“…Desert ecosystem biodiversity monitoring provides insight and comprehensive data on habitat conditions, vegetation, and plant community composition; in the extreme desert ecosystem, the biodiversity recordings enable the analysis of the relationships between plant diversity taxonomic, functional, soil properties, and Rs along a severe environmental gradient. The study of the functioning of ecosystems existing in extreme environments, e.g., post-mining sites, and desert ecosystems can enhance the understanding of the mechanisms by which Rs responds to relevant drivers, and may be helpful to the understanding and management of future climate change (Wang et al, 2022).…”

The subject of the paper is the analysis of the relationship between spontaneous vegetation diversity and soil respiration in novel post-coal mine ecosystem. In the natural and semi-natural ecosystems, soil respiration process (Rs) is a crucial ecosystem function regulating terrestrial ecosystems’ carbon cycle. Soil respiration depends on the quality and quantity of the soil organic matter (SOM), the soil microbes’ activity, and root metabolism. The listed factors are directly related to the composition diversity of vegetation plant species (biochemistry). For many years, soil respiration parameters have been studied in natural and seminatural vegetation communities and ecosystems. However, there still need to be a greater understanding of the relationship between vegetation plant species diversity and soil respiration as a crucial ecosystem function. Plant species diversity has to be analysed through both the taxonomic diversity and the functional diversity. These approaches reflect the composition, structure, and function of plant species communities. We hypothesise that the diversity of the spontaneous vegetation species composition shapes the amount of soil respiration in a post-coal mine novel ecosystem. The soil respiration differs significantly along the vegetational types driven by habitat gradients and is significantly higher in highly functional richness and dispersion vegetation patches. Contrary to our expectation, soil respiration was the highest in the less diverse vegetation types – both taxonomical and functional evenness were non-significant factors. Only functional dispersion is weakly negative correlated with soil respiration level (SRL).
