摘      要：Urban areas differ from natural habitats in several environmental features that influence the characteristics of animals living *** example,birds often start breeding seasonally earlier and fledge fewer offspring per brood in cities than in natural ***,longer breeding seasons in cities may increase the frequency of double-brooding in urban compared with nonurban populations,thus potentially increasing urban birds’annual reproductive output and resulting in lower habitat difference in reproductive success than estimated by studies focusing on first clutches *** this study,we investigated 2 urban and 2 forests great tit Parus major populations from 2013 to *** compared the probability of double-brooding and the total number of annually fledged chicks per female between urban and forest habitats,while controlling for the effects of potentially confounding *** was a trend for a higher probability of double-brooding in urban(44%of females)than in forest populations(36%),although this was not consistent between the 2 urban *** produced significantly fewer fledglings annually in the cities than in the forest sites,and this difference was present both within single-and double-brooded ***,double-brooded urban females produced a similar number of fledglings per season as single-brooded forest *** results indicate that double-brooding increases the reproductive success of female great tits in both habitats,but urban females cannot effectively compensate in this way for their lower reproductive output per ***,other mechanisms like increased post-fledging survival can mitigate habitat differences in reproductive success.
