GIF - Model describing settling patterns.
Fig. 2. Model describing settling patterns of mallard pairs in prairie pothole habitat in eastern North Dakota during May relative to percent of landscape in cropland interacting with temporary/seasonal pond area. Breeding pairs (Y) = 4.46 + 0.72 (pond area) + 0.0016 (% cropland) - 0.0069 (pond area x % cropland).
