“…This result concurs with prevalence reported for the Neotropics (Latta and Ricklefs 2010, Ricklefs et al 2011, Lacorte et al 2013, Marzal et al 2015. In contrast, a previous large-scale study (1487 birds screened) across Neotropical highlands in Colombia (González et al 2015) found an overall prevalence of 10%, although this study did not screen for Leucocytozoon infections and this genus was the most common in our study (see below). However, the prevalence in our study was similar to that reported in another small-scale study in the Chingaza Park, Colombia at elevations above 3000 m asl, which included Leucocytozoon in the screening, and reported an overall haemosporidian prevalence of 27.9% (Rodríguez et al 2009).…”

“…The lineages detected in this study are found in several host species, and they have been reported elsewhere suggesting that they could have been introduced easily from migrating bird species. In this study we only captured two individuals of the migrating species Vermivora peregrina, resident of North America, one of which was infected with the previously reported Haemoproteus witti lineage PA182 (González et al 2015). The same PA182 sequence was detected in Metallura tyrianthina in our study, a species of hummingbird that is widespread across northern South America (del Hoyo et al 1999).…”

“…2). The most abundant lineage identified was 99% identical (1 or 2 bp different) to the previously described Haemoproteus lineage DICER01 (González et al 2015), accounting for 22.7% of infections, all of which were found in the same host species, the SNSM endemic A. melanocephalus. The probability of finding the DICER01-similar lineage always infecting A. melanocephalus just by chance was 0.0082; thus, it is likely that there is a specialist association between the DICER01-similar lineage and the bird species A. melanocephalus.…”

“…Another interesting pattern is that continental South America harbours the largest number of lineages of both Plasmodium and Haemoproteus (Clark et al 2014). However, much of the research that has been done is restricted to European and North American passeriform communities, and only a few sites have been sampled in continental Neotropics (Lacorte et al 2013, Clark et al 2014, González et al 2015, Marzal et al 2015. Thus, species richness for continental Neotropics is likely to be underestimated.…”

, an isolated coastal massif in northern Colombia that contains a large number of biomes and that is experiencing high rates of habitat loss. We sampled birds from 25 species at 2 different altitudes (1640 and 2100 m asl) and determined avian haemosporidian infection by polymerase chain reaction and sequencing a portion of the cytochrome b (cyt b) gene of the parasite. From the sampled birds, 32.1% were infected by at least 1 of 12 unique cyt b lineages of haemosporidian genera: Plasmodium, Leucocytozoon, Haemoproteus, and subgenus Parahaemoproteus. We found a higher prevalence of avian haemosporidians at low altitudes (1640 m asl). All endemic bird species we sampled had at least one individual infected with avian haemosporidians. We also found evidence of higher overall prevalence among endemic rather than nonendemic birds, suggesting higher susceptibility in endemic birds. Overall, our findings suggest a high haemosporidian species richness in the bird community of the SNSM. Considering the rate of habitat loss that this area is experiencing, it is important to understand how avian haemosporidians affect bird populations; furthermore, more exhaustive sampling is required to fully comprehend the extent of avian haemosporidian infection in the area.

The major histocompatibility complex (MHC) is a genetic region in jawed vertebrates that contains key genes involved in the immune response. Associations between the MHC and avian malaria infections in wild birds have been observed and mainly explored in the Northern Hemisphere, while a general lack of information remains in the Southern Hemisphere. Here, we investigated the associations between the MHC genes and infections with Plasmodium and Haemoproteus blood parasites along a latitudinal gradient in South America. We sampled 93 rufous‐collared sparrows (Zonotrichia capensis) individuals from four countries, Colombia, Ecuador, Peru, and Chile, and estimated MHC‐I and MHC‐II allele diversity. We detected between 1–4 (MHC‐I) and 1–6 (MHC‐II) amino acidic alleles per individual, with signs of positive selection. We obtained generalized additive mixed models to explore the associations between MHC‐I and MHC‐II diversity and latitude. We also explored the relationship between infection status and latitude/biome. We found a non‐linear association between the MHC‐II amino acidic allele diversity and latitude. Individuals from north Chile presented a lower MHC genetic diversity than those from other locations. We also found an association between deserts and xeric shrublands and a lower prevalence of Haemoproteus parasites. Our results support a lower MHC genetic in arid or semi‐arid habitats in the region with the lower prevalence of Haemoproteus parasites.

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.
