Figure 1.
Distribution of the10% highest values of annual precipitation for the current time, the two last glacial maximum period (LGM), and the intersection of the three maps.
Symbols (in the intersection map) indicate the 44 sites in the southern range of Brazilian Atlantic Forest. Dark shading indicates stable regions. White circles represent sites in an unstable region (Quaternary Climatic Oscillations). White triangles represent sites in a stable region (Quaternary Climatic Stability). Abbreviations of each site as in Appendix S1 in File S1.
Figure 2.
Relationships between geographical distance and Compositional Beta Diversity (CBD, A = βjac, B = βjtu and C = βjne) and Phylogenetic Beta Diversity (PBD, D = UniFracTotal, E = UniFracTurn and F = UniFracPD) components.
Subplots are showing the proportion explained by turnover (βjtu/βjac and UniFracTurn/UniFracTotal) and nestedness (βjne/βjac and UniFracPD/UniFracTotal) components. Symbol colors indicate the region where the sites occur in the southern range of Brazilian Atlantic Forest. Black circles indicate dissimilarity between sites within stable region (Quaternary Climatic Stability). Gray circles indicate dissimilarity between sites within unstable region (Quaternary Climatic Oscillations). White circles indicate dissimilarity between unstable and stable sites (different regions).
Figure 3.
Partition of the variance of Compositional Beta Diversity (CBD, βjac, βjtu and βjne) and Phylogenetic Beta Diversity (PBD, UniFracTotal, UniFracTurn and UniFracPD) components explained by geographical distance (Space), current environmental gradients (Environ) and long-term climatic conditions (refugia) for 44 sites in the southern range of Brazilian Atlantic Forest.
Res = unexplained variance. “-” = variation explained <0.
Figure 4.
Relationship among Compositional Beta Diversity (CBD, A = βjac, B = βjtu and C = βjne) and Phylogenetic Beta Diversity (PBD, A = UniFracTotal, B = UniFracTurn and C = UniFracPD) components.
Symbol colors indicate the region where the sites occur in the Brazilian Atlantic Forest. Black circles indicate dissimilarity between sites within stable region (Quaternary Climatic Stability). Gray circles indicate dissimilarity between sites within unstable region (Quaternary Climatic Oscillations). White circles indicate dissimilarity between unstable and stable sites (different regions).
Figure 5.
Standardized effect size (SES) values for phylogenetic beta diversity (PBD, A = UniFracTotal, B = UniFracTurn and C = UniFracPD) components among 44 sites in Brazilian Atlantic Forest.
Values between dashed lines indicate that PBD components have no difference with respect to null expectation. Symbol colors indicate the region where the sites occur in the southern range of Brazilian Atlantic Forest. Black circles indicate SES between sites within stable region (Quaternary Climatic Stability). Gray circles indicates SES between sites within unstable region (Quaternary Climatic Oscillations). White circles indicate SES between unstable and stable sites (different regions).
