Relationship between egg-laying day and spring temperature. Descriptive plot of egg-laying day of individual sand lizard (Lacerta agilis) females versus spring temperature/cumulated degrees (annual cumulated sums of mean temperature over April-May in 1987–1991 and 1998–2007). The figure does not comprise all individual data points, but includes the highest and lowest number of days recorded in each year (parameter estimate −4.971 ± 1.957, P = 0.0244, n = 356)
