“…Male lacertid lizards, including those of all Podarcis species, have specialized epidermal glands on the underside of their hind legs that exude waxy secretions, which are deposited as scent‐marks in the environment when lizards move through the habitat (Mayer, Baeckens, & Van Damme, 2015). Over the last decade, extensive behavioural assays combined with studies of natural products chemistry have revealed that the lipophilic compounds in these waxy secretions are important for lizard communication (Heathcote, Bell, d'Ettorre, While, & Uller, 2014; Khannoon, El‐Gendy, & Hardege, 2011; MacGregor et al, 2017; Pruett et al, 2016; Zozaya, Higgie, Moritz, & Hoskin, 2019). While an individual chemical compound can mediate social interactions as varied as territorial behaviour, male rival assessment and mate choice (Kopena, Martín, López, & Herczeg, 2011; Martín & López, 2006, 2007; Martín, Moreira, & López, 2007; Wyatt, 2014), in most cases the chemical signals of lizards are composed of a species‐specific mixture of multiple lipophilic compounds (Martín & Lopéz, 2014, 2015; Mayerl et al, 2015).…”
