  1. Models with the lowest AIC values were considered as best fit (a) and models with Δ AIC < 2 were considered as candidate models (in bold)
  2. Score = body score, people = number of people, city = access to villages, death = recent dog mortality, fauna = interaction with wildlife, dogs = number of dogs, forest = access to forest, sick = recent dog disease, size = area size class, mob = mobility, vet = veterinary assistance
