The rheophilic European barbel Barbus barbus is an aggregative fish typically encountered
in the middle reaches of European rivers that range from southeastern England and France …

Cyprinid fish play a major role in riverine ecosystems because of their high abundance,
variety of life-history patterns, and habitat requirements. The nase (Chondrostoma nasus) is …

Artificial barriers are one of the main threats to river ecosystems, resulting in habitat
fragmentation and loss of connectivity. Yet, the abundance and distribution of most artificial …

Habitat fragmentation affects the integrity of many species, but little is known about species‐
specific sensitivity to fragmentation. Here, we compared the genetic structure of four …

Abstract The Rhine catchment in Switzerland has been transformed by a chain of
hydroelectric power stations. We addressed the impact of fragmentation on the genetic …

Rivers worldwide have been transformed into fragmented, impounded, channelized, and
flow-regulated ecosystems. These anthropogenic transformations can reduce fish …

The restoration of migration pathways for fish is crucial for the maintenance of populations in
a worldwide context of increasing river fragmentation due to the development of dams …

Most freshwater fish need to move freely through rivers to complete their life cycles. Thus,
river barriers (eg dams, culverts and gauging stations) may delay, hinder or even block their …

Migration patterns and habitat use of adult barbel (Barbus barbus) and nase (Chondrostoma
nasus) were monitored by radio telemetry over a period of 13 months along a 58-km-long …

Population structure can significantly affect genetic‐based demographic inferences,
generating spurious bottleneck‐like signals. Previous studies have typically assumed island …
