Risk screening scores for the non-native fish species screened with the AS-ISK: (A) basic risk assessment (BRA) for Yunnan Province; (B) BRA plus climate-change assessment (BRA+CCA) for Yunnan Province; dashed lines indicate thresholds for different intrusion risk levels (see thresholds in Table 2)

Fig. 4 in Distributions and phylogeographic data of rheophilic freshwater fishes provide evidences on the geographic extension of a central-brazilian amazonian palaeoplateau in the area of the present day Pantanal Wetland

Fig. 4. Haplotype network showing the occurrence of three groups (upper rio Xingu, upper rio Paraguay and upper rio Tapajós). Traces show the number of mutational steps from two adjacent haplotypes. Circle diameters are proportional to the number of individuals, which each haplotype and the colors represent the locality were those haplotypes were found. Upper rio Xingu= Pink (1: dark pink); upper rio Paraguay = Blue (2: light blue; 3: navy blue; 4: dark blue; 5: light pink; 6: orange; 7: light purple; 8: dark purple; 9: white; 10: yellow; 11: light green; 12: dark green); and upper rio Tapajós= Gray (13: light gray and 14: dark gray).

Hypothesized changes in the course of the Orinoco River in Venezuela and how they may have influenced the formation of major watersheds within the country follow Rod (1981), Díaz de Gamero (1996), and Lundberg et al. (1998). Major river basins in Venezuela are depicted in Fig. 1. (*) indicates simpatry.
