forest litter and soil. The total number of microarthopods inhabiting downed spruce logs on the area of hectare in the studied forest was estimated.
