A re-examination of ZENK expression following hetero- and conspecific playback in the zebra finch auditory forebrain
DownloadFall 2016
Zebra finches (Taeniopygia guttata) are one of the most sexually dimorphic songbirds used as model species, not only in appearance but also in vocal production; while males produce both calls and songs, the females only produce calls. This dimorphism in the zebra finch provides a means to...

An investigation of sex differences in acoustic features of the chick-a-dee call of black-capped chickadees (Poecile atricapillus)
DownloadFall 2015
The chick-a-dee call of the black-capped chickadee (Poecile atricapillus) is composed of four main note types (A, B, C, and D) that occur in a fixed order. Sex differences have been identified in a number of black-capped chickadee vocalizations (including tseet calls and fee-bee songs) and in the...

Black-capped chickadees (Poecile atricapillus) are a species of North American songbirds commonly studied for their unique vocalizations. The two most studied vocalizations are their fee-bee song, used for mating and territory defense, and their name-sake chick-a-dee call, which has multiple...

Understory protection is a harvesting approach that seeks to protect understory conifers during hardwood harvesting in mixedwood forests. While understory protection harvesting has been implemented for over a decade in Alberta, there has been no study of its ecological value to birds. We surveyed...

Chickadee behavioural response to varying threat levels of heterospecific and conspecific calls
DownloadFall 2015
Chickadees produce many vocalizations, including the chick-a-dee call that they use as a mobbing call in the presence of predators. Previous research has shown that chickadees produce more D notes in their mobbing calls in response to high-threat predators compared to low-threat predators, and...

Canada’s boreal forest is the breeding ground for some 288 species of resident and migratory birds. Approximately 65% of the species that are currently of highest conservation priority in the boreal region are associated with wetlands and riparian areas. Although estimates vary with scale and...

The Canadian boreal forest is vital breeding habitat for North American songbirds. Extensive anthropogenic disturbances within this biome are therefore of conservation concern. Using unharvested stands as controls, I examined the effects of variable retention management (VRM) relative to...

Dealing with a latent danger: parents communicating with their school-age preadolescent children about smoking - a grounded theory study
DownloadSpring 2011
Smoking in youth continues to be an important public health issue. Because adolescence is the key period for smoking initiation, prevention efforts need to take place before the adolescent years. Little is known about parental smoking prevention interventions. The purpose of this study,...

We investigated the problem of constructing a near-field link budget to wirelessly communicate with high data rate (e.g. 3.125 Mbps) implantable circuitry located few centimeters under the skin using spread spectrum technique. Different methods and frequency bands were analyzed to choose the...
