Abstract

Over the past few years, the dynamics of power struggles between males and females and their conflicts over reproductive and social control have captured increasing attention from both the scientific community and society as a whole. This interplay between the sexes is of considerable significance and has emerged as a prominent research topic. In my thesis, I investigated the behavioural strategies that males use to build social relationships with females in a social mammal, the spotted hyena, where females have both high social control and high reproductive control. I analysed how males approach females and how females respond to the different approach styles. I found that male approaches can be characterised as casual, cautious, or sneaky, and that these styles may influence the likelihood of aggression in both males and females. Additionally, I found that these approach styles, combined with the life history traits of both sexes, play a role in shaping the overall outcome of male-female interactions. My thesis shows how different acts and signals could serve as indicators for male intentions and subsequent female responses, while also exploring how distinct approaches may explain the differences in male reproductive success.

Abstract (croatian)

Tijekom proteklih nekoliko godina, dinamika borbi za moć između mužjaka i ženki kao i njihovi sukobi oko reproduktivne i društvene kontrole zaokupili su sve veću pozornost i znanstvene zajednice i društva u cjelini. Ova međuigra između spolova je od velikog značaja te se je pojavila kao istaknuta tema istraživanja. U svom sam diplomskom radu istraživala strategije ponašanja koje mužjaci koriste za izgradnju društvenih odnosa sa ženkama kod pjegave hijene, društvenog sisavca gdje ženke imaju visoku društvenu i reproduktivnu kontrolu. Istražila sam kako mužjaci prilaze ženkama i kako ženke reagiraju na različite stilove prilaska. Otkrila sam da se prilasci mužjaka mogu okarakterizirati kao ležerni, oprezni ili prikradajući te da ti stilovi mogu utjecati na učestalost ispoljavanja agresije i kod mužjaka i kod ženki. Osim toga, otkrila sam da ti stilovi prilaska, u kombinaciji s osobnim karakteristikama kod oba spola, igraju ulogu u oblikovanju ukupnog ishoda tih muško-ženskih interakcija. Moj diplomski rad pokazuje kako različiti prilasci i signali mogu poslužiti kao pokazatelji namjere mužjaka i posljedičnih odgovora ženki, dok također istražuje kako različiti prilasci mogu objasniti razlike u muškom reproduktivnom uspjehu.
