cordgrasses in the genus Spartina have
become model organisms for studying biological invasions
from both ecological and genetic perspectives. Here we
characterize 11 disomic loci in Spartina
show promise for population studies and for studying
hybridization events between S. alterniflora and S. foliosa.
Comparisons among invasive and native S. alterniflora populations
showed that levels of allelic variation are lower in
invasive populations. In addition, nearly all loci that
amplified in S. foliosa populations
and in a swarm of S. alterniflora×foliosa hybrids
were polymorphic. We also found that several loci amplified
successfully in other Spartina species.
