Who should Fido fear? Depends on relationship

As states around the country move to stiffen punishments for animal cruelty, researchers have found a correlation between the types of animal abuse committed and the perpetrator's relationship to an animal and its owner.

Wolves lead, dogs follow -- And both cooperate with humans

The statement is a bold one, especially as wolves have received a lot of negative attention in recent years. A recent study conducted by behavioral researchers, however, shows that dogs and wolves both work equally well with humans, albeit in different ways. The allegedly unequal brothers are thus much more similar than often assumed.

Hungry moose more tolerant of wolves' presence

Research in western Wyoming shows that close proximity of wolves does cause moose to move, but not enough to drive them from their preferred habitats -- especially late in the winter.

Debate on predator-prey relationships

Experts have shed new light on the relationship between predators and their prey after studying how elk responded to the risk posed by grey wolves in an American national park.

Disrupting wolf movement may be more effective at protecting caribou

Researchers used motion-triggered cameras to capture photographs of wolves, caribou, and other wildlife species in the Canadian Oil Sands to study the habitat use patterns of these animals and test management strategies aimed at reducing the impacts of the linear developments on caribou.

Likelihood of tick bite to cause red meat allergy could be higher than previously thought

The original hypothesis was that humans developed the red meat allergy after being exposed to the alpha-gal protein through a tick that had fed previously on a small mammal. But new data suggests ticks can induce this immune response without requiring the mammal blood meal, which likely means the risk of each bite potentially leading to the allergy is higher than doctors had anticipated.

Good dog? Bad dog? Their personalities can change

When dog-parents spend extra time scratching their dogs' bellies, take their dogs out for long walks and games of fetch, or even when they feel constant frustration over their dogs' naughty chewing habits, they are gradually shaping their dogs' personalities.

Foxes were domesticated by humans in the Bronze Age

In the northeast of the Iberian Peninsula, between the third and second millennium BC, a widespread funeral practice consisted in burying humans with animals. Scientists have discovered that both foxes and dogs were domesticated, as their diet was similar to that of their owners.

Dog burial as common ritual in Neolithic populations of north-eastern Iberian Peninsula

Coinciding with the Pit Grave culture (4200-3600 years before our era), coming from Southern Europe, the Neolithic communities of the north-eastern Iberian Peninsula started a ceremonial activity related to the sacrifice and burial of dogs. The high amount of cases that are recorded in Catalonia suggests it was a general practice and it proves the tight relationship between humans and these animals, which, apart from being buried next to them, were fed a similar diet to humans'.

Cancer comparison across species highlights new drug targets

Cancer genes in mucosal melanoma, a rare and poorly understood subtype of melanoma, have been compared in humans, dogs and horses for the first time. Researchers sequenced the genomes of the same cancer across different species to pinpoint key cancer genes. The results give insights into how cancer evolves across the tree of life and could guide the development of new therapies.

Overlapping genomic regions underlie canine fearfulness and human mental disorders

Researchers have identified two novel anxiety-related genomic regions in German Shepherd dogs. The region associated with fearfulness corresponds with the locus of human chromosome 18, which is associated with various psychiatric disorders, while the region associated with noise sensitivity includes several genes related to human and canine behavior and mental disorders.

11,500-year-old animal bones in Jordan suggest early dogs helped humans hunt

11,500 years ago in what is now northeast Jordan, people began to live alongside dogs and may also have used them for hunting, a new study shows. The archaeologists suggest that the introduction of dogs as hunting aids may explain the dramatic increase of hares and other small prey in the archaeological remains at the site.

Bulldogs' screw tails linked to human genetic disease

With their small size, stubby faces and wide-set eyes, bulldogs, French bulldogs and Boston terriers are among the most popular of domestic dog breeds. Now researchers have found the genetic basis for these dogs' appearance, and linked it to a rare inherited syndrome in humans.
