title: Data from: Macroevolutionary evidence suggests trait-dependent coevolution between behaviour and life-history

description: Species with fast life-histories typically prioritize current over future
 reproductive events, compared to species with slow life-histories. These
 species therefore require greater energetic input into reproduction, but
 also likely have less time to realize their reproductive potential. Hence,
 behaviours that increase access to both resources and mating
 opportunities, at a cost of increased mortality risk, are thought to
 coevolve with the pace of life-history. However, whether this prediction
 holds across species remains untested under standardized conditions. Here,
 we test how risky behaviours, which facilitate access to resources and
 mating opportunities (i.e. activity, boldness and aggression), along with
 metabolic rate, coevolve with the pace of life-history across 20 species
 of killifish, which present remarkable divergences in the pace of
 life-history. We found a positive association between the pace of
 life-history and aggression, but not with other behavioural traits or
 metabolic rate. Aggression is linked to interference competition, and in
 killifishes is often employed to secure mates, while activity and boldness
 are more relevant to exploit energetic resources. Our results suggest that
 the trade-off between current and future reproduction plays a more
 prominent role in shaping mating behaviour, while behaviours related to
 energy acquisition may be influenced by ecological factors.
