Fig 5. Principal coordinate analysis plots of gut microbiome samples from populations that underwent mid-season shifts in feeding regime over the course of the study.

Principal coordinate analysis was performed on Bray-Curtis distances separately for each population, therefore axes do not represent the same dimensions for each plot. Individual samples are represented by unfilled symbols, and population centroids for each time point are represented by filled symbols. Color represents feed regime, and shape indicates sample date. Centroids for each sampling date are connected in temporal order with solid lines to highlight compositional shifts over time.
