MAXENT reconstructions of Pleistocene Last Interglaciation (LIG) and Last Glacial Maximum (LGM), and present-day distributions. A) Reprojection of H. formosa ecological niche model (C) on paleoclimatic data layers representing LIG environments. B) Reprojection of H. formosa ecological niche model on colder/drier environmental conditions of the LGM, showing southward range contraction, possibly to 'microrefugia’. C) Present-day ecological niche model. Colors represent logistic ecological niche model scores and range from 0 (dark blue, indicating unsuitable subaerial areas) to 1 (100% bioclimatic suitability, thus higher predicted probability of species occurrence).
