Abstract

Exotic plants can compete well with native species because many invasive species are considered better nutrient users in both low- and high-resource environments. However, whether invasive plants can outperform native plants at all stages of invasion is not very clear. We investigated the nitrogen (N), phosphorus (P) and N:P homeostasis of an invasive Eupatorium adenophorum and a co-occurring native plant Artemisia argyi in an area across the five invasion stages of E. adenophorum. The N homeostasis (HN) of E. adenophorum was higher than that of A. argyi, whereas the P and N:P homeostasis (HP and HN/P) were higher for A. argyi. For E. adenophorum, HN decreased, but HP and...

Exotic plants can compete well with native species because many invasive species are considered better nutrient users in both low- and high-resource environments. However, whether invasive plants can outperform native plants at all stages of invasion is not very clear. We investigated the nitrogen (N), phosphorus (P) and N:P homeostasis of an invasive Eupatorium adenophorum and a co-occurring native plant Artemisia argyi in an area across the five invasion stages of E. adenophorum. The N homeostasis (HN) of E. adenophorum was higher than that of A. argyi, whereas the P and N:P homeostasis (HP and HN/P) were higher for A. argyi. For E. adenophorum, HN decreased, but HP and HN /P increased with the invasion time. For A. argyi, HN /P increased, HP and HN remained stable with the invasion time. The results demonstrated that E. adenophorum could maintain higher HN during invasion stages when N was limited and could maintain higher HN and HP at invasion stages when P was more limited. This rapid nitrogen and phosphorus homeostasis transformation of invasive E. adenophorum during its invasion stages guarantees its stronger competitive ability over native species and promotes its invasion success.
