“…Literature data suggest that global warming might induce the dominance of invasive species over natives (Netten et al, 2010), but our results are consistent with this statement only for L. hexapetala, and mostly when the warming occurs in spring.…”

The rise of global surface temperature by between 1.2°C and 4°C by 2100 is expected to affect freshwater ecosystems and the growth of aquatic plants. By extending the distribution range of invasive macrophytes, climate warming could increase their management costs. The aim of this study was to test the impact of a 3°C warming in spring and in summer on the morphology and physiology Page 2/34 of two native species (Mentha aquatica, Myosotis scorpioides) and two invasive species (Ludwigia hexapetala, Myriophyllum aquaticum) under controlled conditions. Our study showed that the increase of spring temperature induced morphological modifications for all species, while a 3°C warming induced changes in carbohydrates composition for native species in spring, and modification of carbohydrate content for invasive species at both seasons. Patterns of carbohydrate content group the two invasive species together, possibly highlighting common physiological mechanisms. Moreover, the increase of spring temperature favoured the apical and/or lateral growth solely for invasive species. Hence, the invasive species specific response to warming suggests that higher temperature may favour their growth in spring, which might allow them to colonise the water column earlier than natives. This competitive advantage could affect aquatic ecosystems functioning and biodiversity in the coming years.

“…As the nutrient uptake efficiency is important, much work has been done on the floating plant chosen for the treatment of polluted waters [20,21], improvement of the purification capability of FTWs [7,13,17], and analysis of factors influencing the performance of the FTWs [8,10,[22][23][24]. Among studies on FTWs, the purification effect of FTWs on eutrophicated water has been reported from several works [11,13,16,17,25].…”

“…In nutrient-limited environments, the model predicts that with increasing nutrient levels, submerged plants are outcompeted by floating plants. This pattern was also found in field studies and mesocosm studies (Portielje and Roijackers 1995;Janes et al 1996;Forchhammer 1999;Netten et al 2010). At intermediate nutrient levels, floating and submerged plants can either coexist or are alternative stable states, depending on their resource consumption.…”

“…Therefore, the occurrence of free-floating plants can be understood by studying their competition with submerged plants for light and nutrients. Although there have been empirical studies on the competition between floating and submerged plants using laboratory experiments (Janes et al 1996;Szabo et al 2010), mesocosm experiments (Feuchtmayr et al 2009;Netten et al 2010;Lu et al 2013;Smith 2014), and field experiments (Portielje and Roijackers 1995;Forchhammer 1999), the theoretical understanding of the competition between floating and submerged plants for light and nutrients is still limited.…”

Online enhancement: appendixes.abstract: Dominance of free-floating plants poses a threat to biodiversity in many freshwater ecosystems. Here we propose a theoretical framework to understand this dominance, by modeling the competition for light and nutrients in a layered community of floating and submerged plants. The model shows that at high supply of light and nutrients, floating plants always dominate due to their primacy for light, even when submerged plants have lower minimal resource requirements. The model also shows that floating-plant dominance cannot be an alternative stable state in light-limited environments but only in nutrient-limited environments, depending on the plants' resource consumption traits. Compared to unlayered communities, the asymmetry in competition for light-coincident with symmetry in competition for nutrients-leads to fundamentally different results: competition outcomes can no longer be predicted from species traits such as minimal resource requirements (R * rule) and resource consumption. Also, the same two species can, depending on the environment, coexist or be alternative stable states. When applied to two common plant species in temperate regions, both the model and field data suggest that floating-plant dominance is unlikely to be an alternative stable state.
