Distribution and ecology of cytotypes of the Aster amellus aggregates in the Czech Republic.

BACKGROUND AND AIMS Polyploidy is viewed as an important mechanism of sympatric speciation, but only a few studies have documented patterns of distribution and ecology of different cytotypes in their contact zone. Aster amellus agg. (Asteraceae) is one of the species with documented multiple ploidy levels. The aim of this study was to determine spatial distribution and ecology of two cytotypes,...

Diploid and polyploid cytotype distribution in Melampodium cinereum and M. leucanthum (Asteraceae, Heliantheae).

Previous chromosomal studies within Melampodium (Asteraceae, Heliantheae) of Mexico and Central America have documented chromosome numbers n = 9, 10, 11, 12, 18, 20, 23, 25 ± 1, 27, 30, and 33. Some species also have been shown to exhibit infra- and interpopulational polyploidy. The presence of cytotype mixtures is especially pronounced in the white-rayed complex, which occurs in the southweste...

Mycorrhizal Symbiosis and Local Adaptation in Aster amellus: A Field Transplant Experiment

Many plant populations have adapted to local soil conditions. However, the role of arbuscular mycorrhizal fungi is often overlooked in this context. Only a few studies have used reciprocal transplant experiments to study the relationships between soil conditions, mycorrhizal colonisation and plant growth. Furthermore, most of the studies were conducted under controlled greenhouse conditions. Ho...

Aster shennongjiaensis (Asteraceae), a new species from central China

A new species of Aster (Asteraceae) from China, Aster shennongjiaensis W. P. Li et Z. G. Zhang, is described and its morphology and karyotype illustrated. Aster shennongjiaensis is apparently endangered, presently known only from one small population in bamboo forests of Shennongjia Reserve in central China. On a morphological basis, the closest species to A. shennongjiaensis is A. lasiocladus ...

Cytological features of the Aster ageratoides complex (Asteraceae) in Taiwan

Chromosome cytology was examined in two species of the Aster ageratoides complex, A. ageratoides Turcz. (= A. leiophyllus Franch. et Sav.) and A. lasioclada Hayata, in Taiwan. Of the 70 individuals of A. ageratoides sampled, one was found to be diploid (2n = 18) and the rest tetraploid (2n = 36, 37). The occurrence of the diploid A. ageratoides in Taiwan appears to be ancient. Eighteen individu...
