When cultured Atlantic salmon are released into nature, they compete with wild fish for food,
space, and breeding partners. As a result of morphological, physiological, ecological, and …

A species may partition its realized ecological niche along bionomic and scenopoetic axes
due to intraspecific competition for limited resources. How partitioning manifests depends on …

Basal or standard metabolic rate (SMR) has been found to exhibit substantial intraspecific
variation in a range of taxa, but the consequences of this variation are little understood. Here …

Interference is expected to occur at feeding areas between species with a similar diet, but
few studies have tested this idea for wild ungulates. We analysed interactions between …

Variations in distributions and behaviours of Atlantic salmon Salmo salar in allopatry
(homogeneous) and in sympatry with brown trout Salmo trutta (mixed) were observed …

The brown trout (Salmo trutta) is a species of Eurasian origin, but at has become naturalized
in many other parts of the world. It has an outstanding socio-economic importance, both in …

The benefit of monopolizing a limited resource is influenced by competitor density and by
the relative competitive ability of defenders and intruders. Nevertheless, few studies have …

Abstract Changes in environmental conditions affect social interactions and thus may modify
an individual's competitive ability within a social group. We subjected three‐spined …

Although non‐native species can sometimes threaten the value of ecosystem services, their
presence can contribute to the benefits derived from the environment. In the G reat L akes …

Timing of offspring arrival (ie hatching, birth or emergence from nests) is commonly shown to
have strong effects on their performance through body size and prior residency effects, but …
