Distribution of Ragweed

Common ragweed (Ambrosia artemisiifolia L.) is an invasive species that causes allergies in 10-20 per cent of humans and thus presents a significant public health challenge.

Common ragweed (Ambrosia artemisiifolia L.) is an invasive species that causes allergies in 10-20 per cent of humans and thus presents a significant public health challenge. This study’s physiological model performs well, with the plant’s potential distribution corresponding with GBIF-mediated occurrences in both the native North American range and the invasive range in Europe. However, the model also predicts a much larger potential range for ragweed than currently observed, in part due to improved estimates on the amount and timing of pollen release.
