“…Consistent with our alternative hypothesis, we found that host species was a better predictor of parasite prevalence than environmental heterogeneity (i.e., variation in humidity), a result in agreement with previous findings in forest birds assemblages in insular tropical areas and in subtropical and temperate Old-World warblers Fecchio, Pinheiro, et al, 2017;Scordato & Kardish, 2014). The striking differences in infection rates among our study species may reflect variation in immunity (Bonneaud, Pérez-Tris, Federici, Chastel, & Sorci, 2006), life history (Lutz et al, 2015;Ricklefs, 1992), or behavioral characteristics of host species (Arriero & Møller, 2008;Soares, Escudero, Penha, & Ricklefs, 2016). Most of these factors are unknown or poorly understood for our study species.…”

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.

“…Birds exposed to both saltwater and freshwater habitats have the potential to pick up helminths with specific marine and freshwater transmission pathways and therefore have a richer helminth fauna than those restricted to a single habitat type. Unlike previous studies dealing with avian blood parasites (Figuerola, ; Mendes et al ., ; Yohannes et al ., ; Clark et al ., ; Soares et al ., ), we did not find evidence for a higher helminth species richness in bird species using freshwater habitats compared to species using saltwater habitats. In fact, in the case of trematodes (the most abundant parasites; Fig.…”

“…Along this line, Piersma () hypothesized that the evolution of migration patterns of shorebirds (Charadrii) may be driven by spatial variation in disease risk in different wintering and breeding habitats. This hypothesis has received empirical support from studies showing that arctic‐breeding bird species wintering in saline habitats have lower presence and/or diversity of blood parasites than more southerly breeding species wintering in freshwater habitats (Figuerola, ; Mendes et al ., ; Yohannes et al ., ; Clark et al ., ; Soares et al ., ). However, whether this pattern also applies to parasites other than blood microparasites (haematozoa) remains to be tested.…”

18Aim Habitat use and migration strategies of animals are often associated with spatial 19 variation in parasite pressure, but how they relate to one another is not well understood. 20Here we use a large dataset on helminth species richness of Charadriiform birds to test 21 whether higher habitat diversity and seasonal migration increase parasite richness in 22 avian hosts. 23Location Global. Main conclusions We suggest that birds exploiting diverse habitats and diets are 37 exposed to a more diverse parasite fauna and conclude that distribution patterns and 38 habitat use, rather than migration distance, shape parasite diversity within host

“…In the present study, a relatively low level of haemosporidian infection was found among 36 species which are strongly related to habitat characteristics influence parasite transmission. These factors comprised scarcity of insect vectors, resistance to parasite, sampling time, host and immune system, habitat characterization such as temperature, elevation, and rain-fall and host specifity of parasite ( Bensch et al, 2012 ; Garcia-Longoria et al, 2019 ; Gutierrez-Lopez et al, 2015 ; Rivero de Aguilar et al, 2018 ; Soares et al, 2016 ). Blood collection of migratory birds and some raptors are performed in fall and winter, and low prevalence of haemosporidian parasites may be influenced by seasonal and sampling parameters when suitable vectors are absent.…”

Haemosporidian parasites characterize multi-host and multi-parasite structures which are prevalent among wild bird populations. Here, determination of host records, estimation of the prevalence and diversity of haemosporidian lineages were performed in wild and domestic birds in 11 provinces in Iran. To our knowledge, for the first time in this region, molecular characterization of haemosporidians in migratory water birds, raptors, and domestic birds was carried out: blood or tissue samples were collected from 246 birds belonging to 36 species, 12 families, and 11 orders. The prevalence of Plasmodium , Haemoproteus, and Leucocytozoon were documented as 1.21%, 3.65%, and 0.4%, respectively. Of 36 birds' species inspected in this investigation, 13 individuals of 9 species were parasitized by blood parasites. To our knowledge, five lineages including hANACRE03, hAYTFER01, hAYTFER02, hAQUCYR01, and hSTAL06 were found as un-described lineages, while six known lineages of hLK03, pLK05, lTUSW04, pSW5, hMILANS02, and hHAECOL1 were recorded in hosts within novel geographical regions. Such results are required to fill the gaps in understanding the geographical distribution patterns of wildlife related vector-borne parasites in migratory birds as potential carriers, raptors with high vulnerability, and domestic birds as pet or with economic value.
