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.
The Liber Ero Fellowship Program supports emerging conservation leaders and gives them the training, networking, and encouragement to solve important conservation questions facing humanity. Congratulations!
Kathryn Hargan currently holds a W. Grafield Weston Postdoctoral Fellowship for northern research at the University of Ottawa. She received her Masters of Science from Trent University (2010) and completed her PhD in paleolimnology at Queen’s Univerisity (2014). Kathryn’s postdoctoral research in the Canadian Artic will help to yield an understanding of the biotic (e.g. seabirds) and abiotic (e.g. atmospheric) role in the transfer and concentration of contaminants and heavy metals to coastal sites, and how this transfer from oceans and southern latitudes may be influenced by climate change.
Mercury is a toxic element with no known biological function. Daniel Gregoire and Alexandre Poulain, from the Biology department, demonstrate that mercury can be beneficial to microbial growth by acting as an electron acceptor during photosynthesis. Their work was summarized and published in Nature Geoscience.
Professor Tom Moon has carried out pioneering studies on fish liver metabolism, leading to groundbreaking investigations into the effects of environmental toxins on hepatic function and metabolism. He has also been a leader in establishing the field of “endocrine disruption”, the stress on fish related to environmental contaminants. Professor Moon has been an effective mentor of all levels of trainee; no fewer than nine of whom have attained University academic positions.
Each year the Division of Comparative Physiology and Biochemistry recognizes a young investigator for distinguished contributions to comparative physiology and biochemistry or to related fields of functional and integrative biology. The award offers the awardee a fantastic opportunity to communicate this research via a large lecture at this year’s SICB conference.
