Abstract: Identifying the ecological factors that shape parasite distributions remains a central goal in disease ecology. These factors include dispersal capability, environmental filters and geographic distance. Using 520 haemosporidian parasite genetic lineages recovered from 7,534 birds sampled across tropical and temperate South America, we tested (a) the latitudinal diversity gradient hypothesis and (b) the distance–decay relationship (decreasing proportion of shared species between communities with increasing geog… Show more

“…Our hierarchical linear regression clearly demonstrates a positive relationship between parasite diversity and Latitude across New World bird communities, which is in opposition with the LDG hypothesis and contrasts with previous studies showing that species richness increases towards the equator in some parasitic and pathogenic organisms (Fecchio, Bell, et al, ; Guernier, Hochberg, & Guégan, ; Nunn, Altizer, Sechrest, & Cunningham, ; Rohde & Heap, ). Whether or not pathogens consistently obey this macroecological phenomenon, as observed for a multitude of free‐living organisms, has received conflicting support and a growing body of evidence supports a lack of an effect of latitude on species richness, abundance, diversity or prevalence for parasitic organisms (Clark, ; Kamiya et al, ; Poulin, ; Rohde & Heap, ).…”

“…The highest probability of a bird being infected with Leucocytozoon was consistently found in regions with cooler summers and towards the pole, demonstrating that high temperature appears to be an important environmental barrier for Leucocytozoon distribution. Previous studies have shown that climate has little or no influence on the diversity and distributions of two related genera ( Plasmodium and Haemoproteus ) in both Nearctic (Ellis et al, ) and Neotropical birds (Fecchio, Bell, et al, ), whereas temperature explained haemosporidian prevalence (including Leucocytozoon ) in Arctic birds (Oakgrove et al, ). Although Plasmodium prevalence and distribution are constrained by low temperature due to thermal limits on parasite development within mosquito vectors (LaPointe, Goff, & Atkinson, ), Leucocytozoon might be constrained by high temperature (Fecchio et al, ).…”

“…For example, three specialist lineages-MONCAC03, MONFAI02, and MONMER02showed signals of co-speciation and have co-diversified with their endemic hosts Montecincla cachinnans, Montecincla fairbanki, and Montecincla meridionalis, respectively (see electronic supplementary material, figure S5). Our results further strengthen the patterns of local diversification of avian haemosporidians observed in other tropical bird communities [49,51]. Broadly, empirical data from other host-parasite systems suggest that parasites tend to be host-specialists in species-rich communities [63].…”

“…Although the significant difference between trematode component communities was revealed in different lakes, these differences are rather due to the uneven distribution of snail hosts across the waterbodies. Accordingly, this illustrates a clear structure in the trematode communities that indicate distinctive groups of trematode communities in the different snail species, similar to other host-parasite systems 47 . It is, therefore, the composition of snail host populations that shapes the trematode community structure in lakes of the River Ruhr.…”
