Coyotes and foxes on the rise, one reason why

According to Thomas Newsome of Deakin University and the University of Sydney in Australia, and co-author Aaron Wirsing, an associate professor at the University of Washington’s School of Environmental and Forest Sciences, the rise of secondary predators such as coyotes, jackals and foxes is in large part due to the limits placed on the areas that wolves and dingoes range. He found this to be true in Australia and Europe as well as the United States.

Coyotes and foxes are very adaptable and can be found in suburban settings as well as more open areas. Their population has increased because their main predator, the wolf  and dingo, does not have the ability to range far enough to keep them under control. Wolves need a large area to roam and even though re-location has increased their numbers in some areas, their ability to range is fragmented.

The team plans to study the impact that localization has on the environments where the main predators are the big cats such as jaguars, leopards, lions and tigers.
