Conservation and ecological implications of the use of space by chilla foxes and free-ranging dogs in a human-dominated landscape in southern Chile

摘要: We investigated whether domestic dogs (Canis lupus familiaris) influenced the use of space by chilla foxes (Lycalopex griseus) in southern Chile and tested hypothesis that interfere with chillas. used scent stations occurrence scats within systematically placed plots to assess habitat both species test were associated Activity data obtained from captures for species, telemetry foxes. Diet was analysed order tease out potential existence exploitation competition.We found that, when active, chillas prairies more native forest less than expected according availability, whereas inactive (during day) preferred forest, only type did not use. The odds dog increased at shorter distance human houses, inverse pattern observed Poisson models showed number visits negatively correlated visits. persecuting and/or killing which also corroborated local people prevent chilla-related poultry losses, supporting idea harass actively.The analysis fed mainly on house food ruminant carcasses hare, hens, mice wild birds, thus suggesting competition is a strong alternative as proximate cause patterns observed. conclude seem constrain carnivores via interference.
