Data to the flora and vegetation of Hungary III.
197-206Views:158We 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.

Data to the flora and vegetation of Hungary I.
89-104Views:87The 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.

Temperature and soil moisture regimes of the forested and non-forested dolines of the Bükk Mountains based on ecological indicator values
331-338Views:114In the study we aimed to investigate whether there are differences in the ecological conditions of the forested and non-forested dolines of the Bükk Mountains (northern Hungary). Transects for sampling the herb layer were established across three forested and three non-forested dolines in a north to south direction, traversing the deepest point of the dolines. Presence-absence data of each vascular herb and tree sapling were recorded in the plots. Borhidi’s indicator values for temperature (TB) and soil moisture (WB) were used to compare the ecological conditions along the slopes. Our results showed that there were remarkable differences between the temperature and moisture regimes of the forested and non-forested dolines. Both the temperature and moisture gradients were more pronounced along the slopes of the non-forested dolines than along the forested ones. These are due to the fact that forest cover together with the features of the regional climate of the area has a considerable mitigating effect both on the air temperature and soil moisture regimes of dolines.

Data to the flora and vegetation of Hungary II.
104–113Views:174We 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).
