  1. Euclidean distances were calculated based on either CLR or PhILR transformed Amplicon Sequencing Variant (ASV) abundances. Significant predictors (P < 0.05) are shown in bold. Analyses included 116 juvenile individuals (17 died, 99 survived) and 148 adults (21 died, 127 survived), respectively
