摘要

Aquatic and terrestrial ecosystems are intricately linked, supporting cooperative interactions in response to climate change. However, the extent of microbial connections between soil and freshwater systems, particularly across seasons, remains poorly understood. We investigated the relationships of microbial communities along the soil–stream continuum and their seasonal variations using Illumina sequencing, focusing on the transfer patterns of microbial communities from soil to stream water. The results showed that the alpha diversity of the fungal community in the soil–stream continuum varied significantly across seasons, with higher diversity but lower richness observed during the dry season. The shift from the dry to the rainy season increased fungal stochasticity and decreased bacterial stochasticity, while most bacterial groups related to carbon and nitrogen cycling became less abundant. Interactions between bacterial and fungal communities were evident, indicating microbial similarities across the soil–stream continuum. In the continuum, soil bacterial inputs contributed approximately 50% to stream communities, while soil fungal inputs accounted for 38%. Microbial community similarity was significantly higher in the dry season due to lower water temperatures. These findings highlight the dynamic microbial connections between terrestrial and aquatic ecosystems and how they shift with seasonal changes, advancing our understanding of interactions among different ecosystems.
