“…Our results verified the general bivariate relationships between N mass , P mass , and SLA, which have been well documented both on global (Güsewell and Koerselman, 2002;Reich et al, 2010;Pan et al, 2020a) and regional (He et al, 2006;Xia et al, 2014;Dalke et al, 2018) scales. Thomas et al (2020) extended the plant trait relationships to tundra biome, and found that tundra plants demonstrated similar resource economic traits in extremely harsh environments, just like that in the alpine climate in this study.…”

“…SLA of sedges are higher than that of grasses, and increase with increasing GSP. Light regime is another environmental factor in affecting plant leaf construction (Long et al, 2011;Dalke et al, 2018). An in situ field experiment showed that enhanced radiation induced thicker leaves of two common but not dominant species, Saussurea superba and Gentiana straminea on the Tibetan Plateau (Shi et al, 2004), resulting in lower SLA.…”

Plant traits mirror both evolutionary and environmental filtering process with universal trait-trait relationships across plant groups. However, plants also develop unique traits precisely to different habitats, inducing deviations of the trait coupling relations. In this study, we aimed to compare the differences in leaf traits and examine the generality and shifts of trait-trait relationships between alpine aquatic and terrestrial herbaceous plants on the Tibetan Plateau, to explore the precise adaptive strategies of aquatic and terrestrial plants for its habitats. We measured mass-based and area-based leaf N and P concentrations, N:P ratios and specific leaf area (SLA) of aquatic and terrestrial herbaceous plants. Standardized major axis analysis were applied to build the correlations for every trait pairs of each plant group, and then to compare the differences in the trait-trait correlations among different plant groups. Leaf Nmass and Pmass of two groups of aquatic plants (emergent and submerged plants) were higher, but N:P ratios were lower than those of two groups of terrestrial plants (sedges and grasses). Submerged plants had extremely high SLA, while grasses had the lowest SLA. Nmass positively correlated with Pmass in three out of four plant groups. The two terrestrial plant groups had positive Nmass-SLA relationships but these two traits coupled weakly in aquatic plants. Pmass showed positive relationships to SLA in three out of four plant groups. Significant shifts of trait-trait relationships between aquatic and terrestrial plants were observed. In general, aquatic plants, especially submerged plants, are characterized by higher SLA, greater leaf nutrientmass than terrestrial plants, tend to pursue fast-return investment strategies, and represent the acquisitive end of leaf economics spectrum. The deviations of trait-trait relationships between different plant groups reveal the precise adaptions of submerged plants to the unique aquatic habitats.

“…The fact that all AM mycoheterotrophs so far investigated develop the Paris-morphotype (Imhof et al, 2013) led us to ask whether hyphal coils are required for a fungus-to-plant carbon transmission, and whether indeed plant species with Paris-type mycorrhiza might potentially obtain carbon from their fungal source, having green leaves or not. This could also explain why photosynthetic rates of P. quadrifolia and some other Paris-type AM plants appear to be low compared with Arum-type AM plants (Dalke et al, 2018). To shed light on this question, we applied stable isotope abundance analysis to the two species that once provided the very definition for the AM morphotypes, namely A. maculatum and P. quadrifolia (Gallaud, 1905).…”

“…We quantified plotlevel pubescence as the summed cover of these five species. Data about the mean area of individual leaves were obtained from TRY -a global database of plant traits (53) TRY version 5.0; data used of (54)(55)(56)(57)(58)(59)(60)(61)(62)(63)(64)(65). Three species were not included in the leaf area calculation, since they either had no leaves (Cuscuta europaea and Equisetum pratense) or because there were not data available in the TRY database (Carex praecox).…”

Vegetation characteristics control sediment and nutrient retention on but not underneath vegetation in floodplain meadows

Sediment and nutrient retention are essential ecosystem functions that floodplains provide and that improve river water quality. During floods, the floodplain vegetation retains sediment, which settles on plant surfaces and the soil underneath plants. Both sedimentation processes require that flow velocity is reduced, which may be caused by the topographic features and the vegetation structure of the floodplain. However, the relative importance of these two drivers and their key components have rarely been both quantified. In addition to topographic factors, we expect vegetation height and density, mean leaf size and pubescence, as well as species diversity of the floodplain vegetation to increase the floodplain's capacity for sedimentation. To test this, we measured sediment and nutrients (carbon, nitrogen and phosphorus) both on the vegetation itself and on sediment traps underneath the vegetation after a flood at 24 sites along the River Mulde (Germany). Additionally, we measured biotic and topographic predictor variables. Sedimentation on the vegetation surface was positively driven by plant biomass and the height variation of the vegetation, and decreased with the hydrological distance (total R2=0.56). Sedimentation underneath the vegetation was not driven by any vegetation characteristics but decreased with hydrological distance (total R2=0.42). Carbon, nitrogen and phosphorus content in the sediment on the traps increased with the total amount of sediment (total R2=0.64, 0.62 and 0.84, respectively), while C, N and P on the vegetation additionally increased with hydrological distance (total R2=0.80, 0.79 and 0.92, respectively). This offers the potential to promote sediment and especially nutrient retention via vegetation management, such as adapted mowing. The pronounced signal of the hydrological distance to the river emphasises the importance of a laterally connected floodplain with abandoned meanders and morphological depressions. Our study improves our understanding of the locations where floodplain management has its most significant impact on sediment and nutrient retention to increase water purification processes.
