^aRetention indices (RI) are given for compounds detected on Porapak samples.

^bAverage standard error of the difference, P-value and degrees of freedom (DF) derived from linear mixed models, which were fitted using the method of residual maximum likelihood.

^cNumber of samples in each group (number of individuals in brackets): Before n = 6 (6), During (−) n = 3 (3), During (+) n = 3 (3), After n = 6 (6), (Empty bag) Control n = 6.

^dFull matrices of SEDs including results of pairwise comparisons made per compound are provided in Supplementary Table S1.
