A study led by researchers at the University of Ottawa and published today inProceedings of the Royal Society Bhas found that a lake ecosystem was severely affected by arsenic contamination from the Giant Mine, which produced over seven million ounces of gold while it was active, between 1948 and 2004. Over 20,000 tonnes of toxic arsenic trioxide were released from the Giant Mine’s roaster stack over the years as part of its process to extract gold from arsenopyrite ore. Read the complete article.
Collaborative research by scientists at the University of Ottawa and the Government of Alberta’s Environment and Parks ministry has found that the concentrations of polycyclic aromatic hydrocarbons (PAHs) have increased in lake sediments near in-situ drilling wells since production began at the Cold Lake oil sands development in the 1980s. PAHs, a diverse group of organic contaminants, have been linked to cancer and other adverse health effects in humans. Read the complete article.
Arbuscular mycorrhizal fungi (AMF) enhance plant’s ability to extract nutrients from the soil and are widely used as bio-fertilizers to improve plant yield in organic agriculture. The genetic system of these organisms has long been obscure, hampering our ability to produce new strains that are more optimal for our green economy. A study led by the laboratory of Nicolas Corradi has finally unlocked their genetic secrets, opening new avenues for AMF strain improvement and their environmental application. The work is published in Nature Microbiology.” Read the complet article.
Faculty of Science professor François Chapleau set out to shake the world of some University of Ottawa students, in the gentlest way, by providing a scholarship that could help ease the financial pressures of a university education. Read the complete article.
Climate change is heating things up, and new research shows that some of North America’s most cherished species can’t take the heat.
When average temperatures in a given area rise, some species move to cooler locations. This is because all species can only exist within a certain range of temperatures. If a species cannot move to more suitable areas quickly enough, or if weather patterns become erratic, the species may face a real risk of local extinction in areas that are too warm. According to a recent study published in Ecology and Evolution, University of Ottawa researchers found that some North American songbirds are becoming extinct in warmer regions of the continent.

American Botanical Council’s Botanical Excellence Awards were founded in 2006. They are presented each year at the American Botanical Celebration, which takes place in conjunction with the Natural Products Expo West. Recipients are chosen based on their contributions to the herbal and botanical community during the previous year.
