The relationship between calving date and spring onset for two herds with individually marked females.

<p>Squares are data from Spalca <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0056450#pone.0056450-Tveraa2" target="_blank">[37]</a> and triangles are data from Njeaiddan <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0056450#pone.0056450-Brdsen3" target="_blank">[39]</a>. The dashed line indicates the 1∶1 relationship.</p

Estimates from linear mixed-effects models (LME) for the model with lowest AIC relating calf body mass in autumn and reproductive success to population density (log[Number of females]), spring onset (SO) and peak plant productivity.

Red solid lines give estimated mean and standard error (red dashed lines) using generalized additive mixed modelling. Grey lines are estimated relationships for individual populations based on linear regressions.</p
