Biogeochemical characteristics of dominant gastropod species from the stony littoral of southern Baikal

Large-Field Electron Imaging and X-ray Elemental Mapping Unveil the Morphology, Structure, and Fractal Features of a Cretaceous Fossil at the Centimeter Scale

“…In the case of gastropods, the organisms accumulate a large quantity of Zn during their lives, allowing this chemical element to be available in the environment after their deaths to form compounds such as ZnS. Regarding the shrimp A1, the presence of Zn can also be attributed to an accumulation process during life, although it is known through modern toxicological studies that shrimps are not an efficient trap for Zn , as are gastropods, ,− and are able to regulate their total body levels of Zn . Obviously, we cannot exclude a different origin for Zn, such as its introduction by water with a high concentration of zinc.…”

Coastal zone of the world’s great lakes as a target field for interdisciplinary research and ecosystem monitoring: Lake Baikal (East Siberia)

“…Second, they are able to synthesize and extract a wide spectrum of macro-and microelements, organic compounds (including environmentally aggressive organic acids), which literally destroy the minerals of the stony bottom and perform significant vital element contribution to the ecosystem. At least three indirect data sets support this conclusion: 1) significant abundance and huge biomass of sponges 6 simply cannot be determined by nutrients (especially -of silica, for example) taken from the water column only; 2) the same is true with regard to the elemental composition of the dominant groups of hydrobionts (Kulikova et al, 2007;2008a;2008b;2009b;2013;2018); 3) selectiveness of biofilms, algae and invertebrates to the petrographic composition of the rocks on stony bottoms of the coastal zone (Timoshkin, 2001(Timoshkin, -2011Suturin et al, 2005;Timoshkin et al, 2005;Parfenova et al, 2008).…”
