由于全球和当地环境（包括气候）的变化，蜱虫和蜱传病原体的地理范围正在发生变化。在这篇综述中，我们通过对基本繁殖数（R0）的影响，探讨了蜱和蜱传病原体种类和菌株范围变化的驱动因素，以及蜱和蜱传病原体侵入合适环境的传播机制。以莱姆病媒介和病原体不断扩大的地理分布为例，我们研究了在范围扩大过程中蜱传病原体多样性的预期，并将其与目前观察到的情况进行比较。最后，我们探讨了历史种群和范围的扩张和收缩如何反映在近年来蜱和蜱传病原体的系统发育地理学中，并得出结论，对当前变化的蜱和蜱传播病原体范围和多样性的综合研究与系统发育地理学分析，可能有助于我们更好地预测未来的入侵和多样性模式。
The geographic ranges of ticks and tick-borne pathogens are changing due to global and local environmental (including climatic) changes. In this review we explore current knowledge of the drivers for changes in the ranges of ticks and tick-borne pathogen species and strains via effects on their basic reproduction number (R0), and the mechanisms of dispersal that allow ticks and tick-borne pathogens to invade suitable environments. Using the expanding geographic distribution of the vectors and agent of Lyme disease as an example we then investigate what could be expected of the diversity of tick-borne pathogens during the process of range expansion, and compare this with what is currently being observed. Lastly we explore how historic population and range expansions and contractions could be reflected in the phylogeography of ticks and tick-borne pathogens seen in recent years, and conclude that combined study of currently changing tick and tick-borne pathogen ranges and diversity, with phylogeographic analysis, may help us better predict future patterns of invasion and diversity.
