A preliminary phylogeny of the 'didymocarpoid Gesneriaceae' based on three molecular data sets: Incongruence with available tribal classifications.
It is shown that all available classifications in Old World Gesneriaceae are artificial and do not reflect natural relationships, and consistent topological relationships can be retrieved from data sets with missing data using subsamples and different combinations of gene sequences. Expand

The evolution of fleshy fruit within Cyrtandra provided an adaptation for colonization throughout the oceanic Pacific via bird dispersal from a single common ancestor. Expand
Neophytes in Austria: Habitat preferences and ecological effects
Alien species are acknowledged as a major threat to the conservation of global biodiversity (e.g. Sala et al. 2000; McNeely et al. 2001; Cronk & Fuller 2001; Sukopp 2002; Cox 2004). While detailed… Expand
Evolution of resupination in Malagasy species of Bulbophyllum (Orchidaceae).

- 1 October 2007
This work investigated the evolution of resupination in a representative sample of these species by first reconstructing a combined nrITS and cpDNA phylogeny for a sectional reclassification and then plotting the different types of inflorescence development, which correlated well with main clades.

PHYLOGENY OF SOME SPECIES OF CYRTANDRA (GESNERIACEAE) INFERRED FROM THE ATPB/RBCL CPDNA INTERGENE REGION
The data suggest that the Samoan species included in this study originated by at least two independent colonization events, while for the Hawaiian species the situation is not clear yet. Expand
