The aim of this study is to provide data on biological state of soil in depth, using the comparative study of general microbiota frequency and activity. For the quantitative analysis of soil microbiota, we have used soil samples for dilutions (10-1 - 10-6). The results were expressed in colony-forming units/g soil (CFU). The soil was sampling from Calimani National Park (The Oriental Carpathians) in October 2006, June and September 2007. The soil microbiota registers quantitative variations from one sample point t...

Wetlands are important habitats consisting in true biodiversity pools. Human pressure had a continuous negative impact during time, i.e. significant changes, or more, irreversible, where the area of oligothrophic bogs has been reduced. Our observations have been carried in Tinovul Mare–Poiana Stampei Natural Reserve, situated in Dorna Depression (The Oriental Carpathians) at 910 m altitude, with 677 ha. This is the largest peat bog in Romania. The main goal is focused on all biotic and abiotic factors which are in...

Our investigation regard the distribution of pollutant in the soils degraded by mine activity in the circuit soil-macromycetes. Pollutants categories have been evidenced using FT-IR spectroscopy. Our results underline the macromycetes species extremely flexible capacity to accumulate pollutants of various categories. The distribution of the pollutants in the soil varies from one region to another and depends on the prelevation depth.
