Sesquiterpenoids from Common Ragweed (Ambrosia artemisiifolia L.), an invasive biological polluter

open access: yesPlanta Medica, 2012
AbstractAllergy to common ragweed (Ambrosia artemisiifolia L.) is increasingly important from a clinical standpoint, but surprisingly, little is known on the secondary metabolites of this plant and their potential involvement in the severity of the allergic reactions induced by its pollen.

Using herbarium collections to study genetic responses to global change

open access: yesNew Phytologist, EarlyView.
Summary Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have made the extraction of genetic data from these preserved specimens increasingly feasible, enabling new insights into plant biodiversity and ...

Effect of elevated atmospheric carbon dioxide on the allelopathic potential of common ragweed

open access: yesJournal of Ecology and Environment, 2019
BackgroundAllelopathy has been suggested as one potential mechanism facilitating the successful colonisation and expansion of invasive plants. The impacts of the ongoing elevation in atmospheric carbon dioxide (CO2) on the production of allelochemicals ...

Invasive plants optimize leaf nitrogen allocation in photosynthesis

open access: yesNew Phytologist, EarlyView.
Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.
