The extent to which propagule pressure limits the establishment of local polyploid populations remains to be determined, because we know so little.
The highest increases in spread rates occur when variation in dispersal positively co-varies with fecundity.
Finding the factors that explain invasion success of species is a major objective in ecology. The combination of extensive data on fruit heteromorphism in Asteraceae and the largest global plant-naturalization database offered the unprecedented possibility to add a missing piece to the naturalization-success puzzle.
For conservation of rare riparian species, avoiding an impact to hydrodynamic processes, such as water tables and flooding dynamics, may be just as critical as avoiding direct impacts on the number of plants.
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, patches are not dominated by one or a few genets.
