Risk allocation and competition in foraging groups: reversed effects of competition if group size varies under risk of predation.
Animals often feed more quickly when in larger groups. This group-size effect is often explained by safety advantages for groups but an alternative explanation is that animals feed faster in larger groups because of greater scramble competition for limited food. We show that predation risk enhances...
