From: How do invasive trees impact shrub layer diversity and productivity in temperate forests?
Results of non-metric multidimensional scaling (NMDS) of shrub layer aboveground biomass proportions among species in each study plot (n = 168), colored by forest type. NMDS stress = 0.1638. Labels represent species scores occurring in at least five study plots (alien species marked by red labels), abbreviated to the first three letters of each part of a binomial name (e.g., Fag.syl = Fagus sylvatica)
