Spring 2014
Inconsistent results have been reported in studies investigating the relationship between serum vitamin D levels and respiratory outcomes. In this thesis, data from the Canadian Health Measures Survey were used to examine the relationship between serum 25-hydroxy vitamin D [25(OH)D] levels and...

Breebaart, L., St. Louis, V.L.
We quantified supplemental sources of calcium in the diet of nestling Tree Swallows (Tachycineta bicolor) near acid sensitive lakes in northwestern Ontario. Among the calcium-rich items brought to nest boxes by adult swallows and ingested by nestlings, fish bones (particularly flat pieces) were...

Conservation and ecology of bryophytes in partially harvested boreal mixed-wood forests of west-central Canada
DownloadFall 2010
This thesis examined the efficacy of residual forest structure for the preservation and recovery of bryophytes five to six years after partial canopy harvest in boreal mixed-wood forests of northwestern Alberta, Canada. Bryophytes were sampled in two forest types that differed in pre-harvest...

Dall sheep (Ovis dalli dalli), grizzly bear (Ursus arctos) and wolf (Canis lupus) interactions in the Northern Richardson Mountains, Canada
DownloadFall 2012
Lambert Koizumi, Catherine M S
Assessing the impact of predators on a prey population is inherently challenging, a fortiori in remote ecosystems. With this thesis, I studied the interactions between a recently declining Dall sheep (Ovis dalli dalli) population and two predators: grizzly bears (Ursus arctos) and wolves (Canis...

Density-dependent variation in lifetime breeding success and natural and sexual selection in Soay rams
Download1999
Smith, J.A., Bancroft, D.R., Clutton-Brock, T.H., MacColl, A.D., Pilkington, J., Coltman, D.W., Pemberton, J.M.
Variation in male lifetime breeding success (LBS) is central to understanding selection, yet it has rarely been measured in natural populations of large mammals. Here, we first describe variation in the opportunity for selection in cohorts of Soay rams (Ovis aries) on the archipelago of St....

This thesis consists of 2 closely linked projects that evaluate the importance of depressive symptoms (hereafter, for brevity, referred to as “depression”) for short-term prognosis after general medical hospitalizations. Project 1 systematically reviews the literature to examine whether...

Disturbance has lasting effects on functional traits and diversity of grassland plant communities
Download2022-01-01
Ellen A Smith, Emily M Holden, Charlotte Brown, James F Cahill Jr
Background Localized disturbances within grasslands alter biological properties and may shift species composition. For example, rare species in established communities may become dominant in successional communities if they exhibit traits well-suited to disturbance conditions. Although the idea...

Early emergence of structural constraints on code-mixing: evidence from French-English bilingual children
Download2000
Genesee, F., Nicoladis, E., Paradis, J.
Does young bilingual children's code-mixing obey the same structural constraints as bilingual adults' code-mixing? The present study addresses this question using code-mixing data from 15 French±English bilingual children ®lmed in conversation with both parents at six-month intervals from the age...

Effects of forest harvesting and fire on fish assemblages in Boreal Plains lakes: A reference condition approach
Download2003
Scrimgeour, G.J., Lange, M., Prepas, E.E., Westcott, K., Aku, P.K.M., Paszkowski, C.A., Tonn, W.M.
To assess the impacts of forest harvesting and fires on lentic fish assemblages in the Boreal Plains ecoregion (Alberta, Canada), we applied a reference condition approach to 37 lakes in burned, logged, or undisturbed catchments. Fish assemblages in the reference lakes were classified into two...

Environmental factors affecting an experimental low-density mass grave near Edmonton, Alberta, Canada
DownloadFall 2010
The investigation of mass graves involves aspects of high political, judicial, and emotional impact. Understanding how bodies held within mass graves change between the time they are deposited and the time they are discovered (the realm of forensic taphonomy) is vital for competent collection of...
