Stable Bacterial Cores and Patchy Eukaryotic Communities Shape the Summer Microbiomes of Patagonian Fjord Ecosystems Across Spatial, Functional and Temporal Gradients [PDF]
Environ Microbiol RepOur study shows that microbial community diversity in Patagonian fjords varies with glacial influence and salinity, with a widespread bacterial core but a patchier eukaryotic core. Distinct co‐occurrence networks and marked short‐term community shifts occur in water‑ versus land‐terminating glacier fjords, underscoring meltwater influence in this ...
