Independent and Competing Disease Risks: Implications for Host Populations in Variable Environments
2006
American Naturalist
Disease models usually assume disease to act independently of other mortality-and morbidity-causing factors. Alternatively, disease may function as a competing risk factor, for example, killing already moribund hosts. Using tuberculosis (TB) in African buffalo as a model system, we explore consequences of competing or independent disease effects for host population dynamics. We include scenarios with density-dependent and density-independent effects of environmental variation, exemplified by
