Abstract

Urban life is associated with dietary shifts in opportunistic predators, such as raptors. This is presumably true in food-poor environments, such as drylands. We investigated this issue in little owls (Athene noctua) inhabiting an arid southern Tunisian area. Using pellet data, we found that coleopterans accounted for 69% of ingested food items. Controlling for prey availability, this coleopteran-based diet was more notable in the urban environment compared to rural areas. We suggest that habitat conditions in the urban areas have increased the catchability of nocturnal coleopterans which were then more exposed to predation by little owls than in rural areas.

北非干旱地区的小猫头鹰（Athene noctua）将食物转向夜间活动的甲虫

城市生活与机会性捕食者（如猛禽）的饮食变化有关。在食物匮乏的环境中，例如在干旱地区，情况大概也是如此。我们对栖息在突尼斯南部干旱地区的小猫头鹰（Athene noctua）进行了研究。通过颗粒数据，我们发现鞘翅目昆虫占摄入食物的 69%。在控制了猎物的可获得性后，城市环境中鞘翅目昆虫的食性比农村地区更为显著。我们认为，城市地区的栖息地条件增加了夜间鞘翅目昆虫的可捕获性，与农村地区相比，这些昆虫更容易被小猫头鹰捕食。

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.
