The success of invasive species depends on the characteristics of exotic species (their biological traits) and the characteristics of their introduced habitats (biotic and abiotic characteristics). The success of these species will depend on their response strategies to environmental constraints. In this thesis, we focus on the the Large Water Primrose plant species, Ludwigia grandiflora subsp. Hexapetala,. This amphiphyte species is considered as the most invasive aquatic plant in France. The present thesis aims to improve our knowledge on the adaptive strategies of Ludwigia grandiflora to environmental constraints in order to better understand and explain its invasive success. The responses of this species to abiotic parameters and biotic interaction were investigated using a functional traits approach. To achieve these goals, we conducted microcosm and mesocosm experiments. We demonstrated that L. Grandiflora possesses a large adaptive capacity to respond to fluctuations of abiotic factors (e. G. Variation of water depth, light intensity, salinization of ecosystems). Furthermore, our results showed that L. Grandiflora had a high growth rate, compensated herbivore damages and was able to produce a dense canopy in response to competition. However, the response strategy of L. Grandiflora to biotic pressure (competition and predation) depended on its own density, on the density and the status (native vs exotic) of neighboring species and on its environment (terrestrial vs aquatic). The response strategies of L. Grandiflora face to abiotic parameters and biotic pressure could explain its invasive success

Submerged macrophytes stabilize the clear-water status in shallow lakes, supporting many ecosystem services. Shallow lakes are exposed to agricultural runoff (ARO) containing pesticides and nutrients, which can affect macrophytes and threaten the clear-water state. Recent studies show that nitrate may affect macrophyte growth and species richness. Pesticides can also affect macrophytes directly or indirectly by disrupting biotic interactions. Climate warming is an additional stress to shallow lakes. lncreased temperatures may promote phytoplankton growth and nutrient release or can modify top-down control. The combined stressors may have additive, synergistic or reversed effects, and these effects are difficult to predict. The objectives of this thesis were to investigate (1) the individual and combined effects of nitrate, pesticides and climate warming on macrophytes (2) whether upscaling from micro- to mesocosms would preserve the response of macrophytes; and (3) whether the stressor effects could be detected in the macrophyte physiology. Several experiments integrating different functional groups (macrophytes, phytoplankton, periphyton and their respective consumers) were performed under controlled conditions (laboratory microcosms). These ecosystem models were exposed for several weeks to a simplified cocktail simulating an ARO (nitrates alone or mixed with 4 pesticides) at two temperatures (ambient and +4°C). Following this, more realistic ecosystems were studied using outdoor mesocosms exposed to ARO and simulating the same type of heating (semi-controlled conditions). ln all these experiments, the response of the macrophytes was documented by measuring their growth (biomass, size) and physiology (photosynthetic pigments, phenolic compounds, anthocyanins, elemental stoichiometry). Results from the microcosms showed that all functional groups were affected directly or indirectly by the tested stress factors. Pesticides alone but not nitrate reduced macrophyte biomass. Nitrate and pesticides in combination acted synergistically reducing the resilience of the macrophyte-dominated state. Warming marginally promoted macrophyte growth but together with ARO reduced macrophyte growth (objective 1). Results from the mesocosms showed that the strong negative effect of ARO on the growth of macrophytes was preserved in the outdoor mesocosms but only at ambient temperature. Warming enhanced macrophyte growth, similar to the microcosms, but also significantly buffered the ARO effect, highlighting different responses compared with the microcosms (objective 2). Complex biotic interactions along with invasions of invertebrate larvae may have reversed responses to the stressors. Besides their effects on growth, ARO and warming had a significant effect on the content of carotenoids, phenolic compounds and stoichiometry. These results need to be confirmed to determine their relevance as early warning signals of stress (objective 3). This thesis shows that the exposure of shallow lakes to ARO can induce regime shifts by tipping the system towards a degraded state dominated by phytoplankton. ln particular, the role of nitrate, which is much less studied compared to phosphorus, is clearly highlighted. Despite the positive effects of warming on macrophyte growth, the three stressors combined (pesticides, nitrates and warming) reversed the expected effect and led to a sharp decline in macrophyte biomass. The change in scale achieved confirms the need to better take into account the complexity of biotic interactions for a more reliable assessment of the environmental risks to which aquatic ecosystems are exposed

Climatic models predict a rise of globale surface temperature about 1 to 4°C by 2100. Climate modifications generated by this warming might favor biological invasions. The general objectif of this thesis was to explore the impacts of climate warming and climate change on four macrophytes invasive in Europe. This work focused on germination, growth, physiology and distribution of these species, through experiments in controlled conditions, in experimental garden and by using species distribution models. We showed that i) higher temperatures favor moderately the germination capacity of Ludwigia hexapetala and Ludwigia peploides subsp. montevidensis, decrease the seedlings survivorship but improve their biomass production, ii) the effect of increased temperature on macrophytes depends on the season, iii) a 3°C warming can modify metabolism without generating changes on the growth, iv) the water primroses L. hexapetala is the only species that showed both better apical and lateral growth when facing a warming, v) models predict an increase of the distribution surface of Ludwigia spp., Myriophyllum aquaticum and E. densa in their invasive ranges, and a decrease of their distribution area in the other continents, including their native range. This thesis offer a better understanding of climate changes consequences on invasive macrophytes in order to anticipate their futur colonisation potential

Adaptive phenotypic plasticity results in an improvement of plant performance and hence an increase of fitness. This study focused on plastic responses of two higher aquatic species exposed to hydraulic stress (current). This study revealed two contrasting ategies: high resistance to breaking and uprooting for the first one vs. Escape from stress (size reduction) for the other one, without decrease of fitness. The latter species displayed an altered clonal growth pattern in response to hydraulic stress (e. G. More compact growth form, high clonal growth to the detriment of vertical expansion of the main individual). The stress release leads to compensatory growth at both individual and clone scale. The morphological response to hydraulic stress is regulated by the nutrient level (growth favored for intermediate velocity and high nutrient levels)

Aquatic macrophytes are a functional group of hydrosystems with numerous ecological rules. Large rivers are ecosystems often impacted by human activity and present strong physical constraints. However, large rivers have been little studied. The principal aim of this study is to analyse the determinism of the macrophytes communities with a multi-scale approach (different space and time scales) in eight sites on the rivers Dordogne and Garonne. Ranunculus fluitans communities are similar in the two rivers and are characteristic of meso-eutrophic and running waters. Physical parameters (depth, substratum, water velocity) represent the principal factors affecting the floristic composition and the abundance of the macrophytes at the station scale as well as at the local scale. Compared with small rivers, chemical parameters only have little influence. The hydrological factors are especially structuring at the different temporal scales. Floods are the major source of disturbances and their impacts are often observed during several years. We showed the complex interactions between plants and flow. The macrophytes especially modify the water heights and velocities. Using a biological growth model (Gompertz model) associated with the hydrological constraints we proposed the bases of a dynamic model of growth for the aquatic macrophyte communities in large river. This thesis allowed us to improve knowledge on the functioning of plant communities in large rivers and to evaluate the implication of these results for surveying and sampling macrophytes in large rivers especially when applying the Macrophyte Biological Index for Rivers
