Table 2 A Generalised Linear Model investigating the association between gut microbiome alpha diversity (Shannon diversity) and survival in the Seychelles warbler

From: Gut microbiome composition, not alpha diversity, is associated with survival in a natural vertebrate population

  1. Significant (Padj < 0.05) predictors are shown in bold; P values were corrected for multiple hypothesis testing using the Benjamini and Hochberg method- this was to control for the use of different alpha diversity metrics (results for other metrics are shown in Additional file 1: Table S4). Reference categories for categorical variables were as follows: adult (age class), female (sex) and 2017 (sample year). N = 264 samples/individuals were included in the analysis (226 individuals survived, 38 individuals died by the next breeding season)
