本文讨论了气候变化对禽流感病毒（Al病毒）生态的影响，这可能是共同进化的迁徙水鸟，病毒也坚持在亚北极水体的主机外。气候变化几乎肯定会改变鸟类迁徙，影响禽流感病毒的传播周期，并直接影响病毒在宿主外的存活。这些变化的联合净效应是相当不可预测的，但水禽种群中的Al病毒循环很可能会继续无休止的适应和进化。在家禽中，对环境因素对高致病性禽流感传播和持续性的直接影响知之甚少，无法推断气候变化的可能影响。然而，可能的间接联系，通过鸭作物种植的分布变化进行了讨论。
This paper discusses impacts of climate change on the ecology of avian influenza viruses (Al viruses), which presumably co-evolved with migratory water birds, with virus also persisting outside the host in subarctic water bodies. Climate change would almost certainly alter bird migration, influence the Al virus transmission cycle and directly affect virus survival outside the host. The joint, net effects of these changes are rather unpredictable, but it is likely that Al virus circulation in water bird populations will continue with endless adaptation and evolution. In domestic poultry, too little is known about the direct effect of environmental factors on highly pathogenic avian influenza transmission and persistence to allow inference about the possible effect of climate change. However, possible indirect links through changes in the distribution of duck-crop farming are discussed.
