Biodiversity patterns along elevation gradients have long been studied for plants and animals, but only quite recently soil microorganisms, especially protists (eukaryotes excluding plants, fungi). Microorganisms shorter generation times than macroorganisms, their abundance, diversity, community structure are known to vary rapidly in response abiotic biotic factors. If microbial diversity varies more seasonally spatially, a single sampling campaign an gradient, with contrasted phenologies, could introduce bias into biodiversity studies comparing multiple across different seasons, habitats, regions or latitudes. To address this question, we investigated the relative magnitude of spatial versus temporal (alpha diversity) turnover (beta protist communities two distant European mountain ranges.

The integration of satellite data from the Copernicus Land Monitoring Service (CLMS) with ground-based measurements represents a pioneering approach to assessment leaf area index (LAI) and in situ biomass at grasslands Poland Norway. aim this study was develop method for assessing grass growth conditions predicting yield based on Sentinel-2 CLMS products. LAI values derived were compared in-situ grassland plots two regions Podlaskie (PL84) Wielkopolskie (PL41). Small random statistical errors observed differences represent significant opportunity use relationship model prediction. NDII calculated using Sentinel2 considered important humid areas This relational prediction could provide valuable information farmers, improving their ability manage effectively. As result research, models developed has been predict fresh an R2 accuracy 0.72 first cut, 0.81 second cut 0.91 third cut. allows farmers effectively monitor throughout growing season.
