Figure 3. Distributions of P. americana in red and P. pennsylvanica in
blue. The top row depicts predicted current (1970-2000) distributions
with occurrence points. The second and third row shows projected for
2050 and 2070 respectively at RCP8.5, with the lighter shades of blue
and red indicate previously suitable habitats becoming unsuitable, and
the darker shade of blue and red indicate previously unsuitable habitats
becoming suitable.
Table 1. The percentage of change
of suitable habitat under different representative concentration pathway
(RCP) trajectories in comparison to current predicted distributions.
