Fig. 4: Reconstructed ancestral area of the Cyrenidae species from BioGeoBEARS under BAYAREALIKE + J model.

From: Multiple origins of freshwater invasion and parental care reflecting ancient vicariances in the bivalve family Cyrenidae (Mollusca)

Fig. 4

Colored rectangles along the internal and terminal branches represent the ancestral biogeographic ranges and contemporary distribution of their native populations, respectively, corresponding to a world map categorized into five divisions of the continents: A East Asia, B India, C Australasia, D South America, and E North/Central America. For instance, the “ABC” at each internal node indicates that the ancestral biogeography includes East Asia (A), India (B), and Australasia (C).
