AttilaTétel Korlátozottan hozzáférhető Active dispersion, habitat requirements and human biting behaviour of the invasive mosquito Aedes japonicus japonicus (Theobald, 1901) in HungarySáringer-Kenyeres, Marcell; Bauer, Norbert; Kenyeres, Zoltán; PhD hallgatóAedes japonicus japonicus is endemic in a number of countries in eastern Asia but has been accidently introduced into many regions of the world including Europe. It was first detected in Hungary in 2012. In 2017, robust populations of the species were found at Lake Balaton, one of the most important tourist destinations in Central Europe. Based on the experience gathered in the above localities, habitat requirements, dispersion abilities and human biting behaviour of the species were studied in western Hungary during 2017 and 2018. Our results show that (a) a few years after its detection at the Slovenian-Hungarian border, Ae. j. japonicus is widespread in at least two-thirds of the western half of Hungary; (b) the species spreads quickly in ecological corridors formed by mosaics of rural areas, detached houses, gardens and small forest patches; (c) Ae. j. japonicus occupies artificial containers; (d) expansion of the species into new areas is slowed by extensive closed forest patches.Tétel Szabadon hozzáférhető Adatok a Sorbus bakonyensis elterjedéséhez és megőrzéséhez(2022-10-03) Bauer, NorbertSorbus bakonyensis (Jáv.) Jáv. (syn. S. majeri Barabits) is an apomictic species with a very narrow distribution range in the Bakony Mts (Hungary). Its previous occurrence data were published only from Kopasz Mt. (~Kápolna Hill, Csordás valley) above the village Márkó. It was possible to slightly expand the known area of the species to the East and to the West (Kis-Bükk Mt) of Kopasz Mt. with a detailed mapping. Due to the number of known individuals (six mature trees and a variable number of seedlings) and its small distribution range (~2 km 2 ) the species is critically endangered. Regarding its small population, the high number of big game (wild boar, red deer) and the more and more frequent drought periods are significant risk factors. In situ preservation of the species is still a realistic goal, but ex situ propagation in tree nurseries and reintroduction to the suitable habitats of the mapped area (clearings, forest edges) are also justified.Tétel Szabadon hozzáférhető Apró közlemények(2015-07-01) Bauer, Norbert; Balogh, Lajos; Bezeczky, Árpád; Nagy, József; Deák, Balázs; Kiss, Orsolya; Valkó, Orsolya; Schmidt, Dávid; Török, Péter; Szűcs, Péter; Kovács, Dániel; Lengyel, Attila; Máté, András; Somlyay, Lajos1.

From a phytogeographical point of view, the most important is Astragalus vesicarius , whose small population in the Vértes fits very well into the native distribution pattern of the species in Hungary. Another important steppe plant is Stipa dasyphylla , which is found in two locations in the Vértes Mts. Besides other taxa of conservation interest ( Orobanche teucrii , Phelipanche purpurea , Rosa hungarica ), some under-recorded species ( Cerastium tenoreanum , Stellaria pallida ), and some spreading weeds ( Elymus elongatus , Euphorbia lathyris ) enrich our knowledge of the flora of the area.Tétel Szabadon hozzáférhető Basic characteristics of microhabitats of snake-eyed skink (Ablepharus kitaibelii) in Western Hungary(2021) Kenyeres, Zoltán; Bauer, Norbert; Cservenka, Judit; Szabó, Szilárd; Tóth, SándorTétel Szabadon hozzáférhető A Crepis mollis (Jacq.) Asch. subsp. hieracioides (Waldst. & Kit.) Domin újrafelfedezése Magyarországon(2015-01-01) Bauer, Norbert; Somlyay, LajosCrepis hieracioides (= C. mollis subsp. hieracioides ) was described from the Bakony Mts. (Western Hungary) by Pál Kitaibel more than 200 years ago. His record has been the single one of this taxon from the territory of present-day Hungary thus far. In the second half of the 20 th century this taxon was either reported as ‘extinct’ or was plainly ignored in the Hungarian literature. This paper reports about the recent rediscovery of C. mollis subsp. hieracioides in the Bakony Mts., specifically in the ‘Bakonyalja’ region (Devecser: Széki-erdő). The habitat is characterised, and the regional phytogeographical significance of this taxon is emphasised.Tétel Szabadon hozzáférhető A csókalábú útifű (Plantago coronopus) folytatódó térhódítása Magyarországon(2020-04-16) Schmidt, Dávid; Bauer, Norbert; Fekete, Réka; Haszonits, Győző; Süveges, Kristóf; Molnár V., AttilaIn the course of our research of Hungarian transport routes, we observed an intensive spread of the Atlantic-Mediterranean Plantago coronopus L., a recently established species in Hungary. Between 2017 and 2019, it was detected in 47 flora mapping quadrats, which increased the total number of occurrences to 81 since 2013. Besides motorways, the main Hungarian transport routes were involved as well. 26 occurrences have been recorded along the roads 4/E60, E573, 8/E66, 86/E65 and 87, which are severely affected by international traffic. However, on routes avoiding international transit traffic, the species’ occurrences are still rare. In some cases, the predominant direction of traffic appeared to influence the formation of new stands. It is very likely that the first individuals that appeared along the section of the M86/E65 motorway between Szombathely and Hegyfalu in 2019, arrived primarily by northbound traffic, rather than along the road 86, which runs parallel to it only a few hundred meters away. Likewise, it seems certain that the spread of the species along the roads M1/E60, E75 (Mocsa, Tata, Páty) and M7/E71 (Fonyód, Balatonlelle, Kajászó) as well as the road 8/E66 (Bakonygyepes, Veszprém) is due to reproduction of older extensive local populations. At several localities along the outer bend of roundabouts or near the exits of motorways, a dispersal role of intense winter road salting was also observed. The largest populations were located mostly along ditches, next to the (often bare) lane of roadbeds that are heavily affected by mechanical and osmotic stress. The majority of stands were found within a 3 meters wide belt along the asphalt strip (5 meters was measured in the lawn of a cemetery once). Since the species is present continuously at several localities since 2013, it is considered as naturalised in Hungary, and its further spread can be confidently predicted. The current status of the species in Hungary is naturalised (non-trans¬former) neophyte.Tétel Szabadon hozzáférhető Distribution and seed production of the rare, dry grassland specialist Sternbergia colchiciflora (Amaryllidaceae) in Pannonian cemeteries(2018) Molnár, V. Attila; Mészáros, András; Csathó, András István; Balogh, Gábor; Takács, Attila; Löki, Viktor; Lovas-Kiss, Ádám; Tökölyi, Jácint; Somlyay, Lajos; Bauer, NorbertTétel Szabadon hozzáférhető Felföldy Lajos (1920–2016)(2017-01-01) Molnár V., Attila; Csányi, Béla; Vidéki, Róbert; Bauer, Norbert; Dolánszky, Ferenc; Papp, Viktor Gábor; Nótári, Krisztina; Buczkó, Krisztina; Gulyás, Pál; Virók, ViktorLajos Felföldy (1920–2016) was one of the most versatile and open-minded Hungarian biologists. He began his scientific career as a student of Prof. Rezső Soó. Between 1938 and 1946 he participated in geobotanical studies in University of Debrecen and Kolozsvár (Cluj-Napoca, Romania). He contributed with important achievements to the development of several biological disciplines. His pioneering study on the effects of air pollution on epiphytic lichens (1942) was among the firsts in the world. He described Hemitherophyte life-form as a discrete unit within Raunkiaer's plant life-form system (1942). He was a pioneer in the cytological (caryological) study of wild vascular plant species in Hungary (1947–1949). His results regarding to primary production of freshwater algae and algal culture (1958–1960) were in leading edge. In 1972 he founded and until 1990 edited the Hungarian series entitled ‘Vízűgyi Hidrobiológia’. Books of this series aimed to publish identification keys of freshwater taxa. These books were proved to be decisive and useful tools for Hungarian hydrobiologists in biological classification of brooks, streams, rivers and different types of stagnant waters. Between 1934 and 2009 he collected more than ten thousand herbarium sheets. After his retirement, he dealt with the revision of the herbarium material of Department of Botany in Hungarian Natural History Museum and Botanical Garden of Eötvös University (Budapest). He participated in the preparation of the New Hungarian Herbal. His scientific work was characterised by deep humility for nature, which was founded on strong theoretical and practical background.Tétel Szabadon hozzáférhető Kiegészítések az Orobanche reticulata biológiájához és hazai elterjedéséhez(2021-04-26) Bauer, NorbertSome new Hungarian occurrences of Orobanche reticulata Wallr. are discussed in this paper. On the Bér-hegy hill (Eastern Bakony Mts) the species was observed on a so far unknown host plant ( Carduus hamulosus ). Although the species usually flowers from May to July in Hungary, the observed individual was in full bloom in October, probably due to the extremely rainy year (2010). Another population of the species, found at Magyaralmás settlement in the foreground of the Vértes Hills, deserves attention because of its size. In early summer of 2020, individuals of O. reticulata appeared in a great quantity (several hundred ones) on a fallow land that was developed from a natural dry grassland having been ploughed in the previous year. In this case the local host plants were Carduus nutans subsp. leiophyllus and Carduus acanthoides . Some further records of the species from the Transdanubian Mts and the regions of Külső-Somogy and Mezőföld present new data in the Hungarian flora mapping program.Tétel Szabadon hozzáférhető Leucojum vernum a Súri-Bakonyalján és a faj Bakony-vidéki elterjedésének áttekintése(2020-11-12) Bauer, NorbertIn Hungary Leucojum vernum is considered a plant species of montane character, distributed predominantly in Transdanubia. Apart from some isolated localities (Zalaszántó Basin Mts, Tapolca Basin), the occurrences of the species are mainly confined to the region “Magas Bakony” and its periphery within the Hungarian Middle Mts. In the spring of 2020 a large population was discovered by the author in the region “Súri-Bakonyalja”, which significantly expands the known local distribution range of the species. The new population, together with other phytogeographically significant species (e.g. Anemone nemorosa, Corydalis intermedia, Veratrum album), was found in a poorly explored valley system (Kisbér village: Báró-erdő). Based on all literature and herbarium records, the local distribution range of L. vernum is surveyed.Tétel Szabadon hozzáférhető Sorbus udvardyana Somlyay & Sennikov a Balaton-felvidék keleti dolomitterületén(2015-01-01) Bauer, NorbertRelated to distribution of S. aria s.l. × S. torminalis hybrid taxa in the eastern part of the Balaton Uplands just data of „ S. balatonica ” is in the literature based on collection of Ádám Boros (Kárpáti 1960). In the summer of 2014 the author found and mapped a few (sub)populations of S. aria s.l. × S. torminalis at Lovas (Királykúti-völgy, Atya-hegy, CEU: 8973.4) and Felsőörs (Malom-völgy, Kopasz-tető, CEU: 8973.4) villages. Based on leaf-morphological traits the specimens were identified as S. udvardyana .Tétel Szabadon hozzáférhető A Spiraea media Fr. Schm. Balaton-felvidéki előfordulásáról(2018-07-01) Varga, Szabolcs; Sinigla, Mónika; Bauer, NorbertThe presence of Spiraea media on the Balaton Uplands has high plant geographical importance, but the found location has not been known before its recent rediscovery. The Spiraea media was discovered on the Kopasz Hill (Felsőörs) growing in a closed Quercus cerris oak forest (~ Fraxino orni-Quercetum cerridis ); which is a rather atypical habitat of the species. The appearance of blooming specimens and the rediscovery of the species is probably due to the cut of the neighbouring forest, which has resulted extra irradiation in the area. The 19 th century military maps of the landscape show that the former vegetation of the area was characterised by the mosaics of rocky grassland–scrub–forest or rocky scrub rich patches being suitable for the species.Tétel Szabadon hozzáférhető The distribution of Ranunculus psilostachys Griseb. in Hungary and the question of its indigenousness(2022) Erdős, László; Kevey, Balázs; Török, Péter; Tölgyesi, Csaba; Bauer, NorbertTétel Szabadon hozzáférhető A Torilis nodosa új behurcolásai és terjedése Magyarországon(2023-02-07) Kun, András; Exner, Tamás; Bauer, NorbertTorilis nodosa (L.) Gaertn. is an Atlantic-Mediterranean weed species. Its old data are known from Budapest, but these may have been occasional occurrences, the species has not been confirmed in Hungary for more than a hundred years. In the last few years, we have found six new occurrences of the species in Hungary, one population in Budapest, and another five in some settlements on the northern shore of Lake Balaton. The species was observed in ruderal or intensely mowed urban habitats, in all cases. Intensive tourism has a role in its introduction for sure, but for the survival of self-sustaining stands and in its already perceptible regional spreading, the climate change trends, the increasingly mild winters, and the decreasing number of frost days could also be important. New data from Hungary are well connected to its other Central European observations.Tétel Szabadon hozzáférhető A Velencei-hegység növényföldrajzi és florisztikai kutatásának eredményei(2019-07-01) Bauer, NorbertA recent floristic mapping of the Velence Hills has clarified the local distribution of many plant species. This study presents records of 219 phytogeographically significant or sporadic/rare taxa (216 species/subspecies and 3 natural hybrids). The local distribution of some species representing typical regional distribution patterns ( Alyssum turkestanicum, Artemisia austriaca, Bupleurum pachnospermum, Doronicum hungaricum, Hypericum elegans, Lathyrus sphaericus, Minuartia viscosa, Ornithogalum comosum, Scabiosa canescens, Sedum caespitosum, Sternbergia colchiciflora, Vinca herbacea ) are shown on maps. More than fifty taxa previously unknown from the area were recorded during the floristic mapping, including phytogeographically significant ones, such as Bassia laniflora, Brassica elongata, Bupleurum praealtum, Centunculus minimus, Hypericum elegans, Orlaya grandiflora, Phleum bertolonii, Silene dichotoma, Stipa tirsa, Tordylium maximum, Trifolium diffusum, T. ochroleucon and Valeriana dioica . In terms of phytogeography, the Velence Hills can primarily be characterised by the co-existence of continental and sub-Mediterranean elements as well as species of acidophil and strongly basic habitats.
