“…Macrozoobenthic invertebrates are an essential component of freshwater ecosystems, both as bioindicators (Odountan and Abou, 2015;Singh et al, 2019;Singh and Sharma, 2020;Cupșa et al, 2010Cupșa et al, , 2020 and also as a food source for various aquatic vertebrates, like amphibians (Fasola and Canova, 1992 Bănăduc, 2014). Therefore, the main hypothesis of our study was outlined considering the fact that if the small watercourses fed by springs are able to ensure appropriate conditions for Umbra krameri, they must have remarkable macrozoobenthic biodiversity.…”

Macrozoobenthic invertebrate assemblages are a very important component of water ecosystems that reflect water quality. The evaluation of these assemblages in the Jiului Corridor Natura 2000 site can highlight the natural value of aquatic invertebrate biodiversity. Thus, our study aimed to analyze seven streams from the Jiu Corridor Natura 2000 site from the point of view of the macrozoobenthic invertebrate assemblages' structure. The samples were collected in June 2020. Also, we measured the most important physicochemical parameters of the water. In the sample sites, we found a number of 31 taxa. There were differences between the sites depending on the riverbed type, hydrology, and human impact intensity. Totally, we have identified 15232 individuals of macrozoobenthic invertebrates. Even though the communities in the seven studied watercourses were different, these differences were not statistically significant. This fact, correlated with the high number of individuals and taxa, suggests the relict character of the macrozoobenthic invertebrate communities in the studied small watercourses. These aquatic habitats preserve the region`s biodiversity from before anthropic transformations.
