Gunnera tinctoria is an unusual N-fixing plant species that has become invasive worldwide, generally in environments with a low evaporative demand and/or high rainfall. Amongst the many mechanisms that may explain its success as an introduced species, a contrasting phenology could be important but this may depend on an ability to grow and utilize nutrients under sub-optimal conditions. We examined whether G. tinctoria has an advantage in terms of a contrasting phenology and N-fixing capability, in comparisons with Juncus effusus, the native species most impacted by G. tinctoria invasions.

入侵性古那纳菌的生长，物候和氮利用

Gunnera tinctoria是一种不寻常的固氮植物，通常在蒸发需求低和/或降雨多的环境中，已在全世界范围内入侵。在许多可以解释其作为引进物种成功的机制中，相反的物候可能很重要，但这可能取决于在次优条件下生长和利用养分的能力。我们检查是否G. tinctoria在对比物候和固氮能力，有比较方面具有优势灯心草，原生种最受影响G. tinctoria入侵。
