The phytosociological characteristics of the oak woods on the Szentendre Island were first studied 70 years ago. We conducted a follow-up study to determine the phytosociological relationships of theses woods and assess their possible changes over time. We found that these woods are most similar in their phytosociological characteristics to the closed pedunculate oak forests occurring in the high floodplain in the Szigetköz area (Melico nutantis-Quercetum roboris) along the Danube. Our results also showed a marked increase in the proportion of natural weeds, introduced species and invasive aliens in the studied woods.

A jelen publikáció néhány új Rosa, Crataegus és Pyrus adatot tartalmaz a Čebovce: Kő-hegy (Central Slovakia) területéről. A legfontosabb adatok: Crataegus ovalis Kit. (7. előfordulása Szlovákiában, cf. Baranec, 1986), Rosa bohemica H. Braun (első szlovákiai előfordulása) és a Pyrus × amphigenea Domin ex Dostalek (új magyarországi előfordulás).
