Helping as a signal: does removal of potential audiences alter helper behavior in the bell miner?
Despite many studies on the evolution of cooperative breeding and helping at the nest, relatively few have explored the possibility that helping functions as a signal to gain social advantage within groups (the ‘‘pay to stay’’ and ‘‘social prestige’’ hypotheses). One of the most promising candidates for such a signaling system is the cooperatively breeding bell miner, Manorina melanophrys. Larg...
متن کاملExperimental evidence for helper effects in a cooperatively breeding cichlid
Neolamprologus pulcher is a cooperatively breeding cichlid fish, in which helpers stay in their natal territory and help with brood care, territory defense, and maintenance. In this study we investigated helper effects by an experimental group size reduction in the field. After this manipulation, focal helpers in reduced groups tended to feed less, and small helpers visited the breeding shelter...
متن کاملMaternal Effects in Relation to Helper Presence in the Cooperatively Breeding Sociable Weaver
In egg laying species, breeding females may adjust the allocation of nutrients or other substances into eggs in order to maximise offspring or maternal fitness. Cooperatively breeding species offer a particularly interesting context in which to study maternal allocation because helpers create predictably improved conditions during offspring development. Some recent studies on cooperative specie...
متن کاملAntiparasite behavior
What do you think are the biggest challenges to the scientific community in the short/medium/ long term? I think we need to get out more. Science has become ghettoised. The pressures of the grant-publication-grant cycle are keeping people in their labs, talking to a very narrow range of people. Science is increasingly a disconnected and segregated activity. This situation has a lot of very nega...
متن کاملHelper Response to Experimentally Manipulated Predation Risk in the Cooperatively Breeding Cichlid Neolamprologus pulcher
BACKGROUND We manipulated predation risk in a field experiment with the cooperatively breeding cichlid Neolamprologus pulcher by releasing no predator, a medium- or a large-sized fish predator inside underwater cages enclosing two to three natural groups. We assessed whether helpers changed their helping behaviour, and whether within-group conflict changed, depending on these treatments, testin...
