“…Toxic elements actively affect reproduction and metabolic activities of plankton organisms representing the bottom levels of a food chain (Marine report 2009;Luk'yanenko & Cherkashin 1987;Finenko et al 2003;Tokarev & Shulman 2007). Accumulation of heavy metals in organisms of different taxonomic groups, as well as behavioral responses of hydrobionts to the presence of heavy metal ions, have been quite well investigated (Vasil'kov 2005;Klishko et al 2007;Mosharov et al 2009). Years of field and experimental research showed that toxic heavy metals, such as cadmium, lead, mercury, copper and zinc are among the most significant pollution actors in marine environments and should be a priority for further investigation (Vasil'kov 2005;Nikitina et al 2009;Rudneva 1995).…”

Investigations were conducted in the Department of biophysical ecology of Kovalevsky IMBR of RAS in September - October of 2013 and 2015. The body length of the gathered for experiments ctenophores was 35 – 40 mm. Characteristics of the ctenophores light emission were studied under the mechanical and chemical stimulations, with the usage of laboratory complex “Svet”. The following HM salts: Cu2S04, ZnCl2, PbCl2 and HgCl2 in different concentrations were used in our experiments. The just-caught samples, contained in the clean marine water were used as a control. The exposition time was 1, 3 and 24 hours under the temperature of 21 ± 2°C. The investigations results have shown considerable variability of the ctenophore luminosity characteristics in dependence of metal concentration and exposition duration. It was stated that minimal concentrations of cooper, zinc and mercury stimulates ctenophores bioluminescence and the high ones inhibit. The alien ctenophore luminescence inhibition was registered under the lead activity under all investigated concentrations. We can place investigated metals as following: Zn < Cu < Hg < Pb, according to the force of the toxic influence on the ctenophore bioluminescence. Thus, alien ctenophore bioluminescence parameters can serve as a sensitive express-indicator of the resistance degree to the heavy metals impact and be the expressive index of the marine environment regional pollution.

“…The indicative capabilities of slow-moving bottom invertebrates can be used to effectively pinpoint contamination sources, since the chemical composition and accumulation of toxic elements in certain biological objects provide information on contaminated localities for a short period. Such findings, when compared with current data on the background concentrations of heavy metals in natural and natural-technogenic water bodies across a wide environmental gradient, can contribute to water quality assessment and provide solutions for the degradation of water ecosystems within different geochemical provinces [13].…”

Water has a profound influence on the evolution of the biosphere and can be regarded as a thermodynamic parameter. The priorities and objectives in this research include determining the hydrological features of rivers and lakes in the region as indicators of the thermodynamic activity of water in the evolutionary processes; hydrology and ecology of the cryptobiosphere; the effects of water on the evolutionary adaptations and strategies in living organisms in biogeochemical systems of different origins; and the hydrology of possible alternative stable states of biogeochemical systems.
