Résumé de la publication

Known to have a great economic and ecological importance, the Red river hog is involved in several ecological processes and has also a good zootechnical potential. In Gnanhouizounme community forest, the activity budget of the Red river hog was established and its distribution was modelled. Hence, the photographic trapping method was used to collect its activities from March 2016 to September 2018. A generalized linear Poisson family model and correspondence analysis were used to determine the factors predicting abundance and the most activity during catching hours. A multinomial logistic model was used to assess the relationships between activities and seasons, undergrowth distribution structure, temperature, pressure and group composition. The species distribution was completely random in the forest, as well as to water points, 1 m and 40 m and aggregated when 40 m away from them. At the end of the large rainy season, the adult female vigilance increased than in large dry season where they carried out more of the digging the ground with its snout. Temperature, social behaviour, distance from the camera to the water and bare soils predicted their abundance. It is essential to put the other forest patches under integral protection, study its diet, control its migration corridors and develop a breeding program.
