Bemerkungen zu den Mauereidechsen Podarcis muralis s.l. (Laurenti, 1768) im Nordwesten von Stuttgart Ausbreitungstendenzen und Hybridisierungen, ihre Auswirkung auf Bestände der Zauneidechse Lacerta agilis Linnaeus, 1758 sowie Überlegungen zum Umgang mit allochthonen Mauereidechsen.

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]
