1. Plant chemical and structural defence compounds are well known to impact upon herbivory of fresh leaves and influence decomposition rates after leaf senescence. A number of theories predict that alleviating nutrient limitation and reducing other environmental stressors will result in decreased production of plant chemical defences. 2. In this study, we measured plant defence properties [total polyphenols (TP), condensed tannins (CT) and lignin concentrations, and protein complexation capacity (PCC)] in both fresh and senesced plant leaves in a fully factorial N and P fertilization experiment set-up at each of three elevations along an elevational gradient in Swedish subarctic tundra heath vegetation. Further, we performed a decomposition of variance analysis on community-weighted averages (CWAs) of plant defence properties to determine the relative contributions of interspecific and intraspecific variation to the total variation observed in response to elevation and nutrient addition. 3. We hypothesized ... : Foliar defence/nutrient, soil abiotic, and vegetation community data from subarctic tundra heath fertilization experimentContains data from a fertilization experiment in subarctic heath vegetation from near Abisko, Sweden. Data are soil abiotic properties, vegetation pinpoint hits, and plant foliar defence compounds/foliar nutrients. All units and coding is contained within the file.
