From: Weather influences M. arvalis reproduction but not population dynamics in a 17-year time series
(A) Proportion of reproductive females in April and October from 1982 to 1996 (and in July and August when available.) Population dynamics are indicated with color - populations were either declining (red) or stable/increasing (blue). (B) Relationship between the number of foetuses per female and the proportion of reproductive females in the population. The solid line represents the fit of a Binomial GLM (R2 = 0.22, p < 0.0001).
