Abstract
Interspecies transfer of mitochondrial (mt) DNA is a common phenomenon in plants, invertebrates, and vertebrates, normally linked with hybridization of closely related species in zones of sympatry or parapatry. In Central Europe, in an area north of 48° N latitude and between 08° and 22° E longitude, western Palearctic water frogs show massive unidirectional introgression of mtDNA: 33.7% of 407
R. ridibunda
possessed mtDNA specific for
R. lessonae
. In contrast, no
R. lessonae
with
R. ridibunda
mtDNA was observed. That
R. ridibunda
with introgressed mitochondrial genomes were found exclusively within the range of the hybrid
R. esculenta
and that most hybrids had
lessonae
mtDNA (90.4% of 335 individuals investigated) is evidence that
R. esculenta
serves as a vehicle for transfer of
lessonae
mtDNA into
R. ridibunda
. Such introgression has occurred several times independently. The abundance and wide distribution of individuals with introgressed mitochondrial genomes show that
R. lessonae
mt genomes work successfully in a
R. ridibunda
chromosomal background despite their high sequence divergence from
R. ridibunda
mtDNAs (14.2–15.2% in the ND2/ND3 genes). Greater effectiveness of enzymes encoded by
R. lessonae
mtDNA may be advantageous to individuals of
R. ridibunda
and probably
R. esculenta
in the northern parts of their ranges.
