Global climate change is altering the ecology of infectious agents and driving the emergence of disease in people, domestic animals, and wildlife. We present a novel, empirically based, predictive model for the impact of climate warming on development rates and availability of an important parasitic nematode of muskoxen in the Canadian Arctic, a region that is particularly vulnerable to climate change. Using this model, we show that warming in the Arctic may have already radically altered the transmission dynamics of this parasite, escalating infection pressure for muskoxen, and that this trend is expected to continue. This work establishes a foundation for understanding responses to climate change of other host-parasite systems, in the Arctic and globally.
全球气候变化正在改变传染病原体的生态,并促使人类、家畜和野生动物中疾病的出现。我们提出了一个新的、基于实证的预测模型,用于评估气候变暖对加拿大北极地区麝牛一种重要寄生线虫发育速率和可获得性的影响,该地区特别容易受到气候变化的影响。利用这个模型,我们表明北极地区的变暖可能已经从根本上改变了这种寄生虫的传播动态,增加了麝牛的感染压力,并且这种趋势预计将持续下去。这项工作为理解北极地区和全球其他宿主-寄生虫系统对气候变化的反应奠定了基础。
