In this study, we performed the first monitoring activities on one of the most endangered amphibians in Europe, the Sette Fratelli cave salamander . The data presented here are derived from two monitoring activities aiming to assess the status and abundance of four populations of . With the first monitoring, we surveyed the well-known population occurring within artificial springs during the period 2015-2018, providing monthly data on the number of active individuals. With the second monitoring performed during spring to early summer of 2022, we surveyed four populations at three time points (the one from artificial springs and three from forested areas) and we provided the first estimation of the populations' abundance. Furthermore, we analyzed for the first time the stomach contents from a population of only occurring in forested environments. With our study, we provided the first information on the abundance of different populations of , representing the starting point for future status assessments for this endangered species.
在本研究中，我们对欧洲最濒危的两栖动物之一——七兄弟洞螈开展了首次监测活动。此处呈现的数据源自两项监测活动，旨在评估四个种群的现状和数量。在首次监测中，我们于2015年至2018年期间对人工泉中著名的种群进行了调查，提供了活跃个体数量的月度数据。在2022年春季至初夏进行的第二次监测中，我们在三个时间点对四个种群（一个来自人工泉，三个来自林区）进行了调查，并首次估算了种群数量。此外，我们首次分析了仅在森林环境中出现的一个种群的胃内容物。通过我们的研究，我们首次提供了不同种群数量的信息，为该濒危物种未来的现状评估奠定了基础。
