Urtica kioviensis, a rare species of stinging nettle threatened by hybridization
Original language description
In this study, the interspecific hybridization between the rare species Urtica kioviensis (2x) and its common relative U. dioica (2x, 4x) under natural conditions was identified and quantified. The results indicate that the extent of hybridization varies between sites and is likely to depend on the abundance of the particular species and cytotypes present. Particularly concerning from a conservation point of view is the hybridization between U. kioviensis and the diploid cytotype of U. dioica, which could affect the abundance of U. kioviensis via both genetic and demographic swamping. Based on current knowledge, it is not possible to unequivocally distinguish putative triploid hybrids between U. kioviensis and tetraploid U. dioica, between the diploid and tetraploid cytotypes of U. dioica, or between diploid hybrids (U. dioica 2x × U. kioviensis) and tetraploid U. dioica. Future studies should therefore disentangle the origin of triploids in mixed populations of U. kioviensis and both cytotypes of U. dioica.
