HOUSTON, HEATHER J.* AND TOM A. RANKER. Department of Environmental, Population and Organismic Biology, University of Colorado, Boulder, CO 80310-0334. - Population genetics of Sadleria cyatheoides (Blechnaceae), a Hawaiian endemic.
Population genetic analyses were conducted on the endemic Hawaiian
fern Sadleria cyatheoides (Blechnaceae) using Amplified
Fragment Length Polymorphisms (AFLPs). Populations were examined to
reveal levels and patterns of genetic diversity within and among
populations and within and among islands of the Hawaiian archipelago.
DNA was extracted from frozen isozyme grindate and utilized in the
AFLP technique to allow greater discrimination between individuals.
When compared to data obtained for the same individuals with isozyme
electrophoresis, finer patterns of genetic structure were evident with
Key words: Blechnaceae
