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.

The Himalayan wolf is probably the oldest and rarest species of wolves in the world

The Himalayan wolf is on the critically endangered list because they are so rare. Their existence and plight have become publicized by the efforts of an international research team led by Madhu Chetri, a graduate student at the Hedmark University of Applied Sciences in Norway. He has studied the wolf in the largest protected area of Nepal.

The Himalayan wolf looks quite a bit different then its European cousins. They are smaller in size, have a longer muzzle and shorter, stumpy legs. They are also marked differently with white around their throat, chest and belly and the inner parts of their legs. They also have a wooly coat.

To me they look more like our modern Husky breeds, especially the Malamute and Siberian Husky. Siberian Huskies have been known to have an occasional wooly coat.

The researches feel that the Himalayan wolf is a separate branch of the wolf-dog family tree, making it especially rare.

As is the case with most wolves, the local farmers, ranchers and livestock owners hunted and killed as many wolves as they could, believing that they are a threat to their domestic livestock.

Hopefully, the researchers will be able to save this rare and unusual member of the wolf family.
