| impact of environmental stressors on the dynamics of disease transmission. | infectious disease within outmigrant juvenile salmon in the columbia river basin is modulated, in part, by abiotic stressors that influence host-susceptibility. through the application of a dose-structured population dynamic model, we show that chemical (both in the river and in the estuary) and in-river (e.g., dams and/or predation) stressors influence host-susceptibility, increasing the mean force of infection (defined as the per capita acquisition rate of infection) by a factor of 2.2 and 1.6 ... | 2005 | 16201666 |
