From: Gut microbiome of century-old snail specimens stable across time in preservation
Non-metric multidimensional scaling analysis based on A year collected, for all snails from 1920 to 2018 (PERMANOVA: p-value < 0.001, R2 = 0.02), B location collected, for all snails from 1920 to 2018 (PERMANOVA: p-value < 0.001, R2 = 0.12), C short-term preservation treatment, for all snails from 2018 (PERMANOVA: p-value < 0.001, R2 = 0.20), and D location collected, for all snails from 2018 (PERMANOVA: p-value < 0.001, R.2 = 0.18). Each point represents one snail gut microbiome community. MRS refers to the Mountain Research Station location
