These habitats are commonly used for grazing or hay production for livestock. However, regular mowing can influence these habitats, potentially leading to significant repercussions for the animals residing within them. In order to investigate the effects of land management practices, we conducted an experimental study to compare snail communities in mowed and unmowed wet meadows in northern Hungary. We found that overall, mowing decreases snail populations, as well as species richness and diversity. Thus, our results suggest that routine mowing of wet meadows is deleterious to their snail communities. Based on these results, we suggest that designated patches of meadows that are regularly managed should be left uncultivated in their natural state. These patches can serve as potential colonization sites, facilitating the restoration of the entire meadow’s ecological balance.}, keywords = {Biodiversity; ABUNDANCE; conservation biology; Natural resources management; Gastropoda}, year = {2024}, eissn = {2167-8359}, orcid-numbers = {Bán, Miklós/0000-0002-6275-7928; Barta, Zoltán/0000-0002-7121-9865} } @article{MTMT:34839516, title = {Aquatic vegetation mapping with UAS-cameras considering phenotypes}, url = {https://m2.mtmt.hu/api/publication/34839516}, author = {Szabó, Loránd and Bertalan, László and Szabó, Gergely and Grigorszky, István and Somlyai, Imre and Dévai, György and Nagy, Sándor Alex and Holb, Imre and Szabó, Szilárd}, doi = {10.1016/j.ecoinf.2024.102624}, journal-iso = {ECOL INFORM}, journal = {ECOLOGICAL INFORMATICS}, unique-id = {34839516}, issn = {1574-9541}, abstract = {Aquatic vegetation species at the genus level in an oxbow lake were identified in Hungary based on a multispectral Uncrewed Aerial System (UAS ) survey within an elongated oxbow lake area of the Tisza River under continental climate.

With the advent of cavity technology, the question arises how the presence of quantum light affects the ionization of molecules. As the ionization spectrum is recorded from the ground state of the neutral molecule, it is usually possible to choose cavities which do not change the ground state of the target, but can have a significant impact on the ion and the ionization spectrum. Particularly interesting are cases where the produced ion exhibits conical intersections between its close-lying electronic states which is known to give rise to substantial nonadiabatic effects. We demonstrate by an explicit realistic example that vibrational modes not relevant in the absence of the cavity do play a decisive role when the molecule is in the cavity. In this example, dynamical symmetry breaking is responsible for the coupling between the ion and the cavity and the high spatial symmetry enables a control of their activity via the molecular orientation relative to the cavity field polarization. Significant impact on the spectrum by the cavity is found and shown to even substantially increase when less symmetric molecules are considered.}, keywords = {CAVITY; Ionization spectrum}, year = {2024}, pages = {4655-4661}, orcid-numbers = {Fábri, Csaba/0000-0001-9746-1548; Cederbaum, Lorenz S./0000-0002-4598-0650; Vibók, Ágnes/0000-0001-6821-9525} } @article{MTMT:34832088, title = {Exploring the interplay between the core microbiota, physicochemical factors, agrobiochemical cycles in the soil of the historic tokaj mád wine region}, url = {https://m2.mtmt.hu/api/publication/34832088}, author = {Gálné Remenyik, Judit and Csige, László and Dávid, Péter and Fauszt, Péter and Szilágyi-Rácz, Anna Anita and Szőllősi, Erzsébet and Bacsó, Zsófia Réka and Szepsy Jnr, István and Molnár, Krisztina and Rácz, Csaba and Fidler, Gábor and Kállai, Zoltán and Stündl, László and Dobos, Attila Csaba and Paholcsek, Melinda}, doi = {10.1371/journal.pone.0300563}, journal-iso = {PLOS ONE}, journal = {PLOS ONE}, volume = {19}, unique-id = {34832088}, issn = {1932-6203}, abstract = {A Hungarian survey of Tokaj-Mád vineyards was conducted. Shotgun metabarcoding was applied to decipher the microbial-terroir. The results of 60 soil samples showed that there were three dominant fungal phyla, Ascomycota 66.36% ± 15.26%, Basidiomycota 18.78% ± 14.90%, Mucoromycota 11.89% ± 8.99%, representing 97% of operational taxonomic units (OTUs). Mutual interactions between microbiota diversity and soil physicochemical parameters were revealed. Principal component analysis showed descriptive clustering patterns of microbial taxonomy and resistance gene profiles in the case of the four historic vineyards (Szent Tamás, Király, Betsek, Nyúlászó). Linear discriminant analysis effect size was performed, revealing pronounced shifts in community taxonomy based on soil physicochemical properties. Twelve clades exhibited the most significant shifts (LDA > 4.0), including the phyla Verrucomicrobia , Bacteroidetes , Chloroflexi , and Rokubacteria , the classes Acidobacteria , Deltaproteobacteria , Gemmatimonadetes , and Betaproteobacteria , the order Sphingomonadales , Hypomicrobiales , as well as the family Sphingomonadaceae and the genus Sphingomonas . Three out of the four historic vineyards exhibited the highest occurrences of the bacterial genus Bradyrhizobium , known for its positive influence on plant development and physiology through the secretion of steroid phytohormones. During ripening, the taxonomical composition of the soil fungal microbiota clustered into distinct groups depending on altitude, differences that were not reflected in bacteriomes. Network analyses were performed to unravel changes in fungal interactiomes when comparing postveraison and preharvest samples. In addition to the arbuscular mycorrhiza Glomeraceae , the families Mycosphaerellacae and Rhyzopodaceae and the class Agaricomycetes were found to have important roles in maintaining soil microbial community resilience. Functional metagenomics showed that the soil Na content stimulated several of the microbiota-related agrobiogeochemical cycles, such as nitrogen and sulphur metabolism; steroid, bisphenol, toluene, dioxin and atrazine degradation and the synthesis of folate.}, year = {2024}, eissn = {1932-6203}, orcid-numbers = {Szilágyi-Rácz, Anna Anita/0000-0003-3612-3574; Molnár, Krisztina/0000-0001-6203-6154; Rácz, Csaba/0000-0002-0307-6508; Dobos, Attila Csaba/0000-0001-7904-2155} } @article{MTMT:34831253, title = {Synthesis of multiple layers of alternating ZnO and TiO2 using atomic layer deposition and their optical characterization}, url = {https://m2.mtmt.hu/api/publication/34831253}, author = {Fouad, S.S. and Atyia, H.E. and Baradács, Eszter and Erdélyi, Zoltán and Mehta, N.}, doi = {10.1016/j.optmat.2024.115368}, journal-iso = {OPT MATER}, journal = {OPTICAL MATERIALS}, volume = {151}, unique-id = {34831253}, issn = {0925-3467}, abstract = {We report the optical characterization of bi-layer and quadri-layers of TiO2/ZnO transparent oxide films having a net thickness of 100 nm. The atomic layer deposition (ALD) was used to grow these multiple-layered films. We examined their optical properties to understand the impact of the number of layers. The grazing incidence X-ray diffraction (GIXRD) was used to assess the microstructure of the films, which showed that the ZnO layers were polycrystalline, while the TiO2 layers were (X-ray) amorphous. The optical transmission and reflection spectra of the investigated films were recorded in the range of 150–2500 nm at room temperature. The refractive index (n), extinction coefficient (k), real and imaginary parts of the dielectric constant, optical conductivity, and loss factor agree well with those of other amorphous oxides. It was established that the indirect allowed optical transitions are favorable and the optical gap (Eg) increases from 3.03 eV to 3.14 eV as the number of layers increases. The contribution of polarizability (ξ) and electrical susceptibility (χe) to the dielectric constant was also discussed. The relation between the relative density (D) and the porosity (Pro) with the crystalline quality, layer thickness, and the number of layers was also estimated.
