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...

Ectomycorrhizae of Jack Pine and Green Alder: Assessment for the Need for Innoculation, Development of Innoculation Techniques, and Outplanting Trials on Oil Sands Tailings
Download1988
The overall objectives of these studies were to characterize the mycorrhizal status of jack pine and green alder which are prime candidates as reclamation species for oil sand tailings and to determine the potential benefits of mycorrhizae on plant performance. This entailed determining the...

Effects of environmental and disturbance gradients on native bee diversity, abundance and composition in Alberta’s prairies
DownloadFall 2017
Native bees provide pollination services to a range of crops, supporting food production and the global economy. They also support the fitness of native flowering plants and terrestrial plant diversity. These functions are delivered by a diverse community of bees with a broad spectrum of life...

Examining the Biology and Monitoring Tools of Sitodiplosis mosellana in the Peace River region, Alberta
DownloadSpring 2019
Wheat midge, Sitodiplosis mosellana Géhin (Diptera: Cecidomyiidae), is an invasive pest of wheat that has spread into the Peace River region of Alberta, Canada. The biology and monitoring of wheat midge has not previously been examined in this region. Wheat midge overwintering density and...

From Farm Crisis to Food Crisis: Neoliberal Reform in Canadian Agriculture and the Future of Agri-Food Policy
DownloadFall 2013
This dissertation begins by providing an overview of Canadian agriculture policy during the first half of the twentieth century. It examines the origins of railway transportation subsidies, farm income subsidies, and the Canadian Wheat Board (CWB), policy instruments that became structural...

From State to Empire: Human Dietary Change on the Central Plains of China from 770 BC to 220 AD
DownloadFall 2016
This study is designed to investigate human dietary features on the Central Plains of China during the social transition from regional states to centralized empire, which occurred during the period from the Eastern Zhou to the Han Dynasty (770BC-220 AD). Human remains from four sites and animal...

Jackson, D.A., Walker, S.C., Poos, M.S.
Functional diversity is an important concept in community ecology because it captures information on functional traits absent in measures of species diversity. One popular method of measuring functional diversity is the dendrogram-based method, FD. To calculate FD, a variety of methodological...

Spring 2014
The worldwide biodiversity crisis has intensified the need to better understand how biodiversity and human disturbance are related. Yet this relationship lacks both consensus in theoretical expectations and consistency in observed empirical patterns. I present one of the largest extent studies...
