Integrated farming of rice (IFA), as a time-honored agricultural model, can effectively increase productivity and provide ecological benefits. Rice-wheat rotation rice-crayfish ( Procambarus clarkii ) are two most widely applied IFA patterns in China. In this study, we compared the differences soil microbial communities predicted their functions these models by sequencing 16s rRNA analyzing bioinformation. The results showed that crayfish increased abundance diversity microorganisms. main differentially abundant phyla between groups were Actinobacteriota, Bacteroidota, Desulfobacterota, while genera Bacteroidetes_vadinHA17 , Sphingomonas Thiobacillus . Similarity Percentages (SIMPER) analysis indicated species also had highest contribution to composition groups. Random forest prediction was employed identify potential biomarkers distinguish communities. Spirochaetota identified biomarker phyla. Streptomyces Kribbella Paludibacter could serve genera. Functional Annotation Prokaryotic Taxa (FAPROTAX) revealed dominant bacterial rice-wheat model aerobic chemoheterotrophy chemoheterotrophy. contrast, more diverse, primarily including methylotrophy, human pathogens all methanotrophy. co-occurrence network enhanced modularity community, fewer nodes edges, which implying internal connections. conclusion, wheat planting drove significant paddy fields, with Actinobacteriota Desulfobacterota biomarkers. Compared cultivation, system incorporating richness functions, promoted presence keystone connecting roles. Our study would not only clarify effects different on communities, should valuable insights for future adjusting cropping controlling current problems.

Seaweed cultivation contributes to coastal carbon sequestration making it a compelling strategy mitigate global climate change. Porphyra (commonly known as nori) is an economically important seaweed have high release rates for biogenic dissolved and particulate organic matter (DOM POM). However, the impact of on dynamics remains unclear. To fill this knowledge gap, we conducted investigations examining quantity optical properties DOM POM, microbial community structures relevant environmental factors along continuum from subtropical river through its adjacent zone during non-cultivation periods. Dissolved (DOC) concentration was significantly elevated versus period, while (POC) decreased, thereby resulting in higher DOC/POC ratio water column. Endmember mixing analysis further suggested that autochthonous dominated both periods, with limited inputs terrestrial carbon. Redundancy revealed more modules mediated transformations leading 169% estuarine addition microbially-sourced humic-like C3 compared period. Our findings demonstrate enhanced by promoting production transformation refractory DOM, which has implications sustainable management development blue strategies.

Seaweed plays a critical role in marine carbon sequestration due to its high release rate of organic matter. However, the impacts Porphyra cultivation on concentration and composition dissolved, particulate sedimentary matter (DOM, POM SOM) coastal zones remain unclear. Herein, we investigated optical properties DOM, SOM along transect from subtropical Chi River adjacent zone Dayu Bay (southeast China) during late stage. The results revealed that all types were predominantly characterized by highly autochthonous sources, contrasting sharply with allochthonous, terrestrial sources observed at freshwater sites. estuarine mixing model principal component analysis further indicated dynamics are primarily controlled cultivation, relatively limited contributions riverine inputs, sediment porewater sources. leads significant additions protein-like components water sediment. Microbial degradation incubations DOM demonstrated promotes situ production humic-like (peak M) water. exhibited higher microbial transformation efficiency into refractory than POM, suggesting more substantial sequestration. Our findings underscore potential enhance ecosystems.
