Covariations and tradeoffs of phosphorus (P) acquisition strategies in dioecious Populus euphratica as affected by soil water availability
<p>1. Dioecious species may be particularly vulnerable to climate change because they often exhibit skewed sex ratios that are reinforced by the physiological and biological specialization of each sex to specific microhabitats. Yet, it is unclear how differences in functional traits between female and male plants lead to sex-specific responses to drought and whether these responses are associated with phosphorus (P) acquisition diverge or converge.</p> <p>2. Here, we measured the morphological and physiological traits of roots, and the functional microorganisms related to P acquisition in <em>Populus euphratica</em> females and males in the rhizosphere under different water availability.</p> <p>3. The specific root length of females was greater than that of males, regardless of soil water availability. Therefore, the P concentration of females was significantly higher than that of males under well-watered conditions. In contrast, the physiological adjustment to drought showed distinct sexual patterns: males significantly increased the foliar manganese concentration and maintained higher acid phosphatase activities in the rhizosphere. Moreover, the arbuscular mycorrhizal hyphal biomass was reduced less in males than in females under water deficiency. Soil water shortage also decreased the α diversity of phosphate solubilizing bacteria (PSB) and changed the co-occurrence network in the rhizosphere of females, but it had little effect on males. Therefore, the favorable physiological processes and effective maintenance of functional microbial homeostasis in the rhizosphere were the reasons that enabled males to reduce P loss in leaves under water deficiency.</p> <p>4. Our study indicated that, within<em> P. euphratica</em> populations, covariations and tradeoffs simultaneously occurred among the three groups (root morphology, physiology, and functional microorganisms) of functional traits evaluated. More generally, the assessment of variations in sex-specific P acquisition strategies may help to understand the causes of sex ratio bias and how <em>P. euphratica</em> males and females mitigate resource shortage.</p>
Comparison of the nutrient resorption stoichiometry of Quercus variabilis Blume growing in two sites contrasting in soil phosphorus content
<p>The databases provided here support the statistical analyses of the manuscript “Comparison of the nutrient resorption stoichiometry of <em>Quercus variabilis</em> Blume growing in two sites contrasting in soil phosphorus content” (Annals of Forest Science). The dataset is provided in Microsoft Excel format. The dataset (2015 data) contains information about concentrations of N, C, P, K, Ca, Mg, Fe, Mn, Zn, Cu, Al, and Na (mg g<sup>-1</sup>), ratios of C:N, N:P, and C:P on molar basis in soils, green leaves, and senesced leaves, and their resorption efficiencies and resorption efficiency ratios calculated as log<sub>e</sub>(C<sub>RE</sub>/N<sub>RE</sub>), log<sub>e</sub>(N<sub>RE</sub>/P<sub>RE</sub>) and log<sub>e</sub>(C<sub>RE</sub>/P<sub>RE</sub>) by leaves of <em>Q. variabilis</em>, and also leaf mass per area (mg cm<sup>-2</sup>), total height (m) and diameter at breast height (cm) of the<em> Q. variabilis</em> at P-rich and P-deficient sites, in subtropical China. These data were used to assess differences in nutrient concentrations and the C:N, N:P, and C:P molar ratios of green leaves, senesced leaves, and soils, as well as variations in foliar nutrient resorption efficiencies and resorption efficiency ratios between P-rich and -deficient sites, and to assess the relationship between resorption, and soil or leaf chemistry, and the relationship between LMA and nutrient concentrations or resorption, across P-rich and -deficient sites.</p>
Data from: Plastic responses of belowground foraging traits to soil phosphorus-rich patches across 17 coexisting AM tree species in a subtropical forest
<p><span>1. </span><span>Belowground plastic responses to soil nutrient "hot-spots" form a key nutrient foraging strategy of plants coexisting in natural ecosystems. However, it is unclear how plant species differ in these belowground plastic responses and how they co-vary.</span></p> <p><span>2. </span><span>Plastic responses to soil phosphorus (P)-rich patches of absorptive root, mycorrhizal, and exudation traits of 17 co-existing arbuscular mycorrhizal (AM) tree species in a subtropical evergreen broad-leaved forest were investigated using a root bag method.</span></p> <p><span>3. </span><span>There was considerable variation and heterogeneity in species-specific responses to P-rich patches. Negative log response ratios usually occurred for high-cost traits and positive log response ratios for low-cost traits. There were tradeoffs in the plastic responses between root acid phosphatase activity and extraradical hyphal length, which were unaffected by phylogeny, and between root acid phosphatase activity and specific root length. Thicker-rooted species responded to P-rich patches more through root exudation plasticity than mycorrhizal plasticity. Thinner-rooted species relied more on mycorrhizal plasticity.</span></p> <p><span>4. </span><em><span>Synthesis</span></em><span>. Our results revealed diverse P foraging strategies comprising different combinations of plastic adjustments in absorptive root, mycorrhizal, and exudation traits among coexisting AM tree species, which suggest the potential for complementary exploitation of different soil P sources.</span></p>
