From: Volatiles of symbiotic bacterial origin explain ectoparasitism and fledging success of hoopoes
Alpha diversity of the bacterial communities (Shannon and Faith’s phylogenetic diversity (PD) indexes) and of volatile profiles (Shannon index) of samples collected in experimental (old nest material from previous reproduction was autoclaved and used to fill new nest boxes before reproduction started) and control nests (old nest material from previous reproduction was directly used to fill new nest boxes). Analysed samples included volatiles from nest environment (days four and 15 after hatching), and from female (Day 4 after hatching) and nestling (days 8 and 19 after hatching) uropygial secretions, and bacterial communities from the nest material (days four and 15 after hatching) and from the secretion of females and nestlings. Values are means ± 95% CI
