“…Most specimens of X. laevis were exported through a single organization and represent a genetic lineage originating from the southwestern Cape region of South Africa (De Busschere et al, 2016;Lillo, Dufresnes, Faraone, Lo Valvo, & Stock, 2013;Lobos, Mendez, Cattan, & Jaksic, 2014;van Sittert & Measey, 2016). However, other lineages were detected in France suggesting that this invasive population is composed of animals from multiple source populations (De Busschere et al, 2016). Although X. laevis predominantly colonizes areas with equivalent climatic conditions, populations have also been established in temperate regions characterized by an oceanic climate (Fouquet & Measey, 2006;Measey & Tinsley, 1998;Rubel & Kottek, 2010).…”
