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 …

Novel biotic interactions in shifting communities play a key role in determining the ability of
species' ranges to track suitable habitat. To date, the impact of biotic interactions on range …

It is predicted that ecological communities will become unstable with increasing species
numbers and subsequent interspecific interactions; however, this is contrary to how natural …

Habitat selection theory enables inferences about species habitat choice across a range of
observed population densities. However, it is relatively uncommon to use habitat selection …

Aggressive encounters between invasive and native species are considered a key threat
associated with the spread of invasive species. Extrinsic factors such as habitat complexity …

An increase in habitat complexity is thought to decrease visibility and the territory size of
visually oriented animals. Hence, the addition of physical structure has been viewed as a …

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 …

In this experiment, competition was observed among native bull trout (Salvelinus
confluentus (Suckley, 1859)) and non-native brook trout (Salvelinus fontinalis (Mitchill …

A knowledge of food habits is important for evaluating interspecific competition and
predation between sympatric species. Data on food availability should be combined with …

The mechanisms underlying successful invasions by a competitively subordinate species
are poorly understood. In Japan, nonnative brown trout Salmo trutta L. have successfully …
