“…Turtle doves hosted the highest parasite diversity, being the only species infected with all tested haemosporidian genera and harbouring the highest number of lineages. This is in line with previous studies, which have shown that migratory birds have a higher prevalence and diversity of blood parasites than resident or short-distance migratory species (Figuerola and Green 2000;Jenkins et al 2012;Walther et al 2016;Ciloglu et al 2020b). This could be explained by the fact that residents and short-distance migrants travel between areas that are likely to be within a single transmission area, e.g.…”

“…The identification of current transmission areas and parasite diversity is highly relevant to recognize and understand possible future changes (Ciloglu et al 2020b). As habitat destruction and land-use intensification are among the main reasons causing the sharp decline of turtle doves (Fisher et al 2018), they seem especially prone to be affected by these changes, and thus, parasites could gain importance as threats in the future.…”

“…However, only few studies have presented data on the prevalence and diversity of haemosporidian parasites in closely related bird species. Differences in prevalence between species are associated with several factors and the interactions between those, including life-history traits and ecology of the hosts and vectors, parasite characteristics and environmental conditions, that may affect the activity of vectors and the development of parasites (Sol et al 2000;Gupta et al 2011;Quillfeldt et al 2011;Hellard et al 2016;Chakarov et al 2020;Ciloglu et al 2020b;Ellis et al 2020). Also different behavioural characteristics (e.g.…”

“…Cavity-nesting species may be shielded from vector exposure due to their enclosed surroundings, while open-nesting birds should be more susceptible to flying dipteran vectors. Migratory species, particularly long-distance migrants, are expected to host a higher diversity of parasites (Walther et al 2016;Emmenegger et al 2018;Ciloglu et al 2020b) as they encounter parasites and their vectors in multiple ecosystems each year, whereas residents only encounter parasites in one ecosystem (Møller and Erriyzøe 1998). The European turtle dove Streptopelia turtur (henceforth turtle dove) is the only long-distance migrant among the columbiform birds we tested.…”

Diseases can play a role in species decline. Among them, haemosporidian parasites, vector-transmitted protozoan parasites, are known to constitute a risk for different avian species. However, the magnitude of haemosporidian infection in wild columbiform birds, including strongly decreasing European turtle doves, is largely unknown. We examined the prevalence and diversity of haemosporidian parasites Plasmodium, Leucocytozoon and subgenera Haemoproteus and Parahaemoproteus in six species of the order Columbiformes during breeding season and migration by applying nested PCR, one-step multiplex PCR assay and microscopy. We detected infections in 109 of the 259 screened individuals (42%), including 15 distinct haemosporidian mitochondrial cytochrome b lineages, representing five H. (Haemoproteus), two H. (Parahaemoproteus), five Leucocytozoon and three Plasmodium lineages. Five of these lineages have never been described before. We discriminated between single and mixed infections and determined host species-specific prevalence for each parasite genus. Observed differences among sampled host species are discussed with reference to behavioural characteristics, including nesting and migration strategy. Our results support previous suggestions that migratory birds have a higher prevalence and diversity of blood parasites than resident or short-distance migratory species. A phylogenetic reconstruction provided evidence for H. (Haemoproteus) as well as H. (Parahaemoproteus) infections in columbiform birds. Based on microscopic examination, we quantified parasitemia, indicating the probability of negative effects on the host. This study provides a large-scale baseline description of haemosporidian infections of wild birds belonging to the order Columbiformes sampled in the northern hemisphere. The results enable the monitoring of future changes in parasite transmission areas, distribution and diversity associated with global change, posing a potential risk for declining avian species as the European turtle dove.

“…The most highly sampled host species in our study was Passer hispaniolensis, which showed a prevalence of 44.4%. This level of prevalence is generally similar to the value (55.6%) reported for Turkish populations of this species [54]. However, interestingly, the infection rates between that study and ours differed with respect to levels of parasite genus infections: our Passer hispaniolensis were infected by, in ascending order, Haemoproteus (13.3%), Leucocytozoon (40%) and Plasmodium (46.7%), while in Turkey Plasmodium infections were lacking and Haemoproteus was the main infecting genus.…”

Avian Haemosporidian Diversity on Sardinia: A First General Assessment for the Insular Mediterranean

The Western Palearctic is one of the most investigated regions for avian haemosporidian parasites (Haemoproteus, Plasmodium and Leucocytozoon), yet geographic gaps in our regional knowledge remain. Here, we report the first haemosporidian screening of the breeding birds from Sardinia (the second-largest Mediterranean Island and a biodiversity hotspot), and the first for the insular Mediterranean in general. We examined the occurrence of haemosporidians by amplifying their mtDNA cytb gene in 217 breeding birds, belonging to 32 species. The total prevalence of infected birds was 55.3%, and of the 116 haplotypes recovered, 84 were novel. Despite the high number of novel lineages, phylogenetic analysis did not highlight Sardinia-specific clades; instead, some Sardinian lineages were more closely related to lineages previously recovered from continental Europe. Host-parasite network analysis indicated a specialized host-parasite community. Binomial generalized linear models (GLMs), performed at the community level, suggested an elevational effect on haemosporidian occurrence probability (negative for Haemoproteus; positive for Leucocytozoon) likely due to differences in the abundance of insect vectors at different elevations. Furthermore, a GLM revealed that sedentary birds showed a higher probability of being infected by novel haplotypes and long-distance migrants showed a lower probability of novel haplotype infection. We hypothesize that the high diversity of haemosporidians is linked to the isolation of breeding bird populations on Sardinia. This study adds to the growing knowledge on haemosporidians lineage diversity and distribution in insular environments and presents new insights on potential host-parasite associations.

Migratory behaviour in seasonal environments affects host–pathogen relationships, especially for vector‐transmitted blood parasites of the order Haemosporida. The common starling Sturnus vulgaris is a short‐distance migrant where the north‐eastern European breeding population spend the non‐breeding season in temperate mild western Europe. Despite the high abundance and known susceptibility as a host, blood parasitism in wild starlings has rarely been studied with molecular methods. Here, we monitored haemosporidian parasitism in a Latvian starling population over four breeding seasons. We found a total annual parasite prevalence of 2.7–15.7% caused by four Haemoproteus, three Plasmodium, and one Leucocytozoon cytochrome‐b (cyt‐b) genetic lineages. Herein, seven of these lineages have been recorded for the first time in the common starling as host. Lineage‐specific parasitemia was generally low (Haemoproteus range: 0.008–1.028%, Plasmodium range: 0.002–0.005%, Leucocytozoon range: 0.003–0.004%) indicating chronic infection stages in all parasitised hosts during the breeding season. Additionally, the proportion of leukocytes in peripheral blood was enhanced in infected compared to non‐infected hosts indicating activated immune defence during the chronic infection stage. Finally, 11% (3 out of 27) of individuals had cleared the infection from peripheral blood after one year. Causes for the variability in infection prevalence in common starlings across years, as well as the transmission period during the host annual cycle, are still open for future studies.
