Abstract
Recently, the Taiga Bean Goose Anser f. fabalis breeding population of Southern Lapland, Sweden, was shown to use a network of local sites during their summer wing moult. We used microsatellite markers to identify individual geese from DNA in shed feathers collected in 2016–2020 on six sites, enabling us to identify 168 unique individuals from 178 fully genotyped feathers. Nine individuals were represented multiple times among the collected feathers. All controls of identified individuals were made on the original site, never on an alternative site. Our results suggest a significant level of site fidelity and, thus, the need to provide a stable, low-disturbance network of moulting sites for the Southern Lapland sub-population of this endangered taxon.
最近,瑞典南拉普兰的泰加豆雁(Anser f. fabalis)繁殖种群在夏季换羽期间使用了一个由当地地点组成的网络。我们使用微卫星标记从2016-2020年在6个地点收集的脱落羽毛中的DNA来识别鹅个体,使我们能够从178根完全基因分型的羽毛中识别出168个独特个体。在收集到的羽毛中,有 9 个个体多次出现。所有已识别个体的对照都是在原始地点进行的,从未在其他地点进行过对照。我们的研究结果表明,这种濒危类群对地点的忠诚度很高,因此有必要为拉普兰南部亚群提供一个稳定、低干扰的换羽地点网络。
