A comparative study has been conducted on the ecological and biological parameters of the soil at the Rostov-on-Don Zoo. The objects of the research were the parts of the zoo with various conditions: the cages with different animals (hyenas, emus, cranes, peacocks and other birds, zebras, deer, camels and mountain sheep). Moreover, the influence of the recreational impact, caused by the visitors of the park, on the soil landscape has also been examined. The control part of the zoo for drawing the comparison was th...

A comparative study of the influence of the multiyear application of the No-Till technology on enzymatic activity of different chernozems of two districts in the Rostov region was carried out. These soils are widespread in the vast territories of southern Russia and are the most productive arable soils. As a result, in different climatic conditions and on different subtypes of chernozems it has been established that long-term application of No-Till of direct sowing with the accumulation of plant residues on the so...

The examples of modern biophysical and biochemical methods used at the Black Sea coastal zone biotesting were presented. Their obvious advantages in precision, objectivity and efficiency of received information in comparison with other methods were shown. The bioluminescence analysis as biophysical method was used. The obtained results revealed trustworthy relation between bioluminescence field variability and ecological conditions of studied coastal areas. Ambiguous influence of heavy metals on bioluminescence of...

The estuarine region of the Don River is a unique area occupied by a complex natural-technogenic system of interacting natural, urbanized, and agrarian ecosystems. The aim of this work was to study the level and degree of mobility of heavy metals (HMs) in the soil-plant system and to perform bioindication observations in the Don River estuarine region and the Russian sector of the Taganrog Bay coast. The soil cover is represented by following soils types: Fluvisols, Haplic Chernozem, Arenosol, Solonchak. The follo...
