摘要

通过分析 2015/16 年繁殖季节在南极半岛天堂湾收集的 20 个颗粒，研究了南极雉的食物。鱼类是最常见和最重要的猎物，其次是多毛类。在鱼类中，只有底栖底栖生物在食谱中占有一定比例。Harpagifer antarcticus是最常见的猎物，其次是Notothenia coriiceps，在数量和质量上都是最重要的。研究结果与南设得兰群岛和南极半岛其他地方报告的鲣鸟食谱进行了比较，并从地理意义、繁殖产量和种群趋势等方面进行了讨论。

Fish in the diet of the Antarctic Shag Leucocarbo bransfieldensis breeding at Paradise Bay, Antarctic Peninsula

The diet of the Antarctic shags was investigated at Paradise Bay, Antarctic Peninsula, by the analysis of 20 pellets collected during the 2015/16 breeding season. Fish were the most frequent and important prey, accompanied by Polychaetes. Amongst fish, only benthic-demersal species were represented in the diet. Harpagifer antarcticus, followed by Notothenia coriiceps, was the most frequent prey and the most important by number and mass. The results are compared with the diet reported for this shag at other localities of the South Shetland Islands and of the Antarctic Peninsula and discussed in terms of geographical significance, breeding output, and population trend.

期刊介绍： Polar Biology publishes Original Papers, Reviews, and Short Notes and is the focal point for biologists working in polar regions. It is also of interest to scientists working in biology in general, ecology and physiology, as well as in oceanography and climatology related to polar life. Polar Biology presents results of studies in plants, animals, and micro-organisms of marine, limnic and terrestrial habitats in polar and subpolar regions of both hemispheres.
