Tétel Szabadon hozzáférhető A növényi magtömeg-variabilitás ökológiai háttere és jelentősége(2014-07-01) Sonkoly, Judit; Molnár V., Attila; Török, PéterThere is an almost twelve order of magnitude difference in the seed weight of recent plant species. Studying the causes, patterns and consequences of this high variability is a crucial issue in plant ecology. In this paper we summarise the main conclusions of the studies in this topic to get a broad and general view of the possible explanations of high variability in seed weights and its consequences on dispersal, seed predation, seed bank formation, germination, establishment and plant growth, and on the structure and function of plant communities. Because of the extremely high number of papers published in this topic, we aimed at to concentrate on papers published in highranked international journals in the last few decades, having a special focus on publications from the Carpathian Basin. It was found that growth form, body size, genom size, latitude and light availability are responsible for the detected high variability in the seed weights of species. Infra-individual variability is mostly caused by the effects of the position on the maternal plant and the seed size – seed number trade-off. The effect of dispersal by wind or by seed predators on the variability of seed weights and its ecological consequences are the most studied. Predicting persistence on the basis of seed size and seed shape also has been a popular research topic lately. Studying the effects of seed weight variability on the structure of plant communities is also becoming more and more important, but no general conclusions could be drawn yet.Tétel Szabadon hozzáférhető Adatok Miskolc és a Bükk hegység flórájának ismeretéhez(2014-07-01) Sonkoly, JuditIn 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.Tétel Szabadon hozzáférhető A bükki erdős és gyepes töbrök növényzetének hőmérsékleti és talajnedvességi indikációja(2014-07-01) Bátori, Zoltán; E. Vojtkó, Anna; Erdős, László; Vojtkó, AndrásIn 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.Tétel Szabadon hozzáférhető Florisztikai adatok a Tiszántúl északi pereméről(2014-07-01) Takács, Attila; Zákány, Albert; Gulyás, Gergely; Koscsó, János; Sramkó, GáborThis paper reports new floristic data of 161 taxa. Most of these data were collected between 2011–2013, and are coming from the northern edge of the floristic region 'Crisicum', the NE part of the Great Hungarian Plain, which is a little-known area from a floristic point of view. 43 CEU quarterquadrates and territory of 35 settlements are represented by the dataset. The paper reports occurrence localities for legally protected (e.g. Ophioglossum vulgatum, Stellaria palustris, Ranunculus polyphyllus, Thlaspi jankae, Lathyrus palustris, Elatine spp., Lycopsis arvensis, Lindernia procumbens, Cirsium brachycephalum, Cyperus pannonicus), strictly protected (Armoracia macrocarpa, Vicia biennis) and some little-known (e.g. Cardamine parviflora, Reseda luteola, Melilorus dentatus, Veronica catenata) taxa. Numerous data of alien species (e.g. Lepidium densiflorum, Euphorbia maculata, Sicyos angulatus, Erechtites hieracifolia, Elodea nuttallii, Elymus elongatus, Eleusine indica, Sorghum halepense, Eriochloa villosa) are also published. The most important data are documented by voucher specimens deposited in herbarium of Debrecen University (DE).Tétel Szabadon hozzáférhető Apró közlemények(2014-07-01) Pintér, Balázs; Barina, Zoltán; Szűcs, Péter; Börcsök, Zoltán; Kámán, Orsolya; Vojtkó, András; Juhász, Tamás; E.

The main aim of this initiation is the promotion and familiarization of Hungarian flora, applying a public awareness campaign about the beauty, importance and ecological value of our spectacular wild plants. The ’Wildflower of the Year’ is selected by voting on internet (www.evvadviraga.hu). Starting from this volume the journal Kitaibelia publishes a monograph about the wildflower of the previous year.Tétel Szabadon hozzáférhető Tétel Szabadon hozzáférhető Neofiton Campylopus introflexus (Hedw.) Brid. elterjedése Magyarországon(2014-07-01) Szűcs, Péter; Csiky, János; Papp, BeátaBased on field work data collected in 2013–2014, the authors generated a map of the current distribution of Campylopus introflexus for Hungary. Besides the coordinates and geographic name of the localities, an estimated size of the population, the type of habitat and substrate, the co-occurring moss species and affected vegetation types were also recorded. Altogether, 18 stands were found in 8 geographical regions of Hungary, in some cases Campylopus introflexus was found to be a new species record for the moss flora of the respective region (e.g. Dunántúli-dombság, Nyugatmagyarországi peremvidék). In addition to the pine plantations from where it was detected formerly, the mixed deciduous-coniferous forests, the acidophilous oak woodlands and man-made habitats were found to be also proper habitats for this moss taxon. Earlier data mainly originated from pine deadwood, the recently discovered stands were found on acidic soil surfaces. The most important cooccurring moss species were the followings: Hypnum cupressiforme, Polytrichum piliferum, P. formosum, Pohlia nutans and Ceratodon purpureus. Campylopus introflexus had prominently high coverage in the acidophilous oak forests of the Mecsek Mts, where it occurs on acidic sandstone covered with a thin debris of the bedrock. This neophyte moss is widely distributed in Hungary, and has stable populations. Further expansion is expected in the subatlantic and submountain regions of the country, and in regions characterised by acidic soils and pine plantations.Tétel Szabadon hozzáférhető Florisztikai adatok a Cserhát felhagyott szőlőiből(2014-07-01) Malatinszky, Ákos; Mravcsik, Zoltán; Dedák, DalmaThe results of floristic researches in abandoned vineyards of Cserhát Hills (Northeastern Hungary) between 2007 and 2014 are presented along with an account of relevant floristic literature and specimens of the Herbarium Carpato–Pannonicum Collection of the Hungarian Natural History Museum. Data of protected species and locally or generally rare ones are presented. Occurrences of Equisetum × moorei, Hesperis sylvestris, Gentiana cruciata, Scabiosa canescens, Campanula macrostachya, Carlina acaulis, Centaurea indurata, C. stenolepis, Epipactis atrorubens and Orchis ustulata subsp. aestivalis are especially significant. Some new localities of the following species are also emphasized: Pulsatilla grandis, Sorbus domestica, Centaurea scabiosa subsp. sadleriana, Orchis militaris, O. × hybrida, Ranunculus arvensis, Rapistrum perenne, Chamaecytisus virescens, Ch. austriacus, Hippocrepis comosa, Euphorbia salicifolia, Thymelaea passerina, Senecio erucifolius.Tétel Szabadon hozzáférhető Újabb adat a magyar adventív flóra ismeretéhez: az Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Willd.) Gams 1925 Magyarországon(2014-07-01) Korda, MártonAcer opalus Miller 1768 because of its complex taxonomic status can be interpreted as a collective species which contains several species and subspecies depending on different interpretations. An important adventive occurrence from this collective species was found in a forest that belongs to the Tétényi plateau (Budapest, 11th district) in July of 2009. It is proved to be Acer opalus Mill. subsp. obtusatum (Waldst. et Kit. ex Wild.) Gams. The natural range of the subspecies covers the eastern side of the central Mediterranean Sea region and western Balkan Peninsula. It is a submediterranean-mediterranean, thermophile, shade-tolerant taxon but often appears together lightdemanding species too. In its native range it occurs in beech, pine, sessile oak forests and in different types of dry oak forests as admixed tree species. The subspecies was found in a turkey oak – sessile oak community in Hungary. Several old, seed growing individuals live on the spot which have had continuous seed production. Therefore from the old trees to the young seedlings different age categories are represented.Tétel Szabadon hozzáférhető Palkó Sándor (1959–2002) emlékezete(2014-07-01) Bódis, Judit; Farkas, Sándor; Molnár, László; Molnár V., Attila; Óvári, Miklós; Vidéki, RóbertSándor Palkó (1959–2002) was the first nature conservation surveyor in Zala county at the Balaton-uplands National Park. While he was nation-wide recognized ornithologist, he extended our knowledge with many floristic data too, but we remember him mostly for his imaginative activity in nature conservation. He sent on his experience dozens of young conservationists and stood them on their own ways. His dedication carried with him all those who had predisposition. The Research and Ringing Camp of Fenékpuszta established by him has become one of the most important camps of the country for avian migration research and nature conservation practices.Tétel Szabadon hozzáférhető Észrevétlen özönfaj a magyar flórában, az örmény szeder (Rubus armeniacus Focke)(2014-07-01) Király, Gergely; Trávnícek, Bohumil; Žíla, VojtěchThe authors report on the occurrence, distribution and invasion potential of Rubus armeniacus, a bramble species of Caucasian origin, in Hungary. The first verified records of the species are from the 1990s. It has established strong populations in ruderal habitats mainly around Budapest and some other cities, whereas its competiveness is rather weak in closed non-lowland forests rich in native bramble species. In terms of conservation, it constitutes a real threat to the vegetation of Pannonian sandy habitats. The results of this study also emphasize the importance of recognising "nonnative cryptic species" for ecology and conservation biology.Tétel Szabadon hozzáférhető Védett növényfajok mikroszkopikus gombái az Őrségi Nemzeti Parkban és környékén(2014-07-01) Jandrasits, László; Fischl, GézaThe paper deals with the study of microscopic fungi occurring on protected plant species of the National Park of Őrség and the surroundings. The survey includes both field observations and laboratory tests. The aim of the study was to identify the microscopic pathogen fungi living on protected plant species. Also spatial and temporal distribution, infection and damage rate of pathogenic fungi infections were determined for some protected plant species. Between 2002 and 2009 mycological research was conducted including 78 protected plant species and near to one hundred fungus species were identified on them. We provided data at the first time of microscopic fungi found on protected plants of Őrség.Tétel Szabadon hozzáférhető Botanikai adatok Tolnából és Baranyából II.(2014-07-01) Tóth, István ZsoltThe present study reports the occurrence data of some rare and legally protected vascular plant species, collected at Tolna county and the northern part of Baranya county during field work between 2012–2013. Among the reported floristic data, the occurrence of Ranunculus lingua, Potentilla rupestris and Malva alcea are new for Tolna county. Further rare species such as Allium angulosum, Althaea hirsuta, Erodium ciconium, Galium rubioides, Glycyrrhiza echinata, Lathyrus palustris, Lathyrus sphaericus, Myagrum perfoliatum, Salvinia natans, Urtica kioviensis and Vicia lutea were also registered on the studied area.Tétel Szabadon hozzáférhető Kiegészítő adatok a Soproni-hegység és előtere flórájához(2014-07-01) Schmidt, Dávid; Nótári, Krisztina; Korda, MártonThe present study reports additional records to the flora of Sopron Hills and Sopron Basin. The records were collected during our field surveys between 2010 and 2014 and contain occurrence data of 19 vascular plant taxa. The genus Orobanche is represented by 5 species. Two taxa are new for the flora of Sopron Hills (Amaranthus blitoides, Orobanche teucrii), others are interesting because of their old or uncertain indication (e.g. Dianthus superbus, Myosotis sparsiflora, Orobanche lutea, Orobanche purpurea).Tétel Szabadon hozzáférhető Adatok Magyarország flórájához I.(2014-07-01) Kovács, DánielThe paper gives new floristic data from several regions of Hungary. Some of them are recent evidences of old data (e.g. Herniaria incana in Pomáz), others are new occurrences of recently expanding alien species (e.g. Eleusine indica, Geranium purpureum, Typha laxmannii), casual species (e.g. Lobularia maritima, Nepeta racemosa) or legally protected taxa (e.g. Agrostemma githago, Ornithogalum brevistylum, Ranunculus illyricus, Sonchus palustris).Tétel Szabadon hozzáférhető A szagtalan rezeda (Reseda inodora Rchb.) előfordulása a Tiszántúlon(2015-01-01) Csathó, András István; Bede, Ádám; Sudnik-Wójcikowska, Barbara; Moysiyenko, Ivan; Dembicz, Iwona; Sallainé Kapocsi, JuditOn 14 August 2012 a small population of Reseda inodora was found in Hegyes-halom kurgan within the administrative boundaries of the town of Mindszent (Csongrád County, CEU: 9487.3). The approximately 50–100-stem-large population of the species lived on the edge of the kurgan, on the sparsely vegetated, weedy fieldmargin. On 19 July 2014 this species has turned up again in this area. In this case it was the biggest amount with some hundred stems and was located on the edge of the mound, which is in the verge of the neighbouring corn field. The Reseda inodora is a new recent protected vascular plant species within the operation area of the Körös–Maros National Park. We propose this species to be included in the regional red list in the category of „CR” (Critically endangered). Other rare weed or pioneer species ( Caucalis platycarpos subsp. muricata and subsp. platycarpos , Erodium ciconium , Lappula squarrosa , Melica transsilvanica , Papaver hybridum ) have already been found in Hegyes-halom kurgan in the last few years. The results show the importance of kurgans not only in the conservation of natural steppe, loess wall vegetation and steppe shrub species, but in the survival of some endangered weed species as well (e.g. some rare archaeophytes).Tétel Szabadon hozzáférhető Sallangvirág (Himantoglossum) fajok virágzás-fenológiája és elterjedési mintázata(2015-01-01) Biró, Éva; Bódis, JuditHybridization is very rare between the species of Himatoglossum genus, despite the fact that it is common in other orchid genera. The reasons for this can be the lack of overlapping distribution areas or the different flowering period of the species. In the paper distribution and flowering data of Himantoglossum species are presented from herbarium sheets or references (sources paper-based or internet). We collected 1001 precisely dated flowering records of 12 species. In case of 6 species ( H. adriaticum, H. caprinum, H. comperianum, H. hircinum, H. jankae, H. robertianum ) we had sufficient records to calculate the average flowering day and blooming length. According to the collected data the distribution of the species are overlapping except for H. formosum, H. galilaeum and H. metlesicsianum. Studying 55 species pairs, insignificant differences in blooming time were only at 21 species pairs, among them only 5 ( H. comperianum - H. caprinum , H. montis-tauri - H. comperianum, H. hircinum - H. adriaticum , H. montis-tauri - H. caprinum és H. jankae - H. calcaratum ) have overlapping distribution area. Data on hybridization could be found only at three species pairs among them. From the results we can conclude that in the case of Himantoglossum genus the rarity of hybridization is mostly due to the phenological isolation.Tétel Szabadon hozzáférhető Apró közlemények(2015-01-01) Szűcs, Péter; Pénzesné Kónya, Erika; Takács, Attila; Löki, Viktor; Csábi, Miklós; Csirmaz, Kálmán; Gregorits, János; Haszonits, Győző; Hernádi, László; Kiticsics, Anikó; Lukács, Róbert; Makádi, Sándor; Marton, József; Molnár V., Attila; Nagy, Timea; Pánczél, Mátyás; Raksányi, Zsolt; Reszler, Gábor; Tóth, Katalin; Babai, Dániel; Kelemen, András; Deák, Balázs; Albert, Ágnes; Valkó, Orsolya; Csathó, András István1.

In many cases kurgans hold the last remnants of dry grasslands in lowland areas, like the Great Hungarian Plain. They also have an essential role in preserving cultural and landscape values. Moreover, they harbour several rare plant and animal species. Our aim was to explore the vegetation of the Mondró-halom kurgan (Hencida, East Hungary). Altogether we found 74 vascular plant species in the loess grassland of the kurgan. Several rare species of the Bihari-sík region, such as Inula germanica , Ranunculus illyricus and Rosa gallica were also detected. The steep slopes of the kurgan with various micro-sites and exposures supported a species-rich vegetation. Instead of its small area it harboured several forest steppic species and several steppic flora elements (Continental, Pontic-Mediterranean, Pontic, Pontic-Pannonic and Turanian).
