Open AccessWhat is a fish? The life and legend of David L.G. Noakes
David Lloyd George Noakes (1942–2020) is best known for his insatiable curiosity, his quick wit and dry sense of humor, his scientific contributions to the field of animal behaviour, and his ability to form an...

On the relevance of animal behavior to the management and conservation of fishes and fisheries
There are many syntheses on the role of animal behavior in understanding and mitigating conservation threats for wildlife. That body of work has inspired the development of a new discipline called conservation...

Stream characteristics associated with feeding type in silver (Ichthyomyzon unicuspis) and northern brook (I. fossor) lampreys and tests for phenotypic plasticity
In most lamprey genera, “paired” species exist in which the larvae are morphologically indistinguishable but adult feeding type differs. The lack of diagnostic genetic differences in many pairs has led to sugg...

Individual differences in foraging behavior and cortisol levels in recently emerged brook charr (Salvelinus fontinalis)
Recently emerged brook charr (Salvelinus fontinalis) foraging in still-water pools along the sides of streams tend to be either sedentary, feeding from the lower portion of the water column (a sit-and-wait tactic...

Foraging behaviour and brain morphology in recently emerged brook charr, Salvelinus fontinalis
Recently emerged brook charr (Salvelinus fontinalis) foraging in still-water pools along the sides of streams are either active, feeding on insects from the upper portion of the water column away from the stream ...

Temporal Persistence of Resource Polymorphism in Brook Charr, Salvelinus Fontinalis
Resource polymorphisms are believed to be an important intermediate step in competitive sympatric speciation. Reports of resource polymorphisms in fishes are becoming more common, but tests of the temporal per...

Adaptive peaks and alternative foraging tactics in brook charr: evidence of short-term divergent selection for sitting-and-waiting and actively searching
Some recently emerged brook charr (Salvelinus fontinalis) inhabiting still-water pools along the sides of streams are sedentary and eat crustaceans from the lower portion of the water column. Others are more act...

Tissue concentrations of RNA and protein for juvenile brook trout (Salvelinus fontinalis): lagged responses to fluctuations in food availability
To be useful as short-term indices of nutritional status when food availability varies, wet weight-at-length and tissue concentrations of nucleic acids and protein must covary closely with a fish's recent feed...

Morphological and behavioural differences among recently-emerged brook charr,Salvelinus fontinalis, foraging in slow- vs. fast-running water
Morphology and resource use were compared among recently-emerged brook charr,Salvelinus fontinalis, sampled from field locations differing in current speed. Individuals from faster running water were slightly lon...

The association between amount of red muscle and mobility in fishes: A statistical evaluation
It is commonly accepted that more active fishes have a greater proportion of red muscle in their trunk musculature than do less active fishes. Further, the proportion of red muscle has been used to classify fi...

Brood dispersal and multiple central place foraging by Lapland longspur parents
Lapland longspur chicks continued to be fed by their parents for 2 weeks after nest departure. Shortly after they left the nest, broods were divided evenly into two units each tended by a single parent. Female...
