Between a rock and a soft place: surfgrass colonizes sediments without attachment to rock.

Keywords: anchoring; attachment; ecotype; habitat; plasticity; rhizome; root; seagrass; surfgrass Considering that rhizome extension in I P. serrulatus i is likely slow due to rhizome thickness (Marba and Duarte [6]), these bulbous anchors could be critical in stabilizing the establishing seedling recruits until they are able to build a stronger rhizome network via clonal growth. This assumption could be confounded by the longevity of I P. serrulatus i ramets in sediments (see Marba and Duarte [6]) or by the regional pattern indicative of the evolutionary and ecological history of I Phyllospadix i populations in soft-sediment habitats.
