  • Atmospheric stilling offsets the benefits from reduced nutrient loading in a large shallow lake 

    Janatian, Nasime; Olli, Kalle; Cremona, Fabien; Laas, Alo; Nõges, Peeter (Wiley, 2019)
    As part of a global phenomenon, a 30% decrease in average wind speed since 1996 in southern Estonia together with more frequent easterly winds resulted in 47% decrease in bottom shear stress in the large (270 km2), shallow ...
  • Effect of crop residue decomposition on soil aggregate stability 

    Stegarescu, Gheorghe; Escuer-Gatius, Jordi; Soosaar, Kaido; Kauer, Karin; Tõnutare, Tõnu; Astover, Alar; Reintam, Endla (MDPI, 2020)
    The decomposition of fresh crop residues added to soil for agricultural purposes is complex. This is due to di erent factors that influence the decomposition process. In field conditions, the incorporation of crop residues ...
  • The interaction of soil aggregate stability with other soil properties as influenced by manure and nitrogen fertilization 

    Are, Mihkel; Kaart, Tanel; Selge, Are; Astover, Alar; Reintam, Endla (Lithuanian Research Centre for Agriculture and Forestry, Vytautas Magnus University, 2018)
    Soil water-stable aggregate (WSA) stability is one of the most important indicators of soil health, because it influences chemical, biological and other physical properties. At the same time, WSA formation, stabilization and ...
  • Otsekülvi mõju mulla kvaliteedile Eesti tootmispõldudel 

    Reintam, Endla; Sutri, Merit; Kahu, Greete; Are, Mihkel; Stagerescu, Gheorge; Selge, Are (Eesti Maaülikool; Eesti Taimekasvatuse Instituut, 2018)
    Finding out the best agricultural management practices for certain climatic regions and soils is crucial to maintain soils quality. One of the practices, to stop soil erosion, reduce leaching and increase soil organic ...
  • Phytoplankton responses to meteorological and hydrological forcing at decadal to seasonal time scales 

    Janatian, Nasime; Olli, Kalle; Nõges, Peeter (Springer Nature, 2021)
    One of the challenges for predicting global change effects on aquatic ecosystems is the vague understanding of the mechanisms of multiple controlling factors affecting phytoplankton dynamics at different time scales. ...
  • Post-soviet changes in nitrogen and phosphorus stoichiometry in two large non-stratified lakes and the impact on phytoplankton 

    Nõges, Tiina; Janatian, Nasime; Laugaste, Reet; Nõges, Peeter (Elsevier, 2020)
    The post-soviet period in Eastern Europe brought about fast changes in economy, land use, and environmental protection, whereas legacy effects of the previous era of heavy contamination continued emerging in the status of ...
  • Storm impacts on phytoplankton community dynamics in lakes 

    Stockwell, Jason D.; Doubek, Jonathan P.; Adrian, Rita; Anneville, Orlane; Carey, Cayelan C.; Carvalho, Laurence; De Senerpont Domis, Lisette N.; Dur, Gaël; Frassl, Marieke A.; Grossart, Hans-Peter; Ibelings, Bas W.; Lajeunesse, Marc J.; Lewandowska, Aleksandra M.; Llames, María E.; Matsuzaki, Shin-Ichiro S.; Nodine, Emily R.; Nõges, Peeter; Patil, Vijay P.; Pomati, Francesco; Rinke, Karsten; Rudstam, Lars G.; Rusak, James A.; Salmaso, Nico; Seltmann, Christian T.; Straile, Dietmar; Thackeray, Stephen J.; Thiery, Wim; Urrutia-Cordero, Pablo; Venail, Patrick; Verburg, Piet; Woolway, R. Iestyn; Zohary, Tamar; Andersen, Mikkel R.; Bhattacharya, Ruchi; Hejzlar, Josef; Janatian, Nasime; Kpodonu, Alfred T. N. K.; Williamson, Tanner J.; Wilson, Harriet L. (Wiley, 2020)
    In many regions across the globe, extreme weather events such as storms have increased in frequency, intensity, and duration due to climate change. Ecological theory predicts that such extreme events should have large ...
  • Water satability of soil aggregates in a 50-year-old soil formation experiment on calcareous glacial till 

    Are, Mihkel; Kauer, Karin; Kaart, Tanel; Selge, Are; Astover, Alar; Reintam, Endla (Pleiades Publishing, Ltd., 2020)
    Soil formation on the human time scale is immensely time consuming, although it can be significantly accelerated through the effects of vegetation. The content of water-stable aggregates (WSAs) is a useful indicator for ...
