摘要

摘要：我们研究了2016年5月下旬至6月初在日本北海道特乌里岛附近夜间海上集会中捕获的30只古斑夜蛾的繁殖地发育、性别比和形态特征。分子性别鉴定表明，其中12只为雄性，18只为雌性。雄性（58%）和雌性（56%）的带育婴斑（繁殖状态的指标）的海雀比例相似。繁殖海雀比非繁殖海雀重。雄性比雌性有更深的喙和更长的头，但它们的重量、翅膀、秆、跗骨、喙宽度和头骨宽度相似。

Breeding Status and Sex Ratio of Ancient Murrelets Captured in the Nocturnal At-Sea Congregation Off Teuri Island, Japan

Abstract We examined brood patch development, sex ratios, and morphological traits of 30 Ancient Murrelets Synthliboramphus antiquus captured from the nocturnal at-sea congregation off Teuri Island, Hokkaido, Japan during late May to early June 2016. Molecular sexing determined that 12 of the murrelets were males and 18 were females. The proportions of murrelets with brood patches (an indicator of breeding status) were similar for males (58%) and females (56%). Breeding murrelets were heavier than non-breeding murrelets. Males had deeper bills and longer heads than females, but their weights, wings, culmens, tarsi, bill widths, and skull widths were similar.
