Journal ArticleDOI
Evolution of virulence in emerging epidemics.
TL;DR: It is shown that the observed transient selection for virulence and horizontal transmission can be fully explained within the framework of evolutionary epidemiology theory, and is a key step towards a predictive theory for the evolution of virulence in emerging infectious diseases.
Journal ArticleDOI
Mixed infections and the evolution of virulence: effects of resource competition, parasite plasticity, and impaired host immunity.
Marc Choisy,Jacobus C. de Roode +1 more
TL;DR: Developing and using a two‐parasite epidemiological model with recovery, it is confirmed that within‐host competition for resources selects for higher virulence, however, parasite phenotypic plasticity and impaired host immunity can select for lower virulence.
Journal ArticleDOI
Evolution of trophic transmission in parasites: why add intermediate hosts?
TL;DR: It is argued that under particular circumstances, adding a second host to a single‐host life cycle is likely to enhance transmission, and an optimality model is used to explore this idea in relation to dispersal strategies known among free‐living species, especially animal dispersal.
Journal ArticleDOI
Harvesting can increase severity of wildlife disease epidemics
Marc Choisy,Pejman Rohani +1 more
TL;DR: It is shown that the interaction between density dependent effects and harvesting can substantially increase both disease prevalence and the absolute number of infectious individuals, which clearly increases the risk of cross-species disease transmission into domestic and livestock populations.
Journal ArticleDOI
Larval habitat segregation between the molecular forms of the mosquito Anopheles gambiae in a rice field area of Burkina Faso, West Africa.
TL;DR: Evidence is presented for habitat segregation between the two molecular forms in and around irrigated rice fields located within the humid savannahs of western Burkina Faso to support hypotheses about larval habitat segregation and confirm the suggestion that the forms have different larval habitats requirements.
