Figure 4From: Characterizing the interface between wild ducks and poultry to evaluate the potential of transmission of avian pathogensCorrespondence between areas predicted as suitable for comb ducks and natural ponds in the study area. The correspondence is estimated by the Cohen's kappa value for three different values of a suitability threshold. This threshold is the value of the predicted probability of presence above which a cell is considered as suitable for the comb ducks by the distribution model. The light grey background indicates the rainy season.Back to article page
