1. Increased ammonium concentrations and decreased light availability in a water column have been reported to adversely affect submersed vegetation eutrophic waters worldwide. 2. We studied the chronic effects of moderate enrichment (NH4–N: 0.16–0.25 mg L−1) on growth carbon nitrogen metabolism three macrophytes (Ceratophyllum demersum, Myriophyllum spicatum Vallisneria natans) under contrasting 2-month experiment. 3. The greatly increased contents free amino acids shoot / leaf macrophytes....
Abstract Functional trait composition of plant communities has been proposed as a helpful key for understanding the mechanisms biodiversity effects on ecosystem functioning. In this study, we applied step‐wise modeling procedure to test relative taxonomic diversity, functional identity, and diversity macrophytes community productivity along water depth gradient. We sampled 42 plots 1513 individual plants measured 16 traits abundance 17 macrophyte species. Results showed that there was...
Experimental and field studies were conducted to evaluate the effects of NH4+ enrichment on growth distribution submersed macrophyte, Vallisneria natans L, in lakes Yangtze River China, based balance between free amino acids (FAA) soluble carbohydrates (SC) plant tissue. Increase rather than NO3– concentrations water column caused FAA accumulation SC depletion plant. The showed a unimodal pattern biomass along both FAA/SC ratios external concentrations, indicating that moderate NH4-N...
To evaluate the relative importance of photosynthetic versus morphological adaptations submersed macrophytes to low light intensity in lakes, rapid curves (RLCs), parameters, growth rate (RGR), clonal reproduction and abundance two (Potamogeton maackianus Vallisneria natans) were examined under 2.8%, 7.1%, 17.1% 39.5% ambient a field outdoor experimental study. The plants increased their initial slope RLCs (α) decreased minimum saturating irradiance (Ek) maximum electron transport (ETRm)...
Summary Trait‐based approaches provide a framework for integrating the distribution of functional traits associated with ecological strategies into responses plant community dynamics along environmental gradients. We used trait‐based approach to unravel processes governing macrophyte assembly water depth gradient. sampled 42 plots and 1513 individual plants measured 12 abundance 17 species. The results showed significant evidences habitat filtering (i.e. reduction in range variance trait...
ABSTRACT Acute biochemical responses of Potamogeton crispus L. to high external ammonium were investigated in an aquarium experiment. Shoots P: incubated aquaria for 24 h or 48 at five treatments ammonium-0, 1, 5, 10 and 20 mg/L NH4-N. Soluble sugar content the shoots declined markedly with increasing levels, whereas soluble amino acid increased dramatically. Responses two antioxidant enzymes as well protein fit a lognormal distribution levels. High levels (NH4-N≥5 mg/L) caused significant...
Light is a major limiting resource in aquatic ecosystems and numerous studies have investigated the response of submerged macrophytes to low light conditions. However, few tested whether different strategies can also consequences for macrophyte distribution along littoral slopes lakes, which are known affect biomass due differences drag forces sediment characteristic. In this study, we (1) two species growth forms (canopy-forming: Potamogeton maackianus, rosette-type: Vallisneria natans)...
Strategies of carbon (C) and nitrogen (N) utilisation are among the factors determining plant distribution. It has been argued that submersed macrophytes adapted to lower light environments more efficient in maintaining C metabolic homeostasis due their conservative strategy ability balance shortage. We studied how depth distributions 12 Lake Erhai, China, were linked C-N strategies when facing acute [Formula: see text] dosing.[Formula: dosing changed metabolism significantly by decreasing...

Although functional trait variability is increasingly used in community ecology, the scale- and size-dependent aspects of variation are usually disregarded. Here we quantified spatial structure shoot height, branch length, root/shoot ratio leaf number a macrophyte species Potamogeton maackianus, then disentangled environmental ontogenetic effects on these traits. Using hierarchical nested design, measured four traits from 681 individuals across five ecological scales: lake, transect, depth...
