环境在病媒传播的寄生虫感染中所起的作用是了解疾病动态的中心因素之一。我们评估了新热带鸟类觅食地层和栖息地偏好如何决定血蛋白、疟原虫、白细胞体、锥虫和丝虫属寄生虫的感染，并测试了这些宿主-寄生虫组合中的系统发育信号。我们对科学文献进行了广泛的搜索，并创建了血寄生虫调查数据库。我们收集了寄主体量、觅食地层、栖息地偏好和迁徙状态的数据，并使用系统发育贝叶斯框架检验了寄主生态特征是否可以预测每个血寄生虫的发生和流行。疟原虫的种类往往会感染热带森林中的鸟类，而海拔环境中的鸟类可能会感染白细胞增殖体的种类。在低地森林中，鸟类感染丝虫或锥虫的概率较高。生活在热带纬度人类环境和干燥栖息地的鸟类更容易受到血蛋白菌种的感染。寄主觅食层也有影响，在中高层和冠层觅食的鸟类更容易被血蛋白和丝状线虫感染。我们还确定了宿主-寄生虫与任何血寄生虫感染新热带鸟类的可能性之间的系统发育信号，这些血寄生虫在更接近的物种中更相似。我们提供了一个有用的框架来识别与血寄生虫感染相关的环境，这也有助于发现由于土地退化和气候变化而具有潜在适合血寄生虫感染的地区。这篇文章受版权保护。版权所有。
The role that the environment plays in vector-borne parasite infection is one of the central factors for understanding disease dynamics. We assessed how Neotropical bird foraging strata and habitat preferences determine infection by parasites of the genera Haemoproteus, Plasmodium, Leucocytozoon and Trypanosoma and filarioids, and tested for phylogenetic signal in these host-parasite associations. We performed extensive searches of the scientific literature and created a database of hemoparasite surveys. We collected data on host body mass, foraging strata, habitat preference and migratory status, and tested if host ecological traits predict each hemoparasite occurrence and prevalence using a phylogenetic Bayesian framework. Species of Plasmodium tend to infect birds from tropical forests while birds from altitudinal environments are likely to be infected by species of Leucocytozoon. The probability of a bird being infected by filarioid or Trypanosoma is higher in lowland forests. Bird species that occur in anthropic environments and dry habitats of tropical latitudes are more susceptible to infection by species of Haemoproteus. Host foraging strata is also influential and bird species that forage in the mid-high and canopy strata are more prone to infection by species of Haemoproteus and filarioids. We also identified phylogenetic signal for host-parasite associations with the probability of infection of Neotropical birds by any hemoparasite being more similar among more closely related species. We provided a useful framework to identify environments that correlate with hemoparasite infection, which is also helpful for detecting areas with potential suitability for hemoparasite infection due to land conversion and climate change.
