1 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund DIATOM PHYTOBENTHOS IN RIVERS OF WEL BASIN – PRELIMINARY RESULTS Joanna Picińska-Fałtynowicz INSTITUTE OF METEOROLOGY AND WATER MANAGEMENT WROCŁAW BRANCH, DEPARTMENT OF ECOLOGY

2 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund Diatom phytobenthos river types I – Mountain streams 1. Siliceous stream of Tatry Mts. 2. Calcareous stream of Tatry Mts. 3. Stream of Sudety Mts. III – Mid-altitude siliceous streams 4. Mid-altitude siliceous stream with coarse substratum 5. Mid-altitude siliceous stream with fine substratum IV – Mid-altitude calcareous rivers 9. Small mid-altitude calcareous river 14. Small flysch river 15. Medium mid-altitude eastern river II – Mid-altitude calcareous streams 6. Mid-altitude calcareous stream with fine substratum 7. Mid-altitude calcareous stream with coarse substratum 12. Flysch stream V – Mid-altitude siliceous rivers 8. Small mid-altitude siliceous river 10. Medium mid-altitude siliceous river VI – Lowland streams and small rivers 16. Lowland clayey or loess stream 17. Lowland sandy stream 18. Lowland gravely stream 23. Organic stream 26. River in a valley of large lowland river VII – Lowland rivers 19. Lowland sandy-clayey river 20. Lowland gravely river 24. River in a peat valley 25. River connecting lakes

3 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund MICROSCOPIC EVALUATION - in light microscope with 1000 magnification using immersion objective 100x TAXONOMIC IDENTIFICATION – at least to a species level using standard literature (Krammer & lange-Bertalot ) and other recent monographs COUNTING – diatom valves should be counted in a permanent slifrom a sample RELATIVE ABUNDANCE of i-taxon in a sample: PRETREATMENT AND MICROSCOPIC ANALYSIS L i = Number of valves of taxon i / Number of all valves counted [ ]

4 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund The TI and SI indices are calculated using a weighted formula of Zelinka & Marvan (1961): INDEX = S(L i A i W i )/S(L i W i ) where: L i – relative abundance of i-taxon in a sample (within valves counted ), A i – value of sensitivity (optimum) of i-taxon, W i – value of weight (tolerance) of i-taxon

5 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund The Trophic Index [TI]: Trophic values of indicator taxa: 0.3 – 3.9; Weight values of taxa: 1 – 5 The trophic status of a river according to TI: TITrophic status < 1,0Ultraoligotrophy 1,1-1,3Oligotrophy 1,4-1,5Oligo- mesotrophy 1,6-1,8Mesotrophy 1,9-2,2Meso- eutrophy 2,3-2,6Eutrophy 2,7-3,1Eu- politrophy 3,2-3,4Politrophy > 3,4Poli- hypertrophy

6 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund The Saprobic Index SI: Saprobic values of indicator taxa: 1.0 – 3.8 Weight values: 1 – 5 The saprobic status of a river according to SI: Community consists of taxa:SISaprobic level Sensitive to organic pollution< 1,3Oligosaprobic Weakly tolerant to organic pollution1,4-1,7 Oligo- -mesosaprobic Moderately tolerant to organic pollution1,8-2,1 -mesosaprobic Resistant to organic pollution Saprophiles 2,2-2,5 -meso- -mesosaprobic Resistant to organic pollution Saprobionts 2,6-3,0 -mesosaprobic 3,1-3,4 -meso- polisaprobic > 3,5polisaprobic

7 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund For overall assessment, a module reflecting deviation of species composition in comparison with reference community has been added. The module of reference species [GR]: GR = tR i where: tR i – relative abundance of i-reference taxon The GR values vary between 1 (all species in a sample are of reference character) and 0 (none species is a reference one) Groups of reference species: – for siliceous waters, – for calcareous waters, – for both siliceous and calcareous waters, – type-specific taxa for river groups I–VII

8 Polsko-Norweski Fundusz Badań Naukowych / Polish-Norwegian Research Fund The diatom multimetric index IO is an arithmetic average of three modules: TI, SI and GR. As the TI and SI indices have different ranges, they were transformed according to Schaumburg et al as follows: Z TI = 1–(TI*0.25) Z SI = 1–[(SI-1)*0.33] The values of Z TI and Z SI vary between 1 (the best quality) and 0 (the worst quality) and IO = (Z TI + Z SI + GR)/3 The IO values change from 1 (the best status) to 0 (the worst status).
