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:Effects of Extreme Weather on Reproductive Success in a Temperate-Breeding Songbird / Pipoly Ivett, Bókony Veronika, Seress Gábor, Szabó Krisztián, Liker András
Dátum:2013

Megjegyzések:The frequency of extreme meteorological events such as heat waves and rainstorms is predicted to increase withclimate change. However, there is still little information about how extreme weather influences reproduction inanimals. It may not only affect breeding success but might also alter offspring sex ratio if males and females aredifferentially sensitive to meteorological conditions during development. We investigated the relationship betweenmeteorological conditions and reproductive success over 6 years in a house sparrow population in central Europe.We found that hatching success increased with the number of extremely hot days (daily maximum >31?C) anddecreased with the number of extremely cold days (<16?C) during incubation, although the latter effect held only forclutches with relatively short incubation periods. Fledging success was unrelated to weather variables. However, thefrequency of extremely hot days had a negative effect on fledglings' body mass and tarsus length, although both ofthese traits were positively related to average temperature. Additionally, fledglings' body mass increased with thelength of period without rainfall before fledging. Male to female ratio among fledglings did not differ from 1:1 and didnot vary with weather variables. The magnitude of the effects of extreme meteorological events was usually small,although in some cases comparable to those of ecologically relevant predictors of reproductive success. Our resultsindicate that meteorological conditions have complex effects on breeding success, as the effects of extreme weathercan differ between different aspects of reproduction and also from the effects of overall meteorological conditions.
