The Role of Climate Variability in Duck Population Ecology
(2019-10-23)
Climate change is having profound impacts on animal populations globally, and is expected to become a stronger stressor in future, influencing abundance and persistence of many species. In northern hemisphere bird ...
Relationships between water quality, species composition, biodiversity and ecosystem function in lakes and flooded pits exposed to uranium mining activities in Northern Saskatechewan
(2009)
Uranium mining activities have the potential to impact aquatic systems through mine drainage (runoff) and the release of treated effluent into nearby watersheds. Such anthropogenic exposure can lead to elevated concentrations ...
Some chemical and biological aspects of water pollution in a portion of the upper Qu'Appelle River system
(1967)
Water pollution has received increasing attention in recent
years. With modern industrialization and increasing urbanization, the
need for the preservation of our aquatic resources has become obvious.
Shortages of water ...
Parasite-host interactions in an arctic goose colony
(2006-12)
The arctic is currently experiencing some of the greatest rates of warming. Newly emerging diseases in the arctic are of particular interest due to the implications these may have at southern latitudes if temperatures ...
Colony site selection in bank swallows
(1984)
Bank Swallow colony site selection was studied on a 6,129 hectare area in the Qu'Appelle Valley near Fort Qu'Appelle, Saskatchewan. Comparison of 60 banks used by Bank Swallows with the 349 unused sites showed that taller, ...
Hormetic dietary phytochemicals from Western Canadian plants: Identification, characterization and mechanistic insights
(2015-02-26)
Activation of mammalian stress responsive pathways by plant secondary metabolites may contribute to the protection against certain chronic diseases afforded by fruit and vegetable consumption. This work focuses on the ...
Migratory connectivity and differential patterns of decline in Barn Swallow (Hirundo rustica) in North America: Potential effects of factors on breeding and wintering grounds
(2013-01-17)
Populations of several Neotropical migratory bird species have experienced declines in the recent decades but long-distance migrant aerial insectivores seem to be declining at greater rates than any other group. The Barn ...
Brood ecology and population dynamics of King Eiders
(2004-05-30)
Birth and death processes and the extent of dispersal directly affect population dynamics. Knowledge of ecological factors that influence these processes provides insight into natural selection and understanding about ...
Molecular and pathological differentiation of colletotrichum truncatum from scentless chamomile and legume crops
(2007-03-15)
The fungus Colletotrichum truncatum is a potential biocontrol agent (BA) against the noxious weed scentless chamomile (Metricaria perforata Mérat; syn.: Tripleurospermum perforatum (Mérat) Lainz) in western Canada. This ...
DISCRIMINATING OVERWINTERING ORIGIN AND MIGRATORY CONNECTIVITY IN A LONG-DISTANCE MIGRATORY SHOREBIRD STAGING IN THE CANADIAN PRAIRIES
(2022-09-14)
Migratory birds are experiencing widespread global declines. Shorebirds appear to be experiencing some of the most dramatic declining population trends, with the long-distance, Arctic-breeding migrants apparently losing ...
