Do alternative reproductive tactics predict problem-solving performance in African striped mice?

In changing environments, animals face unexpected problems to solve. Not all individuals in a population are equally able solve new problems. It still remains unclear what factors (e.g. age and body condition) influence the propensity of problem solving. We investigated variation problem-solving performance among males following alternative reproductive tactics (ARTs). studied free-ranging African striped mouse (Rhabdomys pumilio). Adult male mice can employ 3 ARTs: (1) dominant group-living breeders, (2) philopatric living their natal group, (3) solitary-living roamers. ARTs reflect differences competitiveness, sociality physiology which could performance. tested total 48 2 years with two tasks: string-pulling task reach food door-opening nest. Since differ personality traits independent ARTs, we also measured activity, boldness exploration. addition, assessed association condition Problem solving was related interaction ARTs. The younger philopatrics had better food-extraction whereas older breeders were faster at task. Individual significant correlates performance: pro-active (i.e. more active explorative bolder) performed both tasks. Finally, not consistent between Our study provides evidence on abilities.
