Intercourse impact

We expected that the chemical composition from anal gland secretions would differ between sexes. We discovered this kind of sex distinction, but just in adult individuals; outcome additionally present in mandrills ( Setchell et al., 2010). We unearthed that the anal gland secretions of adult female Alpine marmots had been reasonably abundant with cholestanol compared to adult male people, that has been likewise present in anogenital gland secretions of female giant pandas ( Yuan et al., 2004). The anal gland secretions of adult male Alpine marmots had been alternatively fairly abundant with pentadecanal, and also this ingredient has also been reported to be reasonably more abundant in male than in feminine adult giant pandas ( Yuan et al., 2004).

Our outcomes indicate that the chemical composition of anal gland fragrance might be properly used for sex recognition when you look at the Alpine marmot.

The capability of fragrance secretions to tell on intercourse is well documented both in eutherian animals (e.g. hyena, Crocuta crocuta: Drea et al., 2002; ring-tailed lemurs, Lemur catta: Hayes et al., 2004; Scordato et al., 2007; owl monkeys: MacDonald et al., 2008; Eurasian otters, Lutra lutra: Kean et al., 2011; brown bears, Ursus arctos: Rosell et al., 2011; giant pandas: Yuan et al., 2004) and monotremes ( e.g. short-beaked echidna, Tachyglossus aculeatus: Harris et al., 2012, 2014). Classically, intercourse recognition from olfactory cues is recommended to relax and play a part in intimate interactions such as for example mate location ( Alberts, 1992), mate attraction ( Haymann, 2006) and mate option ( Johansson & Jones, 2007).
