Estimation of periphytic microalgae gross primary production with DCMU-fluorescence method in Yenisei River (Siberia, Russia) / V. I. Kolmakov [et al.] // Journal of Applied Phycology. - 2008. - Vol. 20, Is. 3. - P289-297, DOI 10.1007/s10811-007-9246-8 . - ISSN 0921-8971

Chlorophyll fluorescence -- Gross primary production -- Periphytic microalgae
Аннотация: Periphyton (epilithon) gross primary production (GPP) was estimated using the DCMU-fluorescence method in the Yenisei River. In the unshaded littoral zone, chlorophyll a concentration (Chl a) and GPP value varied from 0.83 to 973.74 mg m-2and 2-304,425 O2 m-2 day -1 (0.64-95 133 mg C m-2 day-1), respectively. Positive significant correlation (r=0.8) between daily GPP and periphyton Chl a was found. Average ratio GPP:Chl a for periphyton was 36.36 mg C mg Chl a m -2 day-1. The obtained GPP values for the Yenisei River have a high significant correlation with values predicted by a conventional empirical model for stream periphyton. We concluded that the DCMU-fluorescence method can be successfully used for measuring of gross primary production of stream phytoperiphyton at least as another useful tool for such studies.

Аннотация: Productivity characteristics of phytoplankton, phytoperiphyton, and five species of macrophytes in the mountain oligotrophic Lake Oiskoe (Ergaky Mountain Range, West Sayan) have been studied. High primary productivity has been noted for phytoperiphyton and macrophyte communities. Photosynthetic parameters of the macrophyte leaves have been compared using a PAM fluorimeter.

Phytoplankton and Phytoperiphyton Characteristics of Lake Pyasino and Its Tributaries after an Accidental Fuel Spill in 2020 / E. S. Kravchuk, A. V. Kotovshchikov, E. A. Ivanova // Contemp. Probl.

fuel pollution -- freshwater ecosystems -- phytoplankton -- phytoperiphyton -- photosynthetic pigments -- Lake Pyasino -- Ambarnaya River
Аннотация: An assessment of the species composition, abundance, biomass, and pigment characteristics of phytoperiphyton and phytoplankton of Lake Pyasino, its tributaries (Bezymyannyi Stream, Daldykan, Ambarnaya, and Norilskaya rivers), and the head of the Pyasina River has been carried out after a manmade accident (a diesel-fuel spill near the city of Norilsk in May 2020). A significant decline in the biomass and changes in the species composition of phytoperiphyton after the water was contaminated by fuel is revealed only near the spillage site (in the Daldykan River and the Ambarnaya River downstream the mouth of the Daldykan). Downstream, in the Ambarnaya mouth zone, as a response to the release of a large amount of nutrients during the decomposition of fuel products and dead organisms, as well as the mechanical cleaning of the bank line, there has been a massive growth of diatom and green algae (Tabularia tabulata, Spirogyra sp.) in the water column and the appearance of indicators of organic pollution (Euglenophyceae and Cryptophyceae). No significant changes in the plankton of Lake Pyasino and the Pyasina River in comparison with the data obtained in the second half of the 20th century (i.e., long before the accident) are found. Species composition and quantitative features, as well as amount and ratio of pigments, characterized the phytoplankton and phytoperiphyton of Lake Pyasino and the Pyasina River as a normally functioning freshwater community of oligotrophic waters. All this indicates the absence of a negative impact of the accidental fuel spill on the ecosystem of Lake Pyasino and the Pyasina River.
