Positive responses of coastal dune plants to soil conditioning by the invasive Lupinus nootkatensis

摘要: Abstract Invasive nitrogen-fixing plants drive vegetation dynamics and may cause irreversible changes in nutrient-limited ecosystems through increased soil resources. We studied how conditioning by the invasive alien Lupinus nootkatensis affected seedling growth of co-occurring native plant species coastal dunes, whether responses to lupin-conditioned could be explained fertilisation effects interacting with specific ecological strategies dune species. Seedling performance was compared a greenhouse experiment using field-collected from within or outside lupin stands. In associated experiments, we quantified response nutrient supply each tested addition nutrients grass Festuca arundinacea control soil. found that biomass 30 out 32 species; conditioned also had positive effect on itself. Increased phosphorus mobilisation lupins major factor driving these responses, based both elements analyses available nutrients. There were large differences among species, but they unrelated selected autecological indicators strategies. conclude removes limitation for it increases cycling other nutrients, promoting its own seedlings wide range Finally, our study indicates there are no negative legacies prevent re-establishment after removal lupins.
