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.
A study conducted by Vladimire Dinets, UT Assistant Professor of Psychology at the University of Tennessee, Knoxville, and Benjamin Eligulashvili, an Israel-based zoologist, seems to imply that these two enemies may have joined together for survival in the harsh Israeli desert.
Striped Hyenas were observed in the middle of grey wolf packs as they traveled together through a maze of canyons in the southern part of the Negev desert.
Why would they do this? The theory is that the hyenas have a better sense of smell and the ability to locate carrion miles away. They can also dig and crack bones better than wolves. The wolves are more agile and can bring down large game. Together they both have a greater chance of survival.
What is not known is if this is a common occurrence that has not been observed before, or an unusual event.
What is nice about their unity, as Dinets commented, it is an example for humans about overcoming differences and learning to get along.
It is always refreshing to learn more about the behavior of wild animals and studies like this make you wonder how much more there is to learn.
