At all these sites, small, shallow wet areas were found. Within the zooplankton community the Rotifera, Cladocera and Copepoda assemblages were investigated. The composition of the small crustacean group was poor with few species, with the juvenile forms (nauplii, copepodits) being characteristic. The rotifers provided the largest proportion of the zooplankton community regarding both abundance ratio and species richness. In the Rotifera assemblage more halobiont indicator species were found, next to which fresh- and saltwater, halophilic and marsh organisms occurred as well. This special, ambivalent species collection gives reason for a further examination and a detailed survey of this wet area, especially the ravine located in the alder grove.}, year = {2023}, pages = {52-59} } @{MTMT:34129312, title = {Discordant spatio-temporal dynamics of functional and phylogenetic diversity of rotiferan communities exposed to aquaculture effluent}, url = {https://m2.mtmt.hu/api/publication/34129312}, author = {Tóth, Flórián and Zsuga, Katalin and Kerepeczki, Éva and Kovács, Balázs and Magura, Tibor and Körmöczi, László and Lövei, Gábor}, doi = {10.5061/dryad.c2fqz61fn}, unique-id = {34129312}, year = {2023}, orcid-numbers = {Kovács, Balázs/0000-0003-1753-5098; Körmöczi, László/0000-0003-1027-3822} } @article{MTMT:32188140, title = {A Kákafoki Holt-Körös kerekesféreg közösségének diverzitásváltozásai akvakultúrából származó elfolyóvíz hatására}, url = {https://m2.mtmt.hu/api/publication/32188140}, author = {Tóth, Flórián and Zsuga, Katalin and Kerepeczki, Éva and Berzi-Nagy, László and Körmöczi, László and Lövei, Gábor}, journal-iso = {HALÁSZATFEJLESZTÉS}, journal = {HALÁSZATFEJLESZTÉS}, volume = {38}, unique-id = {32188140}, issn = {1219-4816}, year = {2021}, pages = {48-49}, orcid-numbers = {Körmöczi, László/0000-0003-1027-3822} } @article{MTMT:31984406, title = {Zooplankton Community Structure in Shallow Saline Steppe Inland Waters}, url = {https://m2.mtmt.hu/api/publication/31984406}, author = {Zsuga, Katalin and Zarina, Inelova and Boros, Emil}, doi = {10.3390/w13091164}, journal-iso = {WATER-SUI}, journal = {WATER}, volume = {13}, unique-id = {31984406}, abstract = {Abstract: Several shallow saline waters can be found in Central Asia in arid steppe climate, but our knowledge of their zooplankton community has been so far rather limited. The aim of our research was to provide data on the steppe zooplankton community in a large-scale regional study. Therefore, a baseline survey was carried out in 23 shallow inland waters of different salinity in Northern Kazakhstan. We measured the quantity and identified the taxonomic composition of zooplankton in the spring period and examined changes in community structure in correlation with salinity. Lesser salt concentration of the hyposaline–mesosaline waters was indicated by the presence of halophilic rotifer species: Brachionus asplanchnoides Br. dimidiatus, Br. plicatilis. Mesosaline and hypersaline waters were indicated by the presence of halobiont crustaceans: Moina salina, Arctodiaptomus salinus, Cletocamptus retrogressus. Very high concentration of salt was indicated by presence of Artemia alone which is the only group, that can tolerate and adapt to this extreme environment. In the hypersaline waterbodies at over 79 gL􀀀1 high TDS conditions a very simple tropical structure was found. Artemia playing monopolistic ecological function in the zooplankton community. We identified three characteristic groups of shallow inland saline waters based on their zooplankton composition.}, keywords = {Keywords: saline water; halophilic; halobiont zooplankton organisms; species richness; taxonomical diversity}, year = {2021}, eissn = {2073-4441} } @article{MTMT:31776926, title = {Exogenic production of bioactive filamentous biopolymer by monogonant rotifers}, url = {https://m2.mtmt.hu/api/publication/31776926}, author = {Datki, Zsolt László and Ács, Éva and Balázs, Evelin and Sovány, Tamás and Pannonhalminé Csóka, Ildikó and Zsuga, Katalin and Kálmán, János and Oláh, Zita}, doi = {10.1016/j.ecoenv.2020.111666}, journal-iso = {ECOTOX ENVIRON SAFE}, journal = {ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY}, volume = {208}, unique-id = {31776926}, issn = {0147-6513}, abstract = {The chemical ecology of rotifers has been little studied. A yet unknown property is presented within some monogonant rotifers, namely the ability to produce an exogenic filamentous biopolymer, named ‘Rotimer’. This rotifer-specific viscoelastic fiber was observed in six different freshwater monogonants (Euchlanis dilatata, Lecane bulla, Lepadella patella, Itura aurita, Colurella adriatica and Trichocerca iernis) in exception of four species. Induction of Rotimer secretion can only be achieved by mechanically irritating rotifer ciliate with administering different types (yeast cell skeleton, denatured BSA, epoxy, Carmine or urea crystals and micro-cellulose) and sizes (approx. from 2.5 to 50 μm diameter) of inert particles, as inductors or visualization by adhering particles. The thickness of this Rotimer is 33 ± 3 nm, detected by scanning electron microscope. This material has two structural formations (fiber or gluelike) in nano dimension. The existence of the novel adherent natural product becomes visible by forming a ‘Rotimer-Inductor Conglomerate’ (RIC) web structure within a few minutes. The RIC-producing capacity of animals, depends on viability, is significantly modified according to physiological-(depletion), drug- (toxin or stimulator) and environmental (temperature, salt content and pH) effects. The E. dilatata-produced RIC is affected by protein disruptors but is resistant to several chemical influences and its Rotimer component has an overwhelming cell (algae, yeast and human neuroblastoma) motility inhibitory effect, associated with low toxicity.

Changes in biodiversity of zooplankton communities is often used to assess the eects of such impacts. Rotifers are suitable for bioindication of water quality due to their fast reaction to environmental changes. We examined seasonal changes in the diversity of rotifer communities along a 3.5 km section of the biggest oxbow lake in the Tisza River basin, Hungary, that received inflow from an intensive tank-based aquaculture farm. We detected a species-rich rotifer community with 26 species. Using the Rényi one-parameter diversity index families, we found that biodiversity increased away from the point of inflow in spring, but after a summer transition period the situation became partially reversed during autumn. At the beginning of the study period, the nutrient-rich euent strengthened the dominance of common species, which decreased but did not disappear in summer. In autumn, the extra nutrient input delayed the decline of the rotifer community at the point of euent.}, year = {2020}, eissn = {2073-4441}, orcid-numbers = {Körmöczi, László/0000-0003-1027-3822} } @article{MTMT:31612918, title = {Halastavi zooplankton közösségi összetételében rejlő különbségek eltérő takarmányösszetevők használata mellett}, url = {https://m2.mtmt.hu/api/publication/31612918}, author = {Tóth, Flórián and Zsuga, Katalin and Kerepeczki, Éva and Berzi-Nagy, László and Jakabné Sándor, Zsuzsanna and Körmöczi, László}, journal-iso = {HALÁSZATFEJLESZTÉS}, journal = {HALÁSZATFEJLESZTÉS}, volume = {37}, unique-id = {31612918}, issn = {1219-4816}, year = {2020}, pages = {93-96}, orcid-numbers = {Jakabné Sándor, Zsuzsanna/0000-0002-5216-6964; Körmöczi, László/0000-0003-1027-3822} } @article{MTMT:31308083, title = {The Effect of Feed Composition on the Structure of Zooplankton Communities in Fishponds}, url = {https://m2.mtmt.hu/api/publication/31308083}, author = {Tóth, Flórián and Zsuga, Katalin and Kerepeczki, Éva and Berzi-Nagy, László and Jakabné Sándor, Zsuzsanna and Körmöczi, László}, doi = {10.3390/w12051338}, journal-iso = {WATER-SUI}, journal = {WATER}, volume = {12}, unique-id = {31308083}, abstract = {Abstract: With the intensification of aquaculture, the structure and dynamics of aquatic ecosystems are highly aected. At the same time, for a pond fish farmer, one of the most important tasks is to establish and maintain stable and favourable zooplankton populations. In this paper, we assess the eects of dierent supplementary feed types on zooplankton communities in freshwater fishponds. In an outdoor, experimental fishpond system, carp individuals of 2+ years of age were stocked and fed with either a fishmeal-based diet (FF), a plant meal containing experimental feed (PF) or cereals (CT). To compare the diversity of the zooplankton communities, we used the Shannon diversity index, and to assess the eects of environmental factors and the feed ingredients, we applied canonical correspondence analysis. We described the dynamics of zooplankton communities, where the biodiversity of rotifera and Crustacean communities showed temporal dierences. In order to examine the eects of feed ingredients, temporal clustering was applied. The dierent diets did not consistently alter the composition of zooplankton communities. Consequently, the plant meal containing experimental feed had no negative eect on the planktonic biodiversity, which makes it suitable as an alternative feed source for fishponds at the applied level.}, year = {2020}, eissn = {2073-4441}, pages = {1338}, orcid-numbers = {Jakabné Sándor, Zsuzsanna/0000-0002-5216-6964; Körmöczi, László/0000-0003-1027-3822} } @article{MTMT:31307540, title = {Seasonal Differences in Taxonomic Diversity of Rotifer Communities in a Hungarian Lowland Oxbow Lake Exposed to Aquaculture Effluent}, url = {https://m2.mtmt.hu/api/publication/31307540}, author = {Tóth, Flórián and Zsuga, Katalin and Kerepeczki, Éva and Berzi-Nagy, László and Körmöczi, László and Lövei, Gábor}, doi = {10.3390/w12051300}, journal-iso = {WATER-SUI}, journal = {WATER}, volume = {12}, unique-id = {31307540}, year = {2020}, eissn = {2073-4441}, orcid-numbers = {Körmöczi, László/0000-0003-1027-3822} }
