Abstract
Studies on the plastisphere mainly focus on the overall microbial community, neglecting the nuanced difference of its generalist and specialist subcommunities. To elucidate the intricacies of these subcommunities, we analyzed plastic films residues from greenhouse soils. The results revealed that the plastisphere influenced alpha-diversities of bacterial and fungal generalist subcommunities but not their specialist subcommunities. Stochastic processes governed the assembly of bacterial and fungal generalist and specialist subcommunities in plastisphere and surrounding soil, with the plastisphere intensifying the role of stochastic process, particularly in the assembly of generalist subcommunities. Furthermore, the species dispersal of bacterial and fungal generalist and specialist subcommunities was more extensive within plastisphere than in surrounding soil; however, in the biotic networks, the node ratio of bacterial and fungal specialists decreased in plastisphere compared to surrounding soils. Furthermore, the plastisphere diminished the significance of both generalists and specialists in sustaining network stability based on the topological parameters. Plastisphere induced significant enrichment of fungal pathogens, suggesting that plastic film may pose risk to plant performance and soil health. These results broaden our understanding of how plastisphere-induced interference affects generalist and specialist microorganisms, potentially highlighting the need for improved residue management to sustain ecosystem health and function.
期刊介绍:
Applied Geochemistry is an international journal devoted to publication of original research papers, rapid research communications and selected review papers in geochemistry and urban geochemistry which have some practical application to an aspect of human endeavour, such as the preservation of the environment, health, waste disposal and the search for resources. Papers on applications of inorganic, organic and isotope geochemistry and geochemical processes are therefore welcome provided they meet the main criterion. Spatial and temporal monitoring case studies are only of interest to our international readership if they present new ideas of broad application.
Topics covered include: (1) Environmental geochemistry (including natural and anthropogenic aspects, and protection and remediation strategies); (2) Hydrogeochemistry (surface and groundwater); (3) Medical (urban) geochemistry; (4) The search for energy resources (in particular unconventional oil and gas or emerging metal resources); (5) Energy exploitation (in particular geothermal energy and CCS); (6) Upgrading of energy and mineral resources where there is a direct geochemical application; and (7) Waste disposal, including nuclear waste disposal.
