Knowledge of relatedness between pairs of individuals plays an important role in many research areas including evolutionary biology, quantitative genetics, and conservation. Pairwise relatedness estimation methods based on genetic data from highly variable molecular markers are now used extensively as a substitute for pedigrees. Although the sampling(More)
There has recently been great interest in applying theoretical quantitative genetic models to empirical studies of evolution in wild populations. However, while classical models assume environmental constancy, most natural populations exist in variable environments. Here, we applied a novel analytical technique to a long-term study of birthweight in wild(More)
Spatial patterns of genetic variation in interacting species can identify shared features that are important to gene flow and can elucidate co-evolutionary relationships. We assessed concordance in spatial genetic variation between the mountain pine beetle (Dendroctonus ponderosae) and one of its fungal symbionts, Grosmanniaclavigera, in western Canada(More)
Individual differences in sexual behavior have received much attention by evolutionary biologists, but relatively little is known about the proximate causes of this variation. We studied the quantitative genetics of male and female sexual behavior of captive zebra finches and found surprisingly strong maternal effects (differing between individual mothers)(More)
Accurate stock identification is important for forest management, yet this can be a challenge for tree species that hybridize naturally. Species discriminating molecular markers provide a means to identify stock with high accuracy. In Canada, lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) and jack pine (Pinus banksiana Lamb) form a large(More)
Eukaryote genomes contain repetitive DNA sequences broadly classified as dispersed (long interspersed elements [LINEs], and short interspersed elements [SINEs]) or tandem repeats (micro-, minior maxisatellite DNAs). Dispersed and tandem repeats are thought to have arisen and been propagated in the genome by a variety of mechanisms; SINEs and LINEs by(More)
Chronic wasting disease (CWD) is a fatal disease of North American cervids that was first detected in a wild, hunter-shot deer in Saskatchewan along the border with Alberta in Canada in 2000. Spatially explicit models for assessing factors affecting disease detection are needed to guide surveillance and control programs. Spatio-temporal patterns in CWD(More)
