Other than some classical ideas, large‐scale approaches to understand variation in
organismal traits (or the trait composition of an ecological community) across stream …

Triggered by the adoption of the Water Framework Directive, a variety of fish-based systems
were developed throughout Europe to assess the ecological status of lakes. This paper …

Functional diversity is regarded as a key in understanding the link between ecosystem
function and biodiversity, but its measurement is rather problematic. The two widely used …

Characterisation of biodiversity is typically based on taxonomic approaches, while much
less is known about other related aspects. Functional trait diversity is one such component of …

Fishes serve as indicators in ecological assessments of European large rivers.
Electrofishing is the standard fishing method although it is restricted to the shallow littoral …

One of the potential impacts of invasive gobies on native fish fauna is predation on eggs and
fry. Therefore, the diet composition of two invading gobiid species, the tubenose goby …

Fish species richness is an important indicator of river ecological condition but it is
particularly difficult to estimate in large unwadeable rapidly flowing rivers. Intensive multi …

We investigated diel habitat use of fish covering the littoral and pelagic zones of the Římov
Reservoir (Czech Republic) and analyzed the influence of predator presence and of shifting …

In this study, a comparison of point abundance sampling (PAS) electrofishing, angling with
two different hook sizes and trap‐based fishing was performed in a non‐wadeable river to …

River engineering measures of the last two centuries have severely impacted the fish
coenoses of all larger rivers in Europe by creating river barriers, replacing natural shores …
