ABSTRACT

Russian Dock (Rumex confertus), an anthropophyte invading new locations in Poland, settles mainly in ruderal communities and hay-growing meadows. It alters penetrated phytocoenoses which leads to a decrease in biological diversity. Growing in meadows it reduces the fodder quality of hay. Studied populations of Russian Dock are patchily distributed. Ramet clusters covering ca. 1m² are formed due to morphology of the species: its overground parts are joined with underground rhizomes. Spatial distribution of whole genets (clumps) is determined by habitat factors and varies among populations. Plants at earlier development stages inhabit different ecological niches, in a distance from generative genets. Spatial pattern depends also on sex of the individuals, which is clearly associated with different abundance of male and female specimens.

Key words: Russian Dock, Rumex confertus, spatial structure, population.
