Sex-specific strategies of nutrient resorption associated with leaf economics in Populus euphratica
<p><span>There are differences between sexes in physiological and functional traits and possibly in nutrient resorption, particularly in nutrient-poor environments. However, little is known about the extent of nutrient resorption from fine stems and fine roots, and how nutrient resorption is related to leaf economics in the males and females of dioecious trees.</span></p> <p><span>We investigated nutrient resorption of different organs and explored whether nutrient resorption is associated with nutrient conservation traits of leaves (e.g. leaf thickness, leaf mass per area, LMA) in <em>Populus euphratica</em> females and males in four natural forests along the Tarim River, China.</span></p> <p><span>Both female and male leaves had the highest N resorption efficiency (NRE), then stems and roots last. We found sexual dimorphism in leaf nutrient resorption at Shaya, Luntai, and Yuli forest sites, where <em>P. euphratica</em> males had higher leaf NRE than females, whereas females had a higher leaf P resorption efficiency (PRE). Moreover, the different nutrient resorption strategies were related to leaf economics. <em>P. euphratica</em> males possess a conservation strategy with a higher leaf thickness, LMA, and leaf vein density, which positively correlated with leaf NRE, while females with higher leaf PRE resorbed disproportionately more P for the reproductive investment.</span></p> <p><span><em>P. euphratica</em> males possess a conservation strategy with higher leaf NRE, while females have higher leaf PRE for reproductive investment. Due to sexual spatial segregation across environmental gradients, dioecious plants are especially vulnerable to future climate change. The differences in nutrient uptake and utilization strategies between females and males may result in a situation where one sex is more prone to future climate change than the other one. Such sex-specific nutrient resorption strategies are associated with leaf economics. The present study deepens our understanding of the plant nutrient balance and adaptation strategies under climate change.</span></p>

Data from: Community-level economics spectrum of fine-roots driven by nutrient limitations in subalpine forests
1. Fine-root traits show remarkable variation with plant community structure and environmental shifts, but there is limited understanding of how trait covariation that exists among fine-root traits shifts among different communities, especially in forests. We explored links among the fine-root traits of forest communities to determine whether community root traits shift predictably according to an economics framework along environmental gradients. 2. Measurements of root morphology, nitrogen, phosphorus and carbon concentrations, and measures of standing root densities were collected on fine roots (diameter ≤ 2 mm) from 129 forest plots in five subalpine forests. 3. This study demonstrates an existence of a community-level fine-root economics spectrum (REScom) in the subalpine forests, in which specific root length was strongly and positively related to root nitrogen and phosphorusconcentrations, but negatively related to root diameter. Soil nutrient limitation was a major driver of the REScom as changes in soil [N], [P] and [C] contents were related to changes in SRL, root [N], root [P]. Variables related to standing fine-root length and mass were independent of the REScom and was primarily related to forest community structure, particularly in tree closure and herbaceous plant mass. 4. These results indicate two distinct functional dimensions of community fine-root trait variation: resource-use efficiency via changes in root structure and construction, and separately via changes in the standing root system. Identifying shifts in allocation to and investment in fine roots enhances our understanding of a root and whole-plant economics spectrum and community functioning.
