project VEGA 1/0315/23 (2023-2026) - The role of bioindicators in recognising anthropogenically induced changes in the water-air regime of soils under different land use. The research of this ongoing project aims to understand the role of selected groups of soil organisms in identifying processes that lead to the degradation of soil cover in variously managed soils. It focuses mainly on studying the relationship between biological and functional physical properties of soil. Looking at soil structure is necessary to understand the effects of natural and anthropogenic environmental changes. Soil structural heterogeneity is crucial in the coexistence of several functional groups of soil organisms that live in it permanently or temporarily. Therefore, emphasis will be placed on determining changes in the characteristics and physiological manifestations of functional groups of organisms in soils with different types of management, especially on the factors that caused these changes. The project's output will be knowledge of how selected groups of soil organisms can be potentially used as bioindicators of soil health.

project VEGA 1/0194/21 (2021 - 2024): Ecological assessment of revitalized acidified area (investigator)

The landscape in the Banská Štiavnica surroundings has been marked by intense mining activity (MA) in the past, which is reflected in specific conditions for living organisms. Besides visual changes in the landscape, MA have led to changes in the quality of abiotic components of the environment (soil, water), which form the

conditions for the biotic components. One of the negative impacts of MA in the area is the acidification of the environment. Increased acidification is associated with the mobility of toxic elements causing contamination of the area, which results in the land degradation and the extinction of habitats and ecol. relationships. One of the measures to improve the quality of the environment is the application of revitalization measures. The research challenge is therefore to evaluate and interpret data on the soil microbiota, to determine selected ecological parameters and to interpret what changes in the environment occurred after the application of revitalization measures in the study area.

project VEGA 1/0424/18 (2018 - 2020): Autochthonous microbiota of soils in extreme conditions of blackfields and brownfields (investigator)

The most frequent sources of negat. anthrop. influences of the environ. in Slovakia include old mining and processing areas and contaminated and qualitatively disadvantaged areas such as anthrop. salty soils. Such localities include environ. burdens and some of them represent blackfields (BlF) or brownlields (BrF) and can represent sources of potentially toxic elements, they can be extremely acidic or strongly alkaline with higher concentrations of salts. Autochthonous microbiota (AM) of these substrates is often a source of novel species of microorganisms (MO), which have been adapted to these conditions on the microscopic and also very often on the genetic level. The aim of the project is to identify the AM representatives in selected BrF and BlF using biochem. and molecular methods (next-generation sequencing), to determine their physiol. properties and to create a geodatabase of these AM representatives with the particular attributes as a basis for identification of spatial distribution of MO.

project VEGA 1/0482/15 (2015 - 2017) Spatial distribution distribution of indigenous microflora of old environmental burdens and its use in bioleaching of potentially toxic elements (investigator)

Old environmental burdens often represent such sites, where all mining activities are finished with remaining settling plants or piles and their negative impact on surrounding environment is obvious. In settling plants and piles, weathering of material, solubilisation and oxidation of ore-bearing rocks containing various potentially toxic elements (As, Pb, Ni, Cd, Hg) are carried out followed by soil, water and sediments contamination. Autochthonous bacteria and microscopic fungi are capable of adapt to negative ecological factors of old environmental burdens and leach the potentially toxic elements from substrates. The aim of the project is to record the spatial variability of autochthonous microflora, determine physiological properties of autochthonous microorganisms with growth conditions, tolerance and adaptability including analysis of physiological properties of bioleaching of metal(loid)s.
