摘要

在保加利亚南部Strandzha山脉以森林和灌木为主的狩猎区，从516个猎物标本中确定了普通仓鸮的饮食。以鼩鼱(52.9%，26.7%)和啮齿动物(42.1%，71.5%)为主。其中，白齿鼩(Criocidura sp.， N占45.3%，B占21.4%)是数量最多的猎物属。由于条纹田鼠黑线姬鼠(A. agrarius, B . 12.2%)对食物生物量的大量捕食，黑线姬鼠(15.7% N, 29% B)对食物生物量的贡献最大。在保加利亚南部大多数仓鸮猎区，随着森林栖息地(森林和灌丛覆盖面积超过25%)的比例增加，森林物种(黑线姬鼠，Sorex sp.和睡鼠liridae)的比例也在增加。

Effects of a forest landscape on the prey composition of the Common Barn-owl Tyto alba in southern Bulgaria

The diet of the Common Barn-owl in a forest- and shrub-dominated hunting area in the Strandzha Mountains, southern Bulgaria, was identified from 516 prey specimens. Shrews (52.9% by number, 26.7% by biomass) and rodents (42.1% N, 71.5% B) were prevalent. Among them, White-toothed shrews, Criocidura sp., (45.3% N, 21.4% B) was the most numerous prey genus. Mice, Apodemus sp., (15.7% N, 29% B) contributed with the largest share to the food biomass due to high predation of Striped field mice, A. agrarius, (12.2% B). The proportions of forest species in diet (Apodemus sp, Sorex sp., and dormice liridae) increased with the higher proportion of forest habitats (forests and shrublands cover more than 25% of the area) in most Barn Owl hunting territories in southern Bulgaria.

期刊介绍： Travaux du Muséum National d’Histoire Naturelle "Grigore Antipa" (The Journal of "Grigore Antipa" National Museum of Natural History) is an international, open access, peer-reviewed journal devoted to zoological research that is published biannually by the "Grigore Antipa" National Museum of Natural History from Bucharest (Romania). It publishes original research or review articles dealing with all aspects of general zoology (taxonomy, systematics, evolutionism, faunistics, zoogeography, palaeozoology, animal ecology, invasive species of animals, parasitism, biodiversity conservation). Also, some book reviews, anniversaries and obituaries of some personalities of science world can be accepted to be published in this journal. In the present, the only language accepted for this journal is English. The scope of the journal is to publish, disseminate and provide open access to the results of the original studies made in different zoological fields, in Romania and worldwide. Every submitted manuscript is subject to peer-review, being reviewed by at least two peers qualified to evaluate it. Distinguished authorities form the international advisory board which guarantees the high scientific profile of the journal.
