4 paź 2021 · Hogweed invasion increased nematode abundance, number of bacterivores and plant parasites, and decreased abundance of omnivores, while total nematode biomass and species diversity were not affected by invasion.
28 sie 2018 · Hogweed is an extremely successful invader in part due to its prolific seed production and growth rate. These attributes coupled with its large size allow giant hogweed to significantly alter natural environments and plant community structures.
15 cze 2022 · We used MaxEnt to predict range expansion and contraction of invasive giant hogweed. Coldest quarter temperature was the most important constraint on its distribution. Most of its current distribution will be lost under climate change in all scenarios.
4 paź 2021 · This study assessed the effect of giant hogweed invasion on the communities of plants and soil nematodes in the riparian habitat. We found that invasion by H. mantegazzianum increased soil pH, decreased carbon and nitrogen content, reduced the number and coverage of the native plant species, and influenced nematode communities and their structures.
16 sie 2013 · In this study, we explored the impact of an invasive plant Heracleum mantegazzianum (giant hogweed) at 24 grassland sites invaded for different periods of time (from 11 to 48 years). Native species' richness and productivity were initially reduced by hogweed invasion but tended to recover after ~30 years of hogweed residence at the sites.
3 lis 2021 · Giant hogweed is a globally invasive plant that can cause a phototoxic reaction which can cause burns and hyperpigmentation. As a result, the species can have large economic costs and human health impacts where high plant densities and high human densities overlap.
29 cze 2022 · Giant hogweed looks like an enormous cow parsley plant. When it's fully grown, it can reach towering heights of between 1.5m to 5m and have a spread of between 1 and 2m. It forms a rosette of jagged, lobed leaves in the first year before sending up a flower spike in the second year and then setting seed.
