It is widely assumed that population size significantly affects the dynamics of plant populations. Smaller populations are threatened by genetic drift and inbreeding depression, both of which may result in a decrease of genetic variation and a resulting negative impact on plant fitness. In our study we analysed the patterns of random amplified polymorphic(More)
Eight populations of Aster tripolium (Compositae) and six of Salicornia ramosissima (Chenopodiaceae) from inland, naturally salt-contaminated habitats and anthropogenic salt-polluted sites in central Germany (Thuringia, Anhalt-Saxony) were analysed using random amplified polymorphic DNA (RAPD) markers to investigate the patterns of genetic variation. In(More)
Justicia areysiana Deflers (Acanthaceae) is an endemic shrub of the monsoon affected coastal mountains of the southern Arabian Peninsula with ballochorous seed dispersal. Its occurrence in a vegetation belt of relics of the (semi)-evergreen Afro-montane woodland characterised by Olea europaea subsp. cuspidata and Juniperus procera above an elevation of c.(More)
Random amplified polymorphic DNA (RAPD) fingerprinting was used to study species boundaries in six closely related NE Turkish Lilium (Liliaceae) taxa of the section Liriotypus. The investigated taxa were L. ciliatum, L. akkusianum, L. ponticum, L. kesselringianum, L. armenum, and L. szovitsianum. Of the 108 primers screened, 11 provided polymorphic and(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)
 Phylogenetic relationships in Primulaceae were investigated by analysis of nuclear rDNA ITS sequences. Thirty-four species of Primulaceae, two of Myrsinaceae and four outgroup taxa were analyzed. In accordance to the results of recently published papers on the phylogeny of Primulaceae we found the family to be paraphyletic and resolved the positions of(More)
Twenty-nine genera of the tribe Anthemideae (Compositae) (111 genera, ca. 1,800 species) are either restricted to or have their distributional centre in the S hemisphere. We here present a phylogenetic study based on nrDNA ITS and cpDNA ndhF sequence variation for a complete generic sampling of this S hemisphere group of the tribe with its paramount(More)
Introgressive hybridisation between Senecio hercynicus and Senecio ovatus (Compositae, Senecioneae) was studied in a mixed stand of the two species on the S- and SW-facing slopes of the German part of the Bohemian Forest (SE Germany). Morphological variation based on multivariate analysis of 14 diagnostic characters, along with genetic data from an(More)
In order to evaluate the phylogenetic relationships and taxonomic classification of the Iranian endemic Tanacetum paradoxum Bornm. (Asteraceae, Anthemideae), a molecular analysis based on nrDNA ITS sequences of 16 species of Tanacetum together with representatives of 27 genera of subtribes Artemisiinae and Handeliinae as well as a micromorphological study(More)
Mixed stands of Senecio ovatus subsp. ovatus and S. germanicus subsp. germanicus occur in the colline belt of central and eastern Europe. The latter species is adapted to more continental climate conditions and shows a later flowering time (August–September) than the widespread S. ovatus (July–August) that grows in more oceanic climates. We have surveyed(More)
