Table 1.
Proportion of species suitable climate space in the protected areas.
Mean percentage of species suitable climate space that is covered by the existing protected areas for the three taxonomic groups for both time periods studied. The value of proportion is calculated dividing the number of cells of the projected species suitable climate space inside the existing PA’s by the total number of cells of the projected species suitable climate space.

Current Protected areas and total number of species per cell for the three taxonomic groups in São Miguel and Terceira Islands for the 1961–1990 and 2080–2099 time periods.
Table 2.
Mean loss of suitable climate space within protected areas for the three taxonomic groups for both time periods.
The loss of species suitable climate space within the current PA’s is calculated as the difference between the number of cells of species suitable climate space for the 2080–99 period and the 1961–90 period over the total number of cells of the PA.
Table 3.
Efficiency of the current protected areas considering the projected distributions of all three taxonomic groups.
The taxonomic groups were considered together and separately using the Minimum set and Maximum coverage scenarios for both the 1961–90 and 2080–99 time periods. Minimum set values are a ratio between PRION output values for costs for the quasi-optimal solution and the current PA. Maximum coverage values are a ratio between the PRION output values for the targets of the quasi-optimal solution and the current PA. Efficiency is measured as the ratio between the existing PA’s and quasi-optimal solutions found by the software. The closer to 1 the values are, the more efficient the current PA’s are, as compared to the quasi-optimal solution found by the software.

Minimum Set—quasi-optimal solution that minimized the protected number of cells while protecting the same average proportion of each species’ range. Maximum Coverage—the optimal solution that maximized species coverage with similar costs.
