Studies highlight the effects of glyphosate and glyphosate-based herbicides on the hypothalamic-pituitary-adrenal (HPA) axis of vertebrates. Nevertheless, they utilised dosages higher than toxicological reference values (TRVs) suggested by the European Food Safety Authority (EFSA), formulations of glyphosate, not allowing for clear distinctions of glyphosate's effect itself, and blood samples, a technique inappropriate for small animals and for assessing long-term chronic effects. Here we tackled those caveats by analyzing faecal corticosterone metabolites (FCMs) of the wall lizard Podarcis bocagei to detect glyphosate-induced effects on the HPA axis. This species provides a promising animal model as reptiles are prevalent in agricultural fields treated with herbicides, reptile-specific TRVs are lacking, and only five studies have validated immunoassays for measuring FCMs in reptiles. We validated the 5α-pregnane-3ß,11ß,21-triol-20-one enzyme immunoassay. We detected a moderate increase in FCM levels during the exposure phase, while exposed animals of both sexes displayed an altered mass-depended FCM profile.
