Figure 1. Maps of the Brazilian coast. (A) Present time. Different colors indicate different phylogeographic Regions I-IV. Political states identified as their official 2-letter code. = mouth of major rivers. = Vitória-Trindade seamount chain. = Cabo Frio upwelling system. = Cassino beach, the longest sandy beach in the southern hemisphere. SEC = South Equatorial Current. (B) Current and past coastline during Pleistocene glacial maxima with sea level 100 meters lower than present time. Bathymetry legend corresponds to figure 1B only. Boundary current according to R. Peterson & Stramma (1991).
Figure 2. Number of molecular-driven marine phylogeography papers published between 1987 and 2019 that minimally addressed Brazil’s marine biota.
Figure 3. Percentage of number of molecular-driven marine phylogeography papers published between 1987 and 2019 that minimally addressed Brazil’s marine biota according to (A) types of genetic markers (fragment analysis stands for ddRAD, RAPD, ISSR, AFLP, and RFLP techniques), (B) taxonomic groups, (C) functional forms and, (D) marine habitat.
Figure 4: Generalized linear model applied of the frequency of putative barriers to gene flow occurrences for populations of marine species recorded along the Brazilian coast (in latitudes). Data collected from articles contained new molecular data published between 1991 and 2019 with sample sites within the Brazilian coast.
Figure 5: Generalized additive model for the frequency of putative barriers to gene flow occurrences for populations of marine species sampled along the Brazilian coast. Data collected from phylogeography papers published between 1991 and 2019. Roman numbers stands for each of the four phylogeographic regions recognized in this model.
Figure 6: Phylogeographic break frequency at phylogeographic Regions I-IV identified in the generalized linear model depicted in Figure 5. The line within the box marks the median. The boundary of the box indicates the 25th and 75thpercentiles. Vertical line indicate the 10th and 90th percentiles. Whiskers above and below the box indicate outliers outside the 10th and 90th percentiles. Different letters above the box indicate statistically significant differences (p < 0.05).
Figure 7: Generalized additive models for the frequency of putative barriers to gene flow frequencies for populations of different marine taxa recorded along the Brazilian coast. Data collected from phylogeography papers published between 1991 and 2019 with sample sites within the Brazilian coast. A) Fishes, B) Crustaceans, C) Mollusks and, D) Cnidarians. Images represents an example of each taxonomic group. Graphs were designed using resources from flaticon.com.
