摘要

蝙蝠是为数不多的以蜘蛛为食的蝙蝠之一。为了研究这种类型的猎物的重要性，我们使用扩增子元条形码分析了该物种在伊比利亚半岛5个种群的饮食，以便在物种水平上描述其组成，并分析其在半岛内的地理变异性。共鉴定出11个节肢动物目138种猎物。其中，在106只被研究的蝙蝠中，有82只吞食了45种蜘蛛，其中大部分是球形织网行会的蜘蛛，与每个种群和季节的采样相对应。此外，鳞翅目和双翅目动物在每个群体中也有消耗。在后者中，稳定的苍蝇(Stomoxys calcitrans)在两个群体中尤为重要，这表明m。Emarginatus也可以机会性地利用不同的资源或觅食地，如牛棚，这影响了它的饮食组成，也影响了猎物的普通水平。

The Diet of the Notch-Eared Bat (Myotis emarginatus) across the Iberian Peninsula analysed by Amplicon Metabarcoding

Myotis emarginatus is one of the few bats known to feed mostly on spiders. In order to study the importance of this type of prey, we analysed the species’ diet in five colonies across the Iberian Peninsula using amplicon metabarcoding in order to describe its composition at the species level, and analyse its geographic variability within the peninsula. We identified 138 prey species, belonging to 11 different arthropod orders. Among them, 45 species of spiders were identified, mostly of the orb-web building guild, as consumed by 82 out of 106 studied bats, corresponding to every colony and season sampled. Besides, lepidopterans and dipterans were also consumed in every colony. Among the latter, the stable fly Stomoxys calcitrans was especially important in two of the colonies, showing thatM. emarginatus can also opportunistically exploit different resources or foraging grounds, such as cattle sheds, which affects the composition of its diet also at ordinal level of prey.

期刊介绍： Hystrix the Italian Journal of Mammalogy accepts papers on original research in basic and applied mammalogy on fossil and living mammals. The Journal is published both in paper and electronic "online first" format. Manuscripts can be published as full papers or short notes, as well as reviews on methods or theoretical issues related to mammals. Commentaries can also be occasionally accepted, under the approval by the Editor in Chief. Investigations of local or regional interest, new data about species distribution and range extensions or confirmatory research can be considered only when they have significant implications. Such studies should preferably be submitted as short notes. Manuscripts bearing only a local interest will not be accepted. Full papers have no limits in length as well as in figure and table number and are abstracted in English. Authors are encouraged to add supplemental material in form of colour figures, original datasets and/or computer program source code. Supplemental material and colour figures will appear only on the electronic edition. Short notes must be about 16000 characters long (including title, author names and affiliations, abstract and references), and do not include supplemental material. They are abstracted in English. Proceedings of symposia, meetings and/or workshops, and technical reports can be published as special supplements to regular issues, under the approval by the Editor in Chief and the Associate Editors. There are no page charges.
