The zooecological remediation of technogen faulted soil in industrial region of Ukraine steppe zone
111-115Views:87In Ukraine’s Steppe zone the extraction of minerals is important. To eliminate the consequences of coal mining the agricultural recultivation of the disturbed soil is used. Thus toxic compounds for human beings and the majority of plants and soil biota representatives, which can be found mining rock, get into plants and invertebrates by trophy chains. When remediating soil, it is necessary to create tropic conditions in order to provide the life of soil biota. Earthworms (Lumbricidae) are the primary decomposers of the organic material. They are numerous in soil and facilitate the improvement of natural and artificially created soil. This paper studies the possible influence of different variants of substrates, which are used in re-cultivation, the leaf litter from leaves of different wood species, as well as different levels of humidity on the representatives of soil saprophages. Optimal variants of artificial mixed-soil providing the stable existence of animals have been shown, which are recommended for the implementation of rehabilitation measures.

Influence of mammal fossorial activity on bearing-out some chemical elements on up of soil cover
117-120Views:97Fossorial activity of mammals is conductive to trace of microelements from more deep soil horizons into zone of its active involving to biological cycle. As a result of researches have established the mostly intensive migration of micro- and macroelements that is goes at the expense of mammals fossorial activity it is typical for humid gully lime-and-ash with oak wood. A middle position in speed of entering chemical elements is belonging to artificial oak wood in the watershed and humid lime-and-ash with oak wood in floodplain. Mostly slow migration in speed of entering elements is typical for middle-dry pine wood on sandy terrace.

Influence of phytophagous mammals environment-forming activity on the soil invertase fermentative activity in conditions of mining impact region
127-130Views:111Excretorial and fossorial activity of mammals is an important part of environment-forming activity. Mammals have influences on important biogeocenotic processes, especially on the soil processes. Determination the maintenance of soil invertase as one of diagnostic description the ecological state allowed defining limits of oscillation index in dump areas and in clean (control) native areas. The obtained results of the investigation indicate the soil depth, duration of experiment and type of area influence on soil invertase activity with the high statistical level of significance. Positive influence is revealed on invertase activity changing on dump areas, where an active excretorial and fossorial activity of phytophagous mammals was observed.
