Use of Spatial Analysis to Test Hypotheses on Plant Recruitment in a Hyper-Arid Ecosystem
Figure 2
Study area with R. stricta patches displayed as discs.
To make all unbranched individuals visible in this figure, they were enlarged to discs of 0.25(i.e. all branched individuals) are displayed proportional to their actual surface area. A grid with square plots with sides five times the diameter of the largest observed nebkha (5×4.2 m = 21 m) is overlain over the site. Only cells with white background completely fall inside the study site. Gray plots were omitted from the calculations. A second grid with cell sides ten times the diameter of the largest observed nebkha (10×4.2 m = 42 m) is also overlain. The sides of these grid cells (8 in total) are depicted in bold.
