As model organisms
for studying biological invasions, Spartina cordgrasses
are subjects of many current ecological and evolutionary
investigations. Here we characterize an additional 24 disomic
loci in Spartina
alterniflora for investigating Spartina population
genetics and systematics, as well as the recent hybridization
between S. alterniflora and S. foliosa .
Further evaluation of allelic variation in S. foliosa shows
species-specific alleles and lower levels of polymorphisms
than previously reported. Allelic variation is again lower
in invasive Pacific coast populations of S. alterniflora than
in native Atlantic/Gulf coast populations. Most loci also amplified
successfully in S. densiflora.
