Response of plant aggregations to management and soil conditions in the grassland (A) and in the savanna biome (B).

<p>For each plant aggregation, bars denote the proportion of explained variance (given as effect sizes, η²) in best-fitting linear models, associated with biome-specific principal components and land tenure. Parameters are ordered by their effect sizes, starting with the grazing-related principal component. Arrows facing upwards indicate a positive response to increased grazing, and arrows facing downwards indicate a negative response. Note that negative or positive responses to grazing cannot be assigned to ordination axes. DCA 1 = plot scores on first DCA axis.
