Figure 1 in Delimiting phylogeographic diversity in the genomic era: application to an Iberian endemic frog
Figure 1. Phylogeographic structure and diversity in R. parvipalmata based on RAD-seq analyses. The map (A) shows the location and numbering of sampled localities; the yellow shades outline the presumed distribution of the species. Barplots (B) and the PCA (C) display within-population expected heterozygosity He and between-sample genetic variation, both based on 812 unlinked SNPs. (D) The phylogenetic network shows genetic relationships among samples, based on ~155 kb sequences. Colour-coding follows a red-orange gradient that corresponds to the average genomic ancestries of samples/populations between the Galician R. p. parvipalmata T1 (red) and the Asturian R. p. asturiensis T2 (orange) lineages (Fig. 2). Triangles and squares highlight the isolated southernmost and westernmost samples/populations. The star shows the type locality and the holotype of R. p. asturiensis.

Figure 1. Map of the study area in the South Pacific of Costa Rica (1:1,250,000 scale and Coordinate Reference System (CRS) WGS84) for the analysis of the ecological niche of P. vittatus using data generated during 2020. Main towns are shown. Large protected areas are represented by their management category: 1: Corcovado National Park; 2: Piedras Blancas National Park; 3: Golfo Dulce Forest Reserve; 4: Paso de la Danta Biological Corridor.

Figure 3 in Remote sensing and citizen science to characterize the ecological niche of an endemic and endangered Costa Rican poison frog
Figure 3. Relative niche suitability for Phyllobates vittatus across its distribution in the South Pacific of Costa Rica. The suitability map was generated during 2020 through the combination of eleven different environmental predictors, with elevation, forest percentage, distance to lakes and distance to ASADAS explaining the greatest proportion of the variance. The legend shows niche suitability ranging from low suitability (0; white) to high suitability (1; dark green). We represent in white high-altitude areas (>1500 m) and large plantations identified during the classification of the land cover, which were not included in the model. This prediction was made with a model built using a 5 km buffer area around the known occurrence points. Large protected areas are represented by their management category: 1: Corcovado National Park; 2: Piedras Blancas National Park; 3: Golfo Dulce Forest Reserve; 4: Paso de la Danta Biological Corridor. Sources: Costa Rica Atlas 2014, Costa Rica Conservation Areas National System (SINAC) 2016 and 2020. This map is at a 1:1,150,000 scale and CRS WGS84.
