Fall 2013
Breast cancer is the most common cancer among women in the developed world. The disease results from the combined effects of genetic, environmental, reproductive and lifestyle risk factors. Germline DNA variations identified thus far by linkage and genome-wide association studies (GWASs) account...

Heritability of tolerance to the Cry1Ab toxin of Bacillus thuringiensis in Chilo suppressalis (Lepidoptera: Crambidae)
Download2000
Cohen, M. B., Gould, F., Alinia, F.
Abstract: Heritability of Chilo suppressalis (Walker) tolerance to the Cry1Ab toxin of Bacillus thuringiensis Berliner was estimated using a half-sibling design. Artificial diet with and without Cry1Ab was infested with progenies of 20 males, each mated with 2 females, and mortality was scored 5...

How the mountain pine beetle (Dendroctonus ponderosae) breached the Canadian Rocky Mountains
Download2014-01-01
Sperling, Felix A. H., Murray, Brent W., Li, Yisu, Coltman, David W., Bohlmann, Joerg, Janes, Jasmine K., Cooke, Janice E. K., Boone, Celia K., Huber, Dezene P.W., Keeling, Christopher I., Yuen, Macaire M. S.
The mountain pine beetle (MPB; Dendroctonus ponderosae Hopkins), a major pine forest pest native to western North America, has extended its range north and eastward during an ongoing outbreak. Determining how the MPB has expanded its range to breach putative barriers, whether physical...

Improving precision of breeding values by removing spatially autocorrelated variation in forestry field experiments
Download2002
Hamann, A., Namkoong, G., Koshy, M.P.
Adjustment for micro-environmental heterogeneity in inadequately blocked field experiments is desirable to improve estimates of genetic parameters and to maximize genetic gains from selection. In three forestry field trials of red alder (Alnus rubra Bong.) we removed spatially autocorrelated...

International genetic evaluations for feed intake in dairy cattle through the collation of data from multiple sources
Download2014
Coffey, M. P., Løvendahl, P., Wang, Z., de Haas, Y., Krattenmacher, N., Berry, D. P., Crowley, J. J., Pryce, J. E., Veerkamp, R. F., Weigel, K., Macdonald, K., Spurlock, D.
Feed represents a large proportion of the variable costs in dairy production systems. The omission of feed intake measures explicitly from national dairy cow breeding objectives is predominantly due to a lack of information from which to make selection decisions. However, individual cow feed...

Investigating the genetic basis of boldness and reproductive performance traits in the grey seal (Halichoerus grypus)
DownloadSpring 2022
Individual variation provides the material for natural selection to act upon, influencing ecological and evolutionary processes. Much phenotypic variation in traits, such as behaviour and life-history, have a moderate to high heritable component, suggesting that these traits may have adaptive...

Mitochondrial DNA variation and identification of bark weevils in the Pissodes strobi species group in western Canada (Coleoptera: Curculionidae)
Download1995
Sperling, F. A. H., Langor, D. W.
Abstract: Morphological, allozyme, and chromosomal characters and ecological traits have limited value for discriminating among four closely related Pissodes spp. known from western Canada. We amplified a 1585-bp segment of mitochondrial DNA (mtDNA), including half of the cytochrome oxidase I...

New insights about barnacle reproduction: Spermcast mating, aerial copulation and population genetic consequences
DownloadSpring 2014
Barnacles are mostly hermaphroditic and they are believed to mate via copulation or, in a few species, by self-fertilization. However, isolated individuals of two species that are thought not to self-fertilize, Pollicipes polymerus and Balanus glandula, nonetheless carried fertilized...

Ontogenetic patterns in heritable variation for body size: using random regression models in a wild ungulate population
Download2005
Wilson, A.J., Coltman, D.W., Kruuk, L.E.B.
Body size is an important determinant of fitness in many organisms. While size will typically change over the lifetime of an individual, heritable components of phenotypic variance may also show ontogenetic variation. We estimated genetic (additive and maternal) and environmental covariance...
