Borovec, Jakub ; Hejzlar, Josef ; Znachor, Petr ; Nedoma, Jiří ; Čtvrtlíková, Martina ; Blabolil, Petr ; Říha, Milan ; Kubečka, Jan ; Ricard, Daniel ; Matěna, Josef
Methodology for the assessment of the ecological potential of heavily modified and artificial water bodies was developed, including water body typology. The selection of indicator metrics was based on statistical analyses of the sensitivity of each of the indicators towards the most significant stressor – eutrophication. According to these results, biological communities and their indicators were selected to comply with the requirements set forth in the Water Framework Directive (2000/60/EC).

Methodology for the assessment of the ecological potential of heavily modified and artificial water bodies of the lacustrine type was developer, including also typology of water bodies. The selection of indicator metrics was based on statistical analyses of the sensitivity of each of the indicators towards the most significant stressor – eutrophication. According to these results, biological communities and their indicators were selected to comply with the requirements of the Water Framework Directive (2000/60/EC).

The first Czech methodology for the assessment of ecological potential of heavily modified water bodies and artificial water bodies based on fish communities was developed. The first step of developing the methodology was preparing the typology of water bodies. The typology distinguishes between water bodies of different altitudes and with and without thermal stratification. Fish were sampled by multimesh gillnets following European standard procedures. The selection of fish metrics was based on statistical analyses in which metrics (fish community indicators) were correlated with the most common stressor – eutrophication. The analysis detected several sensitive metrics (metrics showing the best correlation with the stressor) in which ecological class boundaries were set. Afterwards, combination of sensitive metrics was used for calculation of the ecological quality ratio (EQR) for each of the reservoir sampled. The EQR expresses the deviation between a reservoir’s current ecological status and its maximum potential. The next step consisted of validating the EQR with an independent pressure index and verifying the time stability of ecological potential assessment. The metrics used in the methodology fulfill all the obligations set forth in the Water Framework Directive (2000/60/EC), which include assessment of the composition, abundance and age structure of fish fauna.

Cílem projektu je posouzení vlivu emisí škodlivin z provozu motorových vozidel na kvalitu ovzduší v sídelních aglomeracích (Praha, Ostrava). Vypracování a optimalizace metodiky modelového hodnocení kvality ovzduší respektující skladbu a intenzitu silniční dopravy. Posouzení kvality ovzduší z hlediska limitních hodnot platných i připravovaných v EU. Návrh systému hodnocení zdravotních rizik pro vybrané anorganické a organické polutanty v ovzduší. Návrh emisních faktorů charakterizujících dopravu v ČR. Posouzení změn v kvalitě ovzduší v zájmových územích v důsledku variantních řešení rozvoje silniční dopravy (alternativní použití plynných paliv, vybavení a technický stav vozidel, změny ve složení a intenzitě dopravního proudu). Hodnocení emisí a imisí znečišťujících látek charakteristikách pro automobilovou dopravu - CO, NOx, PM10, polyaromatické uhlovodíky, těkavé uhlovodíky, aldehydy. První část zprávy (část A) obsahuje souhrn literárních poznatků z výše uvedeným tematickým okruhům. Dále jsou uvedeny dva vypracované modely a popsána jejich konstrukce.
Dynamics of fish spatial distribution in reservoirs
ŘÍHA, Milan
This dissertation thesis focuses on several aspects of fish ecology in reservoirs and the methodology of their sampling. It is divided to three parts. The first part focuses on the dynamics of fish distribution throughout the seasons and between day and night. The second part deals with the efficiency and the selectivity of the beach seine net, trawl and purse seine net. The third part describes the long-term development of fish populations in the Římov Reservoir.
