Above-ground Hymenoptera populations declined in deforested plots, while underground numbers rose. Undeforested forests supported higher densities of Coleoptera, Hymenoptera, and Arachnida. Despite similar annual biomass trends across plots, deforested areas had a greater biomass, driven by larger soil fauna. Soil total nitrogen, total phosphorus, and organic matter content increased in deforested areas and showed a strong correlation with most soil fauna, especially Diptera larvae. Following deforestation, habitat alterations have affected soil fauna's food sources, resulting in a lower trophic level for groups like Diptera, Collembola, and Hymenoptera.</p><h3 data-test=\"abstract-sub-heading\">Conclusion</h3><p>Our study underscores the significant impact of Moso bamboo expansion and subsequent felling on the soil fauna communities and food web in <i>Cryptomeria japonica</i> forests.

The aim of this study is to elucidate changes in the structure of a constructed Technosol based biofilter of a bioretention cell (BC) by means of x-ray tomography and additional physical characterization during the first years after installation under two different water regimes.</p><h3 data-test=\"abstract-sub-heading\">Methods and materials</h3><p>Two identical experimental BCs were studied to investigate structural changes in biofilter. The BCs exhibited different water regimes. BC1 collected naturally occurring rain concentrated from the nearby roof, while BC2 lacked a regular inflow of water except for several irrigation events and exhibited drier conditions overall. Biofilter was constructed using a mixture of 50% sand, 30% compost, and 20% topsoil. Undistributed soil samples were collected from the biofilter at 7, 12, 18, 23, and 31 months after BC installation.
