Areas predicted as climate refugia, habitat gain, habitat loss, or unsuitable for F. quadrangularis under the IPCC SSP1–2.6 scenario (left) and the IPCC SSP5–8.5 scenario (right) are (A–B) by 2050 and (C–D) by 2100. Climate refugia are defined as areas that remain suitable under both present and future conditions; habitat gain refers to currently unsuitable areas that become suitable in the future, and habitat loss are suitable areas becoming unsuitable.
