项目摘要
Studying the diversity of symbionts offers a unique window to observe ecological and evolutionary dynamics between interdependent organisms. Further, like a canary in a coal mine, host switching by symbionts may reveal emerging risk factors leading to infectious diseases in hosts. On the other hand, extinction of symbionts inform can inform us about the impacts of environmental change. Information on symbionts diversity is limited, however, since they are relatively understudied organisms. This project investigates lizards and their haemosporidian symbionts in sub-Saharan Africa. Haemosporida is a diverse group of vector-borne protozoan symbionts found in terrestrial vertebrates in almost all world ecosystems. Although some species have been studied because of their link to malaria in birds and humans, haemosporidian symbionts in African lizards are poorly known. This project provides training opportunities for graduate and undergraduate students. Local assemblages of African lizards include sets of taxa differing in degree of ecological and phylogenetic distinctiveness. Unlike birds, lizards do not disperse broadly, and local assemblages are less diverse. These characteristics reduce bias in host species censuses, allowing us to test hypotheses about the factors driving host/symbiont biodiversity. Thus, this study aims to (1) advance our understanding of Haemosporida species delimitation by formalizing an approach that integrates morphological, molecular, and ecological data, (2) generate new knowledge on the processes driving haemosporidian species diversity by studying newly detected Haemosporida species in host clades across their distribution in distinct biomes, (3) enrich biodiversity sciences by developing standards for symbiont-host data integration, and (4) generate knowledge on the regional herpetofauna with new specimens and metadata. This study will provide new insights into regional evolutionary and ecological processes by considering Haemosporida as true elements of biodiversity rather than as traits or pathogens of their hosts.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
研究共生体的多样性为观察相互依赖的生物之间的生态和进化动力学提供了一个独特的窗口。此外,就像煤矿里的金丝雀一样,共生体的宿主转换可能会揭示导致宿主感染性疾病的新风险因素。另一方面,共生体的灭绝可以告诉我们环境变化的影响。然而,关于共生体多样性的信息是有限的,因为它们是相对研究不足的生物。该项目调查了撒哈拉以南非洲的蜥蜴及其血孢子虫共生体。血孢子虫是一组多样的媒介传播原生动物共生体,几乎在世界所有生态系统的陆生脊椎动物中发现。虽然一些物种已经被研究,因为它们与鸟类和人类的疟疾有关,但非洲蜥蜴中的血孢子虫共生体却知之甚少。该项目为研究生和本科生提供培训机会。非洲蜥蜴的地方组合包括不同程度的生态和系统发育的独特性的类群。与鸟类不同的是,蜥蜴并不广泛分布,当地的群落也没有那么多样化。这些特征减少了宿主物种普查中的偏差,使我们能够测试有关驱动宿主/共生生物多样性的因素的假设。因此,本研究旨在(1)通过整合形态学,分子和生态学数据的方法,促进我们对血孢子虫物种划分的理解,(2)通过研究新发现的血孢子虫物种在不同生物群中的宿主分支中的分布,产生关于驱动血孢子虫物种多样性的过程的新知识,(3)通过制定共生体-宿主数据整合标准,丰富生物多样性科学;(4)通过新的标本和元数据,产生关于区域两栖动物区系的知识。这项研究将提供新的见解区域进化和生态过程考虑血孢子虫作为生物多样性的真正要素,而不是作为其主机的性状或病原体。这个奖项反映了NSF的法定使命,并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
