Tétel Szabadon hozzáférhető Adatok Magyarország flórájához és vegetációjához I.(2024-04-10) Bátori, Zoltán; Erdős, László; Tölgyesi, Csaba; Aradi, EszterThe present study reports the occurrence data of 54 vascular plant taxa, collected at various localities in Hungary during floristic, vegetation and ecological field surveys between 2000 and 2013. In some cases, phytosociological relevés were prepared to characterize the local coenological properties of the species. Many of these species are included in the „Red list of the vascular flora of Hungary” (e.g. Carthamus lanatus, Sedum caespitosum, Spiranthes spiralis and Trifolium micranthum). Some of them (e.g. Apium repens, Dianthus diutinus, Epipactis bugacensis and Ranunculus psilostachys) are rarities in the whole country. Our findings suggest that conservationists should focus not only on the maintenance of semi-natural habitats but also on the investigation of secondary habitats (e.g. river embankments, temporary pools on arable fields) in order to maintain the total species diversity of the landscape.Tétel Szabadon hozzáférhető Adatok Magyarország flórájához és vegetációjához II.(2017-01-01) Aradi, Eszter; Erdős, László; Cseh, Viktória; Tölgyesi, Csaba; Bátori, ZoltánWe report the occurrence data of 45 vascular plant taxa collected at various localities in Hungary (Duna–Tisza Interfluve, Tiszántúl and South Transdanubia) during floristic, vegetation and ecological field surveys mostly between 2013 and 2016. Many of these plants are included in the ’ Red list of the vascular flora of Hungary ’ (e.g. Astragalus dasyanthus , Erodium ciconium and Lotus angustissimus) . We primarily focused on the occurrence of rare plants (e.g. Apium repens , Epipactis bugacensis and Trifolium strictum ), plants that appeared in unexpected places (e.g. Medicago arabica , Polypodium vulgare and Polystichum setiferum ) or have a phyto-geographic importance (e.g. Piptatherum virescens , Ranunculus psilostachys and Tamus communis ).Tétel Szabadon hozzáférhető Adatok Magyarország flórájához és vegetációjához III.(2018-07-01) Erdős, László; Aradi, Eszter; Bátori, Zoltán; Tölgyesi, CsabaWe report the occurrence data of 44 vascular plant taxa collected at various localities in Hungary (mainly the Danube–Tisza Interfluve and South Transdanubia) during floristic, vegetation and ecological field surveys between 2016 and 2018. Of the species in the present article, 27 are protected or strictly protected. In the paper we focused on plants that are rare regionally (e.g. Botrychium lunaria , Polystichum aculeatum ) or in the whole country (e.g. Ophrys oestrifera , Ranunculus psilostachys ), as well as on plants that occurred in unusual habitats (e.g. Corydalis solida ). We also included new localities of weedy species, some of which (e.g. Opuntia humifusa , Sporobolus cryptandrus ) may present nature conservation threats.Tétel Szabadon hozzáférhető Increasing abundance of an invasive C4 grass is associated with larger community changes away than at home(2022) Hábenczyus, Alida Anna; Tölgyesi, Csaba; Pál, Róbert; Kelemen, András; Aradi, Eszter; Bátori, Zoltán; Sonkoly, Judit; Tóth, Edina; Balogh, Nóra; Török, PéterTétel Szabadon hozzáférhető Invasion of the North American sand dropseed (Sporobolus cryptandrus) - A new pest in Eurasian sand areas?(2021) Török, Péter; Schmidt, Dávid; Bátori, Zoltán; Aradi, Eszter; Kelemen, András; Hábenczyus, Alida Anna; Díaz Cando, Patricia Elizabeth; Tölgyesi, Csaba; Pál, R.
