FIGURE 5. Comparing beta diversities between grazed and grazing-excluded in the arid steppes rangelands of Algeria. Diversity was quantified using the Hill numbers, with q = 0 (all species are given equal weight), q = 1 (greater weight is given to common species), or q = 2 (greater weight is given to dominant species). “Beta transects GS” and “Beta transects GES” refer to among transects beta diversity (grain = transect and extent = site) in grazed and grazing-excluded steppes, respectively; “Beta sites GS” and “Beta sites GES” refer to among sites beta diversity (grain = site and extent = management type) in grazed and grazing-excluded steppes, respectively.
