直接传播的寄生虫往往提供大量的信息，时间和空间特性的主机到主机的接触。在这里，我们证明了一种快速进化的病毒（猫免疫缺陷病毒，FIV）可以揭示其自然野生动物宿主（美洲狮concolor）的当代人口结构和最近的人口统计历史的细节，这些细节从宿主遗传数据中不明显，并且不可能通过其他手段获得。我们认为，快速演变的病原体可能提供一个补充的工具，在“浅”的时间研究其主机的人口动态。
Directly transmitted parasites often provide substantial information about the temporal and spatial characteristics of host-to-host contact. Here, we demonstrate that a fast-evolving virus (feline immunodeficiency virus, FIV) can reveal details of the contemporary population structure and recent demographic history of its natural wildlife host (Puma concolor) that were not apparent from host genetic data and would be impossible to obtain by other means. We suggest that rapidly evolving pathogens may provide a complementary tool for studying population dynamics of their hosts in "shallow" time.
