In species with pronounced male armaments, body and weapon size often determine success in agonistic interactions. However, the behavioural components of interactions also play a significant role in determining outcomes and individuals that win agonistic interactions may not be the ones that start contests. In this study, we used dyadic, intrasexual assays to characterize agonistic behaviours and determine whether body size and/or the propensity to start interactions influences contest outcome. ...

In species in which males signal competitive ability through secondary sexual traits, males with different levels of trait expression may adopt different reproductive tactics to maximize their reproductive success. In fission–fusion social systems, the most dominant males often roam widely in search of females in oestrus, and thus exhibit different patterns of sociability from subordinate males that utilize alternative reproductive tactics. Giraffes, Giraffa camelopardalis, are rare among mammal...

Maternal reproductive effort can be adjusted through the transfer of hormones into the eggs, where they influence embryo development, mediating short- and long-term maternal effects on offspring phenotype. While studies usually explore how females can increase their reproductive success through an allocation of yolk testosterone (T) under external environmental variability, it is less clear whether intrinsically driven interfemale differences in yolk T deposition may themselves predict female re...

Mate preference based on relatedness may evolve in response to costs and benefits of inbreeding avoidance. Whereas mating with closely related individuals can have negative fitness consequences due to inbreeding depression, it may simultaneously be favoured by inclusive fitness benefits. Variation in the fitness payoff shaped by benefits of inbreeding may even lead to preference for mating with kin. We investigated this hypothesis in the social spider Stegodyphus dumicola, a cooperative species ...

Male same-sex sexual behaviour (SSB), where males court or attempt to mate with other males, is common among animal taxa. Recent studies have examined its fitness costs and benefits in attempts to understand its evolutionary maintenance, but the evolutionary consequences of SSB are less commonly considered. One potential impact of SSB might be to facilitate the evolution of traits associated with less sexually dimorphic males, such as alternative reproductive tactics, by diverting costly aggress...
