The ‘rediscovery’ of the Birdsfoot Fenugreek (Trifolium ornithopodioides (L.) SM.) in the Hortobágy, Hungary
207–212Views:333In 2009, the first author discovered an unknown population of Trifolium ornithopodioides in the Ágota-puszta of Hortobágy plain. In 2016, the second author found an another population in the vicinity of Karcag (Ecse-zug puszta). Up to now there was only one published occurrence of this species from the region. The specimen collected by Szujkó-Lacza Júlia, Kováts Dezső and Fekete Gábor in 1974 was deposited in the herbarium of the Hungarian Natural History Museum (BP), but this incomplete specimen was misidentified, and not Trifolium ornithopodioides. Therefore, this newly discovered site at Ágota-puszta should be regarded as the first trustworthy occurrence of this species at the Hortobágy plain.

Seed dispersal and habitat preference of the endangered Lesser White-fronted Goose (Anser erythropus L.) and larger goose species in the Hortobágy National Park
136-147Views:167Several studies found that waterfowl are important endozoochorous dispersal vectors for plant species. Germination of the seed content of their droppings provides valuable information on their diet and also on their role in seed dispersal. Our aim was to analyse the seed dispersal potential of the critically endangered habitat-specialist Lesser White-fronted Goose (Anser erythropus) in their autumn and spring staging areas in Hortobágy National Park. The study was supported by the LIFE10-NAT/GR/000638 project. We also studied the seed dispersal potential of larger generalist goose species foraging in the same areas, such as Greater White-Fronted Goose (Anser albifrons Scopoli) and Greylag Goose (Anser anser L.). We asked the following questions: (i) Which habitat types are the most frequently used by Lesser White-fronted Goose and larger goose species? (ii) Is the different habitat preference of Lesser White-fronted Goose and larger goose species reflected in the seed content of their droppings? (iii) Are there seasonal differences between the seed content of spring and autumn droppings? We identified the most frequently used feeding habitats. We collected 40 droppings of Lesser White-fronted Goose and larger goose species per site in April and October 2012, in total we collected 720 droppings per species. Droppings were concentrated and spread on trays filled with sterilised potting soil. Samples were germinated in a greenhouse from April to November 2013. In total we germinated 21 plant species from the goose droppings, which suggests that goose species play an important role in seed dispersal. We found that Lesser White-fronted Goose dispersed more species typical to alkali habitats, and fewer weeds compared to larger goose species. Lesser White-fronted Goose and larger goose species used a wide range of feeding habitats, thus, they play an important role in dispersing seeds between habitats along a moisture gradient. Total species number and species number of plant functional groups were higher in autumn droppings. Seed content of the droppings suggests that Lesser White-fronted Goose is confined to natural habitats, thus for the effective protection of this critically endangered species it is crucial to preserve its natural feeding habitats.

In memoriam Zoltán Siroki (1906–1987)
3-14Views:116Zoltán Siroki (1906–1987) was a Hungarian agronomist and lecturer. His professional activity was connected mainly to Debrecen. Beside his widely known ornithological studies his floristic and fitocoenological data to Matricum, Crisicum and Nyírségense Hungarian regions are also important. Herbarium of Zoltán Siroki, consisting of ca. 20 000 specimens is a remarkable part of the Herbarium of Debrecen University (DE).

Contributions to the Atlas Florae Hungariae III.
122-146Views:479The current paper is the third one in the series aiming to contribute with new distribution data to the distribution maps published recently in Atlas Florae Hungariae. Current occurrence data of 558 vascular plant taxa from 186 flora mapping quadrates (CEU) are presented. New records are indicated from different regions of Hungary; however, most occurrences are located in the North Hungarian Mts. Occurrence data of rare native taxa (e.g. Marsilea quadrifolia, Salicornia prostrata, Stellaria palustris, Potentilla patula, Althaea cannabina, Lythrum tribracteatum, Ajuga laxmannii, Plantago schwarzenbergiana, Alisma gramineum, Gagea bohemica, G. szovitsii), rare or data-deficient alien taxa (e.g. Chorispora tenella, Thladiantha dubia, Senecio vernalis) as well as frequent but more or less underrepresented taxa (e.g. Scleranthus annuus, Vicia hirsuta, V. lathyroides) are also enumerated. In case of the most common species we provided the CEU codes only.

Contributions to the flora of kurgans in the Middle Tisza region
94–105Views:541Kurgans are ancient burial mounds built by nomadic steppic cultures. Embedded in the heavily transformed landscapes of the Carpathian Basin they often serve as last refuges for rare and endangered plant species. In our paper we publish floristic data collected on 82 kurgans located in the area of the Hortobágy National Park Directorate. Our dataset covers 64 CEU quarter quadrates, and the territory of 45 settlements. We provide data on 39 taxa that are either protected (e.g. Anchusa barrelieri, Centaurea solstitialis, Ranunculus illyricus and Phlomis tuberosa) or regionally rare (e.g. Aegilops cylindrica, Astragalus austriacus, Glaucium corniculatum and Trifolium diffusum). Our records demonstrate that kurgans have a vital role in maintaining the populations of rare and endangered grassland species even in transformed landscapes.

Contributions to the Atlas Florae Hungariae IX.
253–256Views:314The current paper is the 9th in the series aiming to provide new data to the distribution maps of Atlas Florae Hungariae. Data of 734 vascular plant taxa (from 222 flora mapping quadrats) are presented in this study. The new localities are spread across nearly the entire country; however, most of the data are from the North Hungarian Mts, the northern part of the Danube-Tisza Interfluve, the southern edge of Hanság, alongside River Maros and the Hortobágy. Altogether, 1632 new data records are presented in this paper. The list mainly contains rare and locally important native species, as well as species with uncertain native/alien status (e.g. Allium ursinum, Chamaecytisus triflorus, Cotoneaster niger, Cyperus pannonicus, Elatine triandra, Eleocharis acicularis, Eleocharis ovata, Erodium hoefftianum, Geranium lucidum, Globularia punctata, Hippuris vulgaris, Hottonia palustris, Lindernia procumbens, Marrubium vulgare, Ononis pusilla, Orobanche bartlingii, Orobanche cernua, Pisum elatius, Polycnemum majus, Polygonum graminifolium, Ribes nigrum, Schoenoplectus triqueter, Verbascum ×denudatum, Verbascum ×vidavense, Viola canina subsp. schultzii). We report new localities of expanding alien species (e.g. Amaranthus deflexus, Artemisia annua, Euphorbia maculata, Helminthia echioides, Hordeum jubatum, Impatiens glandulifera, Ipomoea purpurea, Mahonia aquifolium, Panicum riparium, Robinia viscosa, Rudbeckia hirta, Veronica peregrina, Yucca filamentosa) and mention a few rare, successfully “surviving” alien plants with nature conservation value (e.g. Acorus calamus, Monochoria korsakowii). Moreover, occurrences of common plants are presented when new to the Atlas Floraea Hungariae (e.g. Bromus hordeaceus, Symphytum officinale, Vicia tetrasperma).
