Correlation adaptometry of microelement composition of tissues as a method of estimation of the environmental stress (on the example of populations of commercial fishes from mineralized water)

Abstract

Correlation adaptometry (CA) - is a branch of Russian biology, medicine and bioinformatics. It studies the link formation in biological systems and their change under different extreme and stress factors. The theory and practice of CA states, that with the increase of adaptive costs of population in response to stressful influence, the weight of the correlation graph (WCG) rises. WCG is the summary of all the absolute values of the correlation coefficients. Using the Spearman’s correlation method 7 heavy metals (Mn, Fe, Co, Ni, Cu, Zn, Cd) in the muscle and bone tissue of the roach Rutilus rutilus (L., 1758) and perch Perca fluviatilis (L., 1758) from the two Ural lakes, containing different amount of mineralization, were analyzed and the amount of WCG was evaluated. The results were compared using the four-way ANOVA on pseudovalues of the jackknife. It was proven that in the water with high mineral content (TDS=4,57 g/l) the WCG was much, than in the fresh lake (TDS=0,48 g/l): F_(1/36)=13,0; Р=0,001. The conclusion is made that the data on microelemental contents of the organisms can be used in the CA methodology to gauge the levels of adaptive costs to sustain homeostasis and to estimate the levels of stress impact in ecological and veterinary research.
