Maxent model results.
Fig 1.
Modeled habitat suitability on the island of Borneo for the lowland species Nepenthes rafflesiana, using Maxent (n = 139 localities).
Habitat suitability is presented for the periods 1960–1990 (left panel), 2011–2040 (second panel), 2041–2070 (third panel), and 2071–2100 (right panel). Model results are overlaid onto an elevation map for illustration purposes. Probability of habitat suitability, ranging from 0 to 1, is plotted on a color scale, with orange representing values of 0.3–0.4, and dark blue representing values of 0.9–1. Areas with < 30% probability of habitat suitability are not illustrated. Inset boxes show higher resolution maps for areas of high occurrence. Scale bar refers to center row of images.
Fig 2.
Modeled habitat suitability on the island of Borneo for the montane species Nepenthes tentaculata, using Maxent (n = 52 localities).
Habitat suitability is presented for the periods 1960–1990 (left panel), 2011–2040 (second panel), 2041–2070 (third panel), and 2071–2100 (right panel). Model results are overlaid onto an elevation map for illustration purposes. Probability of habitat suitability, ranging from 0 to 1, is plotted on a color scale, with orange representing values of 0.3–0.4, and dark blue representing values of 0.9–1. Areas with < 30% probability of habitat suitability are not illustrated. Inset boxes show higher resolution maps for areas of high occurrence. Scale bar refers to center row of images.

Projected changes in important Bioclim variables on the island of Borneo identified in Table 1.
Images represent changes in Bioclim variables relative to the 1961–1990 climate surfaces, projected to 2040, 2070, and 2100. Changes in temperature variables (Bio6, Bio10, and Bio11) are presented as °C; changes for precipitation variables (Bio12, Bio16) are presented as percentages.

Predicted net % change in area of climatically-suitable habitat relative to the 1961–1990 climate surfaces, for the periods 2011–2040, 2041–2070, and 2071–2100 for N. rafflesiana and N. tentaculata.
