“…Microorganisms inhabiting soil microhabitats are both a critical indicator of ecosystem health and an important driver in the biochemical cycling of nutrients (such as carbon, nitrogen, and sulfur) . Microplastics can be colonized by microorganisms, protozoa, and algae, forming a distinctive niche. − This new human-made ecosystem is named the “plastisphere” . Research has shown that the plastisphere exhibits great differences in the microbial community and assembly from that of the surrounding environment. , They can not only serve as hotspots of potential pathogens but also interfere with the biochemical cycling balance process of nutrients in the surrounding environment. − Imbalances in the biochemical cycling of nutrients such as nitrogen and sulfur may cause the loss of nutrients or the release of harmful gases. − However, the crucial roles of residual microplastic film in microbial community structure, assembly, and biogeochemical cycling of nutrients (i.e., nitrogen and sulfur), especially in farmland systems, are largely vague, constraining the understanding of the adaptation mechanism of the plastisphere.…”

How the plastisphere mediated by the residual microplastic film in farmlands affects microhabitat systems is unclear. Here, microbial structure, assembly, and biogeochemical cycling in the plastisphere and soil in 33 typical farmland sites were analyzed by amplicon sequencing of 16S rRNA genes and ITS and metagenome analysis. The results indicated that residual microplastic film was colonized by microbes, forming a unique niche called the plastisphere. Notable differences in the microbial community structure and function were observed between soil and plastisphere. Residual microplastic film altered the microbial symbiosis and assembly processes. Stochastic processes significantly dominated the assembly of the bacterial community in the plastisphere and soil but only in the plastisphere for the fungal community. Deterministic processes significantly dominated the assembly of fungal communities only in soil. Moreover, the plastisphere mediated by the residual microplastic film acted as a preferred vector for pathogens and microorganisms associated with plastic degradation and the nitrogen and sulfur cycle. The abundance of genes associated with denitrification and sulfate reduction activity in the plastisphere was pronouncedly higher than that of soil, which increase the potential risk of nitrogen and sulfur loss. The results will offer a scientific understanding of the harm caused by the residual microplastic film in farmlands.

“…Colonisation of artificial stones by macroinvertebrates has been extensively studied (e.g., Khalaf et al, 1980;Rosa et al, 2013), and artificial stones have been highlighted as a useful experimental substrate for assessing colonisation and succession (Rosa et al, 2013). Artificial stones provide stable and suitable substrates for colonisation (Pfeiffer et al, 2022) as they are less susceptible to being carried by flowing water (Friedmann and Galun, 1974;Death and Winterbourn, 1995). Furthermore, their uneven surfaces facilitate the movement and attachment of macroinvertebrates in reservoirs or slow-flowing river system, offering greater stability and availability of microsites for colonisation (Ayres-Peres et al, 2006).…”

The demand for macadamia nut production worldwide has led to increased use of pesticides and chemicals for pest and disease control. Reservoirs in these macadamia farming sectors are at . The current study investigated macroinvertebrate colonisation and succession associated with two macadamia orchards and two communal area reservoirs. The potential effects of stressors from these land uses was tested for and compared using stone substrates over a 6-week period. Stone substrates from both reservoir types were abundantly colonised over time and the total macroinvertebrate taxa and abundance showed an increasing trend across the sampled weeks, with macadamia orchards having the highest number of macroinvertebrate taxa. Strong ecological succession was observed across reservoirs, with the initial succession of early colonisers – i.e., Chironominae (, Ostracoda (and Anax sp. (predator) within communal area reservoirs, and Chironominae, Ostracoda Radix natalensis (scrapers) in macadamia orchard reservoirs – followed by predatory colonisers such as Gyrinidae larvae, Trithemis sp. (macadamia orchard reservoirs), and Ranatra sp. (communal area reservoirs). Macroinvertebrate community structure differed significantly across sites and weeks, with no similarity being observed for communities across the different reservoirs. Redundancy analyses further highlighted 11 sediment chemistry variables (i.e., pH, resistivity, P, K, Na, Ca, Mg, Cu, B, Fe and S) which were significantly related to macroinvertebrate community structure. Thus, sediment variables were found to be better predictors of macroinvertebrate community structure in macadamia orchard reservoirs than communal area reservoirs. Consequently, we concluded that differences in colonisation ability among taxa and environmental stressors were important factors driving succession. These results add to the understanding of the macroinvertebrate colonisation processes and environmental stressors within agricultural landscapes, which can aid in the development of conservation management of freshwater ecosystems.
