Abstract Invasive alien plants cause major losses to native biodiversity. Nature reserves are crucial in resisting invasion, but resistance varies by habitats. To explore the variations and factors that determine invasive plant dispersal patterns different habitats, we investigated abandoned land, eucalyptus plantations, natural secondary forests Encheng National Reserve, Guangxi.

Abstract Bacteria and fungi are core microorganisms in diverse ecosystems, their cross‐kingdom interactions considered key determinants of microbiome structure ecosystem functioning. However, how bacterial‐fungal mediate soil organic carbon (SOC) dynamics remains largely unexplored the context artificial forest ecosystems. Here, we characterised bacterial fungal communities four successive planting Eucalyptus compared them to a neighbouring evergreen broadleaf forest. Carbon (C) mineralisation combined with five C‐degrading enzymatic activities was investigated determine effects on SOC dynamics. Our results indicated that significantly altered diversity increased negative associations. The decreased all plantations forest, while showed opposite trend. ratio associations due decrease SOC, ammonia nitrogen (NH 4 + ‐N), nitrate (NO 3 − ‐N) available phosphorus (AP). Structural equation modelling potential competition, based correlations, negatively associated total bacteria keystone bacteria, thereby increasing C mineralisation. Synthesis applications : highlight regulatory role association enhancing correlation between This suggests promoting short‐term management can mitigate impact this decomposition. Taken together, our study advances understanding plantations, giving us new insight into cycling forests.

Abstract Soil microbial community plays important roles in altering ecological processes and biogeochemical cycles ecosystems. However, little is known about how afforestation influences the diversity, composition, network of soil karst regions. In this study, samples were collected from one farmland (FL) three lands including bamboo forest (BA), landscape tree planting (LAT), orange orchard (ORO) a region Southwest China. The bacterial fungal communities characterized using high‐throughput sequencing approach, properties organic carbon, pH, water content, total available nutrient contents measured under different land use treatments. Results showed that conversion FL to BA LAT significantly reduced Shannon diversity community.

Appropriate fertilization can enhance forest productivity by maintaining soil fertility and improving the structure of bacterial community. However, there is still uncertainty surrounding effects combined application organic inorganic fertilizers on nutrient status community structure. A experiment was set up in an eight-year-old teak plantation with five treatments involved: mixed NPK compound (OCF), phosphorus (OPF), organic, (OCPF), (CPF) no (CK). Soil chemical properties communities were investigated, co-occurrence pattern under different compared. The results showed that contents matter nitrate nitrogen, pH values highest after OCPF treatment, which 20.39%, 90.91% 8.16% higher than CK, respectively. richness diversity bacteria underwent obvious changes, but soil's significantly altered fertilization.
