Heat stress reduces growth rate of red deer calf: Climate warming implications

female calf. (JPEG) S4 Fig. Supplementary material. Response of mother body weight through lactation (from birth to forced weaning day 143) to mother age (years) and calf age (days) of the final model in Table 5, all other variables in the model fixed at their mean values. Dashed line: ± standard error. Response variable has been centred by subtraction of the mean value. (JPG) Acknowledgments Jose´ Marı´a Luja´n Go´mez attended the animals on a daily basis. David Walker, Andrew McWil- liam and two anonymous reviewers revised a version of this paper. Author Contributions Conceptualization: F. J. Pe´rez-Barberı´a. Data curation: F. J. Pe´rez-Barberı´a, J.
