    The evolution of species' geographical range limits: an empirical test using two coastal dune plants, Camissonia cheiranthifolia (Onagraceae) and Abronia umbellata (Nyctaginaceae) 

    Samis, Karen Elizabeth, 1974- (2007-07-05)
    Every species has a limit to its geographic distribution. The problem is that we don’t really know why. Classical explanations propose that range limits occur where the ecological conditions overwhelm adaptation and ...

    The Role of Invasive Bythotrephes longimanus in Lake Food Webs 

    Hatton, Elizabeth Courtney (2008-01-15)
    Bythotrephes longimanus, a predatory exotic cladoceran, has spread rapidly to numerous lakes through the Laurentian Great Lakes region of Ontario and North America. Post-invaded lakes are known to have reduced zooplankton ...

    Co-immunoprecipitation analysis of the phosphoenolpyruvate carboxylase interactome of developing castor oil seeds 

    Uhrig, Richard Glen (2008-01-09)
    Co-immunoprecipitation (co-IP) followed by proteomic analysis was employed to examine the phosphoenolpyruvate carboxylase (PEPC) interactome of developing castor oil seed (COS) endosperm. Earlier studies suggested that ...

    Chemical and biological recovery of Killarney Park, Ontario Lakes (1972-2005) from historical acidification 

    Shead, Justin A. (2007-10-01)
    Forty-five lakes in Killarney Provincial Park and the surrounding area in south-central Ontario, Canada, were sampled for crustacean zooplankton and water chemistry in the summer of 2005. For each of the lakes, we had ...

    Assessing Thule Inuit impacts on High Arctic lakes and ponds : a paleolimnological approach 

    Hadley, Kristopher R. (2008-01-03)
    Until recently it has been widely believed that significant anthropogenic influences on the environment began in Canada following the onset of European colonization. However, our paleolimnological data indicate that ...

    Stress responses in an outbred, wild-derived hamster, Phodopus campbelli: Individuality in the cortisol response to acute restraint stress and the absence of strong association with behavioural responses to acute restraint 

    Guimont, Francois (2009-02-11)
    Glucocorticoid reactivity is often used as a biomarker of emotional stress status in animals and man. Likewise, behavioural responses of individuals to standardized stresses are also widely used to assess the magnitude of ...

    Developmental, but not activational, roles for estradiol and its receptor in paternal and sexual behaviour of Phodopus campbelli males 

    Timonin, Mary Elizabeth (2008-09-17)
    The neuroendocrine basis of paternal behaviour is hypothesised to be homologous to that of maternal behaviour, with the expression of paternal behaviour resulting from the activation of estrogen-sensitive pathways in the ...

    Diatom Community Responses to Water Quality Improvements in Lakes Recovering From Acidification and Metal-Contamination Near Wawa, Ontario, Canada: a Paleolimnological Perspective 

    Greenaway, Christine (2009-04-30)
    In response to sulphur dioxide emission reductions in North America and Europe, there has been a recent shift in research focus towards understanding ecosystem recovery. Evidence for reversibility in the effects of ...

    Climate and environmental change inferred from diatom communities in Lake Challa (Kenya-Tanzania) 

    Milne, Isla (2007-08-09)
    Lake Challa is a 5 km2, 97m deep freshwater crater lake located at 880m elevation on the southeast slope of Mount Kilimanjaro (Kenya-Tanzania). Information gained from a preliminary limnological survey of Lake Challa, ...

    Black-Capped Chickadee Dawn Chorus Singing Behaviour: Evidence for Communication Networks 

    Foote, Jennifer (2008-09-18)
    There has been a recent paradigm shift in the study of animal communication from examining interactions as dyads to considering interactions as occurring in a communication network. The dawn chorus of songbirds, a striking ...
