Fig. 4 in Broadly Distributed but Genetically Fragmented: Demographic Consequences of Pleistocene Climatic Oscillations in a Common Iberian Grasshopper

Fig. 4. Principal component analysis (PCAs) of genetic variation for populations of the Pantel's grasshopper (Omocestus panteli). Analyses are based on a dataset of 14,454 SNPs. Colors correspond to the genetic cluster at which populations were predominantly assigned according to STRUCTURE analyses for K = 6 (Fig. 3). Population codes as described in Table 1. Inset image shows a male of Omocestus panteli (photo by Pedro J. Cordero).
