Although, the locality has been known for centuries, the coprolites have not been investigated in detail. We describe these fossils and explore their palaeoecological significance. Coprolites were examined with thin sections, X-ray powder diffraction and computed tomography. Their surface is mostly smooth, desiccation cracks were not observed. All coprolites mainly consist of apatite, indicating most probably a carnivorous diet. No evidence of herbivory has been found so far. The coprolites contain remains belonging to several groups: ostracod carapaces, bivalve shells, vertebrae from bony fishes, fish scales, as well as teeth. The CT scans show inhomogeneities in the matrix; however, in most cases they do not reliably indicate inclusions. The taphonomical features suggest rapid burial and most likely an aquatic origin. The spiral morphotype could be attributed to fishes with spiral intestinal valves. Teeth of reef-associated fish taxa indicate Badenian age for some specimens, though the coprolite assemblage might include older and younger specimens as well.}, keywords = {Lake Pannon; Paratethys; Miocene; VERTEBRATE COPROLITES; coprolite taphonomy}, year = {2025}, eissn = {1029-2381}, pages = {663-678}, orcid-numbers = {Sebe, Krisztina/0000-0002-4647-2199; Virág, Attila/0000-0002-5530-0065; Botfalvai, Gábor/0000-0002-5479-9036} } @article{MTMT:35203216, title = {Testing treecbh in Central European forests: an R package for crown base height detection using high-resolution aerial laser-scanned data}, url = {https://m2.mtmt.hu/api/publication/35203216}, author = {Diószegi, Gergő and Abriha-Molnár, Vanda Éva and Nagy, Loránd Attila and Enyedi, Péter and Török, Péter and Szabó, Szilárd}, doi = {10.1093/forestry/cpae044}, journal-iso = {FORESTRY}, journal = {FORESTRY}, volume = {98}, unique-id = {35203216}, issn = {0015-752X}, abstract = {Accurate information regarding tree canopy characteristics is crucial for forest management, but it is often difficult to assess. This study presents an innovative framework designed for crown base height (CBH) detection using high-resolution laser-scanned data, with a specific focus on individual trees within forests. The framework comprises three key steps: (i) segmenting the input tree point cloud to identify the tree trunk and its branches using the treesio software; (ii) applying vertical cross-sectional K-means clustering to cluster the identified tree and to define the elevation threshold for removing low-lying understory vegetation; (iii) employing a novel 2D kernel method for detecting CBH after eliminating low-lying understory vegetation. The 2D kernel method, developed for broadleaf forests using leaf-off airborne laser scanning (ALS) data, underpins the treecbh tool. This tool features a visual CBH adjustment component that shows a 2D profile plot of the tree point cloud, and suggests a CBH value for user approval or adjustment. To evaluate accuracy, in situ measured CBH data from five forest plots in Germany and Hungary with varied species compositions were used. ALS data were collected during leaf-off conditions for the two Hungarian plots and during leaf-on conditions for the three German plots. Leaf-off terrestrial laser-scanned data from individual trees were also used in the accuracy assessment. A sensitivity analysis using random point decimation was conducted on the terrestrial laser-scanned data to assess treecbh’s sensitivity to point density. The initial results exhibited matching rates of 45% and 60% for leaf-off ALS plots, which significantly improved to 71% and 77%, respectively, when using the visual CBH adjustment feature of the tool. The leaf-on ALS results demonstrated matching rates between 24% and 33%, whereas the CBHs of individual terrestrial laser-scanned trees could be detected with 93% accuracy in visual mode. It was observed that treecbh operates effectively when the input ALS data have a minimum point density of 20 pts/, with its optimal performance achieved at 110 pts/. These findings indicated treecbh’s sensitivity to ALS data quality, scanning season (leaf-on and leaf-off), and point density. This sensitivity can be effectively mitigated in the case of leaf-off ALS data by utilizing the visual CBH adjustment feature of the tool.}, keywords = {crown base height detection; tree isolation}, year = {2025}, eissn = {1464-3626}, pages = {365-379}, orcid-numbers = {Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:35390822, title = {Relationship between petrography and geomechanical properties of the sandstone: A case study from Wadi Halfa, North Sudan}, url = {https://m2.mtmt.hu/api/publication/35390822}, author = {Daoud, Abazar and Abdelkader, Mohamed M. and Sediek, Kadry N. and Elsharief, Ahmed M. and Rashed, Mohamed A. and Elamein, Abdelaziz M. and Abdalrahiem, Khaled O. and Rózsa, Péter}, doi = {10.1556/1848.2024.00883}, journal-iso = {INT REV APPL SCI ENG}, journal = {INTERNATIONAL REVIEW OF APPLIED SCIENCES AND ENGINEERING}, volume = {16}, unique-id = {35390822}, issn = {2062-0810}, abstract = {The investigation of the effect of petrography and diagenetic features on the geomechanical properties of the sandstone and their relationship to rock failure are of vital importance for different construction projects.

The sandstone is dominantly composed of monocrystalline quartz grains (60%) accompanied by some polycrystalline quartz, feldspars, lithic fragments, micas, and heavy minerals. Iron oxides are the main type of cementing materials (14%), with some (2%) of carbonates and clay minerals. The average porosity of all studied samples is 12%. The compressive strength ranges widely, influenced by weathering, grain size, cementing materials, and bedding planes. The uniaxial compressive strength is more influenced by wetting when the load is parallel to bedding planes. Sandstone anisotropy is suggested by a U-shaped curve, with lower values at 45° and higher values at 90° and 0°. The geomechanical behavior of rocks masses in Wadi Halfa was evaluated through a combination of field and laboratory analyses which revealed a variable Rock Mass Rating (RMR) ranging from 58 to 92 and a Geological Strength Index (GSI) ranging from 33 to 61.}, year = {2025}, eissn = {2063-4269}, pages = {193-209} } @article{MTMT:35425326, title = {Az életminőség és a belső vándorlás hosszú távú területi összefüggéseinek vizsgálata Magyarországon a dualizmus korától napjainkig (1910-2022)}, url = {https://m2.mtmt.hu/api/publication/35425326}, author = {Pénzes, János and Szilágyi, Zsolt and Kiss, János Péter}, doi = {10.1556/2065.186.2025.6.18}, journal-iso = {MAGYAR TUDOMÁNY}, journal = {MAGYAR TUDOMÁNY}, volume = {186}, unique-id = {35425326}, issn = {0025-0325}, abstract = {Vizsgálatunk során több időmetszetben elemeztük a települési szintre adaptált HDI- (Human Development Index) mutatót, valamint a megelőző időszak belső vándorlási egyenlegeit.

The availability of free, high-resolution satellite imagery and advanced data mining techniques offers new opportunities for efficient soil property assessment. This study aimed to evaluate the potential utility of multi-season PlanetScope imagery to predict soil organic carbon (SOC), pH, and calcium carbonate (CaCO 3 ). Using random sampling, 121 topsoil samples (0–30 cm depth) were collected with an auger across grasslands, bare soil, and eroded areas within a typical grazing land use. Three data mining techniques: random forest (RF), extreme gradient boosting (XGB), and support vector machines (SVM), were applied and evaluated using a 10-fold cross-validation. The results indicated that multi-season spectral covariates considerably improved the accuracy of the target soil properties compared to single-season imagery. SVM was the most effective algorithm for predicting SOC, achieving a root mean square error (RMSE) of 0.52%, mean absolute error (MAE) of 0.24%, and R² of 0.92. RF was the best-performing algorithm for predicting soil pH (RMSE = 0.22, MAE = 0.17, and R² = 0.97) and CaCO 3 (RMSE = 0.55%, MAE = 0.42%, and R² = 0.96). While XGB failed to capture the variability in soil pH, the other models generated interpretable maps that accurately represented the distribution of soil properties across different land cover categories. The green-red vegetation index (GRVI) was the most critical covariate for predicting SOC, while elevation and the topographic wetness index (TWI) were key predictors for soil pH and CaCO 3 , respectively. This study underscores the potential of multi-season PlanetScope imagery for accurately predicting soil properties and recommends conducting similar studies in diverse geographical settings to validate these findings and develop more generalizable models.}, year = {2025}, eissn = {1865-0481}, orcid-numbers = {Bertalan, László/0000-0002-5963-2710; Szabó, Szilárd/0000-0002-2670-7384} } @article{MTMT:35749641, title = {Better management zoning with elevation than with three soil classifications in a periodically waterlogged plot}, url = {https://m2.mtmt.hu/api/publication/35749641}, author = {Tóth, Tibor and Szabó, Szilárd and Novák, Tibor József and Czigány, Szabolcs and Kocsis, Mihály and Makó, András and Gallai, Bence and Árvai, Mátyás and Mészáros, János and Balog, Kitti}, doi = {10.1016/j.geodrs.2025.e00927}, journal-iso = {GEODERMA REG}, journal = {GEODERMA REGIONAL}, volume = {40}, unique-id = {35749641}, issn = {2352-0094}, year = {2025}, eissn = {2352-0094}, orcid-numbers = {Szabó, Szilárd/0000-0002-2670-7384; Novák, Tibor József/0000-0002-5514-9035; Czigány, Szabolcs/0000-0002-9158-3162; Kocsis, Mihály/0000-0002-6210-6906; Makó, András/0000-0002-6169-6393; Mészáros, János/0000-0003-2604-3052; Balog, Kitti/0000-0001-9183-5529} }
