Long-distance dispersal is asymmetrical with respect to age, sex and breeding latitude in a long-lived monogamous bird

Although relatively rare, long-distance dispersal significantly impacts population persistence by facilitating range expansion, range shifts, and genetic exchange. For individuals dispersing northwards, it may be a suitable adaptation strategy to escape negative effects of climate change on their original breeding sites. In this study, we constructed a joint live encounter – dead recovery model under a Bayesian multistate framework to quantify long-distance dispersal between the Barents Sea, Baltic Sea, and North Sea subpopulations of the Russia/Germany & Netherlands flyway population of barnacle goose (Branta leucopsis), using long-term mark-recapture data of 22,413 individuals ringed between 1995 – 2023. Long-distance dispersal was strongly biased by age-, sex- and direction. Natal dispersal predominantly occurred in northward direction with 23.9% of juvenile males and 8.6% of juvenile females estimated to transition annually from the North Sea to the Barents Sea subpopulation.

长距离扩散虽相对罕见，却可通过促进种群分布扩张、分布区转移与基因交流，对种群存续产生显著影响。对于向北扩散的个体来说，该策略或是规避气候变化对其原有繁殖地造成负面影响的适宜适应方案。

本研究基于贝叶斯多状态框架，构建联合存活重捕与死亡回收模型，借助1995年至2023年间环志的22413只个体的长期标记重捕（mark-recapture）数据，量化了俄罗斯/德国&荷兰迁徙路线种群的白颊黑雁（Branta leucopsis）在巴伦支海、波罗的海与北海亚种群间的长距离扩散格局。长距离扩散显著受到年龄、性别与扩散方向的偏倚调控。出生扩散（natal dispersal）主要以向北方向为主，据估算，每年有23.9%的雄性幼鸟与8.6%的雌性幼鸟会从北海亚种群扩散至巴伦支海亚种群。
