The list of the water mite species found in Romania is still incomplete. This is because of the interruption of the studies that had taken place in this country, especially in the first part of the 20-th century regarding the water mite distribution and ecology.
This paper offers a presentation of the water mite fauna from the rivers situated in the V├ón─âtori Neam┼ú Natural Park area, as well as a glimpse on the differences in ecology tolerance ranges of the identified water mite taxa.
We used qualitative sampling to obtain specimens required for systematic studies. Several general physico-chemical indicators were also measured in each of the sampling stations: thermal conditions, pH, oxygenation conditions given by dissolved oxygen depletion (DO depletion), Total Dissolved Salts (TDS), salinity, dissolved inorganic nitrogen forms (N-ammonium, N-nitrite and N-nitrate) and soluble reactive phosphorous (SRP).
The results obtained offers a glimpse over the biodiversity of the water mites collected from the studied area, as well as some strong correlations among the measured physico-chemical parameters and the presence or absence of the identified water mite taxa.
