a
All alpha-diversity metrics were calculated across the University of Wisconsin—Milwaukee Recirculating Aquaculture System sites using the V6 16S rRNA gene sequence data set.
b
Data represent Shannon-Weaver diversity index (H’) values. Standard deviation (SD) values are indicated after the mean values.
c
Data represent Pielou’s evenness metric (J) values. Standard deviation (SD) values are indicated after the mean values.
d
The number of samples at each site is indicated.
e
Sample categories used in Kruskall-Wallis rank sum hypothesis testing are indicated.
