| revealing historic invasion patterns and potential invasion sites for two non-native plant species. | the historical spatio-temporal distribution of invasive species is rarely documented, hampering efforts to understand invasion dynamics, especially at regional scales. reconstructing historical invasions through use of herbarium records combined with spatial trend analysis and modeling can elucidate spreading patterns and identify susceptible habitats before invasion occurs. two perennial species were chosen to contrast historic and potential phytogeographies: japanese knotweed (polygonum cuspid ... | 2008 | 18286192 |
