FEATURES OF DISTRIBUTION OF RARE EARTH ELEMENTS IN THE WATERS AND BOTTOM SEDIMENTS OF SMALL LAKES OF THE BARABINSK LOWLAND AND THE KULUNDINSKY PLAIN by Vera D. Strakhovenko, Ekaterina A. Ovdina

“…The application of a unique methodological approach, expressed in modern biogeochemical, mineralogical, geochemical studies of a single lake in close relationship with the entire system of compactly located lakes (lake system) on the carefully selected lake systems: Barabinskaya, Kuibyshevskaya (Baraba) and Tanatarskaya, Petukhovskaya (Kulunda), gave an idea of the relationship of the modern formation of the composition of bottom sediments with the biogeochemistry of lake waters, with the composition of soils and soil-forming rocks of the catchment areas of the lake, the chemical composition of the autochthonous biota and the landscape conditions. …”

Molecular physiology of Antarctic diatom natural assemblages and bloom event reveal insights into strategies contributing to their ecological success by Carly M. Moreno, Margaret Bernish, Meredith G. Meyer, Zuchuan Li, Nicole Waite, Natalie R. Cohen, Oscar Schofield, Adrian Marchetti

“…Rapid environmental changes coincide with shifts in plankton community composition and productivity, food web dynamics, and biogeochemistry. Despite the progress in identifying important environmental factors influencing plankton community composition in the WAP, the molecular basis for their survival in this oceanic region, as well as variations in species abundance, metabolism, and distribution, remains largely unresolved. …”
