“…Therefore, the nearest neighbor parameter of a reference point is the most important parameter in calculating the Similarity scores [88]. The higher Similarity scores (or a high -diversity index) indicates a low level of similarity between soil species and vice versa [90]. The study looks into the Similarity scores of the soil samples before and after the use of GW treatment.…”

Fresh water is an increasingly scarce resource in both urban and rural developments. As a response to this challenge, non-potable water reuse is on the rise. This research explored a potential off-grid system for water purification, consisting of a staircase wetland with terracotta pot plants working as a filter for greywater. The study further investigated the physicochemical properties of the greywater and the soil before and after the wetland purification. Results showed that the filtered water satisfied all requirements for water reuse, e.g., pH, turbidity, and total coliforms. The research then uniquely investigated the effect of greywater on the soil biodiversity and soil biomass using soil DNA extraction and the tea bag index testing method. The filtered greywater absorbed by soil decomposed the soil faster and stabilized it better compared to tap water-absorbed soil or unfiltered greywater. The DNA generation sequencing revealed no significant differences in alpha diversity between control and treatment samples. The beta diversity differences were significant. This nature-based solution can lead to reduced load on the sewage system, resulting in less wastewater generation.

“…The reuse of GW is an emerging field of research. However, despite the known effects of GW on soil physicochemical properties [90,91], the impact of GW on soil microbial species remains significantly underexplored. In this paper, for the first time, the impact of the GW on the soil microbial species is studied.…”

“…On the other hand, Ravit et al ( 2003) observed decreased microbial richness and soil enzyme activity in invaded wetlands. Similarly, bamboo expansion in Chinese forests caused a decline of both α-and β-diversity of soil nematodes (Xiao et al 2023). The problem of such studies is that they rely on manipulative or observational experiments with a single species or very few species, the comparability with our study is thus limited.…”

Background and Aims Invasive species are a threat to the conservation of biological systems. In Central Europe, riparian ecosystems are especially susceptible to plant invasions, as waterflow mediates the spread of plant propagules, while invasive species may then affect soil including soil microbial communities. As waterflow also enhances connectivity among different segments of a river, spatial continuity of abiotic as well as biotic components of riparian ecosystems is expected. Methods We studied activity and functional diversity of microbial communities in three headwater streams in Central Europe. Plant diversity, soil properties and soil microbiota were assessed on 20 sample plots per river regularly distributed along the streams. Soil microbial activity and community-level physiological profiling were used to study the soil microbial community. Results Although the α-diversity of plants and soil microbiota was comparable, plant communities were substantially more differentiated than microbial communities. Richness in alien and invasive plants significantly differed among rivers, which was reflected in different spatial patterns and trends of microbial activity and diversity. A high level of spatial continuity and clearest longitudinal trends were observed in the Kysuca river with straightened riverbed and a high occurrence of artificial surfaces in the adjacent areas. The number of both alien and invasive plants significantly affects the composition of microbial functional groups of riverbed soils. Conclusion Continuity of processes in riparian ecosystems was confirmed also for headwater streams. However, the extent to which it applies to a particular stream strongly depends on particular environmental setting and stream characteristics.

“…Additionally, the expansion of bamboo has increased soil pH [10], changed terrestrial water and nutrient cycles [11,12], affected soil microbial community structures [13], and so on. In recent years, considerable research has been carried out on the process of bamboo expansion [14,15] and the mechanism [14,16,17] and the expansion effects [4,18,19]. However, there is a lack of research on the bamboo expansion processes and patterns, which hinders the understanding of the bamboo expansion process and the research on expansion prevention and control.…”

Bamboo (Phyllostachys edulis) expansion to native adjacent forests has become an increasingly serious problem; however, expansion patterns of bamboo are still lacking research, especially at a community scale. Quantitative research on bamboo expansion patterns plays a significant role in understanding the bamboo expansion process, as well as expansion prevention and control. We analyzed the change in expansion pattern, expansion index, and expansion rate of bamboo in the bamboo-broadleaf transition zone sample plots, specifically from 2017 to 2021 and from the bamboo forest (representing the late stage of bamboo expansion) to the bamboo expansion front (representing the early stage of bamboo expansion). We found that the expansion of bamboo is a patchy expansion, including inner filling patch, boundary expanding patch, transboundary leaping patch, expansion–infill mixed patch, and stationary patch. From the early stage of bamboo expansion (year 2017 and bamboo expansion front) to the late stage of bamboo expansion (year 2021 and bamboo forest), the type of bamboo expansion patches transitioned from boundary expanding patch to inner filling patch and boundary expansion–inner infilling mixed patch. Additionally, the expansion rate of bamboo showed a declining trend. From 2017 to 2021, the bamboo forest (position of 0–20 m) and expansion front (position of 60–80 m) declined by 0.53 m/2a and 0.47 m/2a, respectively. Our research reveals that bamboo expansion exhibits a patchy expanding process, characterized by a sequence of “first spreading outward and then filling inward”, whether viewed from the type of expansion pattern or the expansion rate. This process involves continuous plaque addition, expansion, merger, and filling to complete the expansion of a bamboo population. These findings provide valuable insights into the process of bamboo expansion and have important implications for the management and control of bamboo forests.
