摘要

在此，我们首次对圣马力诺共和国的意大利洞螈（Speleomantes italicus）外种群的猎物消耗情况进行了研究。我们使用无害的冲洗胃部技术，旨在提供关于所研究种群的饮食和个体专业化程度的第一手数据。我们进行了两次夜间调查（一次在 2022 年秋季，一次在 2023 年春季），在林区和干燥的墙壁上伺机搜寻蝾螈。我们对捕获的蝾螈进行了性别鉴定、称重、拍照、测量和洗胃。总体而言，我们检查了 67 个个体的胃内容物，确认了 1 018 种猎物，分属 28 个不同的猎物类别。受检种群主要由通食个体组成，没有观察到蝾螈之间在捕食猎物的数量和多样性方面存在差异。与在其他蝾螈物种中观察到的情况不同，飞行猎物对调查种群的食物贡献很小。我们的研究首次提供了圣马力诺共和国Speleomantes italicus的饮食信息，为今后评估该特定种群的饮食习惯提供了起点。

First data on the consumed prey by Speleomantes italicus from the Republic of San Marino

We here present the first study on the consumed prey by an epigean population of the Italian cave salamander (Speleomantes italicus) from the Republic of San Marino. Using the harmless technique of stomach flushing, we aimed to provide the first data on the diet and on the degree of individual specialization that characterizes the studied population. We performed two-night surveys (one in autumn 2022 and one in spring 2023) in which we opportunistically searched for salamanders in forested areas and dry walls. Captured salamanders were sexed, weighed, photographed, measured and stomach flushed. Overall, we inspected the stomach contents of 67 individuals, recognizing 1,018 prey items belonging to 28 different prey categories. The examined population was mainly composed by generalist individuals, and no differences in number and diversity of prey consumed were observed among salamanders. Contrarily to what has been observed in other Speleomantes species, flying prey provided a minor contribution to the diet of the investigated population. Our study produced the first information on the diet of Speleomantes italicus from the Republic of San Marino, representing the starting point for future assessments on the dietary habits of this specific population.

期刊介绍： Acta Herpetologica, a journal open to academics all over the world, offers itself as a new site for the presentation and discussion of the most recent results in the field of research on Amphibians and Reptiles, both living and extinct. The official journal of the Societas Herpetologica Italica (S.H.I.), Acta Herpetologica publishes original works – extended articles, short notes and book reviews – mostly in English, dealing with the biology and diversity of Amphibians and Reptiles.
