Linking environmental stability with genetic diversity and population structure in two Atlantic Forest palm trees

We ask if Late Quaternary climatic stability predicts contemporary population structure and genomic-level diversity in two palm species: Syagrus botryophora and S. pseudococos. We i) describe the patterns of genomic variation in both species, ii) test how well the genomic variation is explained by isolation by distance (IBD) and by the environmental resistance imposed by the dynamic climates of the past (isolation by resistance; IBR) and iii) test for a correlation between genetic diversity and historical stability.
