• Efficiency of Daphnia magna in removal of green microalgae cultivated in Nordic recirculating aquaculture system wastewater 

  Stevčić, Čedomir; Pulkkinen, Katja; Pirhonen, Juhani (Elsevier, 2020)

  The increase of global aquaculture production has boosted the development of recirculating aquaculture systems not only because they reduce water use but also provide opportunities for waste management and the use of ...

• Interacting effects of simulated eutrophication, temperature increase, and microplastic exposure on Daphnia 

  Hiltunen, Minna; Vehniäinen, Eeva-Riikka; Kukkonen, Jussi V. K. (Elsevier BV, 2021)

  The effects of multiple stressors are difficult to separate in field studies, and their interactions may be hard to predict if studied in isolation. We studied the effects of decreasing food quality (increase in cyanobacteria ...

• The influence of lipid content and taxonomic affiliation on methane and carbon dioxide production from phytoplankton biomass in lake sediment 

  Hiltunen, Minna; Nykänen, Hannu; Syväranta, Jari (John Wiley & Sons, 2021)

  The greenhouse gases methane (CH4) and carbon dioxide (CO2) are end products of microbial anaerobic degradation of organic matter (OM) in lake sediments. Although previous research has shown that phytoplankton lipid content ...

• Screening of microalgae and LED grow light spectra for effective removal of dissolved nutrients from cold-water recirculating aquaculture system (RAS) wastewater 

  Stevčić, Čedomir; Pulkkinen, Katja; Pirhonen, Juhani (Elsevier BV, 2019)

  Popularity of recirculating aquaculture systems (RAS) is increasing. Because of the high water recirculation rate, dissolved nutrients originating from fish feed are concentrated enough in RAS wastewater (WW) to enable ...

• Whole-Lake Sugar Addition Demonstrates Trophic Transfer of Dissolved Organic Carbon to Top Consumers 

  Jones, Roger; Kankaala, Paula; Nykänen, Hannu; Peura, Sari; Rask, Martti; Vesala, Sami (Springer New York LLC, 2018)

  Terrestrial dissolved organic carbon (DOC) provides an external carbon source to lake ecosystems. However, there is ongoing debate about whether external DOC that enters a lake can pass up the food web to support top ...
