Wolf spotted in Netherlands for first time in over 100 years

13 March 2015

A wolf has been seen in the Netherlands for the first time in over a century, with footage showing the predator trotting around near a railway track in Noord-Sleen.

Then, that wolf went back to its native Germany; where a truck killed it.

Today, Dutch radio reported that this wolf is coming back to the Netherlands. Later this year, it will be included in the collection of Naturalis museum in Leiden.

Ice age wolf’s bone discovery on Texel island

Translated from Ecomare museum on Texel island in the Netherlands:

Dec 24, 2015 – An exciting discovery on the beach at beach post 12 on Texel. Hiker Els ten Napel found a big bone in the sand. Because she wanted to know what animal it came from, she took it to Ecomare. It proved to be a bone from the Ice Age. Judging from the shape, it is a thigh bone of a wolf. On Texel fossil bones are found regularly, they come from the seabed to the beach. …

From the deep brown color of the wolf’s bone you can see that it probably dates from the last ice age. It would therefore be between 10,000 and 100,000 years old. Wolves were quite common in the last ice age. They hunted many large herbivorous animals that were here then. There were at that time also other carnivorous animals: lions, hyenas, brown bears and humans, but they were a lot rarer. Ecomare has the bones of these predators from the ice age in the collection.

Wolves found to be better at problem-solving task than domesticated dogs

September 16, 2015

(Phys.org)—Monique Udell, a researcher with Oregon State University, has found via experimentation, that domestic dogs appear to have lost some of their problem solving abilities as a result of their long history with humans. In her paper published in the journal Biology Letters, she describes a study she carried out and offers some theories on why she believe domesticated dogs may have lost some of their natural skills.

Udell notes that have long been known to work with people as they go about their lives, in contrast to animals in the wild—one such striking behavior is their tendency to look back at their human companion when faced with a perplexing situation—seemingly asking for help. To learn more about this behavior, Udell enlisted the assistance of ten dogs that live as pets (and their owners), ten that live in shelters, and ten that have been raised by humans.

Each of the animals was presented with a tasty sausage, which they were allowed to sniff, but not eat. Instead, the sausage was placed inside of a with a snap-on lid connected to a short length of rope. To open the , the animals needed to pull on the rope while holding down the container—a task Udell deemed relatively easy for animals as smart as dogs and wolves. Udell conducted the experiments in two ways, one where the animal was left alone with the container, the other where there was a human (their owners) standing close by.

Udell reports that none of the pet dogs was able to open the container and just one of the was able to do so, but eight of the ten wolves succeeded. The presence of a person nearby didn’t help much, the same number of wolves succeeded and one pet did so. She notes that all of the dogs from both groups spent a lot more of their time looking at the person, than did the wolves. Next, Udell allowed a human to offer encouragement to the dogs—doing so increased the success rate of the shelter dogs, four of them opened the container, but still just one pet dog was able to do it.

The experiment is intriguing Udell notes, because all of the dogs and wolves were capable of opening the container, but only the wolves were truly motivated to do so, as demonstrated by a much higher level of persistence—the dogs on the other hand appeared much more ready to ask for help.

Abstract

Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist on such tasks. While dogs’ ‘looking back’ behaviour has been used as an example of socio-cognitive advancement, an alternative explanation is that pet dogs show less persistence on independent tasks more generally.

In this study, pet dogs, shelter dogs and wolves were given up to three opportunities to open a solvable puzzle box: when subjects were with a neutral human caretaker, alone and when encouraged by the human. Wolves were more persistent and more successful on this task than dogs, with 80% average success rate for wolves versus a 5% average success rate for dogs in both the human-in and alone conditions. Dogs showed increased contact with the puzzle box during the encouragement condition, but only a moderate increase in problem-solving success. Social sensitivity appears to play an important role in pet and shelter dogs’ willingness to engage in problem-solving behaviour, which could suggest generalized dependence on, or deference to, human action.

Wolves back in California after almost a century

20 August 2015

Wildlife officials in California say they have photographic evidence of the first gray wolf pack in the state in nearly a century. The California Department of Fish and Wildlife captured images of two black-furred gray wolf adults and five pups in northern California. Other than a lone wolf spotted in 2011, official say the so-called Shasta Pack are the first confirmed wolves in the state since 1924. Trail cameras recorded individual images of the two adults, as well as one photo of the pups, which appear to be a few months old. Wolves used to be seen regularly in California, but they are now considered endangered by both the state and federal government.

Fears hunters may kill newly discovered canine group

A wolf pack has been spotted in California for the first time in nearly a century.

Two adults and five pups have been confirmed in southeastern Siskiyou County. Local ranchers tending to their herds told authorities they had spotted the animals.

State and federal authorities subsequently confirmed the sightings after a remote camera captured photos of the pack.

The state’s grey wolf population became extinct in 1924. They were named the Shasta pack, after the nearby Mount Shasta.

Karen Kovacs, from the California Department of Fish and Wildlife, said she was stunned by the news of the wolves’ return. She believes they have most likely migrated from Oregon’s north-eastern corner.

It is hoped DNA tests might be able to give a more accurate understanding of the animals’ backgrounds.

The canines are protected by federal and state endangered species legislation but Amaroq Weiss, from the Centre for Biological Diversity, said local conservationists are concerned the wolves could still fall victim to hunters as hunting season gets underway in the area.
