Provenance of Ichthyosaura alpestris (Caudata: Salamandridae) introductions to France and New Zealand assessed by mitochondrial DNA analysis

Year: 2016

Type: article

Abstract: The last century has seen an unparalleled movement of species around the planet as a direct result of human activity, which has been a major contributor to the biodiversity crisis.Amphibians represent a particularly vulnerable group, exacerbated by the devastating effects of chytrid fungi.We report the malicious translocation and establishment of the alpine newt (Ichthyosaura alpestris) to its virtual antipode in North Island of New Zealand.We use network analysis of mitochondrial DNA haplotypes to identify the original source population as I. a. apuana from Tuscany, Italy.Additionally, a population in southern France, presumed to be introduced, is identified as I. a. alpestris from western Europe.However, the presence of two differentiated haplotypes suggests a mixed origin.This type of analysis is made possible by the recent availability of a phylogenetic analysis of the species throughout its natural range.We discuss the particulars of both introductions.
