Minimally-invasive assessments of the behavioural and physiological effects of enriched colony cages on laying hens
Download2011
Korver, Doug R., Schaefer, Allan L., Cook, Nigel J., Feddes, John J. R., Church, John S., Haley, Derek B.
The well-being of laying hens in cages of 5, 10, 20 and 40-birds/cage, and enrichment with perches, nest boxes and scratch pads, was assessed using behavioral and physiological parameters. Laying hens were Lohmann Brown (n = 360) and White Leghorns (n = 360), housed from 17 to 65 weeks of age....

Urbanization is viewed as a major threat to global biodiversity because of its role in the loss and fragmentation of low-lying, productive habitats associated with coastal plains and river valleys. My study examines the effects of urbanization on the movements and distribution of songbirds in...

Category perception, as Herrnstein (1990) defined it, is a powerful and pervasive cognitive ability possessed by every species in which it has been adequately tested. We have studied category perception of vocal communication signals in songbirds for over 20 years. Our first studies provided us...

We report myiasis by Lucilia silvarum with an overall prevalence of 0.9% in amphibian populations in boreal Alberta. In the period 1998–1999, we documented L. silvarum infestations in wild populations of wood frog (Rana sylvatica), boreal chorus frog (Pseudacris maculata), boreal toad (Bufo...

Physical Activity Information Seeking and Advertising Recall
2011
Plotnikoff, R., Bauman, A., Berry, T. R., Spence, J. C.
Abstract: The purposes of this research were to examine the characteristics of those who look for physical activity-related information, where they find it, and to examine what types of physical activity-related advertisements are recalled (i.e., publicly funded or commercial). These purposes...

Pitch perception in vocal learners: Fundamental shared components of pitch processing and biological relevance
DownloadSpring 2013
Pitch perception is important in both music and language perception in humans. Vocal learners, including humans, share the property of learning their vocalizations from a tutor when young. Similar behavioural and neural mechanisms underlying vocal production among different species of vocal...

Wildlife habituation near urban centers can disrupt natural ecological processes, destroy habitat, and threaten public safety. Consequently, management of habituated animals is typically invasive and often includes translocation of these animals to remote areas and sometimes even their...

Lankau, Hedwig Erika Gertraude
I investigated how songbirds respond to seismic lines as the vegetation cover on lines regenerates and how long seismic line effects on songbirds persist. I found that line age was poorly correlated with natural vegetation recovery and that after an initial increase in recovery after 20 years the...

In the present work, we focused our attention on triacylglycerols. Their phase behavior strongly influences production processes of products based on fats and oils. However, the mechanisms controlling such behavior are not well understood. Hence, we decided to utilize computer simulation to gain...
