dc.description.abstract | Two species of the genus Petasites, P. kablikianus (occurs upstream) and P. hybridus
(occurs downstream), form characteristic tall herb communities in two altitudinal
zones of Carpathian streams and rivers. They are described as “altitudinal vicariants”
due to their substitution with decreasing elevation on similar habitats along mountain
streams. This would indicate that the phenomenon is conditioned by climatic
factors. In this study, we investigated the factors that determine this substitution on
streambanks, and whether P. hybridus competes with P. kablikianus and limits its
spread from mountains to foothills. We analyzed 72 plant patches from the Western
and Eastern Carpathians in terms of flora composition, and geomorphological
features of the habitat. The content of organic matter, available Mg, P, K, C, total N,
and pH were also analyzed for a representative group of patches. Phytocoenoses were
analyzed based on the presence of one of the analyzed species or on the quantitative
proportions, in the case of a co-occurrence. We found statistically significant
differences in the soil structure (skeleton percentage), content of Mg, N, and C, and
the values of the C:N ratio. These results revealed that P. kablikianus prefers skeletal
soils with a lower clay content, that is rich in Mg, N, C, and organic matter. Petasites
hybridus prefers finer soils, which are richer in pulverized and clay fractions, in a
zone of decrease of soil richness and where a thick layer of humus is typical for its
phytocoenoses. We found that the spread of P. kablikianus into lower locations is
not limited by competition with P. hybridus, but rather by the quality and structure
of the habitat. Therefore, both species should be treated as ecological rather than
altitudinal vicariants. | pl_PL |
