Pushing the limits of C3 intrinsic water use efficiency in Mediterranean semiarid steppes: responses of a drought-avoider perennial grass to climate aridification [Dataset]
We investigated the variations in multiple plant traits in the perennial tussock grass Stipa tenacissima along an aridity gradient in Spain. Traits measured include leaf stable isotopes (δ18O, δ13C, δ15N), nutrient concentrations (N, P, K), and culm water content and isotopic composition (δ18O, δ2H)...

| Sumario: | We investigated the variations in multiple plant traits in the perennial tussock grass Stipa tenacissima along an aridity gradient in Spain. Traits measured include leaf stable isotopes (δ18O, δ13C, δ15N), nutrient concentrations (N, P, K), and culm water content and isotopic composition (δ18O, δ2H) of paired pure-grass and shrub-encroached S. tenacissima steppes along a 350 km aridity gradient in Spain (10 sites, 160 individuals). Here, we provide a summary of mean (± SE), minimum and maximum values of S. tenacissima traits for pure grass and shrub-encroached steppes at ten sampling locations. The blank cells for the variable "Plant cover" indicate that there are no maximum or minimum values per study plot, just a single overall value for each study plot. |
