Different populations of hosts and parasites experience distinct seasonality in environmental factors, depending on local-scale biotic abiotic factors. This can lead to highly heterogeneous disease outcomes across host ranges. Variable characterizes urogenital schistosomiasis, a neglected tropical caused by parasitic trematodes ( Schistosoma haematobium ). Their intermediate are aquatic Bulinus snails that adapted extreme rainfall seasonality, undergoing prolonged dormancy yearly. While have...
Abstract Aim The role of migratory birds in the spread parasites is poorly known, part because strategies and behaviours potentially affecting transmission are not easy to study. We investigated dynamics infection by blood through annual cycle a long‐distance Nearctic–Neotropical songbird examine this species dispersing between continents. Location Americas. Taxon Grey‐cheeked Thrush ( Catharus minimus , Aves, Passeriformes, Turdidae), Birds. Methods used molecular microscopy screening...
Significance Predicting how ecological interactions among vectors or intermediate hosts of human parasites influence transmission potential to humans remains challenging. Here, we focus on schistosomiasis and demonstrate resource competition snails profoundly alters the link between infected snails, target control, schistosome cercariae, cause infections. We integrated an individual-based bioenergetics model snail dynamics with experiments in artificial waterbodies field observations...
Abstract Animals are frequently coinfected with multiple parasites concurrently, and advances in our sampling of these complex intra-host parasite communities have revealed important ecological impacts on their hosts. However, the spatial distributions environmental determinants coinfection remain infrequently studied. Here, we investigated drivers haemosporidian blood Bicknell's thrush ( Catharus bicknelli ) grey-cheeked minimus ), parapatric sister species that occur across a broad...
Abstract Phylogeographic structure within high-latitude North American birds is likely shaped by a history of isolation in refugia during Pleistocene glaciations. Previous studies individual species have come to diverse conclusions regarding the number and location refugia, but no explicitly tested for biogeographic concordance comparative phylogeographic framework. Here we use hierarchical approximate Bayesian computation analysis mitochondrial DNA sequences from 653 individuals 6 bird that...
Abstract Sexual conflicts often arise between mating partners because each sex tries to maximize its own reproductive success. One major male strategy influence a partner's resource allocation is the transfer of accessory gland proteins. This has been shown occur in simultaneous hermaphrodites as well organisms with separate sexes. Although proteins affect investment resources both and female function, we here specifically focus on investment. In great pond snail, Lymnaea stagnalis ,...
Abstract The latitudinal diversity gradient (LDG) is an established macroecological pattern, but poorly studied in microbial organisms, particularly parasites. In this study, we tested whether latitude, elevation, and host species predicted patterns of prevalence, alpha diversity, community turnover hemosporidian We expected parasite to decrease with alongside the their hosts vectors. Similarly, infection prevalence latitude as vector abundances decrease. Lastly, increase distance be higher...
Abstract Background There is growing recognition that mass drug administration must be complemented with environmental interventions to interrupt schistosomiasis transmission. Accurate mapping of snails and schistosome parasite distribution critical identify foci human exposure prioritize sites for interventions. Methodology We conducted longitudinal surveys schistosomes in 467 waterbodies across 86 villages northwestern Tanzania describe spatial temporal variation snail parasites presence...
Abstract The persistence of a parasite species in an ecological community is determined both by its environmental tolerance and host breadth. relative contribution these niche characteristics to structure challenging parse because also consequence extrinsic factors. We investigated haemosporidian parasites (genera Plasmodium , Leucocytozoon Haemoproteus ) clade avian hosts eastern North America. Species this Catharus thrushes occupy specific elevational bands non‐phylogenetically manner....
In rural northwestern Tanzania, land-use change to increase agricultural water availability has resulted in networks of rain catchment ponds teeming with snails that transmit Schistosoma haematobium, a parasitic worm causing urinary schistosomiasis humans. These aquatic (Bulinus nasutus), however, must endure seasonal droughts transform lush, nutrient-filled habitat barren, parched earth for up seven months yearly. The return the wet season is followed rapidly by reappearance abundant snail...
Abstract As humans continue to alter natural habitats indirectly and directly, species’ geographic ranges may change as they track shifting climate regimes or changing landscapes. Ecological niche models ( ENM s) are frequently used show modern forecast future range changes. These models, however, assume that a species will exhibit conservatism, though this is rarely tested. Here, we examine woodpecker with well‐documented recent expansion assess the effectiveness of predictive by comparing...
