Sediment nitrogen transformations during an ice-free winter in a large, shallow, eutrophic lake
(Estonian University of Life Sciences, 2022)Objectives: 1. Characterize and quantify water column nitrogen (N) cycling rates in lakes Peipsi and Võrtsjärv (Estonia) a. Ammonium (NH4+) uptake and regeneration b. Nitrification 2. Characterize and quantify ... -
Three years into studying N cycling in lakes Peipsi and Võrtsjärv - where we stand, and what’s next : [presentation]
(Estonian University of Life Sciences, 2021)Objectives: 1. Characterize and quantify water column nitrogen (N) cycling rates in lakes Peipsi and Võrtsjärv a. Ammonium (NH 4 ++) uptake and regeneration b. Nitrification 2. Characterize and quantify sediment water ... -
Generalist invasion in a complex lake food web
(Wiley, 2023)Invasive species constitute a threat not only to native populations but also to the structure and functioning of entire food webs. Despite being considered as a global problem, only a small number of studies have quantitatively ... -
Strong temporal variation of consumer δ13C value in an oligotrophic reservoir is related to water level fluctuation
(Nature Portfolio, 2023)Using stable carbon and nitrogen isotope analysis (δ 13 C and δ 15 N) to assess trophic interactions in freshwater ecosystems is a well established method, providing insight into ecosystem functioning. However, the spatial ... -
Changes in nutrient concentration and water level affect the microbial loop: a multi-seasonal mesocosm experiment
(Springer, 2023)Eutrophication and lake depth are of key importance in structuring lake ecosystems. To elucidate the effect of contrasting nutrient concentrations and water levels on the microbial community, we manipulated water depth and ... -

(Eesti Maaülikool, 2023)Esitlus "Euroopa Horisondi“ uute taotlusvoorude infopäeval Eesti Maaülikoolis, 11.01.2023 -
Predicting multiple stressor effect on zooplankton abundance, biomass and community composition in two large eutrophic lakes : [presentation]
(Estonian University of Life Sciences, 2022)Presentation at the BIOGEOMON 2022, 10th International Symposium on Ecosystem Behavior, June 26–30, 2022, Tartu, Estonia. -
Effects of multiple stressors on nitrate and cyanobacteria in a large shallow lake : [presentation]
(Estonian University of Life Sciences, 2022)Presentation at the 36th Congress of the International Society of Limnology, 7-10 August 2022, Berlin. -
Internal nitrogen loading in eutrophic lakes : moving beyond nutrient concentration measurements and Liebig’s Law : [presentation]
(Estonian University of Life Sciences, 2022)The paradigm: Freshwater systems are phosphorus limited because nitrogen deficiencies are corrected by nitrogen fixation. -
Lipid-normalizing δ²H values from aquatic organisms : [presentation]
(University of Jyväskylä, 2022)As lipids are isotopically lighter than other tissues, routing of lipids directly from dietary items is expected to have a significant impact on bulk tissue-diet hydrogen isotope relations, as is well established for carbon. -
Võrtsjärv on võrratu! : [esitlus]

Towards Research Excellence and Innovation Capacity in Studing Lake Ecosystems Functional Structures and Climate Change Impact – TREICLAKE : [presentation]
(Estonian University of Life Sciences, 2022)Objectives: to improve/icrease in EMU Chair of hydrobiology and fisheries 1. Scientific Expertise 2. Scientific Infrastructure (mesocosm facility) 3. Impact in the Scientific Community 4. Management and administration ... -
What is the use of lake science in the management and maintenance of lakes? : [presentation]
(Estonian University of Life Sciences, 2022)EU Horizon 2020 Project „Towards Research Excellence and Innovation Capacity in Studying Lake Ecosystems’ Functional Structures and Climate Change Impact“ – TREICLAKE – aims to increase the scientific expertise of Estonian ... -
Behavioural responses of invasive (Gmelinoides fasciatus) and native (Gammarus lacustris) amphipods to predators on different bottom substrates
(Springer, 2023)The amphipod Gmelinoides fasciatus has invaded and established in numerous large lakes in Eurasia and, in the process, has displaced the native amphipod, Gammarus lacustris. The mechanism behind its invasion success ... -
Bimodality and alternative equilibria do not help explain long-term patterns in shallow lake chlorophyll-a
(Springer Nature, 2023)Since its inception, the theory of alternative equilibria in shallow lakes has evolved and been applied to an ever wider range of ecological and socioecological systems. The theory posits the existence of two alternative ... -
Effects of filtration timing and pore size on measured nutrient concentrations in environmental water samples
(Wiley, 2022)Nutrient monitoring is important for informing management decisions to mitigate eutrophication in aquaticsystems. Many nutrient monitoring programs usefilter pore sizes that allow microorganisms to pass into sam-ples and/or ... -
The comparison of the feeding of European perch Perca fluviatilis L. larvae in littoral and pelagic habitats of northern temperate lakes
(Estonian Academy Publishers, 2022)We studied the feeding of European perch Perca fluviatilis L. larvae in littoral and pelagic habitats of four different lakes – one Latvian (Auciema) and three Estonian (Akste, Kaiavere, and Prossa). Altogether, 162 perch ... -
Effects of environmentally relevant concentrations of microplastics on amphipods
(Elsevier, 2022)Lack of microplastics (MP) toxicity studies involving environmentally relevant concentrations and exposure times is concerning. Here we analyzed the potential adverse effects of low density polyethylene (LDPE) MP ... -
Opportunities for combining data of Estonian and Russian monitoring to reflect on water quality in large transboundary Lake Peipsi
(Elsevier, 2022)Lake Peipsi, one of the world’s largest lakes, is shared between Estonia and Russia. The water quality in different parts of the lake has so far been assessed independently. Here we explore opportunities for combining ... -
Summer greenhouse gas fluxes in different types of hemiboreal lakes
(Elsevier, 2022)Lakes are considered important regulators of atmospheric greenhouse gases (GHG). We estimated late summer open water GHG fluxes in nine hemiboreal lakes in Estonia classified under different lake types according to ...
