Members of the Chrysanthemum-complex include important floricultural (cut-flower) and
ornamental (pot and garden) crops, as well as plants of culinary, medicinal and (ethno) …

Rare species are typically considered to maintain low levels of genetic variation, and this
view has been supported by several reviews of large numbers of isozyme studies. Although …

All organisms must find and consume resources to live, and the strategies an organism uses
when foraging can have significant impacts on their fitness. Models assuming optimality in …

Wyethia reticulata is an edaphic endemic in the Sierra Nevada foothills. Its sympatric
congener, W. bolanderi, is also restricted to the foothills, but has a north–south range of 275 …

The spatial distribution of clonal versus sexual reproduction in plant populations should
generally have differing effects on the levels of biparental inbreeding and the apparent …

Adaptive evolution is often associated with speciation. In plants, however, ecotypic
differentiation is common within widespread species, suggesting that climatic and edaphic …

Random amplified polymorphic DNA (RAPD) analysis was used to assess the level of
genetic diversity in an endangered plant Cerastiumfischerianum var. molle and the …

Electrophoretic analysis of 18 allozyme loci was used to estimate the levels and structuring
of genetic variation within and among natural populations of the protected endemic palm …

Allozyme diversity and genetic divergence were estimated for eight populations within
Sarracenia purpurea. Two populations of each infraspecific taxon (ie, subsp. purpurea, and …

The Alaskan endemic shrub Dryas octopetala ssp. alaskensis and its circumpolar
conspecific ssp. octopetala are adapted to closely adjacent habitats in alpine areas of …
