Gene flow and species cohesion following the spread of Schiedea globosa (Caryophyllaceae) across the Hawaiian Islands
Island radiations are often regarded as natural laboratories that allow us to study evolution in action. The genus Schiedea (Caryophyllaceae) is one of the largest radiations of angiosperms in the Hawaiian Islands, and Schiedea globosa is one of the few species in the genus to be found on more than one of the main islands. DNA sequences from nineteen nuclear and three chloroplast regions show a pattern of colonization from older to younger islands (west to east), with a concomitant decrease in...[Show more]
