“…The number of detected infections in each sampling locality ranged from 3 to 55, with two being the lowest lineage richness and 24 the greatest. Detailed information regarding sampling methods and capture licences can be found in Fecchio, Lima, et al (2021a).

“…These parasites are also susceptible to climatic condition themselves, as temperatures can directly affect malaria sporogony within their mosquito vectors (LaPointe et al, 2010). Land conversion also impacts avian malaria ecology, as for example, deforestation can increase Plasmodium prevalence and diversity at the regional scale (Fecchio, Lima, et al, 2021a), whereas localities with denser vegetation and higher water availability have increased avian malaria infection probability at global scales (Fecchio, Clark, et al, 2021). These associations are possibly due to the impact of landscape on ornithophilic mosquito‐bird interactions, due to effects on both vector and bird community composition (Ferraguti et al, 2016; Morante‐Filho et al, 2021), thus affecting Plasmodium transmission (Ferraguti et al, 2018).…”

“…Bird habitat preference also affects Plasmodium probability of infection within the Neotropical region, with bird species from tropical habitats, such as lowland forests being more prone to carry Plasmodium infection (De La Torre & Campião, 2021). Altogether, evidence points to the importance of host functional traits as a driver of Plasmodium diversity and distribution (Fecchio, Lima, et al, 2021a), and also a putative driver of lineage composition in the Atlantic Forest (see delimitation of 'Plasmodium lineages' in Table S1).…”

“…South America supports the highest diversity of avian malarial parasites, with high rates of diversification within tropical and subtropical biomes (Clark, 2018;. However, most studies are concentrated in the Amazon and tropical Andes (McNew et al, 2021;Svensson-Coelho et al, 2013), and information from other biodiversity hotspots, such as the Atlantic Forest, is still poorly explored, especially the association between environment and Plasmodium-bird interactions from a macroecological perspective (Fecchio, Lima, et al, 2021a).…”

1. Disentangling the influence of hosts and environmental factors in parasite community assembly is one of the main challenges in disease ecology. Here we used three approaches to assess the influence of host ecology and evolutionary history, as well as environmental factors on Plasmodium parasite composition within the Atlantic Forest.2. Using sampling data of 2,241 bird individuals captured within the Brazilian Atlantic Forest, we first calculated the functional and phylogenetic host specificity of Plasmodium lineages. We then tested whether host functional or phylogenetic distance predicts Plasmodium taxonomic and phylogenetic beta diversity among host species. Finally, we tested whether temperature, precipitation, landscape dissimilarity and host turnover (taxonomic, functional and phylogenetic) determine Plasmodium taxonomic and phylogenetic turnover among 13 localities within the Atlantic Forest.3. We found that 47% of the parasite lineages were more phylogenetic specialists than expected by chance. In addition, both taxonomic and phylogenetic Plasmodium beta diversity were associated with host phylogenetic distance, indicating that closely related avian species are infected by assemblages composed of more closely related Plasmodium lineages. When comparing Plasmodium lineage community among localities, we found host phylogenetic turnover as the most relevant predictor of Plasmodium taxonomic and phylogenetic turnover.On the other hand, environmental variables explained 23% of Plasmodium taxonomic turnover among localities, suggesting that lineage composition is affected by climate and landscape, especially temperature seasonality.4. Combining all results, our findings suggest host phylogeny is the main driver of the regional Plasmodium assemblages within the Atlantic Forest.
