Microbial communities across seasonal variation in shrub encroached drylands (Bacterial 16S V4V5 Data)

Microbes play critical roles in dryland ecosystems, driving nutrient cycling, soil stability, and plant interactions. Despite their ecological importance, few studies have examined how microbial communities respond to vegetation changes in arid landscapes. The overarching goal of this study was to investigate how microbial communities respond to both biotic (i.e., vegetation) and abiotic (i.e., seasonality) factors, how they assemble in a changing landscape, and which taxa may be particularly responsive to shrub encroachment or even facilitating this transformation.

微生物在旱地生态系统中扮演关键角色，驱动养分循环、土壤稳定性维持与植物相互作用。尽管微生物具备重要的生态功能，但目前针对干旱景观中微生物群落如何响应植被变化的研究仍相对匮乏。本研究的核心目标在于：探究微生物群落如何响应生物（即植被）与非生物（即季节变化）因子、其在动态景观中的群落组装机制，以及哪些分类群对灌木入侵尤为敏感，甚至可能助力这一生态转变过程。
