Freshwater fishes are widely stocked to enhance existing stocks and create new fishery
opportunities, but quantification of ecological effects of stocking on recipient communities is …

In the present study, the biology of the pumpkinseed Lepomis gibbosus in the artificial lake
of Aoos, located in northwestern Greece, was investigated. The samplings of the …

The construction of riverine structures (weirs, bridges, or channelization) on riverbeds
causes alterations in the flow regime and channel geometry. Once a new stretch is created …

In European lakes, anthropogenic pressures have increased significantly since the 1950s,
facilitating colonisation by non-native species and increasing the potential for further …

We conducted a systematic evaluation of the correspondence in fish length data obtained
from vertical hydroacoustics and gillnetting across seven European natural lakes differing in …

Climate change and fisheries exploitation are dramatically changing the abundances,
species composition, and size spectra of fish communities. We explore whether variation in …

Aim The global patterns of body size distributions are affected by global environmental
changes (GEC), but our knowledge of the interaction effects between GEC and natural …

Water diversion for hydropower plants is one of the leading causes of habitat alteration and
biotic homogenization. The impacts of small hydropower plants on fish communities are …

An organism's body size plays an important role in ecological interactions such as predator–
prey relationships. As predators are typically larger than their prey, this often leads to a …

Predicting the impacts of species introductions long has attracted the attention of ecologists
yet there still is limited insight into how impacts on native assemblages vary with the degree …
