Female relationships across mammals range from highly supportive to intensively aggressive, often within the same species. While differences in the structure of female relationships may have played a major role in the evolution of mammalian sociality (Lukas & Clutton-Brock 2013), only few studies have investigated why and how female interactions differ across species. In this presentation, I will show that competition between females is frequently as intense as what has been reported for males (Lukas & Clutton-Brock 2014), and that variation in the intensity of female competition is linked to female reproductive investment. Finally, I will discuss how competition influences cooperation between females (MacLeod & Lukas 2014).
