Point of View
Cover Illustrations: Effects of river capture on macroevolutionary diversification (speciation, dispersal, and extinction) in fluvial taxa. T1–T3, time steps 1–3. A. Colored regions, river basins; watersheds, dispersal barriers. B. Changing patterns of area connectivity through time. Solid arrows indicate area identity or vicariance events; dashed arrows area identity or geodispersal events. C. Hypothetical phylogeny of fishes on the evolving landscape. Species indicated by letters, areas by numbers. Note at T2 concordant allopatric origin of species D in area 3 and range expansion of species C into area 3, such that C and D are sympatric but not sister species. Note also at T3 range expansion of species B into area 4, extirpation of species C from area 4, and extinction of range-restricted species D.
