Floristic data from Miskolc and the Bükk Mountains (N Hungary)
267-274Views:96In the paper new floristic data originated form field works between 2009 and 2014 in the Bükk Mountains and in the city of Miskolc, Hungary are reported. Data presented here are mainly from the eastern part of the mountain range, near Miskolc, but there are also some data from the central and northern part of the mountains. The most interesting result is the discovery of a new stand of Epipactis tallosii in the inhabited area of Miskolc-Hejőcsaba, but in the inhabited area of Miskolc Cephalanthera damasonium, Neottia nidus-avis and Allium scorodoprasum was also found. New localities of Callitriche c.f. palustris, Alisma lanceolatum and Berula erecta are provided, which species have not been found in the Bükk recently, while Lactuca perennis, Crepis biennis and Lycopus europaeus was not known in the township of Miskolc so far. New localities of Iris pseudacorus, Iris sibirica, Clematis integrifolia, Carex acutiformis, Thalictrum lucidum, Pseudolysimachion longifolium etc. were found near MiskolcKomlóstető, Epipactis microphylla, Carex acuta, Eqiusetum telmateia, Listera ovata etc. were found near Miskolctapolca, and Epipactis tallosii, Juncus tenuis, Carduus nutans, Berula erecta, Scutellaria galericulata, Myosotis scorpioides and Ranunculus sceleratus were found in the vicinity of Miskolc-Görömböly. It can be concluded that the flora of the surroundings of Miskolc (i.e. Miskolc-Komlóstető, Miskolctapolca and Miskolc-Görömböly) are not yet known sufficiently.

Temperature and soil moisture regimes of the forested and non-forested dolines of the Bükk Mountains based on ecological indicator values
331-338Views:98In 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.

New occurrence of Myricaria germanica in a secondary habitat (NE Hungary)
118–122Views:22542In this paper, we report a new occurrence of Myricaria germanica (L.) Desf in a secondary habitat from the north-eastern part of Hungary, from the edge of the Bükk Mountains, in a slag dump in Miskolc. The plant is established on a steep wall formed during the extraction of slag. Due to the erosion of the wall, occasionally a few plants fall off. The age of the dead specimens is between 5 and 13 years, based on their growth rings. The population of about 50 individuals is the largest (but perhaps the only) living population of the species in Hungary. Other rare and protected species (Epilobium dodonaei Vill., Dysphania botrys (L.) Mosyakin & Clemants, Dryopteris carthusiana (Vill.) H.P. Fuchs, Polystichum aculeatum (L.) Roth ex Mert.) have also been found in the slag heap area.

Ceratocephala testiculata (Crantz) Roth and further data to the flora of the foothills of Bükk Mts.('Bükkalja', NE Hungary)
81-142Views:223This paper reports new floristic data of 367 taxa (365 species and two hybrids) from the foothill region of Bükk Mts. ('Bükkalja', NE-Hungary) based on 5470 field collected data records. The data was collected between 1997–2014 and supplemented with herbaria (altogether 344 herbaria sheets). Data evaluation was based on the comprehensive Bükk Flora of András Vojtkó and further papers. Altogether 45 species were registered as previously unreported from the area, whereas three species had old data (Acer negundo, Elaeagnus angustifolia, Xanthium strumarium). Out of the newly registered species six native species inhabits natural habitats (Carex flacca, Ceratocephala testiculata, Glycerrhiza echinata, Gypsophila paniculata, Kochia laniflora, Marrubium vulgare), whereas five species represents the weed flora (Anthemis ruthenica, Chenopodium ficifolium, Eragrostis pilosa, Senecio vernalis, Xanthium strumarium). The majority of the newly observed species are adventives. Five species were also regarded as recent introduction regionally, although they are native in the country (mostly lowland species: Crypsis alopecuroides, Limonium gmelini subsp. hungaricum, Salsola kali, Scirpoides holoschoenus, Trifolium angulatum). Typical threats observed are landscape and habitat degradation by invasive alien species out of which 11 are newly added. Mass occurrences were detected for the following invasive alien species: Bidens frondosa, Impatiens glandulifera, Phytolacca esculenta, Xanthium italicum. 43 species are also registered, which did not have recently published data from the area. These species include more native elements representing different habitat preferences (dry grasslands, wet meadows, forest and weeds). In case of 65 species the unravelled new occurrences increased significantly, thus contributed to the clarification of their distribution pattern. It was found that the floristic data accumulated on a decade-scale are not sufficient for the analysis of floristic trends, but could serve as a good basis for surveying floristic gradients between the mountainous and lowland areas.

New montane species in the Hungarian bryophyte flora
16-26Views:652During a bryofloristical investigation in the vicinity of Ómassa (Miskolc) in the Bükk Mountains (NE Hungary), three montane-boreal bryophyte species new to the Hungarian bryoflora were collected. Encalypta spathulata Müll.Hal. was found on the ledges of limestone cliffs of Vörös-kő Hill as well as on the rocky debris among roots of a fallen tree lying under the cliffs. Hydrogonium croceum (Brid.) Jan Kučera and Orthothecium rufescens (Dicks. ex Brid.) Schimp. were found in the crevices of dolomite cliffs on the north-facing steep slope of Jávor Hill. While the latter two species are widespread in European Mountains, E. spathulata is considered to be a rare species, and is assessed as ‘Vulnerable’ in the IUCN red list.
