Cover image: An adult male golden snub‐nosed monkey ( Rhinopithecus roxellana ) is staring into the distance of a snowy winter in the Qinling Mountains, China. Buds and bark are the dominant foods in cold winter for this northernmost distributed leaf‐eating primate. Hou et al. applied the nutritional geometry framework to conceptualize and quantify the responses of Rhinopithecus roxellana to variations in resource quality and quantity and in nutrient requirements associated with seasonal environments. They found that captive and wild populations showed marked similarities in nutrient intake, strong year‐round maintenance of protein compared to seasonally variable fat and carbohydrate intake.
