Diet and trophic niche of the invasive signal crayfish in the first invaded Italian stream ecosystem
(Nature, 2021)The occurrence of the signal crayfsh Pacifastacus leniusculus in the Valla Stream was the frst established population of this invasive species recorded in an Italian stream ecosystem. We evaluated the seasonality of diet ... -
6 põhjust, miks Peipsi järv vajab tähelepanu : [faktileht]
(Eesti Maaülikool, 2021)Peipsi järv on Euroopa üks kalarikkam ja suurim piiriülene järv. Õigupoolest koosneb järv kolmest osast: Peipsi, Pihkva ja Lämmijärvest. Kuna jagame järve Venemaaga, siis keskkonnakaitse meetmeid tuleb ellu viia ... -
From microscopy to genes – tracing toxic cyanobacteria in a shallow eutrophic lake
(Estonian University of Life Sciences, 2022)Global warming paired with eutrophication processes is shifting phytoplankton communities towards the dominance of bloom-forming and potentially toxic cyanobacteria. Cyanobacterial blooms are considered an increasing threat ... -
Phytoplankton as ecological quality indicator of lakes
(Estonian University of Life Sciences, 2021)According to Water Framework Directive (WFD), phytoplankton abundance, composition and bloom metrics should be used in lake ecological quality assessment. Phytoplankton is highly sensitive to environmental changes and can ... -
Hydrometeorological and climatic control over lake phytoplankton : the importance of time scales
(Estonian University of Life Sciences, 2021)Phytoplankton reflects changes in the environment and plays a vital role in biogeochemical cycles and the climate system. The thesis attempts to link the phytoplankton dynamics with the timing, intensity, and duration of ... -
Impact of climate change and other ecological factors on selected fish populations and fishery in Estonian large lakes
(Estonian University of Life Sciences, 2021)Human activities and climate change have become the most consequential threats to freshwater ecosystems and their inhabitants, especially fish. The response of the fish population to their environment is not always ... -
The impact of climate change and eutrophication on phosphorus forms in sediment: Results from a long-term lake mesocosm experiment
(Elsevier, 2022)Characteristics of bottom sediments in lake mesocosms 11 years after starting the experiment were studied in order to determine the effects of nutrient loading, temperature increase and vegetation type on concentration ... -
Nitrate as a predictor of cyanobacteria biomass in eutrophic lakes in a climate change context
(Elsevier, 2022)We aimed to predict cyanobacteria biomass and nitrate (NO₃) concentrations in Lake Võrtsjärv, a large, shallow, and eutrophic lake in Estonia. We used a model chain based on the succession of a mechanistic (INCA-N) ... -
Causal networks of phytoplankton diversity and biomass are modulated by environmental context
(Nature Research, 2022)Untangling causal links and feedbacks among biodiversity, ecosystem functioning, and environmental factors is challenging due to their complex and context-dependent interactions (e.g., a nutrient-dependent relationship ... -
Catchment soil characteristics predict organic carbon, nitrogen, and phosphorus levels in temperate lakes
(The University of Chicago Press, 2021)Allochthonous supply of dissolved organic matter (DOM) and nutrients from the catchment have a sub- stantial impact on the physical and chemical properties of lake water. Transport of DOM and nutrients is affected by ... -
Sediment phosphorus mobility in Võrtsjärv, a large shallow lake: Insights from phosphorus sorption experiments and long-term monitoring
(Elsevier, 2022)Sediment phosphorus (P) recycling is one of the key issues in lake water quality management. We studied sediment P mobility in Võrtsjärv, a large shallow lake in Estonia using both sorption experiments and long-term ...
