Abstract Background In the United States and Canada, ca. one-half of native orchid species are now threatened with extinction. A number of these species are restricted to tallgrass prairies of central North America, such as the Eastern Prairie Fringe

Polyploidy may promote diversification by generating reproductive isolation between ploidy levels, but this reproductive barrier may not be absolute. Several recent analyses of diploid–tetraploid contact zones have found evidence for hybridization.

In taxa with few diagnostic characters, highly variable populations pose a major challenge to delimiting species. This is especially true in Dodecatheon (Primulaceae), which has a notoriously complex taxonomic history. Previous biosystematic studies

Th e evolution of increased competitive ability (EICA) hypothesis provides a compelling explanation for the success of invasive species. It contends that because alien plants have escaped their coevolved natural enemies, selection pressures favor a d

With the advent of PCR and DNA sequencing, DNA data have been widely applied to the assessment of relationships among taxa of recent origin (e.g., island endemics). Numerous recent studies have used DNA sequence data and/or cpDNA RFLPs to reconstruct

Random Amplified Polymorphic DNA (RAPD) markers were used to measure genetic diversity within and divergence among species of Dendroseris (Asteraceae: Lactuceae), a genus endemic to the Juan Fernandez Islands, Chile. Results were compared to previous

Aster furcatus is a rare, self-incompatible plant with fewer than 50 known populations throughout its range. We verified self-incompatibility in A. furcatus by conducting experimental self- and cross-pollinations and by examining seed set in a small

Sequences from the internal transcribed spacer region of nuclear ribosomal DNA (ITS) for 35 taxa of Coreopsis and 15 species of Bidens were used to hypothesize phylogenetic relationships within and between the two genera. Coreopsis is paraphyletic an
