Carbon-flux and Microbial Community Dynamics in Low-Arctic Tundra

Suzanne Simard, Susan Grayston & William Mohn
Arctic ecosystems store large amounts of carbon in organic matter that may contribute to carbon dioxide (CO2) production as climate warms, further enhancing the greenhouse effect. We know that many biological factors, including plant interactions with mycorrhizal fungi and other soil microbes, regulate plant survival and the carbon-balance of arctic tundra, but these interactions are poorly understood. Recently, new advances in technology have allowed us to study belowground communities with resolution not previously possible, leading...

Vegetation Succession on Drained Lakes in Old Crow Flats, 2007-2009

Lance Nagwan, Trevor Lantz & Erika Tizya
Temperature increases in northern ecosystems are altering the freqeuncy of natural disturbance. Increased disturbance is likely to exert a strong influence on terrestrial vegetation. In the Old Crow Flats in the Northern Yukon, we investigated the effect of catastrophic lake drainage on plant community composition, vegetation structure and microenvironment by contrasting drained lake basins of various ages with several undisturbed terrain types. The vegetation that develops on drained lakes basins is typically dominated by canopy...

Pilot scale constructed wetlands for Arctic communities

Vicente Santiago, Brent Wootton, Stephanie Collins, Sven Erik Jørgensen, Chris Metcalfe & Colin Yates
As Arctic communities evolve and populations become more concentrated and urbanized, there is a growing need to develop environmentally sustainable technologies and resource management practices. Wastewater and water treatment methods are a particular challenge for northern communities. Disparities in access to safe water treatment methods have been shown between southern/urban populations and northern/Inuit/remote communities. Current wastewater treatment systems are rudimentary in the north because of constraints caused by remoteness, climate, and socio-economic factors. Constructed wetland...
