Animal cognition and animal personality: Individual differences in exploratory behaviour, learning, vocal output, and hormonal response in an avian model
DownloadFall 2012
The foremost goal of this thesis is to integrate the study of animal cognition with the field of animal personality. In the early 20th century, Pavlov integrated these fields by describing an interaction between associative learning and dogs that exhibited different behavioural types. Since...

Fall 2021
The field of animal personality, the study of adaptive among-individual behavioural differences in animal populations, has both exploded in popularity in the last few decades and come under heavy scrutiny by behavioural ecologists. The sudden interest in the field stems from the widespread...

A reproductive phenotype that has high variability, repeatability, heritability, and association with fertility could become an excellent candidate for genetic selection to augment fertility in dairy cows. Therefore, the general objective of this research was to evaluate the aforementioned...

Does fluctuating selection maintain variation in nest defense behavior in Arctic peregrine falcons (Falco peregrinus tundrius)?
DownloadFall 2021
Within populations, individuals often exhibit repeatable among-individual differences in behavior, and in some cases, these are linked to different fitness outcomes. Several mechanisms have been proposed to contribute to the maintenance of repeatable among-individual variation in behavior. Here...

Effect of breed type and residual feed intake on meat and collagen quality and expression of genes involved in collagen synthesis and degradation in bovine m. gluteus medius
DownloadSpring 2020
Residual feed intake (RFI) is an index of feed efficiency that has been demonstrated to be moderately heritable, with cattle having low RFI values being efficient as they consume less feed for the same weight gain. This may be of financial benefit to producers, but to be fully beneficial to...

Estimation of genetic and phenotypic parameters for ultrasound and carcass merit traits in crossbred beef cattle
Download2014
Bruce, H. L., Plastow, G. S., Moore, S. S., Wang, Z., Nkrumah, D., Miar, Y., Durunna, O.
Ultrasound measurements of 852 crossbred steers along with carcass merit measurements on 756 of them were used to examine their genetic and phenotypic parameters. Traits including ultrasound backfat thickness (UBF), ultrasound ribeye area (UREA), ultrasound marbling (UMAR), carcass weight (CWT),...

Goonewardene, L. A., Wang, Z., Yang, R. C., Huedepohl, C.
Data from the Alberta Agriculture Food and Rural Development data base, which keeps inventories of elk producers and velvet production information (n = 12 724), were used to estimate genetic and phenotypic variances, heritability and repeatability estimates for velvet antler using REML methods....

Dhir, N., Rweyongeza, D., Yeh, F.
We estimated heritabilities and correlations for bud flushing and growth traits of white spruce seedlings, and the correlations of seedling traits with 10- and 11-year height of the same families in the field. The seedling greenhouse experiment had a randomized complete block design with 30...

Genetic variation in height, branch and needle lengths of Pinus sylvestris L. from Siberia tested in Alberta, Canada
Download2003
Dhir, N.K., Rweyongeza, D., Yeh, F.C., Dancik, B.P.
We performed the analysis of variance and covariance on height, branch length, height to branch length ratio, and needle length measurements from thirty open-pollinated families of Pinus sylvestris L. from Siberia, Russia. This progeny trial was replicated on three sites in central Alberta,...
