Finch colouration and mitochondrial function

Data on the hue of the red feathers and a series of measures of mitochondrial function in 36 male house finches Haemorhous mexicanus at a time when they were moulting and therefore actively producing red carotenoids. data

data("finch_colours")

Format

A data frame with 36 observations on the following 5 variables.

• ID: ID number for the individual bird
• Hue: Hue of the red feathers. Lower values are redder
• C1RCR: "Respiratory Control Ratio", calculated by dividing the maximum respiration rate by the basal rate
• C1MMP: Mitochondrial Membrane Potential
• PGC_1a: The level of a protein which activates transcription in mitochondrial biogenesis
