The evolution of clinal variation has become a topic widely studied for invasive species. Most studies of this kind have found significant correlations between latitude and various plant traits, usually using univariate analytic methods. However, plants are composed of multiple, interacting traits, and it is this correlation among traits that can affect how quickly or even whether the populations...
Invasive plants of Lythrum salicaria (purple loosestrife), a species native to Eurasia, exhibit different ecological strategies to indigenous plants by growing more vigorously. The hypothesis is tested that the more vigorous growth of invasive L. salicaria plants is a result of differences in dry weight partitioning between native and non-native plants. Plants of three native Central European and...
