  • 22 November 2001
The variation in the acoustic structure of alarm calls appears to convey information about the level of response urgency in some species, while in others it seems to denote the type of predator.Expand

Selfish sentinels in cooperative mammals.
Like humans engaged in risky activities, group members of some animal societies take turns acting as sentinels. Explanations of the evolution of sentinel behavior have frequently relied on kinExpand

Intrasexual competition and sexual selection in cooperative mammals
In most animals, the sex that invests least in its offspring competes more intensely for access to the opposite sex and shows greater development of secondary sexual characters than the sex thatExpand

Acoustic sequences in non‐human animals: a tutorial review and prospectus
Animal acoustic communication often takes the form of complex sequences, made up of multiple distinct acoustic units. Apart from the well‐known example of birdsong, other animals such as insects,Expand

The information that receivers extract from alarm calls in suricates
Field observations and acoustic analyses have shown that suricate (Suricata suricatta) alarm calls vary in their acoustic structure depending on predator type. In this study, we tested whetherExpand

Predation, group size and mortality in a cooperative mongoose, Suricata suricatta.
1. In social mammals where group members cooperate to detect predators and raise young, members of small groups commonly show higher mortality or lower breeding success than members of large ones. ItExpand

Costs of cooperative behaviour in suricates (Suricata suricatta)
Functional interpretations of helping behaviour suggest that it has evolved because helpers increase their direct or indirect fitness by helping. However, recent critiques have suggested that helpingExpand

‘Nasty neighbours’ rather than ‘dear enemies’ in a social carnivore
  • C. Müller, M. Manser
  • Psychology, Medicine
  • Proceedings of the Royal Society B: Biological…
  • 7 April 2007
Territorial animals typically respond less aggressively to neighbours than to strangers. This ‘dear enemy effect’ has been explained by differing familiarity or by different threat levels posed byExpand

Cooperation, control, and concession in meerkat groups.
"Limited control" models of reproductive skew in cooperative societies suggest that the frequency of breeding by subordinates is determined by the outcome of power struggles with dominants. InExpand

Individual contributions to babysitting in a cooperative mongoose, Suricata suricatta
Evolutionary explanations of cooperative breeding based on kin selection have predicted that the individual contributions made by different helpers to rearing young should be correlated with theirExpand
