Abstract

The feeding ecology of the Little Owl (Athene noctua) was studied in farmlands of southeast Poland, which is dominated by monocultural farms. 3065 prey dissected from pellets were collected at 13 pellet stations between 1999 and 2001 through 7 seasons in total. Mammals were found to dominate both in total number (54.3% of caught prey) and total biomass (93.0% of caught prey) while insects comprised 43.0% of the number, but only 1.1% of the prey biomass. However, the proportion of insects reached up to 62% in certain seasons. Coleopteran beetles dominated the insect fraction representing 98.3% of the number and 87.9% of the insect biomass. Our study also illustrated that in some seasons, the prey composition included taxa related to intensive agricultural management. The food composition of the Little Owls from the examined Polish sites is more similar to Eastern and Southern populations than to Northern and Western populations of Little Owls in Europe.

波兰东南部农田地区小猫头鹰 Athene noctua 的食物组成

在波兰东南部以单一种植农场为主的农田中，对小鸮（Athene noctua）的觅食生态进行了研究。在1999年至2001年的7个季节中，在13个食团站共收集了3065个食团上的猎物。结果发现，哺乳动物在总数量（占捕获猎物的 54.3%）和总生物量（占捕获猎物的 93.0%）方面均占优势，而昆虫占捕获猎物数量的 43.0%，但只占捕获猎物生物量的 1.1%。但在某些季节，昆虫的比例高达 62%。鞘翅目甲虫占昆虫总数的 98.3%，占昆虫生物量的 87.9%。我们的研究还表明，在某些季节，猎物组成包括与集约化农业管理有关的类群。波兰研究地点的小鸮的食物组成与欧洲东部和南部的小鸮种群更为相似，而与北部和西部的小鸮种群更为相似。

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.
