Plate 11.4 (Fig. 11.4 on page 297) Results of a bioclimatic model for the plant Protea lacticolor in the Cape Floristic Region
of South Africa. Its current distribution is represented by red and green squares on the map. According to the modeled
climate change scenario, the species is predicted to persist in the green areas in 2050 but will be extinct in the red areas,
because here the future patterns of temperature and water availability will be beyond the plant's climatic envelope. Blue
squares represent new areas that could be inhabited by the plant provided their dispersal capabilities (or action by
conservation managers) can get them there. (From Hannah et al., 2005.)

Plate 11.6 (Fig. 11.6 on page 300) Predicted changes to distribution of the Argentine ant between now and 2050. The map
represents the average predictions of four global climate change scenarios. Red areas are those predicted to improve for
Argentine ants, whereas blue areas are predicted to worsen for the species. (After Roura-Pascual et al., 2004.)
