finch_colours {Biostatistics}

Finch colouration and mitochondrial function

Description

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.

Usage

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
