Dataset of Rapid adaptive responses of rosette-type macrophyte Vallisneria natans juveniles to varying water depths: The role of leaf trait plasticity
<p>Rosette-type submerged macrophytes are widely distributed across a range of water depths in shallow lakes and play a key role in maintaining ecosystem structures and functions. However, little is known about the rapid adaptive responses of such macrophytes to variations in water depth, especially at the juvenile stage. Here, we conducted a short term <i>in situ</i> mesocosm experiment, in which the juveniles of <i>Vallisneria natans</i> were exposed to a water depth gradient ranging from 20 to 360 cm. Twenty-two leaf-related traits were examined after four weeks of growth in a shallow lake. Most (18) traits of <i>V. natans</i> generally showed high plasticity in relation to water depth. Specifically, juveniles allocated more biomass to leaves, and had higher specific leaf area, leaf length to width ratio, chlorophyll content, and carotenoids content in deep waters, displaying trait syndrome associated with high resource acquisition. In contrast, <i>V. natans</i> juveniles in shallow waters had higher leaf dry matter content, leaf soluble carbohydrate content, carotenoids per unit chlorophyll, and peroxidase activity, pertaining to resource conservation. Notably, underwater light intensity was found to be the key factor explaining the trait plasticity along the water depth gradient, and 1.30 mol photons m<sup>–2</sup> d<sup>–1 </sup>(at 270 cm) could be the optimal irradience level based on the total biomass of <i>V. natans</i> juveniles. The present study highlights the significance of leaf trait plasticity for rosette-type macrophytes in response to variations in water depth, and sheds new light on the differences between trade-offs in deep- and shallow-water areas.</p>

LT-Brazil: A database of leaf traits across biomes and vegetation types in Brazil
<p>The LT-Brazil data set contains observations of leaf mass per area, leaf N and P concentration per unit mass, and leaf N:P ratio from native woody species across the Brazilian territory, encompassing information of biome, vegetation, taxonomic data, geographical coordinates, climatic parameters, as well as soil properties. We compiled data from several geographical coordinates in native vegetation distributed across all biomes (i.e., Amazônia, Caatinga, Cerrado, Mata Atlântica, Pampa, and Pantanal) found in Brazil. Our compilation was focused on native woody plants (i.e., trees, shrubs, subshrubs, and lianas), excluding monocots, palm trees, herbs, and hemiparasitic plants. The compiled data set covers <em>c.</em> 9% of woody angiosperm species of Brazil. Unidentified or mixed species were also considered when met our eligibility criteria. Contributions to expand this database can be performed through our repository at GitHub (https://github.com/emariano-git/lt-brazil.git). Major versions of the LT-Brazil data set will also be made available via the TRY Plant Trait Database (https://www.try-db.org).</p>

Data from: Carbon versus nitrogen release from root and leaf litter are modulated by litter position and plant functional type
<p><span>Litters of leaves and roots of different qualities occur naturally above- and belowground, respectively, where they decompose in contrasting </span><span>abiotic and biotic</span><span> environments. Therefore, ecosystem carbon (C) and nitrogen (N) dynamics can be strongly affected by the combination of </span><span>litter </span><span>position and quality. However, it is poorly understood how C versus N turnover of litters depends on the interplay among plant functional type (PFT), organs, traits, and litter position. </span></p> <p><span>In a semi-arid inland dune, soil surface and buried leaf litters and buried fine roots of 25 species across three PFTs (herbs, legume shrubs, and non-legume shrubs) were incubated for 3, 6, 9, 12, 18, and 24 months to investigate litter decomposition and C and N dynamics. Morphological and chemical (nutrient and </span><span>NMR carbon)</span><span> traits of initial litters of leaves and fine roots were determined.</span></p> <p><span>The litter decomposition rates (k values) of surface leaves and buried fine roots did not differ, but buried fine roots and buried leaf litter decomposed faster than surface leaf litter. </span><span>Ratios of <em>k</em> values of surface leaves to buried leaves decreased with the leaf C:N ratio. </span><span>Herbs and legume shrubs decomposed faster than non-legume shrubs for buried fine roots, but not for leaves. </span><span>At given C loss, buried fine roots had higher N loss than leaf litters;</span><span> legume shrubs with relatively higher N or lower C:N ratio had higher N loss than non-legume shrubs.</span><span> Stronger positive relationships between C and N losses were shown in leaves and legume shrubs than in fine roots and non-legume shrubs, respectively.</span></p> <p><span><strong>Synthesis</strong>: The generality of faster N release of legume litters at a given C release highlights the importance of legumes in N cycling in semi-arid ecosystems where N is the limiting factor. The dynamics and coordination of C versus N release as a function of litter quality are modulated by litter position and PFT. These findings have important implications for the development of process-based models on C and N cycles in the context of ongoing global change potentially altering the functional composition of plant communities and the relative quantities and qualities of aboveground versus belowground litter.</span></p>
