Paper abstract bibtex 1 download We report on an introduced population of Italian Cave Salamander (Speleomantes italicus) that has been living in an abandoned quarry of the Solling area, Germany, within a beech forest near the town of Holzminden, since at least 2013. DNA sequences of the mitochondrial genes for 16S rRNA and cytochrome b confirm these specimens being genetically assignable to S. italicus, without genetic differentiation from populations of the native range. Nine individuals studied for infection by chytrid fungi by quantitative PCR tested all negative, both for Bd and Bsal. Up to 18 specimens per night were seen, and small juveniles (35 mm total length) observed from 2015–2020, suggesting continued successful reproduction. To understand the origin of this introduced Speleomantes population, it is relevant to consider the existence of an animal trade business in Holzminden until 1977 that imported, among many other amphibians and reptiles, Speleomantes italicus as early as 1914; furthermore, the same family business also exploited up to three quarries from 1946 to 1956 in the same area, although we could not verify whether this includes the one currently populated by Speleomantes. Although no proof exists that this business is related to the introduction, it is plausible to hypothesise that the introduced cave salamanders have persisted at the site for decades, maybe even for more than a century, given that the quarry populated by these salamanders exists since at least 1896 based on historical maps. The population appears to be highly localised and not invasive, and at present does not appear to represent any danger for native animals or plants. Eradication therefore does not appear to be necessary, and we emphasise that according to German law also introduced populations of wild animals benefit from protection, unless lifted as for instance in the management of invasive species.
