Megjegyzések:Individual variation in the propensity to express innovative behaviors is increasingly recognized as ecologically and evolutionarysignificant. A growing number of studies show that more innovative individuals can realize higher breeding success, indicating thatinnovativeness may be important in mating decisions. Here we investigated whether male and female performance in innovative problem-solving tasks is linked to sexual selection via extra-pair mating behavior. We observed the problem-solving success of great tit(Parus major) pairs in 2 tasks at the nest, and related it to the occurrence of extra-pair paternity (EPP) in their broods. In a food-acquisitiontask, we found no difference in EPP among pairs in which the male solved, pairs in which the female solved, and unsuccessfulpairs. In an obstacle-removal task that was solved almost exclusively by females, EPP was more frequent in broods of solver femalesthan in broods of unsuccessful females. These results do not support the hypothesis that the social male's innovativeness influencesthe female's extra-pair mating behavior. Instead, they suggest that the female's infidelity covaries positively with her innovativeness.Furthermore, EPP was related to both parents' neophobia such that pairs of highly neophobic individuals were less likely to have EPPthan pairs that contained at least one individual with low neophobia. These findings indicate that promiscuity is associated with certainbehavioral phenotypes, suggesting that both innovativeness and novelty seeking may facilitate the investment into and/or the exposureto extra-pair mating attempts.

Cím:Kinship and aggression: do house sparrows spare their relatives? / Tóth Zoltán, Bókony Veronika, Lendvai Ádám Z., Szabó Krisztián, Pénzes Zsolt, Liker András
Dátum:2009

Megjegyzések:Kin-selection theory predicts that relatedness may reduce the level of aggression among competing group members, leading to indirect fitness benefits for kin-favoring individuals. To test this hypothesis, we investigated whether relatedness affects aggressive behavior during social activities in captive house sparrow (Passer domesticus) flocks. We found that sparrows did not reduce their aggression towards kin, as neither the frequency nor the intensity of fights differed between close kin and unrelated flock-mates. Fighting success was also unrelated to kinship and the presence of relatives in the flock did not influence the birds' dominance rank. These results suggest that the pay-offs of reduced aggression towards kin may be low in non-breeding flocks of sparrows, e.g. due to competition among relatives as predicted by a recent refinement of kin-selection theory. Our findings indicate that the significance of kin selection may be restricted in some social systems such as winter aggregations of birds.
