DNA assay aids in identifying and protecting North American wolves, coyotes

Forensics specialists can use a commercial assay targeting mitochondrial DNA to accurately discriminate between wolf, coyote and dog species. The genetic information could aid authorities in prosecuting hunting jurisdiction violations and preserving protected species.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/VMwdFBWLL40View the source article

Dogs may not return their owners' good deeds

Domestic dogs show many adaptations to living closely with humans, but they do not seem to reciprocate food-giving according to a new study.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/kYugw-DKVh0View the source article

Restless nights: Shelter housed dogs need days to adapt to new surroundings

Every year, thousands of dogs end up in a shelter in the Netherlands. Experts expect an increase in this number in the upcoming period, when people go back to the office after working from home during the corona crisis. Despite the good care of staff and volunteers, the shelter can be a turbulent experience for dogs. Researchers investigated if dogs can adapt to their new environment based on their nocturnal activity.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/dOftsAYYLHUV

You can snuggle wolf pups all you want, they still won't 'get' you quite like your dog

You know your dog gets your gist when you point and say 'go find the ball' and he scampers right to it. This knack for understanding human gestures may seem unremarkable, but it's a complex cognitive ability that is rare in the animal kingdom. New research comparing dog puppies to human-reared wolf pups offers some clues to how dogs' unusual people-reading skills came to be.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/UQe-RbCuC84View the source article

Hunting and hidden deaths led to 30% reduction in WI wolf population

About 100 additional wolves died over the winter in Wisconsin as a result of the delisting of grey wolves under the Endangered Species Act, alongside the 218 wolves killed by licensed hunters during Wisconsin's first public wolf hunt, according to new research. A majority of these additional, uncounted deaths are due to cryptic poaching, where poachers hide evidence of illegal killings.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/_absHMbiaC0View the source article

Antelope's fate shrouded by social, political forces

The story of efforts to conserve the endangered oribi in South Africa represent a diaspora of issues as varied as the people who live there.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/l1CmMKjOdCw View the source article

Puppies are wired to communicate with people

Dogs may have earned the title 'man's best friend' because of how good they are at interacting with people. Those social skills may be present shortly after birth rather than learned, a new study suggests.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/UjuS-Ke25u8 View the source article

Gene that causes canine hereditary deafness in puppies

Researchers have been the first to determine the cause for the nonsyndromic early-onset hereditary canine hearing loss in Rottweilers. The gene defect was identified in a gene relevant to the sense of hearing. The study can also promote the understanding of mechanisms of hearing loss in human.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/z6W3DAmKNlM View the source article

Surveillance turns up new coronavirus threat to humans

Researchers have discovered a new coronavirus, found in a child with pneumonia in Malaysia in 2018, that appears to have jumped from dog to human. If confirmed as a pathogen, the novel canine-like coronavirus could represent the eighth unique coronavirus known to cause disease in humans. The discovery also suggests coronaviruses are being transmitted from animals to humans more commonly than was previously thought.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/v9gOZSDq3Cg Vie

Petting therapy dogs enhances thinking skills of stressed college students

Programs exclusively focused on petting therapy dogs improved stressed-out students' thinking and planning skills more effectively than programs that included traditional stress-management information, according to new research.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/emGRWE-Sczo View the source article

Long-term stress in dogs linked to the owner-dog relationship

The relationship a dog has with its owner is related to its stress level. This is the conclusion of a newly published study. The results also suggest that the link between stress and the owner's personality traits differs between dog breeds.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/2p8S2tKkMRo View the source article

The African wild dog: An ambassador for the world's largest terrestrial conservation area

The world's largest terrestrial conservation area is located in southern Africa and covers 520,000 square kilometers spanning five countries. A study now shows that the endangered African wild dog mostly remains within the boundaries of the Kavango-Zambezi Transfrontier Conservation Area (KAZA) when dispersing, thus highlighting the relevance of such a large-scale conservation initiative for maintaining key wildlife corridors of threatened species.http://feeds.feedburner.com/~r/sciencedaily/plan

Dogs' aggressive behavior towards humans is often caused by fear

A study encompassing some 9,000 dogs demonstrated that fearfulness, age, breed, the company of other members of the same species and the owner's previous experience of dogs were associated with aggressive behavior towards humans. The findings can potentially provide tools for understanding and preventing aggressive behavior.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/L1mE5s1yoW4 View the source article

A gene finding links severe canine juvenile epilepsy to mitochondrial dysfunction

Researchers found a cause for severe epilepsy resulting in death in Parson Russell Terrier puppies at a few months of age. A change in the PITRM1 gene can lead to a dysfunction of mitochondria, the cellular energy pumps. Concurrently, amyloid-beta accumulation and widespread neurodegeneration associated with Alzheimer's disease were identified in the puppies' brains. Changes to the PITRM1 gene in humans also cause a severe but slowly progressing brain disease.http://feeds.feedburner.com/~r/scien

Mystery canine illness identified: Animal coronavirus

Shift in diet allowed gray wolves to survive ice-age mass extinction

Gray wolves are among the largest predators to have survived the extinction at the end of the last ice age. A new study analysing teeth and bones shows that the wolves may have survived by adapting their diet over thousands of years --- from a primary reliance on horses during the Pleistocene, to caribou and moose today.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/UOckykQqSqU View the source article

Dogs act jealously even when they don't see their rival

Dogs are one of humanity's most-beloved animal companions. They share our homes and seem to reciprocate our affections. But could this emotional bond extend into feelings of jealousy? To help answer that question, a team of researchers gauged the reactions of a group of dogs when their owners appeared to shower attention on a perceived rival.http://feeds.feedburner.com/~r/sciencedaily/plants_animals/dogs/~4/J4s4NVt8ttE View the source article
