Complex and Dynamic Effects of an Extreme Low Temperature Weather Event on Invasive Plant Populations and Resident Communities [PDF]
Global Change Biology, Volume 31, Issue 3, March 2025.Invasive plant species might benefit more from climate change, though evidence for that is not clear. Here, we show that the effects of a low‐temperature extreme weather event can result in a dramatic reduction in both vegetative and reproductive growth of invasive populations of Gunnera tinctoria (giant rhubarb) in the west of Ireland.
