Resprouting potential of rhizome fragments in an invasive aquatic plant
Non-native aquatic Ludwigia species from a polyploid complex are among the world’s most problematic invasive plants. A new paper in AoBP finds out why.
Loss of functional diversity and network modularity in introduced plant–fungal symbioses
Native and alien trees associate with a wide range of beneficial fungi, but the few studies of these interactions tend to focus only on a few plant species or locations at a time. This approach limits broad scale...
From South America to Shenzhen, China; road trip of an invasive weed
The South American weed Mikania micrantha has spread rapidly across Southern China since its introduction to the Shenzhen region in 1984. Geng et al. used SSR markers to investigate and map genetic diversification of...

Trait responses of invasive aquatic macrophyte congeners: colonizing diploid outperforms polyploidy
Polyploidy (multiple copies of whole genomes) is over-represented in invasive plants and thought to promote their success in novel environments. Understanding functional traits supporting colonization can provide a...

Demographic consequences of genetic variation for a plant invasion
Genetic variation may play an important role in plant population fitness and invasion success. Li et al. combine genetic analysis and demographic data to investigate the consequences of genetic variation for the...
Genetic analysis of spatial overlap by invasive vines
Kartzinel et al. use genetic markers to determine the extent and overlap of genetically unique kudzu vines (Pueraria montana var. lobata) in multiple patches over 2 years, and find that, contrary to expectations...
Polyploidy and plant invasions (Invited Review)
Biological invasions are a major ecological and socio-economic problem in many parts of the world. Te Beest et al. synthesize current knowledge on the importance of polyploidy for the invasion of introduced plants, and...
