- Аннотация: Acrocephaline warblers show a diverse range of mating systems including monogamy, polygamy and promiscuity. Extra-pair copulations (EPCs) have been documented in several reed warbler species. We determined frequencies of EPCs in local populations of two closely related, socially monogamous species: Blyth's reed warbler (Acrocephalus dumetorum) and the large-billed reed warbler (A. orinus). Data were collected in the Unzha river valley, Kostroma Region, Russia (May–July 2009) and in the Ghund river valley, Gorny Badakhshan Autonomous Region, Tajikistan (June–July 2012). Genetic analyses were performed on five microsatellite loci (136 samples from A. orinus [52 adults and 84 chicks] and 140 samples from A. dumetorum [54 adult and 86 chicks]). We documented extra-pair offspring in both populations; however, Fisher’s exact tests revealed significant differences in EPC rate between the two species (P<0.05). The rate of EPC was significantly higher in A. dumetorum than in A. orinus. This result is consistent with low genetic diversity observed in the local population of A. orinus. The study was supported by the Russian Fund for Basic Research and the Rufford Small Grants Foundation.
