    Controls on Seasonal Nitrogen Cycling in Canadian Low Arctic Tundra Ecosystems 

    Buckeridge, Kathleen (2009-09-27)
    Soil nitrogen availability to plants is a fundamental control on the structure and functioning of arctic tundra ecosystems. Despite recent evidence that biogeochemical and microbial dynamics during the non-growing season ...

    Large-Scale Exogenous Forcing of Long-Term Pacific Salmon Production and Ecosystem Interactions in Western North America 

    Selbie, Daniel (2008-09-27)
    Pacific salmon (Oncorhynchus spp.) production strongly influences the ecosystems, cultures and economies of the Northeast Pacific. Historical variability in population sizes is complex, reflecting natural and human drivers. ...

    Examination of Metal Contamination within the UNESCO Designated Rideau River Waterway 

    LeBlond, Shannon (2009-09-27)
    The Rideau River Waterway, also known as the Rideau Canal, is a constructed navigation channel that links Ottawa to Kingston, Ontario. Opened in 1832, it was designated a Canadian Heritage Site in 2003 and a UNESCO World ...

    Cellular signalling pathways involved in thermoprotection of neural ciruit function in the locust. 

    Armstrong, Gary (2009-08-27)
    Environmental temperature is arguably one of the most important abiotic physical factors affecting insect behaviour. Temperature affects virtually all physiological processes including those that regulate nervous system ...

    Integrating theory and experimentation in the study of malaria 

    Mideo, Nicole (2009-08-25)
    Malaria poses a serious threat to much of the developing world and an enormous effort is under way to design vaccines and other novel interventions. Nevertheless, we understand very little about the ecology and evolution ...

    Sperm Production and Variance in Sperm Quality 

    Knudsen, Jill (2009-09-26)
    An unusually high level of inter- and intraspecific variability in spermatozoa has been well documented. However, recent evidence indicates that the level of variation within spermatozoa differs markedly across taxa. In ...

    Role of bubbling from aquatic sediments in mercury transfer to a benthic invertebrate in the St. Lawrence River, Cornwall, Ontario 

    Razavi, Neguysa Roxanna (2009-01-05)
    Benthic uptake of mercury (Hg) governs bioavailability to fish yet there are still large gaps in our knowledge of what mediates this process. Without this information it is difficult to ascertain where Hg accumulation in ...

    Assessing changes in pollen assemblage and charcoal accumulation during known changes in climate from c. 5,400 to 3,300 Years Before Present at the forest-prairie ecotone in Alberta, Canada 

    Lorenz, P. Christopher J. (2009-02-02)
    The ecotone between aspen parkland and mixed-grass prairie in mid-eastern Alberta is a climatically-sensitive area that has been subject to periods of enhanced aridity occurring at multi-decadal to centennial-scale cycles ...

    The Effects of Thermal Habitat and Macroinvertebrate Predation on the Crustacean Zooplankton Community of a Small Boreal Shield Lake 

    MacPhee, Shannon (2009-03-31)
    Climate change will affect all freshwater ecosystems via both direct physiological and indirect, biologically-mediated effects. Small lakes (< 10 ha) numerically dominate the Boreal Shield and represent an important habitat ...

    Why is a robin’s egg blue? Exploring the evolution of egg colour in birds 

    English, Philina (2009-05-28)
    A recent hypothesis for explaining blue-green eggs in birds suggests that they may be a sexually selected signal of female (and thus nestling) quality that males use to make parental investment decisions. Although this ...
