Plant Parents: Divide, Seed, and Conquer

By Kari St.Laurent ⋅ May 6, 2016 ⋅ Post a comment

Phragmites is the ultimate parent in terms of reproductive success, allowing it to increase in area by 25% since 1971 in the Rhode River subestuary. While phragmites can spread asexually through rhizome clones, seed dispersion requiring two parents was the most successful tactic found in this study. Kari St.LaurentI received a Ph.D. in oceanography in […]
