Journal ArticleDOI
Habitat requirements of Atlantic salmon and brown trout in rivers and streams
TL;DR: It is prudent to accept that although manipulations of habitat may appear to be beneficial when considered locally, they should be measured and assessed where possible in terms of the production of returning adults and/or high quality smolts.
Journal ArticleDOI
What causes intraspecific variation in resting metabolic rate and what are its ecological consequences
TL;DR: It is demonstrated that diverse factors, such as genotypes, maternal effects, early developmental conditions and personality differences contribute to variation in individual RMR, and that the fitness consequences of a given RMR may be context-dependent.
Journal ArticleDOI
The natural control of salmon and trout populations in streams
TL;DR: In this article, a review of the current understanding of factors controlling salmonid populations in streams and how this contributes to better fisheries management is presented, with an emphasis on understanding the uncertainties and risks inherent in modelling wild populations.
Journal ArticleDOI

TL;DR: Positive‐stranded genomic RNA of coronavirus MHV and its six subgenomic mRNAs are synthesized in the cytoplasm of the host cell by a mechanism which appears to involve an unusual and specific ‘polymerase jumping’ event.
Journal ArticleDOI
Physiological effects of dominance hierarchies: laboratory artefacts or natural phenomena?
TL;DR: The need is identified for a well structured experimental approach to the investment of the causes and consequences of hierarchies if the ecology of wild fish is to be modelled eectively based on physiological processes and it is suggested that the further development and application of techniques for monitoring physiologies of fish in the wild is important.
