Partitioning aggression.
Human Nature: Nasty or Nice? Have aggression and violence been ramped up in human evolution or dialed down? This sounds like a question that empirical research might have settled long ago, but it remains strangely contentious. In PNAS, Richard Wrangham (1) proposes that debates persist because too many evolutionary anthropologists mistakenly conceive of aggression as unitary and that a well-est...
متن کاملInterspecific Aggression and Habitat Partitioning in Garter Snakes
Defense of a limited resource, such as space or food, has recently been discovered in snakes and has been widely documented in lizards. Garter snakes (Thamnophis spp.) are historically considered generalist predators such that food is not a limiting resource. However, in this study we show that the common garter snake (Thamnophis sirtalis) and the aquatic garter snake (Thamnophis atratus) show ...

In cooperatively breeding species, helpers can alleviate reproductive constraints by assuming the role of primary carers to first-born young, liberating breeders to invest in subsequent broods. However, evidence on how first-born young are transferred to helpers is currently lacking. We propose that breeder-offspring aggression might facilitate inter-brood division and test this idea using data...
