摘要

摘要通过分析2008-2010年和2016-2017年夏季收集的157个反刍颗粒，对阿根廷巴塔哥尼亚vinter湖的帝王沙鱼(Phalacrocorax atriceps)的饮食进行了调查。在整个研究期间，本地鱼类是主要的猎物，只有少数腹足类(2010年)和鞘翅类(2009年和2016年)。我们的研究结果与先前报道的在温特湖和其他地点繁殖的帝王长尾龟有明显的不同。讨论了研究结果与整个研究期间在温特湖观察到的长毛象种群下降的关系。

The Diet of the Imperial Shag Phalacrocorax atriceps at Vintter Lake, Patagonia, Argentina

Abstract. The diet of the Imperial Shag (Phalacrocorax atriceps) at Vintter Lake, Patagonia, Argentina, was investigated through analysis of 157 regurgitate pellets collected during the summer seasons of 2008–2010 and 2016–2017. The native fish Galaxias platei was the main prey throughout the study period, accompanied only by a few gastropod species (2010) and coleopterans (2009 and 2016). Our results markedly differ from those previously reported for Imperial shags breeding at Vintter Lake and other sites. The results are discussed in relation to the population decline observed in shags at Vintter Lake throughout the study period.
