“…However, not all freshwater species behave in the same way, and most of them -even those belonging to the same family -have completely different vegetative periods and reproductive methods that are often associated with their adaptation to seasonally changeable abiotic factors [13]. Many of these factors, including temperature or the availability of light and water nutrients, have been extensively studied [e.g., [14][15]. For instance, Riis et al [14] claimed that aquatic macrophytes spread differently in relation to changing conditions (i.e., water temperature or light availability).…”

Two common Potamogeton species, Potamogeton pectinatus L. and Potamogeton crispus L., were collected in 2016 and 2017 from a lowland, sandy bed in the Wilga River in Poland to investigate the ability of the plants to adapt to changing hydrological conditions. Measurements included biomechanical properties as well as the morphological characteristics of their stems. Specifically, experiments included three-point bending and tension tests as well as stem diameter and cross-sectional morphology at various periods in the plants' life cycles. Detailed information about the seasonal changes in biomechanical traits and the similarities between the two investigated plants are presented. The data show significant differences in the three-point bending and tension parameters. The flexural rigidity proved to be the most sensitive parameter to changes in hydrological conditions during the season. The maximum forces in the three-point bending tests needed to complete the fracture of P. crispus were much higher, reaching values up to 0.097 N, than those for P. pectinatus (0.035 N), due to P. crispus having thicker shoots, which resulted in greater resistance to elastic deformity. Moreover, the modulus of elasticity values shows that P. pectinatus is much more prone to return to its original shape after the removal of the acting forces. For instance, the maximum Young's modulus for P. pectinatus was 116.23 MPa, whereas for P. crispus, the highest value was four times lower (26.60 MPa). The present study supplements an aquatic plant biomechanics database that has been created in recent years.

“…High-temperature-induced changes in morphology and biomass allocation may lead to increased growth and competitive capacity (Pilon & Santamaría 2002;Riis et al 2012). For the structure and proper functioning of freshwater ecosystems, competition can be considered a paramount factor determining the species distribution in aquatic macrophyte communities (Moss et al 2003, Doyle et al 2007.…”

There is an information gap regarding heat stress-induced oxidative damage and the species-specific behavior of plants under stress conditions. The present study was designed with the hypothesis that heat stress may induce species-specific oxidative damage that determines the competitive capacity of common submerged macrophytes. We conducted two laboratory experiments to simulate mono-and mixed cultures of three submerged macrophytes with the application of two heat shock treatments. The results showed that both heat shocks had significant effects on growth, photosynthetic pigments and the ability to induce strong oxidative damage for all three species. The comparative results of mono-and mixed cultures showed that P. crispus had an advantage in both the control and hightemperature treatments over the other two species as a strong competitor in the mixed culture. Further, the competitive capacity of P. crispus increased in the moderately high-temperature condition compared to the control. ARTICLE HISTORY

“…Previous studies have also shown that environmental niche shift is related to human influence (Riis et al, 2012;Hussner, 2012;Donoghue and Edwards, 2014;Svirčev et al, 2014;Nunes et al, 2015). API seedlings have been imported to non-native regions for ecological restoration, agricultural production, or even as ornamental plants (De Groot et al, 2002;Leppäkoski et al, 2013;Riis et al, 2012;Kaufman and Kaufman, 2013). Additionally, a period of repeated human colonization in relation to plasticity, establishment, and genetic evolution can result in a successful niche shift.…”

-Environmental niche conservatism defines a concept, stating that species could live in the same environmental condition in both native and invasive ranges. Niche modeling often used this as basis for the prediction of the range of invasive plants. However, it is debatable whether environmental niches of invasive plant species are conserved or shift between native and invasive ranges. Only few studies have investigated such a shift in aquatic plant invaders (APIs) on a meaningful global scale. Environmental niche modeling was used to project climatic niche distributions of 10 APIs based both on the native range and the invasive range of species. We found that niche shifts of APIs between native and invasive ranges may occur throughout the world. Moreover, we found niche shifts of APIs between native and invasive ranges across different biomes. The largest climatic niche shift was detected for Najas minor and the smallest for Alternanthera philoxeroides. For all 10 APIs, overlap between both ranges was maximal for large river deltas, while overlap was minimal for temperate floodplain rivers and wetlands. For APIs, the suitability of the climatic habitat was highest in temperate coastal rivers for invasive models in invasive ranges. More importantly, based on invasive models, climatic suitability was significantly higher for temperate coastal rivers and temperate floodplain rivers and wetlands in invasive ranges and compared to native models. We suggest to integrate climatic niches of both native and invasive ranges into projections of the global climatic niche distribution of APIs.Keywords: climatic niche shift / aquatic plant species / biomes / niche overlap / plant invasion Résumé -Changement de niche climatique de plantes aquatiques invasives des habitats natifs aux habitats envahis : un test utilisant 10 espèces de différents biomes à une échelle globale. Le conservatisme de niche environnementale définit un concept, affirmant que les espèces pourraient vivre dans les mêmes conditions environnementales dans les habitats indigènes et invasifs. La modélisation de niche a souvent servi de base à la prédiction de l'extension des plantes envahissantes. Cependant, cela est discutable si les niches environnementales des espèces de plantes envahissantes sont conservées ou se modifient entre les aires indigènes et invasives. Seules quelques études ont étudié un tel changement chez les plantes aquatiques invasives (API) à une échelle mondiale significative. La modélisation de niche environnementale a été utilisée pour projeter des distributions de niches climatiques de 10 API basées à la fois sur la répartition native et invasive d'espèces. Nous avons constaté que des changements de niche des API entre les aires indigènes et invasives peuvent se produire dans le monde entier. En outre, nous avons trouvé des changements de niche des API entre les aires indigènes et invasives entre différents biomes. Le plus grand changement de niche climatique a été détecté chez Najas minor et le plus petit pour Alternanthera p...
