Fig. 2From: Experimental herbivore exclusion, shrub introduction, and carbon sequestration in alpine plant communitiesMean standing biomass of functional groups in plots with and without herbivore exclosure and plots with and without Salix transplants. The biomass was estimated from vegetation analysis and harvest performed on harvest plots during mid-growing season for alpine Empetrum-heath, meadow and Salix-shrub plant communities in the Dovre Mountains, Central Norway. We used parametric bootstrapping with 1000 replicates to get model estimates of biomass. Model performance and estimates with 95% confidence intervals are available in Additional file 3: Table S1 and Figure S3 respectivelyBack to article page
