Table 3 Percentage overlap between different hotspot criteria using the 5% most species-rich grid cells

From: Hotspot analysis of Taiwanese breeding birds to determine gaps in the protected area network

  Total species richness Endemic species richness Threatened species richness Rare species richness
Total species richness - 512 (1.4%, 34.8%, 33.7%) 742 (2.1%, 50.4%, 47.1%) 58 (0.2%, 3.9%, 25.3%)
Endemic species richness 1,356 (3.8%, 51.2%, 61.6%) - 832 (2.3%, 54.8%, 52.8%) 91 (0.3%, 6.0%, 39.8%)
Threatened species richness 1,474 (4.1%, 72.4%, 67.0%) 1,691 (4.7%, 83.1%, 63.9%) - 189 (0.5%, 12.0%, 82.5%)
Rare species richness 948 (4.6%, 33.2%, 43.1%) 1,881 (5.2%, 65.9%, 71.1%) 1,263 (3.5%, 44.2%, 62.0%) -
  1. In each cell, the number of grid cells which overlapped for both hotspot criteria given in the row and column is given. In the following parentheses, we calculated the percentage for this number divided by (1) the total number of grid cells of the study area (36,022 grid cells), (2) the number of grid cells falling into the hotspot criterion in the row, and (3) the number of grid cells falling into the hotspot criterion in the column. To the upper right of the diagonal, this calculation was done for grid cells which were determined to be the 5% most species-rich grid cells within the entire study area (Table 1, Figure 6), and to the lower left of the diagonal, the calculation was done for grid cells which were determined to be the 5% most species-rich grid cells outside of protected areas (Table 1, Figure 7).
