Ancient vicariance or recent long-distance dispersal? Inferences about phylogeny and South American-African disjunctions in rapateaceae and bromeliaceae based on ndhF sequence data
Download2004
Evans, T.M., Sytsma, K.J., Givnish, T.J., Berry, P.E., Hall, J.C., Pires, J.C., Millam, K.C.
Rapateaceae and Bromeliaceae each have a center of diversity in South America and a single species native to a sandstone area in west Africa that abutted the Guayana Shield in northern South America before the Atlantic rifted. They thus provide ideal material for examining the potential role of...

Phylogenetic Relationships and Biogeography of Fuschia (Onagraceae) Based on Noncoding Nuclear and Chloroplast DNA Data
Download2004
Hahn, W., Mast, A.R., Hall, J.C., Berry, P.E., Sytsma, K.J.
To examine relationships and test previous sectional delimitations within Fuchsia, this study used parsimony and maximum likelihood analyses with nuclear ITS and chloroplast trnL-F and rpl16 sequence data for 37 taxa representing all sections of Fuchsia and four outgroup taxa. Results support...

Urticalean Rosids: Circumscription, rosid ancestry, and phylogenetics based on rbcL, trnL-F, and ndhF sequences
Download2002
Conti, E., Nepokroeff, M., Chase, M.W., Pires, J.C., Morawetz, J., Zjhra, M., Hall, J.C., Sytsma, K.J.
To address the composition of the urticalean rosids, the relationships of the component families (maximally Cannabaceae, Cecropiaceae, Celtidaceae, Moraceae, Ulmaceae, and Urticaceae) and analyze evolution of morphological characters, we analyzed sequence variation for a large sampling of these...
