We analysed, in the context of the sustainable management of rivers, the variability in the structure and diversity of ephemeropteran larvae communities in relation to the Timiş River biotope factors. Our research revealed that high diversity of the Ephemeroptera was associated with the river sectors having a heterogeneous structure where runs, poo...

The landscape is a visible feature of land that integrates natural and human-made features (cultural, social, and economic) and dynamics at different scales. Ground, water, and society primarily determine the characteristics of the landscape. When at least one of these features changes, the landscape changes. Anthropic dynamics on the landscape are...
