Data from: Nitrogen enrichment and warming shift community functional composition via distinct mechanisms: the role of intraspecific trait variability and species turnover
<p>1. Global change factors may shift community functional composition by driving species turnover (species occurrence and species relative abundance) and intraspecific trait variability. However, their relative contribution in determining the functional response of community to global change, especially nitrogen enrichment and warming, remains unclear.</p> <p>2. We conducted a fully factorial field experiment in a Tibetan alpine meadow to examine responses of plant community functional composition to nitrogen enrichment and warming by quantifying seven plant functional traits in each plot. Using the sum of squares decomposition, we further disentangled the relative contribution of intraspecific trait variability and species turnover to changes in community functional composition.</p> <p>3. We found that nitrogen enrichment caused a shift of plant community toward a more resource-acquisitive strategy, while warming resulted in a shift toward a more resource-conservative strategy. Plant intraspecific trait variability controls shifts in community functional composition in response to nitrogen enrichment, whereas species turnover (especially change in species relative abundance) mainly explains warming-induced shifts. Nitrogen enrichment and warming did not show significant interactive effects on plant functional composition.</p> <p>4. These findings suggest that nitrogen enrichment and warming can alter community functional composition of alpine meadow through distinct mechanisms. Plant intraspecific trait variability confers functional resilience of Tibetan alpine meadows under nitrogen enrichment, but warming could induce significant turnover of species that pronouncedly impacts community functioning in this highland ecosystem.</p>

Figure 3. Whole-plant recovery of 15N by each species expressed as a percentage of the total 15N applied. Values are means ± 1 SE (n = 5). Within a nitrogen (N) treatment, bars sharing the same letter are not significantly different (Tukey honest significant difference [HSD] test, α = 0.05). See Table 1 for list of full species names.
Figure 2 in Effects of nitrogen and phosphorus availability on the early growth of two congeneric pairs of savanna and forest species
Figure 2. The effect of our four treatments (Com: Complete Hoagland solution; -N: Solution without nitrogen; -P: Solution without phosphorus and -NP: Solution without both macronutrients) in the grow of a congeneric pair of species after 45 days of experiment. The boxes in the left side represent the savanna species (Enterolobium gummiferum), those on the right side, the forest ones (E. contortisiliquum).

Shrubland Species Cover, Biometric, Carbon and Nitrogen Data, Southern Idaho, 2014
This dataset provides the results of the characterization of shrubland vegetation at two study areas in southern Idaho, USA: the Reynolds Creek Experimental Watershed (RCEW) and Hollister. Data were collected in September and October 2014. In each study area, several 10-m x 10-m plots were randomly established that are representative of the local dominant vegetation types. Measurements are reported for both plot and individual shrub attributes. Plot measurements include shrub density and biometric data, percent shrub cover derived from line intercept transects, percent plant species and bare ground cover derived from photo analysis, and average LAI. Measurements for selected individual shrubs include height, width, length, number of stems, and LAI. Leaf samples were collected for determining LAI, specific leaf area (SLA), carbon and nitrogen concentrations, and isotopic nitrogen and carbon.
