The relationship between predator density and mean fry telomere length in (A) the harsh stream and (B) the benign stream. Predator density categorized for clarity of presentation, but treated as a continuous variable in the analysis. Definitions of predator density: ABSENT = 0, LOW = below the mean salmonid parr density (parr/m2), HIGH = above the mean parr density (calculated separately for each stream).
