Little is known about the functional significance of heterospory in land plants, nor about how species ensure that mega- and microspores, which have strongly different wind dispersal, are dispersed over similar distances to ensure cross-fertilization

We have investigated genetic variability among 56 individuals of the apogamous Dryopteris affinis complex from 9 populations in Switzerland and Austria using inter-simple sequence repeats. Our sample included 6 diploids, 48 triploids, and 1 tetraploi

Annual alpine species rely on selfing rather than on cross-pollination for successful reproduction. However, insect visits may occasionally cause cross-pollination not only within but also between closely related species. The aim of this study was to

Synthesizing genetic data at population level and vegetation data at community level may give insight into how ecological and evolutionary processes associated with different vegetation influence genetic diversity and differentiation of plant populat

Ecological factors affecting reproduction and dispersal are particularly important in determining genetic structure of plant populations. Polyoicous reproductive system is not rare in bryophytes; however, to date, nothing is known about its functioni

Reproductive ecological traits such as success of fertilization, partitioning of sexes, the relative success of sexual versus asexual reproduction and dispersal distances are likely to considerably influence genetic structure within and among plant p

Homosporous vascular plants are typically depicted as extreme inbreeders, with bisexual gametophytes that produce strictly homozygous sporophytes. This view is promulgated in textbook life cycles despite ample evidence that natural populations of mos
