“…It should be noted that in our and other previous analyses, shared and pure effects of climate (and other inter-site variation) and species were not separated (He et al 2006a;He et al 2008;Reich and Oleksyn 2004;Wright et al 2005b). Thus, it was not clear from these analyses how much of the correlation between climatic variables and leaf traits was due to climate-induced species shifts among sites and how much to differences among populations of the same species occurring at different sites.…”

“…The climatic and soil properties of the three regions are presented in Table 1. The leaf trait data from the Tibetan Plateau (He et al 2006b), data on C:N:P stoichiometry (He et al 2006a;He et al 2008), and bivariate relationships between leaf productivity (mass-based photosynthetic rate, A mass , N and P concentrations, photosynthetic N-use efficiency, PNUE) and persistence (leaf mass per area, LMA) (He et al 2009) were presented previously.…”

“…The potential environmental drivers of leaf trait variation investigated in these broadscale studies included long-term average temperature, precipitation (Reich and Oleksyn 2004;Reich et al 1997;Wright et al 2004), irradiance (Niinemets 2001;Niinemets et al 1999;Wright et al 2006), life form variation and species identity (He et al 2006a;He et al 2008). …”

Although broad-scale inter-specific patterns of leaf traits are influenced by climate, soil, and taxonomic identity, integrated assessments of these drivers remain rare. Here, we quantify these drivers in a field study of 171 plant species in 174 sites across Chinese grasslands, including the Tibetan Plateau, Inner Mongolia, and Xinjiang. General linear models were used to partition leaf trait variation. Of the total variation in leaf traits, on average 27% is due to taxonomic or phylogenetic differences among species within sites (pure species effect), 29%to variation among sites within species (pure site effect), 38% to joint effects of taxonomic and environmental factors (shared effect), and 6.2% to within-site and within-species variation. Examining the pure site effect, climate explained 7.8%, soil explained 7.4%, and climate and soil variables together accounted for 11%, leaving 18% of the inter-site variation due to factors other than climate or soil. The results do not support the hypothesis that soil fertility is the "missing link" to explain leaf trait variation unexplained by climatic factors.Climate-and soil-induced leaf adaptations occur mostly among species, and that leaf traits vary little within species in Chinese grassland plants, despite strongly varying climate and soil conditions.

“…Based on the latitude and longitude of each sampling site, the monthly mean temperature and precipitation were calculated through Kriging interpolation [25]. Based on our previous studies [26,27], we used two climatic indices that have the highest explanatory power for ecological traits (i.e., growing season temperature and growing season precipitation).…”

Knowledge of the leaf anatomy of grassland plants is crucial for understanding how these plants adapt to the environment. Tibetan alpine grasslands and Inner Mongolian temperate grasslands are two major grassland types in northern China. Tibetan alpine grasslands occur in high-altitude regions where the low temperatures limit plant growth. Inner Mongolian temperate grasslands are found in arid regions where moisture is the limiting factor. Few comparative studies concerning the leaf anatomy of grassland plants of the Tibetan Plateau and Inner Mongolian Plateau have been conducted. We examined leaf characteristics at 71 sites and among 65 species, across the alpine grasslands of the Tibetan Plateau and the temperate grasslands of the Inner Mongolian Plateau. We compared the leaf structures of plants with different life forms and taxonomies, and their adaptation to arid or cold environments. We explored relationships among leaf features and the effects of climatic factors (i.e., growing season temperature and precipitation) on leaf characteristics. Our results showed that (i) there were significant differences in leaf anatomy between Tibetan alpine and Inner Mongolian temperate grasslands. Except for mesophyll cell density, the values obtained for thickness of leaf tissue, surface area and volume of mesophyll cells were larger on the Tibetan Plateau than on the Inner Mongolian Plateau. (ii) Within the same family or genus, leaf anatomy showed significant differences between two regions, and trends were consistent with those of whole species. (iii) Leaf anatomy of woody and herbaceous plants also showed significant differences between the regions. Except for mesophyll cell density, the values obtained for the thickness of leaf tissue, and the surface area and volume of mesophyll cells were larger in herbaceous than in woody plants. (iv) Leaf anatomical traits changed accordingly. Total leaf thickness, thicknesses of lower and upper epidermal cells, and surface area and volume of mesophyll cells were positively correlated, while mesophyll cell density was negatively associated with those traits. (v) Growing season temperature had stronger effects on leaf anatomy than growing season precipitation. Although the communities in Tibetan and Inner Mongolian grasslands were similar in appearance, leaf anatomy differed; this was probably due to the combined effects of evolutionary adaptation of plants to environment and environmental stress induced by climatic factors.

Nitrogen increased aboveground biomass of Leymus chinensis grown in semi‐arid grasslands of inner Mongolia, China

There is controversy over whether the addition of nitrogen (N) is the key to the rapid growth of Chinese rye grass Leymus chinensis (Trin.) Tzvel. in natural, semiarid grasslands. We investigated yearly impact of various N additions (0, 91, 183, and 274 kg N ha−1) on the relationships between nutrient traits (plant carbon [C], N, and phosphorous [P]), morphological traits (plant height, leaf number, leaf length, leaf width, stem length and stem diameter) and aboveground biomass in L. chinensis. Results showed that most of the growth characteristics of L. chinensis increased with N rate except for leaf number and stem length. Nitrogen addition increased aboveground biomass, plant height, leaf length and stem length of L. chinensis, which was related to high precipitation during the critical period for the growth of L. chinensis. Nitrogen addition increased the N concentration and N to P ratio of L. chinensis tissue, but decreased the C to N ratio in the leaf and stem of L. chinensis. Compared to the control, N addition increased C and N concentrations and the N to P ratio, but decreased P concentration and the C to N ratio.
