	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. Seven and 13 classes were discriminated using three different classification methods (Support Vector Machine [SVM], Random Forest [RF] , and Multivariate Adaptive Regression Splines [MARS]) using different input data in ten combinations: original spectral bands , spectral indices, Digital Surface Model (DSM) , and Haralick texture indices. We achieved a high (97.1%) overall accuracies (OAs) by applying the SVM classifier, but the RF performed only <1% worse, as it was represented in the first places of the classification rank before the MARS. The highest classification accuracies (>84% OA) were obtained using the most important variables derived by the Recursive Feature Elimination (RFE) method . The best classification required DSM as an input variable. The poorest classification performance belonged to the model that used only texture indices or spectral indices. On the class level, Stratoites aloides exhibit the lowest degree of separability compared to the other classes. Accordingly, we recommend using supplementary input data for the classifications beside s the original spectral bands, for example , DSM, spectral , and texture indices, as these variables significantly improve the classification accuracies in the proper combinations of the input variables .},

	abstract = {Juveniles of three cyprinids with various diets and habitat preferences were collected from the Szamos River (Hungary) during a period of pollution in November 2013: the herbivorous, benthic nase ( Chondrostoma nasus ), the benthivorous, benthic barbel ( Barbus barbus ), and the omnivorous, pelagic chub ( Squalius cephalus ). Our study aimed to assess the accumulation of these elements across species with varying diets and habitat preferences, as well as their potential role in biomonitoring efforts. The Ca, K, Mg, Na, Cd, Cr, Cu, Fe, Mn, Pb, Sr, and Zn concentration was analyzed in muscle, gills, and liver using MP-AES. The muscle and gill concentrations of Cr, Cu, Fe, and Zn increased with trophic level. At the same time, several differences were found among the trace element patterns related to habitat preferences. The trace elements, including Cd, Pb, and Zn, which exceeded threshold concentrations in the water, exhibited higher accumulations mainly in the muscle and gills of the pelagic chub. Furthermore, the elevated concentrations of trace elements in sediments (Cr, Cu, Mn) demonstrated higher accumulation in the benthic nase and barbel. Our findings show habitat preference as a key factor in juvenile bioindicator capability, advocating for the simultaneous use of pelagic and benthic juveniles to assess water and sediment pollution status.},

	abstract = {The significance of aquatic ecosystems is increasingly recognized, considering their
		conservation, recreational, and economic value. However, their sustainable management is complex
		and challenging, requiring a thorough understanding. Monitoring the condition and changes of habitats
		is crucial, which can be facilitated by analyzing the organisms and vegetation present in the area. To
		further refine the classification process, it may be important to disaggregate classes into phenophases,
		which can be supported by examining the Jeffries-Matusita distances. In the case study presented of the
		Rakamazi Nagy-Morotva, a multispectral UAS-based survey was conducted to assess the separability
		of classes. The results indicate that higher accuracy cannot be achieved with classes disaggregated into
		phenophases. However, based on the separability analysis, it may be worth considering the separation of
		only a few classes where high separability values are achieved, thus allowing for the production of more
		detailed land cover maps while maintaining thematic accuracy},
