487.与大多数其他长寿和社会一夫一妻制的鸟类一样，在海鸟中，额外的父系关系通常相当罕见。在这里，我们报告了小海雀Alle Alle的首次父系研究，这是一种每年只抚养一只幼崽的北极海鸟。利用三个高度多态性的微卫星标记确定亲缘关系。我们发现样本中的所有26只雏鸟都是其社会父母的真正遗传后代，其额外对父系父系频率的95%置信上限为10.88%。这种水平的额外父系关系与密切相关的普通乌里亚海鸠和布鲁涅希海鸠的频率没有显著差异。T.

487.Extra-pair paternity is typically rather infrequent in seabirds, as in most other long-lived and socially monogamous birds. Here we report the first paternity study of thelittle auk Alle alle, a high arctic seabird which raises only a single chick per year.Parentage was determined using three highly polymorphic microsatellite markers. Wefound that all 26 chicks in our sample were true genetic offspring of their social parents,with an upper 95% confidence limit of 10.88% for the frequency of extra-pair paternity.This level of extra-pair paternity is not significantly different from frequencies reportedfrom the closely related common Uria aalge and Bru¨nnich’s guillemots U. lomvia.J.
