Inuit populations in the Canadian Arctic have asthma rates 5-11% below other Aboriginal groups, with a link found between socio-economic status and asthma. Further research is needed to understand this phenomenon.
Scientists uncover thousands of years-old hunting tools, including wooden arrows and dart shafts, as warming temperatures melt ancient ice patches in the Mackenzie Mountains. The discovery sheds new light on ancient caribou migration patterns and hunting practices.
A new study published in the International Journal of Circumpolar Health found that Inuit preschoolers in Nunavut are heavier but just as tall as their US counterparts. The study, which surveyed 26% of three to five year olds in 16 Nunavut communities, shows a remarkable change from previous work on Inuit infants.
Research on the Devon Island ice cap shows a steady decline in ice volume and area since 1985, primarily due to warmer summers. The ice cap's thinning also exposes dark soil, increasing melt rates and posing concerns for shipping and sea level rise.
A new survey technique has led to a significant increase in estimated narwhal populations, now estimated to be over 60,000. The technique uses dive data and accounting for biases to improve accuracy and provides a more accurate picture of the population's size and distribution.
Researcher Kathleen Gardiner builds broad distribution maps to track northern squid habitats, crucial for understanding the impact of climate change on Arctic marine life. The study provides valuable insights into the species' temperature tolerance and feeding grounds.
Mikhail Mikhailovich Ermolaev was a prominent Soviet Arctic scientist who worked for 13 years before being arrested and sent to the Gulag on trumped-up charges. Despite harsh conditions, he eventually resumed his academic career and established a new department at Kaliningrad State University.
A team of scientists predicts that warmer temperatures in the Arctic will create challenges for seabirds' nesting habits. The study found that increasing storm events, heavy fog, and wet snow will impact birds adapted to cold, dry summers, making them more susceptible to mortality.
A long-term study found polar bears in the southern Beaufort Sea are shifting their habitat use from sea ice to land and open water, increasing human-bear interactions. The study, conducted between 1979 and 2005, shows a significant increase in bear sightings on land and in open water.
Researchers found that organic fertilizer had a neutral or negative effect on plant growth, while mineral fertilizer showed mixed results. Dune grass performed well with the addition of fertilizer, but beach pea was negatively impacted. ATVs continue to be a major obstacle to revegetation efforts in the area.
Researchers in northern Canada analyzed tree rings for accurate past climate information, finding strong correlations between temperature data and carbon and oxygen isotopes. This new method reduces lab costs and allows for more affordable climate change research.
Researchers have found northern brown bears feeding on migrating broad whitefish in a stream in the Mackenzie Delta region. This discovery highlights the importance of considering the impact of development activities on these bears' diets and survival.
