Impact of Red Fox Predation on the Sex Ratio of Prairie Mallards

Figure 14: Plots Depicting the Simulated Effect of Reduced Predator Populations on Mallard Populations

Fig 14. Plots depicting the simulated effect of reduced predator popultaions, no hunting and expanded mallard population on the sex ratio of prairie mallard populations in pristine times. The lines correspond to average male mallard populations of (A) 200,000, (B) 400,000, (C) 800,000, and (D) 1,600,000.
