    Snippet: Hierarchical clustering additionally showed that two biological replicates collected at the same location and time point (April samples 9.1 and 9.2), grouped with high concordance; this indicates that spatiotemporal trends are discernible even within a highly localised context.

    Document: Hierarchical clustering additionally showed that two biological replicates collected at the same location and time point (April samples 9.1 and 9.2), grouped with high concordance; this indicates that spatiotemporal trends are discernible even within a highly localised context. Besides the dominant core microbiome, microbial profiles showed a marked arrangement of time dependence, with water samples from April grouping more distantly to those from June and August (Figure 2c ). Principal component analysis (PCA) (Figure 3a ; Extended Data Figure 4 ) revealed that the strongest differential abundances along the chronological axis of variation (PC3) derived from the higher abundance of Carnobacteriaceae in April (Figure 3b ). This family is known for its occurrence in waters with low temperature 20 .
