A multi-scale test of the forage maturation hypothesis in a partially migratory ungulate population
Download2008
McDermid, G., Hebblewhite, M., Merrill, E.
The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake...

Assessing uncertainties related to the use of satellite remote sensing indices to estimate Gross Primary Production
DownloadSpring 2024
Methods to quantify Gross Primary Production (GPP) are classified into two categories: Eddy Covariance techniques (EC) and satellite data-driven. EC techniques can measure carbon fluxes directly, albeit with spatial constraints. Satellite data-driven methods are promising because they overcome...

Characterizing an in-situ fraction of Photosynthetic Active Radiation product for implementation in the validation of MODIS-derived fraction of Photosynthetic Active Radiation products using continuous-wavelet transforms
DownloadSpring 2020
The goal of this thesis is to address the need to improve forestry monitoring and satellite validation techniques to better contextualize the effects that human-induced climate change is having on tropical dry forests (TDFs). Climate change is expected to change regional and global precipitation...

Stable home ranges can emerge in a generic forager using a two-part memory system and rules derived from optimal foraging theory. My objective was to evaluate the underlying assumptions of this promising theoretical model using data from two populations of elk. Using a spatiotemporal scan...

Evaluation of MODIS-LAI products in the tropical dry secondary forest of Mata Seca, Minas Gerais, Brazil
DownloadSpring 2013
Leaf Area Index (LAI) advances scientific knowledge of the role of secondary forests in forest area conservation. MODIS-LAI products provide an alternative, efficient and cost-effective method for measuring LAI in Tropical Dry Forests (TDFs). The performance of MODIS-LAI satellite products in a...

Livestock trampling impacts have been assessed in many Alberta grassland ecosystems, but the impacts of animal trampling on Aspen Boreal ecosystems have not been documented. This study compared the effects of high intensity [4.16 animal unit month per ha (AUM) ha-1] short-duration grazing (SDG)...

Monitoring the effects of climate change in the Tropical Dry Forest of the Chamela-Cuixmala Biosphere Reserve
DownloadFall 2012
Tropical dry forests are among the most exploited and less conserved of large tropical ecosystems. This study shows advanced remote sensing techniques used to determine the land cover status of the Chamela-Cuixmala Biosphere Reserve (Mexico). Within the context of the primary basins in the...

Monitoring year-to-year variability in dry mixed-grass prairie yield using multi-sensor remote sensing
DownloadFall 2012
The Normalized Difference Vegetation Index (NDVI) and harvested biomass were compared to assess rangeland productivity (above-ground green biomass or “yield”) in southern Albertan dry mixed-grass prairie. Seasonal trends during the 2009 and 2010 growing seasons were investigated using harvested...

Fall 2016
Roads are a prevalent, ever-increasing form of human disturbance on the landscape. In many places in western North America, energy development has brought human and road disturbance into seasonal winter range areas for migratory elk. In this population, I studied individual habitat selection...
