“…Although we still lack a comprehensive understanding of the diversity, host breadth, and geographic distribution of avian haemosporidian lineages in northern South America, our results suggest that the Magdalena River Valley likely harbors several generalist parasites because at least two Plasmodium lineages (PADOM 11 and Plasmodium nucleophilum ‐DENPET03) and one Haemoproteus ( H. coatneyi ) infecting Eucometis penicillata have been found in multiple hosts and areas in the Americas, including the Antilles and North America (Durrant et al., ; González, Lotta, García, Moncada, & Matta, ; Harrigan et al., ; Kimura, Darbro, & Harrington, ; Lacorte et al., ; Levin et al., ; Marzal et al., ; Moens & Pérez‐Tris, ; Oakgrove et al., ; Ricklefs et al., ; Roos, Belo, Silveira, & Braga, ; Smith & Ramey, ). In addition, the one Plasmodium lineage infecting Manacus manacus has been previously found in another species of piprid (Blue‐crowned Manakin, Lepidothrix coronata ) in Ecuador, Brazil, and Costa Rica (Bosholn, Fecchio, Silveira, Braga, & Anciães, ; Moens & Pérez‐Tris, ).…”

Environmental factors strongly influence the ecology and evolution of vector‐borne infectious diseases. However, our understanding of the influence of climatic variation on host–parasite interactions in tropical systems is rudimentary. We studied five species of birds and their haemosporidian parasites (Plasmodium and Haemoproteus) at 16 sampling sites to understand how environmental heterogeneity influences patterns of parasite prevalence, distribution, and diversity across a marked gradient in water availability in northern South America. We used molecular methods to screen for parasite infections and to identify parasite lineages. To characterize spatial heterogeneity in water availability, we used weather‐station and remotely sensed climate data. We estimated parasite prevalence while accounting for spatial autocorrelation, and used a model selection approach to determine the effect of variables related to water availability and host species on prevalence. The prevalence, distribution, and lineage diversity of haemosporidian parasites varied among localities and host species, but we found no support for the hypothesis that the prevalence and diversity of parasites increase with increasing water availability. Host species and host × climate interactions had stronger effects on infection prevalence, and parasite lineages were strongly associated with particular host species. Because climatic variables had little effect on the overall prevalence and lineage diversity of haemosporidian parasites across study sites, our results suggest that independent host–parasite dynamics may influence patterns in parasitism in environmentally heterogeneous landscapes.

“…A phylogeny was constructed to assess genetic relationships among parasite lineages detected in blue-winged teal and those previously reported for other waterfowl in North America and South America (Ramey et al 2012(Ramey et al , 2013b(Ramey et al , 2014(Ramey et al , 2015bMatta et al 2014;Reeves et al 2015;Smith and Ramey 2015). Haplotypes identified in more than one waterfowl species per location (i.e., USA state, Canadian province, or Neotropical country) were represented by a single sequence per sampling locale.…”

Evidence for the exchange of blood parasites between North America and the Neotropics in blue-winged teal (Anas discors)

Blue-winged teal (Anas discors) are abundant, small-bodied dabbling ducks that breed throughout the prairies of the northcentral USA and central Canada and that winter in the southern USA and northern Neotropics. Given the migratory tendencies of this species, it is plausible that blue-winged teal may disperse avian pathogens, such as parasites causing avian malaria, between spatially distant areas. To test the hypothesis that blue-winged teal play a role in the exchange of blood parasites between North America and areas further south, we collected information on migratory tendencies of this species and sampled birds at spatially distant areas during breeding and non-breeding periods to diagnose and genetically characterize parasitic infections. Using a combination of band recovery data, satellite telemetry, molecular diagnostics, and genetic analyses, we found evidence for (1) migratory connectivity of blue-winged teal between our sampling locations in the Canadian prairies and along the US Gulf Coast with areas throughout the northern Neotropics, (2) parasite acquisition at both breeding and non-breeding areas, (3) infection of blue-winged teal sampled in Canada and the USA with Plasmodium parasite lineages associated with the Neotropics, and (4) infection of blue-winged teal with parasites that were genetically related to those previously reported in waterfowl in both North America and South America. Collectively, our results suggest that blue-winged teal likely play a role in the dispersal of blood parasites between the Neotropics and North America, and therefore, the targeting of this species in surveillance programs for the early detection of Neotropical-origin avian pathogens in the USA may be informative.

“…Each year, hundreds of species of birds leave their tropical and subtropical wintering areas for high-latitude summer breeding grounds, returning to lower latitudes at the end of the breeding season (Alerstam et al, 2003;Faaborg et al, 2010). These species are exposed to different parasites in their boreal or temperate breeding areas and in their subtropical or tropical wintering areas, and they potentially could disperse parasites between these areas (Valki unas, 1993;Altizer et al, 2011;Levin et al, 2013;Smith & Ramey, 2015;Levin et al, 2016), particularly because birds retain parasite infections through the annual cycle, and often for many years (e.g. Atkinson et al, 2000).…”

Aim Migrating birds transport their parasites, often over long distances, but little is known about the transfer of these parasites to resident hosts in either the wintering or breeding ranges of the migratory host populations. We investigated the haemosporidian parasite faunas of migratory and resident birds to determine connections among distant parasite faunas, plausibly brought about by migratory host populations. Location Samples were obtained, primarily during or shortly after the local breeding season, throughout the Americas, from the United States through the Caribbean Basin and into northern South America. Methods Infections were identified by PCR and sequencing of parasite DNA in avian blood samples. The analyses were based on c. 4700 infections representing 79 parasite lineages of Plasmodium and Haemoproteus spp. Geographical connections of lineages between regions in the Americas were compared to those in the Euro‐African migration system, where migration distances are longer for many host species and the migrant and resident avifaunas in the wintering areas are phylogenetically more divergent. Results Haemosporidian lineages exhibited considerable variation in distribution in the Americas, and patterns of distribution differ markedly between the Americas and the Euro‐African migration system. In particular, few lineages were recovered from resident species in both temperate and tropical latitudes, particularly in the Euro‐African system, in which a large proportion of lineages were restricted to migrants. Parasite lineages in the Euro‐African system exhibited considerable phylogenetic conservatism in their distributions, that is, a tendency of related lineages to exhibit similar geographical distributions. In contrast, clades of parasites in the Americas displayed more geographical diversity, with four of 12 clades exhibiting all four of the distribution types representing the combinations of resident and migrant host species in both temperate and tropical latitudes. Main conclusions Long‐distance migrants connect communities of avian haemosporidian parasites in breeding and wintering areas with disparate avifaunas and different vector communities. The degree of parasite lineage sharing between migrants and residents in breeding and wintering areas appears to reflect, to a large degree, the taxonomic similarity of migrants to the resident species in both areas.
