Figure 6: Elk births and carnivore use of predicted elk parturition habitat as a function of Julian week in northeastern Oregon, 2016-2019. a) The density of elk births as a function of Julian week. Bars indicate counts of births per week and the blue curve is a normal distribution fit to the data. The dashed tan line indicates the mean birth date. b-d) Predictions from linear mixed models relating the weekly average resource selection function (RSF) score for parturient elk at carnivore GPS relocations for male bears (b), female bears (c), and cougars (d) as a quadratic function of Julian week. The solid blue lines display the model predictions for carnivore use of elk parturition habitat and the gray shading represents its 95% confidence interval.P -values correspond to the outcome of likelihood ratio tests assessing whether the models containing quadratic terms for Julian week were supported over models with only a linear term for Julian week.
