Common Ragweed (IMAGE)
Caption
Common ragweed is an annual plant whose allergenic pollen affects human health. It's an invasive species particularly well-adapted to living at roadsides. New research, published in in the open-access, peer-reviewed journal NeoBiota, found high population growth along high-traffic roads even in shaded and less disturbed road sections, suggesting that seed dispersal by vehicles and by road maintenance can compensate, at least partly, for less favorable habitat conditions.
