Figure 9
Prevalence and co-occurrence patterns of OTUs detected in spring 2018. (a) Prevalences of the 7 OTUs present in spring 2018 animals across all sampling periods (sampling sites considered together). (b) Co-occurrence matrix for the 7 OTUs calculated using all animals from all sampling periods and locations. + indicates that these OTUs occurred together in the same animal more than would be expected if they were randomly distributed with respect to each other, − indicates that the pair occurs less frequently than expected, and 0 indicates that the OTUs co-occur as much as would be expected assuming random distribution.
