Descripción
The host range of a pathogen is central to predicting disease risk. Most analyses of disease risk emphasise evolutionary causation, rely on reductionist approaches, or are theoretical. Focus on specialist associations with narrow host ranges has overshadowed the widespread phenomenon of generalism. Ecological evidence from multi-host ? multi-pathogen systems, where heterogeneous communities offer pathogens changing conditions for transmission, is scant. Current hypotheses for disease risk ? host diversity relationships are contradictory, with high host diversity predicting both increases and decreases in disease risk. Here we demonstrate how plant viruses with different host ranges respond to dramatically restructured communities in agricultural ecosystems. We show that incidence-diversity relationships are scale and habitat dependent. Host range, host life cycle, and co-infection were important contributors to predicting disease risk. Infection characteristics of broad host-range viruses indicated habitat-specific host specialisation, i.e. facultative generalism. Findings suggest consistency in land-use practices promote functional compartmentalisation of transmission dynamics among distinct communities.
