A comparison of passive monitoring methods for gray wolves (Canis lupus) in Alberta, Canada
DownloadSpring 2019
Remote camera traps are often applied to large mammal conservation and management programs because they are cost-effective, allow for repeat surveys, and can be deployed for long time periods. Additionally, statistical advancements in calculating population metrics, such as density, from camera...

We construct a continuum model for biological aggregations in which individuals experience long-range social attraction and short range dispersal. For the case of one spatial dimension, we study the steady states analytically and numerically. There exist strongly nonlinear states with compact...

A discrete flow (S,X) is a semigroup S acting on a set X where both S, and X are equipped with the discrete topology. Amenability of semigroups is a topic that explores the existence of measures that are invariant under the semigroup multiplication. The goal of this thesis is to generalize these...

2015 marks the 50th anniversary of Moore's law, which has described the exponential progress in semiconductor patterning technologies, enabling creation of smaller circuitry features at greater densities. These continued hardware developments, economically mass manufactured, have made possible...

Are the “ seeds ” of spatial variation in cyclic dynamics apparent in spatially-replicated short time-series ? An example from the forest tent caterpillar
Download2005
Variation in the pattern of dynamics of the forest tent caterpillar was assessed over a 13-year interval of population collapse and increase among 68 sites within a 420 km2 region. Patterns of population change were compared with the level of forest fragmentation among sites, and interpreted in...

Beyond Viscosity—How Density, Vibration and Interfacial Tension Affect Solvent Aided Bitumen Production
DownloadFall 2016
Bitumen and heavy oil comprise a significant percentage of proven oil reserves globally. The environmental impacts of producing these resources with current technologies is a concern for environmentalists, oil producing companies, resource rich jurisdictions and society at large. Dilution of the...

Biology of Caloptilia fraxinella (Lepidoptera: Gracillariidae) on ornamental green ash, Fraxinus pennsylvanica (Oleaceae)
Download2009
Abstract: The ash leaf cone roller, Caloltilia firaxinella (Ely), is a leaf-mining moth that has recently become a significant pest of horticultural ash, Fraxinus L., species in communities throughout the western prairie provinces of Canada. The study examines the spatial and temporal within-host...

Bhagavathula, Kapil Bharadwaj, Meredith, Christopher S., Ouellet, Simon, Romanyk, Dan L., Hogan, James D.
This study presents a comprehensive experimental study of the evolution of Poisson’s ratio and tangent modulus of polymeric foams during rate dependant uniaxial compression. In this study, polyurethane foams with densities of 195 kg/m3, 244 kg/m3, and 405 kg/m3 obtained from PORON (XRD series)...

Wilson, A.J., Pemberton, J.M., Coltman, D.W., Kruuk, L.E.B., Pilkington, J.G., Mifsud, D.V., Clutton-Brock, T.H.
There has recently been great interest in applying theoretical quantitative genetic models to empirical studies of evolution in wild populations. However, while classical models assume environmental constancy, most natural populations exist in variable environments. Here, we applied a novel...
