Abstract

Amazonia avian malaria parasite biogeography parasite colonization parasite dispersal parasite diversification
Amazonia is the primary source of haemosporidian diversity for South American biomes. Yet, our understanding of the contribution of each area of endemism and the biogeographical processes that generated such diversity in this group of vector transmitted parasites remains incomplete. For example, a recently formed fluvial island in the Amazon delta - Marajó Island, is composed of avian lineages from adjacent Amazonian areas of endemism, but also from open habitats, such as Cerrado. This raises the question: Is the parasite assemblage found in avian hosts on this island formed by parasite lineages from adjacent Amazonian areas of endemism or Cerrado? Here, we assessed the spatiotemporal evolution of Plasmodium and Parahaemoproteus parasites. Our biogeographic analysis showed that dispersal dominated Plasmodium diversification, whereas duplication was more frequent for the genus Parahaemoproteus. We show that the Inambari area of endemism was the primary source for Plasmodium diversity on Marajó Island, but that this island received more Parahaemoproteus lineages from Cerrado than any Amazonian area of endemism. The unique patterns of dispersal for each parasite genus coupled with their propensity to shift hosts locally may have facilitated their diversification across Amazonia, suggesting that differences in deep evolutionary history may have constrained their colonization of Marajó Island.
