As states around the country move to stiffen punishments for animal cruelty, Michigan State University researchers have found a correlation between the types of animal abuse committed and the perpetrator's relationship to an animal and its owner.
A research team led by the Max Planck Institute for Evolutionary Anthropology and the German Centre for Integrative Biodiversity Research investigated whether chimpanzee behavioral diversity is reduced when there is high human impact on their habitats. By comparing sets of chimpanzee behaviors across a large number of social groups exposed to different levels of human disturbance, the scientists found a reduction in behavioral diversity when human impact was high. The results of the study were published this week in the journal Science.
Using a series of well-designed experiments in Mozambique's Gorongosa National Park, a Princeton-led research team confirmed each step in a trophic cascade between the elimination of predators (including leopards, African wild dogs, and hyenas) and growth of local plants. They demonstrated that the fear of predators alone can drive change in herbivore behaviors in large-mammal ecosystems.
Since the arrival of British settlers over 230 years ago, most Australians have assumed dingoes are a breed of wild dog. But 20 leading researchers have confirmed in a new study that the dingo is actually a unique, Australian species in its own right.
If it walks like a duck (or a goose or a swan), it can find food in mud without seeing or smelling it. These waterfowl bills are covered in skin that's a lot like the sensitive skin on the palms of our hands, and it can feel food in mud and murky water. Slav Bagriantsev, Eve Schneider, and Evan Anderson at Yale University are researching duck skin to learn more about how our sense of touch works.
Researchers at the University of Colorado Boulder study fast-growing python hearts, which could provide insights to aid those with diseased heart growth. Their latest work reveals ways to study python heart cells.
Researchers at the University of Illinois College of Medicine find that TRPM8, long ago identified as a cold-temperature sensor, regulates aggressive and hypersexual behavior in response to testosterone.
Giraffes that live close to densely populated towns have larger home ranges than giraffes that live far from towns, suggesting that the giraffes in human-impacted areas need to travel longer distances -- and expend more energy -- to obtain critical resources.
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.
Hesperos reports the successful testing of multi-organ 'human-on-a-chip' models to recapitulate the 28-day experiments typically used in animals to evaluate the systemic toxicity of drug and cosmetic compounds. The work is published in Advanced Functional Materials.
