A larger body size confers many benefits, such as increased reproductive success, ability to evade predators and increased competitive ability and social status. However, individuals rarely maximize their growth rates, suggesting that this carries costs. One such cost could be faster attrition of the telomeres that cap the ends of eukaryotic chromosomes and play an important role in chromosome protection. A relatively short telomere length is indicative of poor biological state, including poorer tissue and organ performance, reduced potential longevity and increased disease susceptibility. Telomere loss during growth may also be accelerated by environmental factors, but these have rarely been subjected to experimental manipulation in the natural environment. Using a wild system involving experimental manipulations of juvenile Atlantic salmon Salmo salar in Scottish streams, we found that telomere length in juvenile fish was influenced by parental traits and by direct environmental effects. We found that ... : Fry weight LMMData contained in this spreadsheet relates to the linear mixed-effect model explaining variation in fry weight (g).Fry survival LMMData contained in this spreadsheet relates to the linear mixed-effect model explaining variation in fry survival.Embryo RTL LMMData contained in this spreadsheet relates to the linear mixed-effect model explaining variation in embryo telomere length.Fry RTL LMMData contained in this spreadsheet relates to the linear mixed-effect model explaining variation in fry telomere length. ...
