Short summary
Short summary
1. The vertical distribution pattern and inter-layer heterogeneity of bacterial communities in the Chukchi Sea were uncovered. 2. Water depth, oxygen levels and silicon substances acted as key environmental drivers, with intricate stable symbiotic interactions found in middle-water bacterial assemblages. 3. Stochastic processes dominated the bacterial community assembly, combined with deterministic environmental filtering effects.

Short summary
The unique microbial eukaryotic community structure and lower diversity have been demonstrated in five freshwater lakes of the Fildes Peninsula, Antarctica. Stochastic processes and biotic co-occurrence patterns were shown to be important in shaping microbial eukaryotic communities in the area. Our study provides a better understanding of the dynamic patterns and ecological assembly processes of microbial eukaryotic communities in Antarctic oligotrophic lakes (Fildes Peninsula).
The unique microbial eukaryotic community structure and lower diversity have been demonstrated...
