Megjegyzések:	Sporobolus cryptandrus, a North American C4 grass, has recently invaded European sandy grasslands, particularly in Central Europe (Hungary), where it threatens native plant communities. As allelopathy has been documented for other Sporobolus species, we tested whether litter from S. cryptandrus has a different effect on the germination and seedling emergence of native grassland species compared to native grass litter. We examined nine native grassland species and S. cryptandrus under three treatments: no litter (control), native litter and S. cryptandrus litter. We hypothesized the followings: (i) Litter addition can hinder germination compared to no-litter control because litter imposes physicochemical barriers. (ii) Following the Novel Weapons Hypothesis, Sporobolus litter may exert a stronger negative effect on native species than native grass litter. (iii) Litter effects are likely species-specific due to interspecific differences in traits and sensitivity to microenvironmental changes. Litter presence did not have a consistent negative effect across species, Sporobolus litter negatively affected germination only in Bromus tectorum. For most other species, the effects of native and Sporobolus litter were highly similar, suggesting that Sporobolus litter did not introduce physicochemical characteristics sufficiently different from native litter to produce distinct effects on native species. However, the suppression of B. tectorum germination by Sporobolus litter may indicate potential allelopathic effects. These findings suggest species-specific litter effects and highlight that Sporobolus litter could offer novel insights for managing B. tectorum, a problem- atic invader in North America. Future research should explore the long-term effects of Sporobolus litter in guiding restoration actions and invasive species management.

Cím:	Does disturbance enhance the competitive effect of the invasive Solidago canadensis on the performance of two native grasses? / Annamária Fenesi, Júliánna Geréd, Scott J. Meiners, Béla Tóthmérész, Péter Török, Eszter Ruprecht

Megjegyzések:	The impact of invasive species on native plant communities can strongly depend on habitat disturbances. Thus, the joint study of invasion and disturbances are necessary to distinguish whether invasive species (1) are just 'passengers' of major environmental changes, (2) are the real cause (drivers) of native species decline, or (3) do disturbances and invasive species additively suppress native species (back-seat drivers). Therefore, we experimentally explored both the single and additive effect of competition by an invasive species and fire as disturbance on the performance of native species. We examined the responses of two native rhizomatous perennial grass species (Elymus repens and Brachypodium pinnatum) to competition with European invasive and American native Solidago canadensis. This was done under burned and unburned conditions, a novel disturbance type in this system. We found that competition with S. canadensis had a very strong negative effect on the performance of B. pinnatum irrespective of disturbance. In contrast, disturbance and competition had a cumulative negative influence on the performance of E. repens, with competition having greater effect than burning. Fire reduced the number of shoots of European S. canadensis individuals, but did not affect the frequently burned American populations. However, these differences did not translate into increased competitive ability of European populations compared with American ones. Thus, the competitive superiority of S. canadensis irrespective of continent of origin explained the performance loss in B. pinnatum (♭driver' model); whereas reduced performance after burning of grass species and competitive superiority of the invasive species jointly decreased the performance of E. repens (♭back-seat driver' model).
