  • Wildfires Continue to Beleaguer Western Canada

    Like tourist season, wildfire season is also in full swing in British Columbia.  Whereas tourists are welcomed to the Canadian province, wildfires are not.  In British Columbia alone there are close to 500 wildfires active to date.  Most of these wildfires are located in three general areas--in the Caribou Fire Centre located in the Frasier Plateau directly north of Vancouver, in the Kamloops Fire Centre in the Thomas Plateau, which is east of Whistler, and the Southeast Fire Centre which is east of Kamloops.  All current fires of note can be viewed on this interactive map:  http://governmentofbc.maps.arcgis.com/apps/webappviewer/index.html?id=a1e7b1ecb1514974a9ca00bdbfffa3b1 

    Wildfires in British Columbia are common at this time of year due to rising temperatures, however, this year is the third worst year in the region for forest fires.  To date 840 fires have broken out since April 1 of this year.  Although it started slow, 2017 is shaping up to be a record breaking fire season if not for numbers of fires, then for the sheer amount of hectares burned.  In an area where rainfall is the norm, to have days and weeks without rainfall is unusual and helps to create a hot, dry environment with plenty of underbrush that fires use as fuel.

  • New NOAA Fisheries Research Reveals Ecosystem Cascades Affecting Salmon

    Interpreting relationships between species and their environments is crucial to inform ecosystem-based management (EBM), a priority for NOAA Fisheries. EBM recognizes the diverse interactions within an ecosystem — including human impacts — so NOAA Fisheries can consider resource tradeoffs that help protect and sustain productive ecosystems and the services they provide.

  • Adorable alpine animal acclimates behavior to a changing climate

    As climate change brings new pressures to bear on wildlife, species must “move, adapt, acclimate, or die.” Erik Beever and colleagues review the literature on acclimation through behavioral flexibility, identifying patterns in examples from invertebrates, amphibians, reptiles, birds, mammals, and fishes, in the cover article for the August issue of the Ecological Society of America’s (ESA) journal Frontiers in Ecology and the Environment. The authors focus on the American pika (Ochotona princeps) as a case study in behavioral adaptation.

    The fourth-year undergrad led a group of U of T Scarborough students to track fallen migratory birds colliding into campus buildings over a 21-day period last fall.
