摘要

Ponds represent ecologically valuable habitats that often support greater biodiversity compared to other types of aquatic ecosystems. During the summer and autumn of 2022 and 2023, comprehensive phytosociological research was conducted to establish the diversity of the phytocoenoses in pond complexes along the South Morava River (Serbia). A dataset comprising 638 relevés and 109 species was analyzed using UPGMA classification analysis to determine plant communities, while Detrended Correspondence Analysis (DCA) was employed to characterize the ecological gradients underlying vegetation patterns. The most frequently recorded stands belonged to the associations Typhetum latifoliae, Typhetum domingensis, and Potamo pectinati-Myriophylletum spicati, whereas Cyperetum flavescentis, Potametum lucentis, and Potamo crispi-Ranunculetum trichophylli were among the least common. A total of ten invasive species were recorded, of which Elodea canadensis, E. nuttallii, Paspalum distichum, and Amorpha fruticosa formed monodominant stands. Six law-protected plant species were documented (Potamogeton nodosus, Cyperus glomeratus, Trapa natans, Utricularia vulgaris, Epilobium hirsutum, Betula pendula). DCA revealed moisture, temperature, and light as the primary environmental gradients shaping vegetation composition. Communities belonging to the classes Lemnetea and Potamogetonetea are associated with higher moisture conditions and elevated pH conditions. Most communities of the class Phragmito-Magnocaricetea occur in warmer, well-lit environments with reduced pH. Isoëto-Nanojuncetea communities occupy drier, lower pH sites with higher light availability. Effective conservation of pond complexes in the South Morava River valley requires long-term, standardized vegetation monitoring, protection of temporary ponds, early control of invasive species, and the preservation of heterogeneous pond habitats to sustain high biodiversity and support future ecological studies.
