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...

Price, M. A., Hudson, R. J., Wairimu, S.
Ten yearling wapiti stags were used to investigate effects of winter nutrition on subsequent growth on summer pasture. One group of five (LOW) was wintered on medium-quality hay, and the other group of five (HIGH) was wintered on hay and alfalfa–barley pellets (16% crude protein). By the time...

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...

Intake, rumen digesta pool sizes, ruminal digestion rates, passage rates of liquid and particle pools and faecal particle-size distrubutions of grass, browse and lucerne diets were compared in ruminally fistulated moose, wapiti and cattle. For each diet, ruminal digestion rates (nylon bag...

Personality has been documented in diverse taxa and growing attention is being directed towards the ecological implications of consistent variation in individual behaviour. These implications include the rise in habituation behaviour by wildlife living in human-disturbed areas, which has resulted...

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...

Foraging-predator avoidance trade-offs made by migrant and resident elk (Cervus elaphus) on their sympatric winter range
DownloadFall 2009
Migratory behaviour of the Ya Ha Tinda (YHT) elk population is diminishing while the number of residents remaining on the YHT winter range year-round is increasing. Previous research addressing the fitness consequences of each migratory strategy assumed there was no advantage to either segment...
