From: Response of reindeer mating time to climatic variability
Inter-annual variation of mating time from 1996 to 2013 of a semi-domesticated reindeer population at Kutuharju, northern Finland. Fitted line as well as 95% confidence interval band are provided. The dates are expressed in Julian day (JD) starting January 1st. Data points were weighted by inverse variance (i.e. regression slopes)
