Introduction
I 'm dealing with the role of some environmental factors in shaping the composition and quantitative dynamics( i.e. biomass of rheoplankton- phytoplankton of the rivers from the Carpathian Basin.) I'm interested also in use of phytoplankton FGs sensu Reynolds for WFD/ EU related ecological quality assessment. Furthermore I am involved in research related to characterization of phytoplankton functional groups (i.e. FGs-sensu Reynolds) niche space in fluvial ecosystems.

Article
Full-text available
Assigning species to functional response groups in phytoplankton ecology reduces the number of functional units, which helps understand the processes that shape diversity and functioning of planktonic assemblages. Although the concept has become widespread in recent years, numerical characterization of the groups’ positions in the niche space remai...
Article
Full-text available
The impact of cumulative daily solar radiation (CDSR) on the biomass of river phytoplankton (Chl-a) in the growing season was studied using a large dataset of rivers in the Carpathian Basin. The amount of solar radiation was cumulated over the range of 1–60 days. The CDSR–Chl-a relationship could be described by linear regression and appeared to be...
Article
While phytoplankton studies on large potamal rivers have increased in number in recent years, upper river sections have received considerably less attention. However, in order to better understand processes that govern the development of dominance of euplanktonic elements in the lower river sections, detailed studies of the upstream areas are neces...
Article
Hydromorphological and chemical properties of water bodies have pronounced influence on the occurrence and distribution of biological elements in the aquatic ecosystems. Based on a series of abiotic characteristics, seventeen lake types were established in Hungary for management purposes. Benthic diatom assemblages were studied in shallow standing...

Míg a szabad szemmel látható állat-, illetve növényvilággal kapcsolatos ismeretterjesztés széleskörűvé vált, addig a mikroszkopikus világ tudományos igényű ismeretterjesztő bemutatására kevés példát találni. Hagyományteremtő céllal 2015-ben első alkalommal hirdette meg az Algológus Fórum az „Év Algája” internetes szavazást. A végső szavazásra javas...

Algal mass productions are widespread events throughout the world. Most research deals with the environmental impact, ecology and toxicity of these phenomena, but the algae are also promising sources of bioactive natural products, and also are potential food additives. In the current study, we aimed to characterize the carotenoid composition of thr...

As lake biota are basically determined by hydromorphological characteristics of the lake basin, establishment of a lake typology is the first step in lake quality assessment and management. Based on descriptor variables (size, depth, lake bed material, water-regime and macrophyte coverage), 16 hydromorphological lake-types were established for the...
Article
Full-text available
The restoration and management of shallow, pond-like systems are hindered by limitations in the applicability of the well-known models describing the relationship between nutrients and lake phytoplankton biomass in higher ranges of nutrient concentration. Trophic models for naturally eutrophic small, shallow, endorheic lakes have not yet been devel...

ABSTRACT: Anisops sardeus sardeus Herrich-Schaeffer 1849, is a common backswimmer to the Mediterranean region in Europe. During 2010 and 2011 it was collected as a new species from Hungary. It was found from 16 waterbodies, which are characterized by different chemical composition. Two occurrences were published in 2010, eleven new results were giv...
Article
The unicellular alga Prymnesium parvum has been responsible for toxic incidents with severe ecological impacts in many parts of the world, and causes massive fish kills worldwide. Recently the haptophyte microalgae have caused water-bloom (4.3 × 104 cells ml−1) in 6 fish ponds with high conductivity in Hungary, and caused fish mortality with typica...

New faunistical records of 80 aquatic Coleoptera and 14 aquatic and semiaquatic Heteroptera species from 38 sampling sites of the southern part of the Great Hungarian Plain are given. The samples were taken in 2009, mainly on two dates per sites, according to monitoring programs related to Water Framework Directive and AQEM protocol. Hydroporus obs...

The phytoplankton database of the Middle Danube Basin was analysed and evaluated in order to describe the characteristic algal assemblages of the rivers. The dataset were extracted from the database of the Hungarian monitoring network and academic istitutions. We implemented the Kohonen Self Organizing Map (SOM) method by which we can visualize the...

The major aim of our project is to better understand environmental constraint shaping the rheoplankton functional composition in the rivers of the Carpathian Basin, Hungary). We are mainly interested in the functional group composition (FG) of river phytoplankton sensu Reynolds (Reynolds et al. 2002; Borics et al. 2007; Padisák et al. 2009) and characterization of niche space of FGs sensu Reynolds using the OMI approach (for details see; Doledec et al. 2000). We intend to answer the role of FGs niche charateristics (i.e breadth and position) may play in the regional occupancy of phytoplankton FGs. Further plans related to the project are under development phase. Preliminary results; a, we could identify habitat template characteristics of each riverine phytoplankton functional group; and therefore we provide niche characteristics (i.e niche position and breadth) for the occurrence of functional groups under specific set of environmental conditions. b, all the identified FGs could be merged in six functional niche groups. c, we demonstrated that niche characteristics may play important role in the regional occupancy of riverine phytoplankton FGs, and these are related weakly to each other! d,We showed, that niche breadth and niche position of rheoplankton (i.e. notion proposed for phytoplankton taxa of rvers in rivers) FGs have similar importance in the regional distribution of FGs . e,we concluded that niche space breadth and position role in the regional occupancy .distribution can be separated as they were weakly related to each other. for details see our published article here and https://academic.oup.com/plankt/article/42/3/355/5837349 now already with open access Some ideas about our future plans , aims and concepts . We aim to answer whether niche characteristics of FGs differ significantly among different river typology classes of Hungarian lowland rivers. Furthermore, we want to answer whether niche characteristics of FGs show considerable changes along the longitudinal sections of Hungarian large rivers (i.e.River Danube, River Tisza drainage area). And so on...... We hope that ; Our final project results can be expanded later to further watersheds of the rivers or watersheds from Europe ,and even to other temperate zones of the Continents. and that characterization of niche space of phytoplankton taxa or FGs can expand our ability to understand what environmental factor can be considered essential for occurrence, regional distribution and even ( reccuring and non-reccuring) successional dynamics of phytoplankton taxa or FGs in the rivers.
