Fecal glucocorticoid metabolites (fGCMs) (n = 1542 feces), in free-living banded mongooses (Mungos mungo) in northeastern Botswana (2008–2011), were modeled by group identity (1|group) and sampling event (1|event) as random effects in all models (omitted from table), and fixed effects: percentage fecal organic matter (org); soil macrofauna density (macro); recent rainfall (rain); access to concentrated anthropogenic food sources (anth); breeding status (breed); group size (size); and percent canopy cover (cc). We analyzed all subsets for model averaging, but present only the best models (\(\Delta \hbox {AIC}_c < 2\)) here
