| population genetics of a successful invader: the marsh frog rana ridibunda in britain. | we investigated the genetic outcome of successful invasion by an alien species, the marsh frog rana ridibunda, in britain. twelve adults translocated from hungary into kent (romney) in 1935 resulted rapidly in a large localized population. a further successful translocation in 1973 from romney to sussex (lewes), together with other range extensions, provided an opportunity to test bottleneck effects during colonization events. romney and lewes frogs had similar genetic diversities to those in hu ... | 2003 | 12675820 |
