The small ruminant parasite Haemonchus contortus is the most widely used parasitic nematode in drug discovery, vaccine development and anthelmintic resistance research. Its remarkable propensity to develop threatens viability of sheep industry many regions world provides a cautionary example effect mass administration control nematodes. phylogenetic position makes it particularly well placed for comparison with free-living Caenorhabditis elegans economically important parasites livestock humans.
In aphids, reproductive mode is generally assumed to be selected for by winter climate. Sexual lineages produce frost-resistant eggs, conferring an advantage in regions with cold winters, while asexual predominate mild winters. However, habitat and resource heterogeneities are known exert a strong influence on sex maintenance might modulate the effect of climate aphid strategies. We carried out hierarchical sampling northern France investigate whether variation Rhopalosiphum padi driven...
Signalling pathways underlie development, behaviour and pathology. To understand patterns in the evolution of signalling pathways, we undertook a comprehensive investigation that control switch between growth developmentally quiescent dauer 24 species nematodes spanning phylum. Our analysis 47 genes across these indicates their interactions are not conserved throughout Nematoda. For example, TGF-β pathway was co-opted into relatively late lineage led to model Caenorhabditis elegans. We show...
Re-examination, using molecular tools, of the diversity haemosporidian parasites (among which agents human malaria are best known) has generally led to rearrangements traditional classifications. In this study, we explored infecting vertebrate species (particularly mammals, birds and reptiles) living in forests Gabon (Central Africa), by analyzing a collection 492 bushmeat samples. We found that samples from five mammalian (four duiker one pangolin species), bird turtle were infected...
Although Plasmodium vivax is responsible for the majority of malaria infections outside Africa, little known about its evolution and pathway to humans. Its closest genetic relative, P. vivax-like, was discovered in African great apes hypothesized have given rise To unravel evolutionary history adaptation different host environments, we generated using long- short-read sequence technologies 2 new vivax-like reference genomes 9 additional genotypes. Analyses show that are highly similar...
Abstract Archaeobotanical evidence suggests that the beginning of cultivation and emergence domesticated sorghum was located in eastern Sudan during fourth millennium BCE. Here, we used a genomic approach, together with archaeobotanical ethnolinguistic data, to refine spatial temporal origin spread cultivated Africa. We built probability map domestication Eastern Africa using data Bayesian models. The Western Ethiopia, perfect concordance recent evidence. Calibrated on archaeological...
Knowledge of population structure, connectivity, and effective size remains limited for many marine apex predators, including the bull shark Carcharhinus leucas. This large-bodied coastal is distributed worldwide in warm temperate tropical waters, uses estuaries rivers as nurseries. As an predator, likely plays a vital ecological role within food webs, but at risk due to inshore habitat degradation various fishing pressures. We investigated shark's global structure demographic history by...
Hybridization, the interbreeding of diagnosably divergent species, is a major focus in evolutionary studies. Eels, both from North America and Europe migrate through Atlantic to mate vast, overlapping area Sargasso Sea. Due lack direct observation, it unknown how these species remain reproductively isolated. The detection inter-species hybrids Iceland suggests on-going gene flow, but few studies date have addressed influence introgression on genetic differentiation eels.
The genetic structure of reservoir populations is a key characteristic in understanding the persistence infectious diseases natural systems. In Highlands Madagascar, where plague has persisted since 1920, black rat, Rattus rattus (L., 1758), sole species acting as disease. Ecological surveys have shown clear correlation between locations plague-persistence area Madagascar (above 800 m elevation) and distribution one endemic vector, flea Synopsyllus fonquerniei , which found exclusively on...
Abstract Parthenogenesis is the main mode of reproduction aphids. Their populations are therefore composed clones whose frequency distribution varies in space and time. Previous population genetic studies on aphids have highlighted existence highly abundant (‘super-clones’), distributed over large geographic areas persisting Whether abundance ‘super-clones’ results from their ecological success or stochastic forces, such as drift migration, an open question. Here, we looked for clines clonal...
Abstract Plasmodium falciparum, the most virulent agent of human malaria, shares a recent common ancestor with gorilla parasite P. praefalciparum. Little is known about other and chimpanzee-infecting species in same ( Laverania ) subgenus as falciparum but none them are capable establishing repeated infection transmission humans. To elucidate underlying mechanisms evolutionary history this subgenus, we have generated multiple genomes from all species. The completeness our dataset allows us...
Abstract Only few studies are available dealing with the relation between winter host density and spatial distribution spring colonization of cereals by host‐alternating cereal aphid species Rhopalosiphum padi Metopolophium dirhodum . Large‐scale in climatically different agroecosystems Germany from 2004 to 2006 revealed for R. M. larger spring/summer populations landscapes higher densities hosts. A small‐scale study was performed wheat fields adjacent a large hedge several typical hosts...
The reconstruction of geographic and demographic scenarios dissemination for invasive pathogens crops is a key step toward improving the management emerging infectious diseases. Nowadays, biological invasions typically uses information both genetic historical to test different hypotheses colonization. Approximate Bayesian Computation framework its recent Random Forest development (ABC-RF) have been successfully used in evolutionary biology decipher multiple histories invasions. Yet, some...

Its closest genetic relative, vivax-like , was discovered in African great apes hypothesized have given rise P. To unravel evolutionary history adaptation we generated using long short read sequence technologies two first reference genomes 9 additional genotypes. Analyses show that are highly similar co-linear within core regions....
