TABLE 2.

Statistical summary of the final linear mixed model explaining variation in relative telomere length (log₁₀). Intercept represents females for the variable Sex and represents low nutrient streams for the variable Treatment. See Section 2 and Table S2 for an overview of the initial habitat variables considered. Centered_Density refers to within‐stream local salmon density, while Mean_Granulometric Index refers to differences among streams in substrate topography. N = 413
