Characterizing the diversity and structure of host–parasite communities is crucial to understandingtheir eco-evolutionary *** and related haemosporidian parasites are responsible forfitness loss and mortality in bird species ***,despite exhibiting the greatest ornithologicalbiodiversity,avian haemosporidians from Neotropical regions are quite ***,we analyze the genetic diversity of bird haemosporidian parasites(Plasmodium andHaemoproteus)in 1,336 individuals belonging to 206 bird species to explore for differences in diversityof parasite lineages and bird species across 5 well-differentiated Peruvian *** 70 different haemosporidian lineages infecting 74 bird *** showed that 25 out ofthe 70 haplotypes had not been previously ***,we also identified 81 new host–parasite interactions representing new host records for these haemosporidian *** outcomesrevealed that the effective diversity(as well as the richness,abundance,and Shannon–Weaver index)for both birds and parasite lineages was higher in Amazon basin ***,we also showed that ecoregions with greater diversity of bird species also had highparasite richness,hence suggesting that host community is crucial in explaining parasite *** parasites were found in ecoregions with lower bird diversity,implying that the abundanceand richness of hosts may shape the exploitation strategy followed by haemosporidian *** outcomes reveal that Neotropical region is a major reservoir of unidentified *** studies analyzing host distribution and specificity of these parasites inthe tropics will provide important knowledge about phylogenetic relationships,phylogeography,and patterns of evolution and distribution of haemosporidian parasites.
