Reveals the impact of latitudinal gradients on archaeal community assembly in estuarine ecosystems, indicating significant ecological implications.

The aim is to understand the spatial structure and processes of archaeal communities in estuaries across different latitudes in China.
Collected sediment samples from three estuarine regions: North China Sea, East China Sea, and South China Sea.
Utilized 16S rRNA high-throughput sequencing to analyze archaeal communities.
Employed null-model inference and molecular ecological network analyses to assess community assembly and interactions.
Archaeal communities showed clear spatial segregation across the three estuarine regions.
Community richness and network complexity increased significantly toward lower latitudes.
Deterministic assembly processes were prominent at lower latitudes, while stochastic processes became more significant at higher latitudes.
Key environmental factors identified include nitrate, ferric iron, and dissolved oxygen.

Liu et al. (2026) studied this question.
