“…For instance, Ouyang et al (2014) found in great tits that similarity in baseline CORT levels between pair members increased with the years of partnership and could potentially guarantee bond stability or, alternatively, could be the result from breeding in the same territory. Third, partners may mutually adjust their hormone profiles to each other to coordinate reproductive activities (Gabriel and Black 2012;Hirschenhauser et al 1999) as shown in convict cichlid, Amatitlania siquia, in which breeding partners increase spawning size and their fitness by adjusting their behaviour (Laubu et al 2016) and 11-ketestosterone levels to each other, a hormone which is involved in the gametogenesis and spawning behaviour of several fish species (Schweitzer et al 2017). Because our results are correlative, we are not able to distinguish between these three hypotheses (assortative pairing, shared environment or post-pairing adjustment).…”

“…For instance, in greylag geese (Anser anser) and great tits (Parus major), partners showing similar testosterone and corticosterone profiles (and personalities in tits) during nesting care and throughout the year are less likely to divorce and achieve a higher reproductive success (Both et al 2005;Hirschenhauser et al 1999;Ouyang et al 2014;Weiss et al 2010). Inversely, in convict cichlids, Amatitlania siquid, partners with dissimilar glucocorticoid (cortisol) levels produced more eggs than partners with similar glucocorticoid levels (Schweitzer et al 2017).…”

“…Increasingly, it is recognized that behavioural and hormonal compatibility between partners plays a role in reproductive success (Both et al 2005;Burtka and Grindstaff 2015;Gabriel and Black 2012;Hirschenhauser 2012;Ouyang et al 2014;Schuett et al 2011a;Schweitzer et al 2017;Spoon et al 2006). Given that CORT is essential in the regulation of behaviours associated to reproduction (Love et al 2014), including incubation behaviour (Schoenle et al 2017;Thierry et al 2013) and offspring feeding rate (Almasi et al 2008;Ouyang et al 2013a), we investigated the similarity of baseline and stress-induced CORT levels between the breeding partners of barn owls (Tyto alba) and how similarity or dissimilarity is related to reproductive success.…”

In biparental species, reproductive success depends not only on the quality of the parents, the care they each provide and many environmental factors such as territory quality and food availability, but also on the ability of the parents to collaborate and divide reproductive tasks.Because hormones, such as corticosterone (CORT), modulate physiological and behavioural functions that are associated to reproductive success, hormonal compatibility between pair members is likely to have consequences on reproductive success. Here, we investigated in the barn owl (Tyto alba) whether baseline and stress-induced CORT levels are correlated between breeding partners and whether this correlation is associated to fitness parameters (i.e., clutch size, offspring number and body mass). We found that the combination of CORT levels in the two partners predicts reproductive parameters. Pairs with similar baseline CORT levels during incubation produced more fledglings than pairs with dissimilar baseline CORT levels. On the other hand, pairs showing dissimilar stress-induced CORT responses during the period of offspring rearing produced more fledglings than pairs with similar stress-induced responses. Offspring body mass was associated only with maternal (baseline and stress-induced) CORT levels and depended on the context with baseline CORT being potentially adjusted to environmental conditions but also to the energetic demand of reproduction. Hence, to produce large broods good quality mothers might increase their baseline CORT to meet the energetic demand of the brood, while mothers in unfavourable habitats may have smaller broods but still need to increase baseline CORT to cope with the environmental challenges. Taken together, the results show that the association between parental CORT levels and reproductive success are context-dependent and rely on the combination of parental CORT levels. Assuming that CORT levels reflect investment in parental care, our study suggests that parents coordinate their reproductive activities in a complex way to ensure a high reproductive success.

“…Indeed, reproductive success has been found to vary in relation to pair behavioural composition in various taxa (e.g. Laubu, Dechaume‐Moncharmont, Motreuil, & Schweitzer, ; Schuett et al., ; Schweitzer et al., ). Also in our study species, the great tit, the highest feeding rates, number of recruits and fledgling condition were produced by pairs with similar personality types (Both et al., ; Mutzel et al., ; see also Johnson et al., ).…”

“…The influence, however, of the mate's personality type on egg hormone deposition of his female is presently unknown. At the proximate level, female assessment of, or response to her partner's behaviour could impact her own behaviour and physiology, and in turn influence egg hormone deposition (Ouyang, van Oers, Quetting, & Hau, 2014;Schweitzer et al, 2017;von Engelhardt & Groothuis, 2011).…”

Maternal egg hormones in the mating context: The effect of pair personality

et al. 2017

Abstract1. Animal personality traits emerge developmentally from the interaction of genetic and early environmental factors. Maternal hormones, such as androgens (testosterone, T and androstenedione, A4), transferred to embryos and egg yolks may simultaneously organize multiple behavioural and physiological traits. Although previous studies demonstrated an association between the mother's personality and yolk androgen levels, the independent effects of the male partner's personality and pair combination remains unknown.2. We test this association using an ecological model species for personality research, the great tit (Parus major) using multiple approaches: (1) a wild population, (2) a randomly mated captive population and (3) an experimental study with (dis)assortatively mated pairs from lines selected for fast exploration/boldness or slow exploration/shyness.3. Egg androgen concentrations were associated with variation in female personality traits, and the experimental data suggested that this is independent of male personality: Experimental females from the slow-shy line tended to have higher egg T concentrations than females from the fast-bold line, with no effect of male personality. Shy females from the wild population had higher egg A4 concentration than bold females. However, in the correlative data yolk hormones were linked with male personality, as well as the interaction between female and male traits: Male handling responsiveness correlated negatively with egg A4 concentration in wild birds. In randomly mated birds, pairs that were mated assortatively for personality had lower egg T concentrations than disassortatively mated pairs.4. Given that egg androgens are known mediators of avian personality, our results suggest that maternal hormones might contribute to the heritability of personality, may be sensitive to the social context of mating, and act as key drivers of individual differences.
