how to use population abundance data for a zero prevalence study which is true about the incidence of zero abundance what is the relationship between population abundance and percentage mortality? how are percentage abundances related to mortality what percent mortality due to disease is the same for a predator prevalence of disease is a useful variable how to predict prevalence percentage mortality from disease on host populations how does low prevalence affect population abundance prevalence of disease what is zero abundance in predation how to use prevalence data to predict population abundance percentage mortality from predator effects of predation and disease on the host population effect of population abundance on population why is % mortality from predators variable how is incidence of disease affected by predation what percentage of mortality is due to predation of the host how to determine a zero in population abundance can prevalence be used to calculate population abundance in a population
