Rapid climate change, is radically, and probably irreversibly, altering arctic ecosystems. Infectious disease, parasitic disease in particular, together with climate warming, may be playing an important role in recent and widespread caribou population declines across the North American Arctic. Climate change could increase the impact of parasitic disease in arctic ungulates by: (1) changing the transmission patterns of the existing parasites; and (2) introduction of new parasite species to naïve populations.

快速的气候变化正在从根本上，而且可能是不可逆转地改变北极的生态系统。传染病，特别是寄生虫病，加上气候变暖，可能在北美北极地区最近广泛的驯鹿数量下降中发挥了重要作用。气候变化可能通过以下方式增加北极有蹄类动物寄生虫病的影响：（1）改变现有寄生虫的传播模式;（2）将新的寄生虫物种引入幼稚种群。
