AFLP fingerprinting, nrDNA sequencing, and HPLC of phenolic compounds from bark samples was used to assess the intensity of hybridisation in two mixed stands of Salix alba, S. fragilis, and their hybrid S. × rubens (Salicaceae) along the Danube in the vicinity of Regensburg (SE Germany). AFLP analyses of 130 individuals from two mixed and two pure strands(More)
Duckweeds, the fastest growing angiosperms, are gaining increasing attention with respect to their practical applications. Different clones of the same duckweed species vary in their physiological properties. Hence, screening of suitable clones of a species is very important. To enable the identification of clones, a clear taxonomic classification and(More)
The genus Tanacetum L. consists of around 160 species of the Compositae-Anthemideae. It holds a crucial position for understanding the phylogeny of the tribe and its subtribal and generic classification. The present study focuses on the phylogenetic relationships of the species and aims at a discussion of the infrageneric classification and boundaries of(More)
Hybridisation is an important evolutionary process. The investigation of hybridisation along elevational gradients, with their steep abiotic and biotic clines, provides insight into the adaptation and maintenance of species in adjacent habitats. The rare Senecio hercynicus and its spreading congener S. ovatus are vertically vicariant species that show(More)
To reconstruct the evolutionary history of the polyploid southern and central European genus Leucanthemum, comprising 41 species with ploidy levels ranging from 2x to 22x, we analysed chloroplast DNA sequence variation (psbA-trnH and trnL-trnF intergenic spacer regions) of 106 representatives belonging to 30 species and 41 taxa. In an unrooted haplotype(More)
