NMDS ordinations based on Bray-Curtis dissimilarity scores for the gut bacterial communities of nine species of freshwater mussels (Alasmidonta triangulata, Cambarunio nebulosus, Venustaconcha trabalis, Hamiota altilis, Lampsilis virescens, Pseudodontoideus connasaugaensis, Ptychobranchus foremanianus, Margaritifera marrianae, and Theliderma cylindrica) preserved in ethanol for 2-9 years. The mussels were propagated in captivity from wild parents, and ordinations are shown based on the river of parental origin (A) and the year of sample preservation (B). The gut communities were analyzed in 2021, reflecting storage durations of 2 years (2019 samples), 4 years (2017), 5 years (2016), 6 years (2015), and 9 years (2012). There were significant differences between the gut microbial communities based on mussel species (PERMANOVA; p < 0.01, F = 1.816) but not between the rivers of parental origin and storage duration (p > 0.05) within the full statistical model.

Freshwater mussels are important indicators of the overall health of their environment but have suffered declines that have been attributed to factors such as habitat degradation, a loss of fish hosts, climate change, and excessive nutrient inputs. The loss of mussel biodiversity can negatively impact freshwater ecosystems such that understanding t...

... species was removed from the model to account for the low replicability of each species derived from the same river of parental origin and year of preservation, the gut bacterial communities between the rivers of parental origin were significantly different (p < 0.01, F = 1.843) and accounted for 30.0% of the variation in the gut bacterial community. The year of preservation also showed significant differences between bacterial communities (p < 0.05, F = 1.501) but accounted for only 14.7% of the sample variation ( Figure 3A,B). having much less significant effects. ...
