Many species of salmonids have been stocked into waters outside of their native range. The
invasiveness and impact of these species on native species varies depending on their …

A proper understanding of radioactive contamination levels of food resources near the
Fukushima Dai-ichi Nuclear Power Plant is necessary to estimate the potential effects of …

When, where, and what predators prey upon salmon is fundamental to understanding their
mortality in a given region. We reviewed the available information about predators of three …

Predator–prey interactions must be considered when aiming to enhance populations by

To elucidate 137 Cs contamination levels and mechanisms of fish inhabiting river and pond
environments near the Fukushima Dai-ichi Nuclear Power Plant, 137 Cs activity …

Pulsed supplies of prey generally increase predator food intake. However, it is unclear
whether this holds true when predators and pulsed prey are in the same guild (ie intraguild …

Intraspecific trophic variability has important ecological and evolutionary implications, and is
driven by multiple interacting factors. Functional traits and environmental conditions are …

Invasion status and impacts of nonnative brook trout (Salvelinus fontinalis) in a Hokkaido
stream were investigated with field surveys and genetic analyses. Nonnative brook trout was …

Species assemblages composed of non-native and native fishes are found in freshwater
systems throughout the world, and interactions such as interspecific competition that may …

We explored potential negative effects of exotic brown trout (Salmo trutta) on native sculpin
