Final answer:
This is an example of Organismal Ecology, as the wildlife biologist is studying the effects of mange on urban San Joaquin Kit Foxes and hypothesizes that domestic pet dogs are spreading it to the foxes.
Step-by-step explanation:
This is an example of Organismal Ecology. Organismal ecologists study the adaptations that enable individuals to live in specific habitats. In this case, the wildlife biologist is studying how the illness called 'mange' affects urban San Joaquin Kit Foxes and hypothesizes that domestic pet dogs are spreading it to the foxes. This research focuses on the interactions between the Kit Foxes and the microscopic mite causing the illness.
