Fall 2011
Estimating annual wolf kill rates and composition is important for assessing the impact of wolves on their prey and managing wolf-ungulate dynamics. Most studies have focused on kill rates of wolves in winter or single-ungulate dominated systems. I used high intensity GPS tracking combined with...

Solving the LP Relaxation of Distance-Constrained Vehicle Routing Problem Using Column Generation
DownloadFall 2020
The distance-constrained vehicle routing problem (DVRP) is one of the less studied variants of vehicle routing problems. Here, the objective is to deliver packages from a depot to clients with as few delivery vehicles as possible within a given time frame. In this thesis, we tackle larger...

Spatial Predation Risk and Interactions Within a Predator Community on the Rocky Mountains East Slopes, Alberta
DownloadSpring 2019
Understanding how large carnivores spatially partition the landscape is essential for understanding how they collectively pose risk to their prey. Most research on predation risk focuses on how prey respond to a single predator species, but prey respond to a community of predators. Additionally,...

Nichol, Chad, Krebs-Elaschuk, Aiden
The hairy woodpecker, Picoides villosus, is a small bird native to North America and common in the Camrose region. Consuming small arthropods and nesting in the self-excavated cavities of dead trees, the woodpecker has many ecological relationships. The hairy woodpecker competes with other...

Unusual predation attempts of polar bears on ringed seals in the southern beaufort sea: Possible significance of changing spring ice conditions
Download2008
Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.
In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...

Using drilled-undrilled shell damage analysis to estimate crushing predation frequencies in modern marine gastropod assemblages
DownloadSpring 2010
Predation is a frequently studied subject, but estimating crushing predation in mollusk communities is challenging. Shells record successful attacks, but it is not always possible to identify attacks on an individual basis. Repair scar frequency is a common proxy for crushing mortality, but shell...

Fall 2017
The degree to which predator and prey distributions overlap in space influences the probability of encounters between predator and prey, kills of prey, and consequently, how each species’ abundance varies in time and in space. Predator and prey attempt to increase or decrease overlap respectively...
