摘要

Urban ecosystems are undergoing changes due to biological invasions and climate change. In this study, we compare shifts in the species composition of ruderal plant communities in Bratislava, with a particular focus on honey-bearing plant species in four phytosociological classes of ruderal herbaceous vegetation. Our comparisons indicate that while plant species richness has remained stable, the presence of invasive species has increased, especially in the Artemisietea vulgaris, Galio-Urticetea, and Stellarietea mediae classes. Native species such as Carduus crispus, Centaurea scabiosa, and Epilobium dodonaei have declined, while invasive species such as Solidago canadensis, Solidago gigantea, Reynoutria × bohemica, and Symphyotrichum lanceolatum have expanded their range and increased in cover. Regardless of these changes, the mean melliferous potential of weedy plant communities has remained almost unchanged. Even the spread of melliferous invasive species has contributed to a slight increase in nectar-producing and pollen-producing potential, especially in the Galio-Urticetea class. The potential has also increased in the Stellarietea mediae class due to the more frequent occurrence of native melliferous species. An important finding is that the abundance of honey-bearing species flowering in late summer and autumn, when few species of trees and agricultural plants flower in and around the city, has remained unchanged despite climate change. Our findings highlight the importance of continuous monitoring and adaptive urban planning to sustain pollinator resources amidst changing species compositions, particularly as invasive species continue to shape urban plant communities.
