    Diagnosing of Biological Productivity in Lake Ecosystems by Viktor V. Boulion

    Published 2019-05-01
    “…Input parameters of system (x – variables) are latitude, specific catchment area, average annual air temperature, annual sum precipitation, mean and maximum water body depth, water retention time in lake, average for growing season water color and daily assimilation number for phytoplankton chlorophyll. Under the conditions of lack of data on the water bodies’ environmental status, the diagnostic system is often combined with modelling that enables to reconstruct the most important biological/production characteristics of water bodies. …”

    Bioaccumulation of microcystins in invasive bivalves: A case study from the boreal lagoon ecosystem by Aistė Paldavičienė, Anastasija Zaiko, Hanna Mazur-Marzec, Artūras Razinkovas-Baziukas

    Published 2015-01-01
    “…However, certain amount of microcystin was recorded in mussel tissues in 2007 and 2008, when no cyanotoxins were reported in the phytoplankton. Considering high depuration rates and presence of cyanotoxins in the bottom sediments well after the recorded toxic blooms, we assume mechanism of secondary contamination when microcystin residuals could be uptaken by mussels with resuspended sediment particles.…”
