Personality, foraging behavior and specialization: integrating behavioral and food web ecology at the individual level

BJ Toscano, NJ Gownaris, SM Heerhartz, CJ Monaco - Oecologia, 2016‏ - Springer
Behavioral traits and diet were traditionally thought to be highly plastic within individuals.
This view was espoused in the widespread use of optimality models, which broadly predict …

Partial migration: niche shift versus sexual maturation in fishes

B Jonsson, N Jonsson - Reviews in Fish Biology and Fisheries, 1993‏ - Springer
Many fish populations have both resident and migratory individuals. Migrants usually grow
larger and have higher reproductive potential but lower survival than resident conspecifics …

Metabolic rate, social status and life-history strategies in Atlantic salmon

NB Metcalfe, AC Taylor, JE Thorpe - Animal Behaviour, 1995‏ - Elsevier
An animal's relative social status has major short-and long-term consequences, yet its
determinants are rarely known. Here a strong relationship between status and standard …

A critical review of adaptive genetic variation in Atlantic salmon: implications for conservation

C Garcia de Leaniz, IA Fleming, S Einum… - Biological …, 2007‏ - Wiley Online Library
Here we critically review the scale and extent of adaptive genetic variation in Atlantic salmon
(Salmo salar L.), an important model system in evolutionary and conservation biology that …

The effects of chronic plasma cortisol elevation on the feeding behaviour, growth, competitive ability, and swimming performance of juvenile rainbow trout

TR Gregory, CM Wood - Physiological and Biochemical …, 1999‏ - journals.uchicago.edu
Plasma cortisol elevation, a common consequence of stress, occurs in salmonids of
subordinate rank; these fish acquire a smaller share of available food and grow more slowly …

Genetic divergence and interactions in the wild among native, farmed and hybrid Atlantic salmon

S Einum, IA Fleming - Journal of Fish Biology, 1997‏ - Wiley Online Library
There is concern that the progeny resulting from the spawnings of escaped farmed Atlantic
salmon may compete with and disrupt native salmon populations. This study compared, both …

Juvenile migration in brown trout: a consequence of energetic state

T Forseth, TF Nesje, B Jonsson… - Journal of Animal …, 1999‏ - Wiley Online Library
1. We explored the mechanisms determining age and size at juvenile migration in brown
trout Salmo trutta L. A 133Cs tracer methodology was used to estimate food consumption of …

Aggression and growth depression in juvenile Atlantic salmon: the consequences of individual variation in standard metabolic rate

CJ Cutts, NB Metcalfe, AC Taylor - Journal of Fish Biology, 1998‏ - Wiley Online Library
In aquaculture, competitive interactions for food are a major source of growth rate variation,
since they result in aggressive individuals acquiring a disproportionate amount of food and …

Repeatability of standard metabolic rate, active metabolic rate and aerobic scope in young brown trout during a period of moderate food availability

T Norin, H Malte - Journal of Experimental Biology, 2011‏ - journals.biologists.com
Standard metabolic rate (SMR) and active metabolic rate (AMR) are two fundamental
physiological parameters providing the floor and ceiling in aerobic energy metabolism. The …

Flexible niche partitioning via a foraging mode shift: a proposed mechanism for coexistence in stream‐dwelling charrs

S Nakano, KD Fausch, S Kitano - Journal of Animal Ecology, 1999‏ - Wiley Online Library
Foraging behaviour, diet and interference competition were examined for two
morphologically similar charrs, Salvelinus malma (Dolly Varden) and S. leucomaenis (white …
