A female golden snub-nosed monkey (Rhinopithecus roxellana) is nursing her baby at Qinling Mountains, China. Golden snub-nosed monkey is an endangered primate living in temperate deciduous forests at the edge of the global distribution range for folivorous primates, low temperature and resource scarcity are co-occurrent challenges in winter, bark and buds are primary during this period. Hou et al. constructed quantitative energy budgets and examined the integrated strategies, they found that despite its suit of integrated homeostatic responses, the confluence of low temperatures and resource limitation during winter places this edge-of-range primate close the threshold of what is energetically viable. Photo by Jianqiang Zhao.
