In 2021, three new sites of the species were discovered. In addition to these previously unknown occurrences, a detailed study of a roadside occurrence known for a longer time but not yet published was carried out. Main aim of our study was to find out how habitat management practices, such as mowing and winter-deicing effects seed mass and germination. Seeds collected earlier had significantly lower mass than those from later collections, suggesting that late-spring mowing would be optimal for the reproduction of M. alliacea. The type of mowing (chopping the stem into small pieces or cutting the stem at one point at few centimetres above ground) had no significant effect on seed germination but did have a significant effect on the seed mass. Seed mass deriving from whole individuals was significantly higher than seed mass of chopped individuals, suggesting, that traditional mowing methods are better than the use of modern lawnmowers for the survival of the species. The highest NaCl (used for winter-deicing) concentration where germination was observed was 0.75 m/m% (mass percentage), which is comparable with strongly saline soils in nature. The newly discovered sites were all disturbed, one of which was located on roadsides (paved and dirt roads) and two on embankments, suggesting that anthropogenic habitats could be optimal for the species, but the long-term survival depends on the management of these habitats.}, year = {2023}, eissn = {1365-3180}, pages = {237-245} } @article{MTMT:33782163, title = {The Role of Olive Groves in the Conservation of Mediterranean Orchids}, url = {https://m2.mtmt.hu/api/publication/33782163}, author = {Fekete, Réka and Vincze, Orsolya and Süveges , Kristóf and Bak, Henrietta Mária and Malkócs, Tamás and Löki, Viktor and Urgyán, Renáta and Molnár, V.

Our aim was to study the critical question of how endozoochory rates change throughout the annual cycle, and how this relates to plant life-form and phenology. Location Lake Velence, Hungary. Time period 2017-2018. Major taxa studied Mallard (Anas platyrhynchos), Angiospermae, Charophyta. Methods We studied waterfowl endozoochory, quantifying seeds and other diaspores dispersed by mallards by collecting faecal samples monthly (n(total) = 670) at a Hungarian lake. We tested the germinability of all seeds recovered from the faecal samples. Main conclusions We extracted 5,760 seeds representing 35 plant taxa from mallard faecal samples, and 40% of these seeds germinated successfully following gut passage. We found major differences between seasons in the species composition of the seeds recovered. The peak in species diversity and in abundance of terrestrial seeds coincided with the spring migration of mallards. Importantly, endozoochory was only strongly synchronized with seed production in submerged, but not in emergent or terrestrial plants, illustrating the potential for endozoochory of seeds ingested from the soil seed bank. Overall, our results suggest that endozoochory by migratory waterfowl is a strong and underestimated driver of plant distributions, and is likely to facilitate plant range shifts under climate change, and after introduction of alien species.}, keywords = {DISPERSAL; Phenology; wetland; seed bank; Waterfowl; Sesonality}, year = {2023}, eissn = {1466-8238}, pages = {70-82}, orcid-numbers = {Urgyán, Renáta/0000-0002-4307-5470; Lukács, Balázs András/0000-0002-3163-1281; Vincze, Orsolya/0000-0001-5789-2124; Green, Andy J./0000-0002-1268-4951} } @article{MTMT:33103443, title = {Native and alien poplar plantations are important habitats for terrestrial orchids}, url = {https://m2.mtmt.hu/api/publication/33103443}, author = {Süveges , Kristóf and Vincze, Orsolya and Löki, Viktor and Lovas-Kiss, Ádám and Takács, Attila and Fekete, Réka and Tüdősné Budai, Júlia and Molnár, V.

While they are most often considered of low environmental value, they have recently gained recognition for their multifaceted role in ecological engineering, such as carbon sinks, soil remediators or green energy producers. Nonetheless, the biodiversity of poplar plantations remains little known and largely overlooked. Here we conducted a systematic botanical survey of 232 poplar plantations within the Pannonian ecoregion (central Europe) in order to assess their plant diversity, with particular focus on terrestrial orchids. Our results highlight that almost 60% of poplar monocultures harbour terrestrial orchids, some with several thousand specimens. Overall, we documented the occurrence of 15 species of terrestrial orchids in the surveyed plantations, including taxa with limited distributions and a threatened conservation status. For instance, we report numerous new populations of Epipactis bugacenis and E. tallosii in poplar plantations, suggesting that the majority of these taxa occur in poplar monocultures within Hungary. We analysed and highlight soil chemistry and plantation characteristics that predict the occurrence and species richness of terrestrial orchids in poplar monocultures. The probability of orchids being present is highest in older and larger poplar plantations, characterized by high total organicmatter content and high soil pH.We conclude that plantations of native and alien poplar harbour valuable plant communities, including terrestrial orchids and other vascular plants of significant conservation importance. Using the knowledge generated here, we recommend delaying or partial harvest of poplar plantations to increase their conservation potential.}, keywords = {Orchidaceae; Biodiversity conservation; Vascular plants; Agroforestry; Anthropogenic habitats; Epipactis; Cephalanthera; poplar monocultures}, year = {2022}, eissn = {2570-950X}, pages = {429-445} } @article{MTMT:33017289, title = {Nyárfaültetvények orchideái – irodalmi áttekintés}, url = {https://m2.mtmt.hu/api/publication/33017289}, author = {Molnár, V.

The occurrence of 4 additional species in poplar plantations in 3 countries is proved by sources on the World Wide Web. The most widespread orchids in the poplar plantations are the rhizomatous, partial myco-heterotroph Cephalanthera and Epipactisspecies. Their importance is enhanced by the fact that most of the known populations of some species with a relatively narrow distribution range (Epipactis bugacensis, E. campeadorii, E. fibri, E. tallosii, E. zaupolensis) are known in poplar plantations. Cultivated poplar monocultures are likely to provide habitat for further orchids in other countries too. Most of the published papers are limited to floristic data from a single or a few plantations. Longer-term observations are only available from Poland, thanks to the work of W. Adamowski, and these suggest that populations may persist for decades and even increase dynamically. The size of orchid populations in some cases can reach thousands or even hundreds of thousands of individuals. Orchids can appear earliest in (4–)7–8 years old plantations. Very little is known about how the cultivation, structure, soil conditions and the poplar cultivars influence the presence of orchids. Mycorrhizal interactions of poplars and orchids may play a key role in this process, but the available knowledge is very limited. Furthermore, little is known about how the economic use of plantations can be reconciled with the long-term maintenance of orchid populations.}, keywords = {Orchidaceae; Anthropogenic habitats; Secondary habitats; plantation forestry; grey literature; apophytism; Populus x canadensis}, year = {2022}, eissn = {2064-4507}, pages = {102-117} } @article{MTMT:32893508, title = {Poplar plantations in Turkey: an overlooked habitat for orchids.

Közleményünkben szeretnénk felhívni a figyelmet a gazdasági célú nyárfaültetvényekre mint orchidea-élőhelyekre. 5 tartomány 8 tanulmányozott ültetvénye közül 6-ban fordultak elő orchideák, összesen 7 nemzetség 12 faját (Anacamptis elegans, A. fragrans, A. pyramidalis, Cephalanthera longifolia, C. damasonium, Epipactis helleborine, E. persica, Himantoglossum jankae, Ophrys apifera, O. oestrifera, Ophrys sp., Serapias feldwegiana) találtunk meg. Az átlagosan mindössze 0,27±0,21 hektár területű ültetvényekben 0–5 faj (átlag±szórás=1,88±1,80) jelenlétét regisztráltuk. Az orchideaállományok sűrűsége 0 és 355,6 példány/hektár között változott (átlag±szórás=88,95±124,6). Az ültetvényekben egyaránt előfordultak gumós és rizómás növekedési típusú orchideák, de többségben voltak az előbbiek: a megtalált orchideafajok közül 8 (67%), az egyedek közül 232 (94%) volt gumós. Az orchideás ültetvényekben az átlagos törzsátmérő 16,7 és 21,8 cm közötti volt. A tanulmányozott ültetvényekben nem tapasztaltuk orchideagumók gyűjtésének vagy túllegeltetésnek nyomait, ami hozzájárulhat ahhoz, hogy megfelelő élőhelyül szolgáljanak egyes orchideafajok számára. Figyelembe véve a nyárfaültetvények jelentős kiterjedését és területük várható további növekedését Törökországban, szerepüket az orchideák megőrzésében érdemesnek tűnik vizsgálni.}, year = {2022}, eissn = {2415-9662}, pages = {55-66} }
