Description Fifty-four permanent treeless spring fens fed by groundwater were chosen for the study to cover a gradient of groundwater chemistry. From 2006 to 2012, samples of aquatic macroinvertebrates were collected in spring and autumn at each study site from three contrasting mesohabitats. Using Principal Coordinate Analysis (PCoA) we observed two main gradients of species composition variance, which covered 31.1% and 16.0% of the entire variation, respectively. The main compositional change (1st PCoA axis), was related mainly to the variation of total organic carbon (TOC) in substratum and partly also Ca+Mg concentration, the second main direction (2nd PCoA axis) was associated mainly with the amount of organic matter and water temperature.
