Lake restoration influences nutritional quality of algae and consequently Daphnia biomass
Taipale, Sami J.; Kuoppamäki, K.; Strandberg, U.; Peltomaa, E.; Vuorio, K. (Springer, 2020)Food quality is one of the key factors influencing zooplankton population dynamics. Eutrophication drives phytoplankton communities toward the dominance of cyanobacteria, which means a decrease in the availability of sterols ... -
Eutrophication and browning influence Daphnia nutritional ecology
Taipale, Sami J.; Aalto, Sanni L.; Galloway, Aaron W. E.; Kuoppamäki, Kirsi; Nzobeuh, Polain; Peltomaa, Elina (Taylor & Francis, 2019)Climate change and land-use practices can enhance lake eutrophication and browning, which influence phytoplankton composition by decreasing the availability of food high in nutritional quality (algae) and increasing the ... -
The Importance of Phytoplankton Biomolecule Availability for Secondary Production
Peltomaa, Elina T.; Aalto, Sanni L.; Vuorio, Kristiina M.; Taipale, Sami (Frontiers Media S.A., 2017)The growth and reproduction of animals is affected by their access to resources. In aquatic ecosystems, the availability of essential biomolecules for filter-feeding zooplankton depends greatly on phytoplankton. Here, we ... -
Poor nutritional quality of primary producers and zooplankton driven by eutrophication is mitigated at upper trophic levels
Taipale, Sami Johan; Ventelä, Anne‐Mari; Litmanen, Jaakko; Anttila, Lauri (John Wiley & Sons, 2022)Eutrophication and rising water temperature in freshwaters may increase the total production of a lake while simultaneously reducing the nutritional quality of food web components. We evaluated how cyanobacteria blooms, ... -
Increasing concentration of polyunsaturated fatty acids in browning boreal lakes is driven by nuisance alga Gonyostomum
Strandberg, Ursula; Hiltunen, Minna; Rissanen, Ninni; Taipale, Sami; Akkanen, Jarkko; Kankaala, Paula (Ecological Society of America, 2020)Elevated concentrations of dissolved organic carbon (DOC) promote browning of lakes, which alters the physicochemical properties of water and ecosystem functioning. However, browning‐induced changes in basal production of ...
