We hypothesized that differences in N availability (N2 vs. combined N) would cause UCYN to shift strategies of intracellular N and C allocation. We used transmission electron microscopy and nanoscale secondary ion mass spectrometry imaging to track assimilation and intracellular allocation of 13C-labeled CO2 and 15N-labeled N2 or NO3 at different periods across a diel cycle in Cyanothece sp. ATCC 51142. We present new ideas on interpreting these imaging data, including the influences of pre-incubation cellular C and N contents and turnover rates of inclusion bodies. Within cultures growing diazotrophically, distinct subpopulations were detected that fixed N2 at night or in the morning. Additional significant within-population heterogeneity was likely caused by differences in the relative amounts of N assimilated into cyanophycin from sources external and internal to the cells. Whether growing on N2 or NO3, cells prioritized cyanophycin synthesis when N assimilation rates were highest. N assimilation in cells growing on NO3 switched from cyanophycin synthesis to protein synthesis, suggesting that once a cyanophycin quota is met, it is bypassed in favor of protein synthesis. Growth on NO3 also revealed that at night, there is a very low level of CO2 assimilation into polysaccharides simultaneous with their catabolism for protein synthesis. This study revealed multiple, detailed mechanisms underlying C and N management in Cyanothece that facilitate its success in dynamic aquatic environments.}, year = {2021}, eissn = {1664-302X}, orcid-numbers = {Bernát, Gábor/0000-0001-6147-9391} } @article{MTMT:31847554, title = {Elevated temperature results in higher compositional variability of pioneer phytoplankton communities in a mesocosm system}, url = {https://m2.mtmt.hu/api/publication/31847554}, author = {Pálffy, Károly and Kovács, Attila and Kardos, Vivien and Hausz, Imola and Boros, Gergely}, doi = {10.1093/plankt/fbab013}, journal-iso = {J PLANKTON RES}, journal = {JOURNAL OF PLANKTON RESEARCH}, volume = {43}, unique-id = {31847554}, issn = {0142-7873}, year = {2021}, eissn = {1464-3774}, pages = {142-155} } @article{MTMT:31679872, title = {Let your maps be fuzzy!—Class probabilities and floristic gradients as alternatives to crisp mapping for remote sensing of vegetation}, url = {https://m2.mtmt.hu/api/publication/31679872}, author = {Feilhauer, Hannes and Zlinszky, András and Kania, Adam and Foody, Giles M. and Doktor, Daniel and Lausch, Angela and Schmidtlein, Sebastian}, doi = {10.1002/rse2.188}, journal-iso = {REMOTE SENS ECOL CON}, journal = {REMOTE SENSING IN ECOLOGY AND CONSERVATION}, volume = {7}, unique-id = {31679872}, year = {2021}, eissn = {2056-3485}, pages = {292-305}, orcid-numbers = {Feilhauer, Hannes/0000-0001-5758-6303; Zlinszky, András/0000-0002-9717-0043; Foody, Giles M./0000-0001-6464-3054; Lausch, Angela/0000-0002-4490-7232} } @article{MTMT:31636077, title = {Planktonic and Benthic Bacterial Communities of the Largest Central European Shallow Lake, Lake Balaton and Its Main Inflow Zala River}, url = {https://m2.mtmt.hu/api/publication/31636077}, author = {Farkas, Milán and Kaszab, Edit and Radó, Júlia and Háhn, Judit and Tóth, Gergő and Harkai, Péter and Ferincz, Árpád and Lovász, Zsófia and Táncsics, András and Vörös, Lajos and Kriszt, Balázs and Szoboszlay, Sándor}, doi = {10.1007/s00284-020-02241-7}, journal-iso = {CURR MICROBIOL}, journal = {CURRENT MICROBIOLOGY}, volume = {77}, unique-id = {31636077}, issn = {0343-8651}, abstract = {Lake Balaton is the largest European shallow lake, which underwent cultural eutrophication in the ‘70–80s. Therefore, strict pollution control measures were introduced and the water quality has become meso-eutrophic since the millennium. Due to the touristic significance and change in trophic levels of the lake, numerous ecological studies were carried out, but none of them was focused on both benthic and planktonic microbial communities at the same time. In our study, an attempt was made to reveal the spatial bacterial heterogeneity of the Lake Balaton and Zala River by 16S rDNA terminal restriction fragment length polymorphism fingerprinting and Illumina amplicon sequencing methods in the summer of 2017. According to the molecular biology results, mostly well-known freshwater microorganisms, adapted to nutrient-poor conditions were found in the pelagic water column. The LD12 subclade member Fonsibacter ubiquis, the cyanobacterial Synechococcus sp. and unknown Verrucomicrobia species were abundant in the less nutrient-dense basins, while the hgcI clade members showed various distribution. In the estuary and in the nutrient-dense western part of the lake, some eutrophic conditions preferring cyanobacteria (filamentous Anabaena and Aphanizomenon species) were also detectable. The benthic microbial community showed higher diversity, according to the observed appearance of microorganisms adapted to the deeper, less aerated layers (e.g. members of Desulfobacteraceae, Nitrosomonadaceae).}, year = {2020}, eissn = {1432-0991}, pages = {4016-4028}, orcid-numbers = {Kaszab, Edit/0000-0002-5917-0464; Háhn, Judit/0000-0003-1787-5359; Tóth, Gergő/0000-0002-0302-2681; Harkai, Péter/0000-0002-6038-4961} } @inbook{MTMT:31607500, title = {A Balaton ábrázolása térképeken}, url = {https://m2.mtmt.hu/api/publication/31607500}, author = {Síkhegyi, Ferenc and Timár, Gábor and Brezsnyánszky, Károly and Galambos, Csilla and Zlinszky, András}, booktitle = {A Balaton kutatása Lóczy Lajos nyomdokán}, unique-id = {31607500}, year = {2020}, pages = {311-339}, orcid-numbers = {Timár, Gábor/0000-0001-9675-6192; Galambos, Csilla/0000-0002-6041-1800; Zlinszky, András/0000-0002-9717-0043} } @article{MTMT:31592032, title = {Interaction among bacterioplankton and macrophytes in shallow lakes with high macrophyte cover}, url = {https://m2.mtmt.hu/api/publication/31592032}, author = {Szabó-Tugyi, Nóra and Tóth, Viktor R.}, doi = {10.1007/s00027-020-00753-9}, journal-iso = {AQUAT SCI}, journal = {AQUATIC SCIENCES}, volume = {82}, unique-id = {31592032}, issn = {1015-1621}, year = {2020}, eissn = {1420-9055} } @article{MTMT:31529338, title = {Oligotrophication of Lake Balaton over a 20-year period and its implications for the relationship between phytoplankton and zooplankton biomass}, url = {https://m2.mtmt.hu/api/publication/31529338}, author = {Bernát, Gábor and Boross, Nóra and Somogyi, Boglárka and Vörös, Lajos and G.-Tóth, László and Boros, Gergely}, doi = {10.1007/s10750-020-04384-x}, journal-iso = {HYDROBIOLOGIA}, journal = {HYDROBIOLOGIA}, volume = {847}, unique-id = {31529338}, issn = {0018-8158}, year = {2020}, eissn = {1573-5117}, pages = {3999-4013}, orcid-numbers = {Bernát, Gábor/0000-0001-6147-9391} } @article{MTMT:31395623, title = {Photoautotrophic picoplankton – a review on their occurrence, role and diversity in Lake Balaton}, url = {https://m2.mtmt.hu/api/publication/31395623}, author = {Somogyi, Boglárka and Felföldi, Tamás and G.-Tóth, László and Bernát, Gábor and Vörös, Lajos}, doi = {10.1007/s42977-020-00030-8}, journal-iso = {BIOL FUTURA}, journal = {BIOLOGIA FUTURA}, volume = {71}, unique-id = {31395623}, issn = {2676-8615}, abstract = {Occurrence of the smallest phototrophic microorganisms (photoautotrophic picoplankton, APP) in Lake Balaton was discovered in the early 1980s. This triggered a series of systematic studies on APP and resulted in the setting of a unique long-term picoplankton dataset. In this review, we intend to summarize the obtained results and to give a new insight on APP ecology and diversity in Lake Balaton. According to the results, APP dynamics depends on trophic state, temperature, nutrient, and light availability, as well as grazing pressure. APP abundance in Lake Balaton decreased to a low level (1–2 × 105 cells mL−1) as a consequence of decreasing nutrient supply (oligotrophication) during the past more than two decades, and followed a characteristic seasonal dynamics with higher abundance values from spring to autumn than in winter. Concomitantly, however, the APP contribution to both phytoplankton biomass and primary production increased (up to 70% and 40–50%, respectively) during oligotrophication. Regarding annual pattern, picocyanobacteria are dominant from spring to autumn, while in winter, picoeukaryotes are the most abundant, most likely due to the different light and temperature optima of these groups. Within picocyanobacteria, single cells and microcolonies were both observed with mid-summer dominance of the latter which correlated well with the density of cladocerans. Community-level chromatic adaptation (i.e., dominance of phycoerythrin- or phycocyanin-rich forms) of planktonic picocyanobacteria was also found as a function of underwater light quality. Sequence analysis studies of APP in Lake Balaton revealed that both picocyanobacteria and picoeukaryotes represent a diverse and dynamic community consisting several freshwater genotypes (picocyanobacteria: Synechococcus, Cyanobium; picoeukaryotes: Choricystis, Stichococcus, Mychonastes, Nannochloris, and Nannochloropsis).}, year = {2020}, eissn = {2676-8607}, pages = {371-382}, orcid-numbers = {Felföldi, Tamás/0000-0003-2009-2478; Bernát, Gábor/0000-0001-6147-9391} }
