  1. Site 1: Alameda, S. alterniflora and hybrid shoreline meadow adults, mudflat hybrid adults.
  2. Site 2: Robert's Landing, adult hybrid shoreline meadow and mudflat.
  3. Site 3: Hayward, adult S. foliosa and hybrid shoreline plants.
  4. **Significance at P<0.0001. *Significance at P<0.05.
  5. Average F-statistics over all loci. Fixation indices: FIS, 0.05; FSC, 0.09; FCT, 0.08; FIT, 0.21. FIS, among individuals within populations; FSC, among adult populations but within sites; FCT, adult populations among sites; FIT, among adult populations and among sites.
