Fall 2011
In the Rocky Mountain foothills of Alberta, Canada, activities of the forestry and energy sectors have resulted in the installation of tens of thousands of stream-crossing structures. In fifteen Athabasca River basins I found that culverts impeded upstream movements of non-sportfish species...

Landscape ecologists have been eager to make their research applicable to forest management. We examine how landscape ecology has contributed to shaping the way forest management is currently practiced. Landscape ecology research in forested ecosystems call be divided into two general areas: (1)...

Movement Patterns of Adult Male Ovenbirds during the Post-Fledging Period in Fragmented and Forested Boreal Landscapes
Download2001
Bayne, Erin M., Hobson, Keith A.
Movement of forest songbirds among isolated forest patches following breeding represents an important but poorly understood component of landscape ecology and metapopulation theory. Using radio-telemetry, we followed 44 male Ovenbirds (Seiurus aurocapillus) during the post-fledging period to...

Lamberson, Leslie, Pagano, Steven, Hogan, James
The rate-dependent compressive response and resulting fragmentation characteristics of dry ox cortical bone and cyanoacrylate-based cortical bone surrogate material was investigated in two material orientations. Tests were conducted under quasi-static (10−3 s−1) and dynamic (103 s−1) loading in...

Nest predation on forest songbirds in a western boreal forest landscape altered by energy sector linear features
DownloadFall 2013
Nest predation is a major source of reproductive failure for many species of songbirds. Habitat fragmentation by human land use creates edge habitat that can alter predator-prey dynamics, create ecological traps, and reduce the amount of high quality habitat available for sustaining bird...

Conversion of cycloalk-2-enones into 2-methylcycloalkane-1,3-diones - Assessment of various Tamao-Fleming procedures and mechanistic insight into the use of the Me3SiMe2Si unit.

Yu, Goujun, Clive, Derrick L. J.
Conjugate addition of Me3SiMe2SiLi to cycloalk-2-en-1-ones, ketalization, Tamao-Fleming oxidation (Bu4NF, then H2O2, KHCO3), TPAP oxidation and acid hydrolysis generates 2-methyl cycloalkane-1,3-diones. Ketalization is needed in order to prevent addition of Me3Si- to the carbonyl. The...

In-situ visualisation of dynamic fracture and fragmentation of an L-type ordinary chondrite by combined synchrotron X-ray radiography and microtomography
Download2021-05-01
Farbaniec, Lukasz, Chapman, David J., Patten, Jack R.W., Smith, Liam C., Hogan, James D., Rack, Alexander, Eakins, Daniel
The relationship between the dynamic mechanical properties of stony meteorites and their microstructures was investigated in-situ for an L-type ordinary chondrite using a split-Hopkinson pressure bar apparatus and ultra-high speed phase-contrast X-ray radiography at the European Synchrotron...

The Health of Animals Act and Regulations: an example of how Canada has failed to protect farmed animals
DownloadFall 2014
Abstract Farmed animal welfare is an increasingly pressing issue both in Canada and abroad. This thesis surveys the current laws Canada has in place to protect farmed animal welfare. It looks at the Health of Animals Act and regulations as an example of why laws that should protect farmed animals...

Effects of climate and forest structure on duration of forest tent caterpillar outbreaks across central Ontario, Canada
Download1998
Cooke, B., Roland, J., Mackey, B. G.
Abstract: We examined the effect of forest structure and climate enlarge-scale and long-term patterns of outbreaks of forest tent caterpillar, Malacosoma disstria Hbn., across central Ontario. This was done using previously published data on outbreak duration and forest heterogeneity, combined...
