    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.
