Molecular data reveal the hybrid nature of an introduced population of banded newts (Ommatotriton) in Spain
(2018) In Conservation Genetics 19. p.249-254- Abstract
The three species of banded newt (genus Ommatotriton) are endemic to the Near East. Recently an introduced banded newt population was discovered in Catalonia, Spain. To determine the species involved and the geographical source, we genotyped 11 individuals for one mitochondrial and two nuclear genetic markers, and compared the observed haplotypes to a range-wide phylogeography of Ommatotriton. All haplotypes identified in Spain are identical to haplotypes known from the native range. The mitochondrial haplotypes derive from O. ophryticus and were originally recorded in northeast Turkey. The nuclear haplotypes reveal that all individuals are genetically admixed between O. ophryticus and O. nesterovi. While the geographical resolution for... (More)
The three species of banded newt (genus Ommatotriton) are endemic to the Near East. Recently an introduced banded newt population was discovered in Catalonia, Spain. To determine the species involved and the geographical source, we genotyped 11 individuals for one mitochondrial and two nuclear genetic markers, and compared the observed haplotypes to a range-wide phylogeography of Ommatotriton. All haplotypes identified in Spain are identical to haplotypes known from the native range. The mitochondrial haplotypes derive from O. ophryticus and were originally recorded in northeast Turkey. The nuclear haplotypes reveal that all individuals are genetically admixed between O. ophryticus and O. nesterovi. While the geographical resolution for the nuclear markers is low, the source of the O. nesterovi ancestry must be Turkey, as this species is a Turkish endemic. Species distribution models suggest a large potential distribution for the two Ommatotriton species, extending over northern Iberia and southern France. The ecology of hybrids can differ substantially from that of the parent species, making the impact of the Spanish hybrid banded newt population difficult to predict.
