| الوصف: | International audience ; To maximize their fitness, individuals of one sex can display discrete reproductivephenotypes, called alternative reproductive tactics (ARTs). Individuals followingARTs show behavioural variation, which might result in differences in energyintake and expenditure. However, few studies have compared activity budgets andnon-sexual behaviour of individuals following ARTs in nature. We studied maleAfrican striped mice Rhabdomys pumilio, which can follow three ARTs: (1) breedingmale of a group of females; (2) philopatrics remaining in their natal group; or(3) solitary living roamers. We predicted that each tactic is characterized by itsspecific activity budget, representing alternative energy trade-offs. We conductedfocal animal observations on 70 males following ARTs. Roamers had higher travellingrates than philopatrics, and breeders had larger daily range sizes compared tophilopatrics but not roamers. Philopatrics had higher foraging rates than breedersand showed more socio-positive behaviour than roamers. Breeders and philopatricswere in their nest more often than roamers, potentially engaging in social interactionswith other group members. Roamers were chased off more often than breeders,but the three tactics did not differ concerning rates of socio-negativebehaviour. Overall, philopatrics allocated their time towards behaviours that wouldincrease body mass and survival probability, which could improve the probabilityto switch to a tactic of higher reproductive success. In contrast, breeders and roamersallocated their time towards behaviours that would increase their chances tomate. In conclusion, following ARTs results in contrasting activity budgets thatreflect the differences in reproductive behaviours observed between tactics. |
