Abstract

The finding of a young adult slow worm, coloured black-blue, from the upper Eisack Valley / Valle Isarco (South Tyrol / Alto Adige [Italy]) is reported. The colouring is attributed to a lack of yellow colour pigments (axanthism). Potential advantages and disadvantages that arise from the colouration are discussed. It is believed that the unusual colouration is due to a spontaneous mutation. At the time of writing this article the specific status of the slow worm occurring in this region is not known. It could be either a specimen of Anguis fragilis Linnaeus, 1758 or one of Anguis veronensis Poll ini, 1818, as well as a hybrid form between these two taxa.

Abstract

The sand lizard (Lacerta agilis Linnaeus, 1758) is one of the most widespread lizards in Europe (Bischoff 1988). Striking in this context is its only local occurrence in Italy (see Lapini et al. 1989, Corti & Lo Cascio 2002, Lapini & Dall'Asta 2004, Sindaco et al. 2009) and the absence of this species in the coastal area of the Mediterranean Sea (e.g. Corti & Lo Cascio 2002, see e.g. Bischoff 1988, distribution map Lacerta agilis on lacerta.de). The literature reveals three provinces along the Alps with reports that are far apart from each other. The question is whether the sand lizard, as assumed by Rahmel (1991), recently occurs in South Tyrol (Alto Adige [Italy]) or occurred historically. This question was investigated on the basis of a literature research, research on museum material, evaluations of databases and field herpetological inspections. The question why the sand lizard was unable to establish itself south of the Alpine arc or only to a limited extent is investigated. The wall lizard Podarcis muralis (Laurenti, 1768) is given importance in this context. [ABSTRACT FROM AUTHOR]

Abstract

We report occurrences of the Common Wall Lizard (Podarcis muralis s.l.) in the previously un-investigated city districts of Feuerbach, Weilimdorf and Botnang in northwestern Stuttgart, Germany. New insights on known occurrences in adjacent city districts, already reported by Deichsel (2011) and Schulte et al. (2008, 2011), are added. With no exception, Stuttgart occurrences of P. m. brongniardii of the Eastern-France lineage, P. m. maculiventris-Wes t of the Southern-Alps lineage, and P. m. nigriventris of the Tuscany lineage, and hybrids of these lineages with each other, are alien. In accordance with Schulte et al. (2021), Blanke & Lorenz (2019), and with Flora-Fauna-Habitat Guidelines of the European Commission (February 2007), we urgently discourage the translocation of alien Wall Lizards in Stuttgart. The expansion potential and assertiveness of these alien animals may be detrimental to ecosystems, and sequelae cannot be corrected. [ABSTRACT FROM AUTHOR]
