Plants that have grown in partnership with human activity in meadows can be a great source of seeds for restoration projects, but their ability to germinate is also a problem.
Do variations in dormancy and germination across achenes from peripheral, intermediate and central positions contribute to the success of the cold desert annual Heteracia szovitsii?
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.
This paper provides an important case study in the large family Asteraceae that contains almost one-tenth of all flowering plants and has an enormous diversity of leaf forms.
