Figure 2

Map of South America during the LGM displaying five connectivity patterns and one biogeographical disjunction of vegetation: Central South American Connectivity (CSAM), Northern Andes-Western Amazonian Connectivity (NAWA), Southern Atlantic Continental Shelf Connectivity (SACS), Eastern Andean Connectivity (EACO), Northeastern Atlantic Connectivity (NATC) and Southern Chilean Andes Disjunction (SCAD). Also shown are the overlapping potential LGM distributions of Araucaria, Arecaceae, Drimys, Ericaceae, Hedyosmum, Ilex, Myrsine, Myrtaceae, Podocarpus, Symplocos and Weinmannia (orange to white i.e. high to low suitability). In addition shown 54 pollen record sites (red dots). The LGM coastline is delimited by a red line, based on sea level ca. 120 m lower than present. The base maps are shaded relief images of the ETOPO1 Global Digital Elevation Model with 01-min spatial resolution, with custom hypsometric color scales. Raster shading and color scale creation were performed in GRASS-GIS 8.3 (https://grass.osgeo.org), map composition in QGIS 3.28 (https://qgis.org) and final artwork in Inkscape 1.3 (https://inkscape.org).
