Many invasive species of North America originate in Eurasia, and vice versa.
Purple loosestrife, Lythrum salicaria, for example, grows along streams
and rivers in Turkey, where it is a native species. However, where introduced
in North America, it has come to dominate the species composition, particularly
in northern wetlands. In native habitats in Turkey, Lythrum salicaria does not dominate the wetlands in this way. Study of the factors that constrain
species in their native environments can be of benefit in controlling these
species in places where they have been introduced. Below is a link to a list
of species that have been introduced to North America and that occur in Turkey.
Study of species in their native habitats would be of value in their control
