In this overview (introductory article to a special issue including 14 papers), we consider all
main types of natural and artificial inland freshwater habitas (fwh). For each type, we identify …

Biodiversity monitoring via environmental DNA, particularly metabarcoding, is evolving into
a powerful assessment tool for riverine systems. However, for metabarcoding to be fully …

Throughout their history humans “tamed” not only the Danube River basin land, but also the
river and its associated wetlands, drastically influencing their characteristic habitats …

Rivers and their watersheds have been subject to various changes, including biodiversity,
caused by anthropogenic activities. The Danube River and Black Sea basin overlap the …

The headwaters of the Volga River exhibit large reaches with near‐pristine conditions, and
therefore long‐term biodiversity monitoring of this catchment can provide rare and valuable …

Abstract The Asian pond mussels (Sinanodonta spp.) are invasive species rapidly spreading
throughout the world. In Russia, non-native populations of Sinanodonta woodiana and S …

The Volga is the longest river in Europe and 16th longest in the world. The riverine
landscape of the Volga is of exceptional scientific and economic importance to Russia; the …

Fish are some of the most threatened vertebrates in the world due to their often-sensitive
response to environmental changes. Major land-use changes in the European Alps have …

A recent eDNA-metabarcoding study assessing fish diversity in the Upper Volga catchment
did not detect sterlet at any of the sampled stretches, despite recent sightings that suggest its …

Fishways are a key measure to recover longitudinal connectivity. Among them, Vertical Slot
Fishways (VSFs) have undergone extensive studies. However, very few numerical studies …
