Human ‘super predator’ more terrifying than bears, wolves and Human ‘super predator’ more terrifying than bears, wolves and dogs

Bears, wolves and other large carnivores are frightening beasts but the fear they inspire in their prey pales in comparison to that caused by the human ‘super predator.’ A new study by Western University demonstrates that smaller carnivores, like European badgers, that may be prey to large carnivores, actually perceive humans as far more frightening.

Global carnivore conservation at risk, new report shows

Posted on

A new study confirms that the global conservation of carnivores is at risk. Published in Scientific Reports, the report models future global land conversion and estimates this will lead to significant range loss and conflict with local people in regions critical for the survival of already threatened carnivore species. Organized by researchers from the University […]

Intense competition for reproduction results in violent mass evictions

Posted on

Intense levels of reproductive competition trigger violent evictions of male and female banded mongooses from their family groups, University of Exeter researchers have found. Dominant animals in this species are unable to stop subordinates breeding, leaving them with no resort except to throw them, kicking and screaming, out of the group. Scientists observed a population […]

Animals with larger brains are best problem solvers, study shows

Animals with larger brains are best problem solvers, study shows Why did some species, such as humans and dolphins, evolve large brains relative to the size of their bodies? Why did others, such as blue whales and hippos, evolve to have brains that, compared to their bodies, are relatively puny? It has long been thought […]

* Coexisting with dangerous carnivores

* Coexisting with dangerous carnivores Life is replete with things we don’t like that are good for us. For instance, Brussels sprouts when you were a kid, or common house spiders under your eaves. But with enough information about benefits and risks, combined with the passage of time, we learn to accept and sometimes embrace […]

Endangered foxes on Catalina Island get promising treatment to reduce ear tumors

A team of scientists led by UC Davis found alarming rates of ear mites and ear canal tumors in the endangered foxes. Ear mite treatments they initiated have since dramatically reduced the problem, their studies show. Until recently, endangered foxes on California’s Catalina Island were suffering from one of the highest prevalences of tumors ever […]

Cougars likely to recolonize middle part of U.S. within the next 25 years

A groundbreaking new study shows that cougars, also known as mountain lions and pumas, are likely to recolonize portions of habitat in the middle part of the United States within the next 25 years. It is the first study to show the potential “when and where” of the repopulation of this controversial large predator. The […]

Mating success for the European mink

The European mink (Mustela lutreola) is one of the most endangered mammals in Europe. The reasons for its decline are the destruction of its habitat in riparian areas, competition with the alien American mink and historically, extensive hunting. The European mink is often confused with the American mink (Neovison vison, previously Mustela vison), which has […]

Chronic illness causes less harm when carnivores cooperate

Posted on

Gray wolves in Yellowstone National Park have given researchers the first scientific evidence from wild mammals that living in a group can lessen the impacts of a chronic disease. The research also is one of the first studies to measure the costs of infected non-human individuals of any species on members of their group. Gray […]

* Bird flu: New compound protects 100 percent of ferrets, mice, from H5N1

Medical researchers have developed an antibody which has proven 100 percent protective against the H5N1 virus in two species of animal models. Now a team of investigators from St. Jude Children’s Research Hospital, Stanford University Medical Center, and MacroGenics have developed an antibody which has proven 100 percent protective against the virus in two species […]

Odor that smells like blood: Single component powerful trigger for large carnivores

People find the smell of blood unpleasant, but for predatory animals it means food. When behavioural researchers at LinköpingUniversity in Sweden wanted to find out which substances of blood trigger behavioural reactions, they got some unexpected results. Matthias Laska is professor of zoology, specialising in the sense of smell. For some time his focus has […]

Origins of Arctic fox traced back to Tibet

Posted on

The Arctic fox (Vulpes lagopus) was thought to have evolved in Europe as the ice sheet expanded when a glacial period swept the Earth about 2.6 million years ago. But fossil evidence now suggests that the animal ‘pre-adapted’ to living in the cold and harsh environment on lofty Tibetan terrains. While hiking up and down […]

Study finds recent wolf-dog hybridization in Caucasus region

Posted on

Dog owners in the Caucasus Mountains of Georgia might want to consider penning up their dogs more often: hybridization of wolves with shepherd dogs might be more common, and more recent, than previously thought, according to a recently published study in the Journal of Heredity. Natia Kopaliani, Dr. David Tarkhnishvili, and colleagues from the Institute […]
