Genetic variation among populations of Valeriana ciliata T.&G. (Prairie valerian) in midwestern prairie fens1
lations of V. ciliata in Ohio. These southern, edge-of-range populations were compared with genetic variation in four Michigan populations at the middle of this species' range. Allozyme electrophoresis of individuals in populations of this subdioecious species revealed overall levels of genetic diversity (Hes = 0.245) that were higher than expected for an endemic. Though small in size, the two Ohio populations of V. ciliata had intermediate levels of genetic diversity (He = 0.224, 0.254) in comparison to the Michigan populations (He = 0.0540.305). Differences between census population size and effective population size, uneven sex ratios, location within the species' range, and variation in habitat quality all contribute to the level of genetic variation recorded among these V. ciliata populations.
期刊介绍：
The Journal of the Torrey Botanical Society (until 1997 the Bulletin of the Torrey Botanical Club), the oldest botanical journal in the Americas, has as its primary goal the dissemination of scientific knowledge about plants (including thallopyhtes and fungi). It publishes basic research in all areas of plant biology, except horticulture, with an emphasis on research done in, and about plants of, the Western Hemisphere.
