Distribution and some features of biology and ecology of alien species <i>Dipsacus fullonum</i> L. (<i>Dipsacaceae</i>) in the Bryansk Region
The article discusses the distribution and some features of the biology and ecology of the alien species Dipsacus fullonum L. ( Dipsacaceae ) within the secondary area in the Bryansk Region. The new localities of the species in the region are given. The plant communities in which D. fullonum is the dominant are described. The results of an experiment to determine the germination of seeds in laboratory conditions on various substrates are considered. The materials on the study of various age states are presented. Within the secondary area in the Bryansk Region, D. fullonum exhibits the properties of an ephemerophyte-colonophyte and spreads only through disturbed habitats. The species has a weak competitiveness, as a result of which, in the places of observation during the succession, it is likely to be replaced from the originally occupied territories by perennials, in particular, Calamagrostis epigeios and Solidago canadensis . There is still insufficient data to predict the distribution and threats from D. fullonum in the region, however, it can be argued that this species does not exhibit the properties of a transformer.
