Megjegyzések:	Trait-based approaches are widely used in community ecology and invasion biology to unravel underlying mechanisms of vegetaton dynamics. Although fundamental tradeoffs between specifc traits and invasibility are well described among terrestrial plants, litle is known about their role and functon in aquatc plant species. In this study, we examine the functonal differences of aquatc alien and natve plants statng that alien and natve species differ in selected leaf traits. Our investgaton is based on 60 taxa (21 alien and 39 natve) collected from 22 freshwater units of Hungarian and Italian lowlands and highlands. Linear mixed models were used to investgate the effects of natveness on four fundamental traits (leaf area, leaf dry mater content, specifc leaf area, and leaf nitrogen content), while the influence of growth-form, alttude, and site were employed simultaneously. We found signifcantly higher values of leaf areas and signifcantly lower values of specifc leaf areas for alien species if growth-form was included in the model as an additonal predictor.We showed that the trait-based approach of autochthony can apply to aquatc environments similar to terrestrial ones, and leaf traits have relevance in explaining aquatc plant ecology whether traits are combined with growth-forms as a fxed factor. Our results confrm the importance of traits related to compettve ability in the process of aquatc plant invasions. Alien aquatc plants can be characterized as species producing sof leaves faster. We argue that the functonal traits of alien aquatc plants are strongly growth-form dependent. Using the trait-based approach, we found reliable characteristcs of aquatc plants related to species invasions, which might be used, for example, in conservaton management.
