Soil under <em>Reynoutria</em> displayed higher carbon, nitrogen and phosphorus contents but no differences were detected regarding enzyme activities between invaded and uninvaded sites. Moreover, the magnitude of <em>Reynoutria</em>’s effects differed depending on local conditions, with greater effects when total carbon and phosphorus-related enzymes were relatively low.

The vast majority of springtail community studies focus on the belowground (eu- and hemiedaphic) forms that are generally collected by taking and extracting soil cores. Few investigations have dealt with epedaphic Collembola that are usually captured with pitfall traps, and only very few studies so far covered all three life forms. When epedaphic and belowground species are sampled using both methods simultaneously, core data (true densities, [individuals m<sup>−2</sup>]) and pitfall data (activity abundances, [individuals trap<sup>−1</sup> length of trapping period<sup>−1</sup>]) may be analyzed independently, but are incompatible in a common statistical framework. As a remedy, two competing numerical approaches to estimate true densities from activity abundances have been described in literature: the nested-cross array and the two-circle method. Attraction or deterrence effects of trap preservation fluids bias the density estimation of the nested-cross array, but not of the two-circle method. To determine whether this bias may be expected for Collembola, and thus which of the two methods should be used in future studies, we experimentally tested potential effects of preservation fluids on trap catch rates. Three preservation fluids (sodium benzoate, propylene glycol, formaldehyde) and a detergent (Tween80) significantly increased the number of captured springtails, thus demonstrating an attraction effect and the deficiency of the nested-cross array. In future studies of collembolan communities, we therefore suggest complementing the traditional focus on the eu- and hemiedaphic life forms by sampling epedaphic species using pitfalls, and subsequently remodelling the trapping data with the two-circle method.</div></div>","PeriodicalId":49711,"journal":{"name":"Pedobiologia","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of urbanization-induced metal pollution on soil microbial communities remains largely underestimated. This study examines soil microbial communities and properties beneath the canopy of three deciduous and three evergreen trees in urban parks, situated at varying distances from the city center. The results demonstrated that urbanization consistently alters soil physicochemical properties, including pH, soil moisture, and specific heavy metal contents (e.g., Zn, Mn, Cr). The α-diversity of soil bacterial community was significantly influenced by pH and specific heavy metals (e.g., Cr, Cd), whereas the α-diversity of fungal community was affected by pH, independent of heavy metal concentrations. The response of heavy metal content to urbanization exhibited a consistent pattern across both deciduous and evergreen trees, although the effect differed between these tree types. Furthermore, urbanization impacts the diversity, structure, composition and network of soil microbial communities. Notably, the Shannon index of soil fungal communities under deciduous species shows an initial increase, followed by a decline as urbanization intensifies. In contrast, the Simpson index of soil bacteria under evergreen tree species decreases with increased urbanization. Moreover, urbanization alters soil bacterial networks, with higher network density observed in less urbanized areas. It may also affect microbial functions, such as xenobiotic and lipid metabolism.

Thus, saline soils categorized into low-salinity (LS), medium-salinity (MS), and high-salinity (HS) based on electrical conductivity (EC) were collected. The 16S rRNA high-throughput sequencing analysis was performed to analyze the effects of salinities on soil bacterial community patterns, as well as the relationships between soil bacterial communities and environmental factors. The results showed that Actinobacteriota, Proteobacteria, Chloroflexi, Firmicutes, Acidobacteriota, Gemmatimonadota and Bacteroidota accounted for almost 90 % of all the bacterial community. The linear discriminant analysis effects (LDA &gt; 3.7) showed that 6, 5 and 3 biomarkers were present in LS, MS and HS soils, respectively, which indicated EC was an important factor influencing the saline soil bacterial community patterns. Redundancy analysis further revealed that the primary environmental parameters impacting the bacterial community were pH, EC, nitrate nitrogen, available phosphorus, total phosphorus, and soil organic matter. According to network analysis, the microbial network complexity was increased steadily with increasing of soil salinity.

However, the prescribed burn had no effect on either the biophysical environment nor on arthropod abundance and diversity during the subsequent incubation period of &gt;5 months after the burn. Furthermore, the prescribed burn substantially increased the immobilization of iron (Fe) and manganese (Mn), and decreased sulfur (S) concentration in the decomposing litter. Prescribed burn had no interactions with substrate quality for percent mass remaining (PMR) and elemental release or accumulation. Low substrate quality <em>D. annulatum</em> litter with a carbon to phosphorus (C/P) ratio of 614 was associated with higher microbivore diversity and higher predator density than higher substrate quality <em>M. maximus</em> litter with a C/P ratio of 266 during the entire incubation period. Lower initial concentration of litter P, magnesium (Mg) and calcium (Ca) in <em>D. annulatum</em> resulted in higher immobilization of these elements in decomposing litter than in <em>M. maximus</em>.
