ARE HABITATS WITH Campanula romanica Savul. PREFERRED BY THE SOIL FAUNA?

In 2021, from the first time in Romania, soil fauna taxa were investigated from two types of habitats: with and without Campanula romanica, from Macin Mountains National Park. Some population parameters were analysed as: taxa diversity, numerical abundance, dominance, evenness, equitability, Shannon-Wiener index of diversity. In total, 24 soil fauna groups were identified, with 399 individuals, recording characteristic structure and taxa for each type of plots. Even if the number of identified taxa is almost similar between plots, the numerical abundance was higher in areas without Campanula romanica. In the same time sixteen environmental variables were quantified, as: the thickness of three soil layers, air temperature and humidity, soil temperature and moisture, soil pH, soil penetration resistance, amount of organic carbon, total nitrogen, C/Nt ratio, humus content, potassium content, phosphorous content and the vegetation cover. They had a significant influence on structure composition of the edaphic taxonomic groups from the two types of habitats.
