Understanding the transmission of bacterial agents of sapronotic diseases using an ecosystem-based approach: A first spatially realistic metacommunity model
Fig 5
Relative sensitivity to biomass-related parameters.
Panel (A) represents the relative contribution of fish and macroinvertebrate biomass types; the blue curve shows the dynamics when both biomass types are present, the red curve is that with absence of fish and that in cyan the dynamics observed in absence of macroinvertebrates. Parameters for illustration are: σA = 2 and σF = 4. Panel (B) illustrates the effect of reduction by 10% of the bacilli attachment rates on macroinvertebrate ξ (purple curve), panel (C) the effect of the same reduction by 10% on macroinvertebrate-associated bacilli growth rates θ (brown curve), and panel (D) the effect of the same reduction by 10% on bacilli release rate (saprophytism) from macroinvertebrate death σA (green curve), on the abundance of the lower catchment area free-living bacteria. In each subfigure, the blue curve shows the dynamics given with initial values.
