Abstract

Host-parasite relationships are often cited as classic examples of coevolution, but parasites are also able to switch hosts. Is the distribution of parasites across a phylogeny affected by the phylogenetic distance between potential hosts? Engelstädter and Fortuna (2019) provide evidence that the success of host switches is linked to phylogenetic distance between potential hosts, as well as the diversification rate and shape of host phylogenetic trees.

摘要

寄生虫与宿主的关系常被引为协同进化的经典范例，但寄生虫也能够更换宿主。寄生虫在系统发育树上的分布是否受潜在宿主间系统发育距离的影响？Engelstädter 和 Fortuna（2019）的研究结果表明，宿主转换的成功与否与潜在宿主间的系统发育距离、宿主系统发育树的多样化速率和形状有关。
