Vector and host communities, as well as habitat characteristics, may have important but different impacts on the prevalence, richness and evenness of vector-borne parasites. 2. We investigated the relative importance of (1) the mosquito community composition, (2) the vertebrate community composition and (3) landscape characteristics on the prevalence, richness and evenness of avian Plasmodium. We hypothesized that parasite prevalence will be more affected by vector-related parameters, while host parameters should be also important to explain Plasmodium richness and evenness. 3. We sampled 2,588 wild house sparrows (Passer domesticus) and 340,829 mosquitoes, and we performed vertebrate censuses at 45 localities in the Southwest of Spain. These localities included urban, rural and natural landscapes that were characterized by several habitat variables. 4. Twelve Plasmodium lineages were identified in house sparrows corresponding to three major clades. Variation partitioning showed that landscape characteristics explained the highest fraction of variation in all response variables (21.0%-44.8%). Plasmodium prevalence was in addition explained by vector-related variables (5.4%) and its interaction with landscape (10.2%). Parasite richness and evenness were mostly explained by vertebrate community-related variables. 5. The structuring role of landscape characteristics in vector and host communities was a key factor in determining parasite prevalence, richness and evenness, although the role of each factor differed according to the parasite parameters studied. These results show that the biotic and abiotic contexts are important to explain the transmission dynamics of mosquito-borne pathogens in the wild. specialized bird and mammal community environmental predictors mosquito community composition NDVI Plasmodium vector-borne disease water reservoir 052 080 87 3 727-740 2018 0021-8790 https://www.documentation.ird.fr/hor/fdi:010072748 10.1111/1365-2656.12805 0021-8790 [F B010072748] https://www.documentation.ird.fr/hor/fdi:010072748 https://www.documentation.ird.fr/intranet/publi/2018/05/010072748.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-06-01 2018-06-01 fdi:010072748 fre
