Airborne Laser Scanning (ALS) is a promising data source for developing indicators of 3D vegetation structure, but derived metrics are often not compared with 3D structural field measurements and the acquisition of ALS data is rarely standardized across different remote sensing surveys. Here, we compare a set of Light Detection And Ranging (LiDAR) metrics derived from ALS datasets with varying characteristics to a standardized set of field measurements of vegetation height, biomass and Leaf Area Index (LAI) across three Hungarian lakes (Lake Balaton, Lake Fert.o and Lake Tisza). The ALS datasets differed in whether the recording type was full waveform (FWF) or discrete return, and in their point density (4 pt/m(2) and 21 pt/m(2)). A total of eight LiDAR metrics captured radiometric information as well as descriptors of vegetation cover, height and vertical variability. Multivariate regression models with field-based measurements of vegetation height, biomass or LAI as response variable and LiDAR metrics as predictors showed major differences between ALS recording types, and were affected by differences in spatial resolution, temporal offset and seasonality between field and ALS data acquisition. Vegetation height could be estimated with high to intermediate accuracy (FWF ALS data only: R-2 = 0.84; combination of ALS datasets: R-2 = 0.67), demonstrating its potential as a robust indicator of 3D vegetation structure across different ALS datasets. In contrast, the estimation of biomass and LAI in these wetlands was sensitive to variation in ALS characteristics and to the discrepancies between field and ALS data in terms of spatial resolution, temporal offset and seasonality (biomass: R-2 = 0.20-0.22; LAI: R-2 = 0.08-0.30). We recommend the use of FWF ALS data within wetlands because it captures more vegetation structural details in dense reed and marshland vegetation. We further suggest that ecologists and remote sensing scientist should better coordinate the simultaneous and standardized acquisition of field and ALS data for testing the robustness of quantitative descriptors of vegetation cover, height and vertical variability within wetlands. This is important for establishing operational and spatially contiguous ALS-based indicators of 3D ecosystem structure across wetlands.}, keywords = {HEIGHT; BIOMASS; reedbeds; LAI; Full waveform ALS; Discrete return ALS; Marshlands}, year = {2021}, eissn = {1872-7034}, orcid-numbers = {Zlinszky, András/0000-0002-9717-0043} } @article{MTMT:31958429, title = {Electron & Biomass Dynamics of Cyanothece Under Interacting Nitrogen & Carbon Limitations}, url = {https://m2.mtmt.hu/api/publication/31958429}, author = {Rabouille, Sophie and Campbell, Douglas A. and Masuda, Takako and Zavřel, Tomáš and Bernát, Gábor and Polerecky, Lubos and Halsey, Kimberly and Eichner, Meri and Kotabová, Eva and Stephan, Susanne and Lukeš, Martin and Claquin, Pascal and Bonomi-Barufi, José and Lombardi, Ana Teresa and Červený, Jan and Suggett, David J. and Giordano, Mario and Kromkamp, Jacco C. and Prášil, Ondřej}, doi = {10.3389/fmicb.2021.617802}, journal-iso = {FRONT MICROBIOL}, journal = {FRONTIERS IN MICROBIOLOGY}, volume = {12}, unique-id = {31958429}, issn = {1664-302X}, year = {2021}, eissn = {1664-302X}, orcid-numbers = {Bernát, Gábor/0000-0001-6147-9391} } @article{MTMT:31920580, title = {Photomorphogenesis in the Picocyanobacterium Cyanobium gracile Includes Increased Phycobilisome Abundance Under Blue Light, Phycobilisome Decoupling Under Near Far-Red Light, and Wavelength-Specific Photoprotective Strategies}, url = {https://m2.mtmt.hu/api/publication/31920580}, author = {Bernát, Gábor and Zavřel, Tomáš and Kotabová, Eva and Kovács, László and Steinbach, Gábor and Vörös, Lajos and Prášil, Ondřej and Somogyi, Boglárka and Tóth, Viktor R.}, doi = {10.3389/fpls.2021.612302}, journal-iso = {FRONT PLANT SCI}, journal = {FRONTIERS IN PLANT SCIENCE}, volume = {12}, unique-id = {31920580}, issn = {1664-462X}, year = {2021}, eissn = {1664-462X}, orcid-numbers = {Bernát, Gábor/0000-0001-6147-9391; Steinbach, Gábor/0000-0001-7137-7030} } @article{MTMT:31847645, title = {Temporal Patterns and Intra- and Inter-Cellular Variability in Carbon and Nitrogen Assimilation by the Unicellular Cyanobacterium Cyanothece sp.

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} }
