Scientists analyzed coyote and red fox fur trapping records to show the 'wolf effect' favoring red foxes in wolf presence and coyotes elsewhere. The balance between species shifts dramatically with wolf abundance, providing insights for Australian wildlife management.
Scientists have visualized the inactive X chromosome in intact cells for the first time, revealing its unique substructural organization. This breakthrough could help understand gene activity and inheritance patterns, with potential implications for diagnosing and treating X-chromosome-linked diseases.
Researchers found that fur coats and down feathers derive their insulating power from an optical mechanism involving the scattering of infrared light. This discovery could lead to improved building insulation and the development of new types of ultrathin insulation.
The discovery of Megaconus mammaliaformis sheds light on the evolution of modern mammals, revealing a 165-million-year-old proto-mammal with hair and fur. The fossil, found in Inner Mongolia, China, provides evidence that key biological functions related to skin and integument evolved before the rise of modern mammals.
William Beaumont's 238 experiments with Alexis St. Martin, a fur trader who suffered an accidental gunshot wound in 1822, form the basis of early knowledge on digestion. He discovered hydrochloric acid and proposed the existence of pepsin, a key digestive chemical.
A new study in the Bering Sea found that predator-prey relationships prioritize prey density over total biomass. This discovery challenges conventional management methods, which often rely on biomass data.
An international team of scientists has discovered a new species of slow loris in Borneo, recognizing four existing species as distinct from previously considered subspecies. The discovery highlights the need for urgent conservation efforts due to human activity threats and the pet trade.
A new study suggests that climate change could impact Antarctic fur seals in their first few months of life by altering energy budgets. The research found that as pups get older, less energy is available for growth and development.
A new study by University of Miami researchers provides insights into the physical conditions and biological factors underlying white shark attacks on Cape fur seals. The study found that sharks use stealth and ambush tactics to stalk their prey, while seals employ unique techniques to detect and evade predators.
The Henry M. Jackson Foundation has awarded fellowships to three USU students, including Jeremy Gilbreath, Camden Elliott, and Kerry Whittaker, to investigate the structure and function of bacterial pathogens, Loss of Control Eating Disorder, and the relationship between positive psychosocial factors and cardiovascular health
Researchers at UAB discover that Salmonella enterica uses Fur protein to modulate gene expression based on iron levels, adapting to each stage of the infection process. This control allows the bacterium to invade the epithelium and then avoid unnecessary energy expenditure.
Researchers found a link between the fur trade routes and modern-day patterns of tuberculosis. The particular TB strain was introduced to remote Aboriginal populations in Canada by French Canadian fur traders during this period.
A study by Stanford scientists found a specific TB strain was unintentionally spread among indigenous peoples of western Canada, leading to epidemics decades later. Poor living conditions and malnutrition on reservations contributed to the outbreak.
A new species of snub-nosed monkey, Rhinopithecus strykeri, has been discovered in Northern Myanmar with distinctive characteristics. The species is critically endangered due to increasing hunting pressure from logging road construction by Chinese companies, threatening its survival.
Researchers analyzed mink carcasses to determine diet and movement patterns, revealing a reliance on seafood and coastal habitats. The findings will aid in the eradication of this invasive species from native ecosystems.
Scientists developed a new method to measure ocean CO2 uptake, mapping it for the entire North Atlantic. This improvement enables more accurate predictions of global climate change and potentially leads to an 'early warning system' for climate change signals.
Researchers compare DNA from museum specimens to that of living canids, revealing the Falklands wolf's closest living relative is the maned wolf. The team also finds a common ancestor at least 70,000 years ago, suggesting the wolves arrived in the islands before humans entered the New World.
Research by Dr Elizabeth Barry reveals how 18th century obituaries popularized the concept of celebrity, shifting attention from historically significant achievements to eccentric lives. The rise of newspapers and magazines played a crucial role in this phenomenon, cementing the public's fascination with famous individuals.
A new study found that individuals who feel powerless are more willing to pay higher prices for status-symbol items. Researchers Derek D. Rucker and Adam D. Galinsky discovered this phenomenon through three experiments, showing that powerlessness leads to increased willingness to pay for luxury goods.
Researchers at UC Davis found that California ground squirrels and rock squirrels apply snake scent to themselves by picking up shed skin and licking their fur. This behavior helps mask the squirrel's own scent and deters snakes from attacking.
Researchers use archaeology, biochemistry, and ecology to study the behavior and ecology of northern fur seals over 1,500 years. They find evidence of reproductive behavior in prehistoric populations that differs from modern populations.
Researchers reconstructed the species' prehistoric geographical range using techniques from archaeology, biochemistry, and ecology. Prehistoric northern fur seals were year-round residents in California, nursing their young for much longer than modern fur seals.
Female Antarctic fur seals travel long distances to mate with genetically diverse males, rather than local dominant males. This behavior enables species to maintain genetic diversity, crucial for resisting disease and parasites.
Researchers found a distinctive, arboreal rodent in Peru's Manu National Park with long dense fur and a blackish crest. The discovery sheds light on the evolution of Neotropical arboreal rodents.
The Hudson's Bay Company's pursuit of profits led to ecological stress, habitat destruction, and the decline of beaver populations. The company's focus on fur trading also introduced European farming methods and crops, altering the Northwest landscape and human population dynamics.
Recent discoveries, including a photo and skin samples, have reignited hopes of finding the Miss Waldron's red colobus monkey in its remote southeastern corner of Ivory Coast. The discovery has sparked concerns about potential extinctions of other high-canopy forest-dwelling animals.
Researchers found that seal pups can recognize their mothers' calls within two to five days after birth, a crucial skill for finding each other among hundreds of fur seals. This quick recognition is essential due to the mother leaving her pup on land while she forages at sea.
The Darwin Correspondence Project has published 12 of a projected 32-volume set of Charles Darwin's letters, providing a historical view of his ideas on evolution. The project, founded in 1974, is jointly managed by the American Council of Learned Societies and Cambridge University Library.
