Conservation Genetics of Nabalus serpentarius and its Common Congener,Nabalus trifoliolatus (Asteraceae).

Nabalus serpentarius (Pursh) Hooker is a species of concern to conservation management on the island of Nantucket in Massachusetts where four populations have been recently observed. Funding and personnel may be limited so it is best to understand which populations need the most attention to construct a management plan that effectively protects the species on the island. Nuclear DNA was extracted from leaf tissue collected from N. serpentarius and N. trifoliolatus (common congener) on the island. Transferability of Taraxacum sp. markers was tested with the samples of the two Nabalus species and Nabalus specific primers were developed from sequence data for N. serpentarius. Both sets of primers were used to genotype individuals of both Nabalus species collected on Nantucket. N. serpentarius shows no reduction in population genetic variation as compared to the common congener, and the two species demonstrate similar and very low levels of population genetic structure. These data indicate that population genetic threats to the rare species are not an immediate concern. However, given the small numbers of populations and the potential for stochastic demographic threats to them, we recommend protection of all populations. Further, the low levels of population genetic structure among populations could indicate transplants from one population to another would be successful though common garden experiments to investigate the potential for local adaptation would be an important next step.
