Melanism is a common colour polymorphism in carnivores, and may have adaptive relevance in certain ecological scenarios. This coat colour variation is present in Arabian Wolves Canis lupus arabs, a widely distributed species in the Arabian Peninsula, especially in western Highlands of Saudi Arabia. Data collection involved field surveys conducted between 2010 and 2017 including active searches for black wolf carcasses, records of live animals encountered during field surveys, and by using >100 camera traps. Niche models were generated for non-melanistic and melanistic wolves based on environmental predictors aiming to discover geographic patterns of distinct phenotypes distribution in this area. In this study, melanistic wolves were recorded at 12 locations from western highlands ranges. Niche model predicts suitability for melanistic and non-melanistic wolves mainly in western highlands and found that melanistic wolves were encountered in regions where moisture is high, predicting a close relationship between humidity and the presence of black animals.
