Abstract

Background: Yellow-legged gulls (Larus michahellis), commonly found in Istanbul and their surroundings, have a monomorphic plumage, like other gull species. For this reason, sex determination cannot be made externally. In this study, a total of 60 adult Yellow-legged gulls, 33 males, and 27 females, collected from the coastal areas of Istanbul, were examined. Discriminating functions were developed to classify males and females using birds that were previously sexed by DNA analysis and abdominal dissection.

Results: Head length and bill depth were selected to build the discriminant function by the stepwise analysis. The function classified male gulls with an accuracy of 97.0% and females with an accuracy of 92.6%. Head length alone is the most accurate predictor in terms of the percentage of correct sex determination (90.9% for males, 92.6% for females).

Conclusions: Functions that can easily determine sexual dimorphism for the population of Larus michahellis gulls around Istanbul have been put forward for the first time.

伊斯坦布尔附近黄腿鸥(Larus michahellis)形态测量的性别测定。

背景:黄腿海鸥(Larus michahellis)，常见于伊斯坦布尔及其周边地区，像其他海鸥物种一样，有一种单态羽毛。因此，性别决定不能由外部决定。在这项研究中，共检查了从伊斯坦布尔沿海地区收集的60只成年黄腿鸥，其中33只雄性和27只雌性。利用先前通过DNA分析和腹部解剖确定性别的鸟类，开发了区分雌雄的功能。结果:通过逐步分析，选择头长和喙深作为判别函数。该功能对雄性海鸥的分类准确率为97.0%，对雌性海鸥的分类准确率为92.6%。就正确的性别判断百分比而言，仅头长是最准确的预测因子(男性90.9%，女性92.6%)。结论:首次提出了伊斯坦布尔地区michahellis鸥种群性别二型性判别功能。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
