Effects of Supplemental dietary starch on production and reproductive characteristics in postpartum dairy cows
DownloadFall 2009
This study evaluated the effects of dietary starch on productive and reproduction parameters of postpartum dairy cows. Three diets were fed, with increasing starch levels from calving until 70 days in milk. Treatment had no effect on dry matter intake, energy balance, specific metabolic hormones...

Factors Influencing Mountain Pine Beetle (Coleoptera: Curculionidae: Scolytinae) Dispersal by Flight and Subsequent Trade-off Between Beetle Flight and Reproduction
DownloadFall 2016
The mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), has an obligatory dispersal phase before selection of a suitable host for brood production. Flight during the dispersal phase is affected by both beetle physiology and environmental factors....

Litter birth weight phenotype and maternal n-3 long-chain polyunsaturated fatty acid supplementation in pigs
DownloadSpring 2013
Research reported in this thesis investigated effects of n-3 polyunsaturated fatty acid (LCPUFA) supplementation, litter birth weight phenotype, and their possible interactions, on reproductive performance of the gilt and sow and postnatal performance of the litter. In an initial study, LCPUFA...

Local and regional demography in a migratory forest songbird and effects of forest management intensity
DownloadSpring 2014
The numerical response of forest birds to habitat alteration has been well documented in North America, but the underlying demographic processes driving these changes remain largely unknown. Among species sensitive to such alterations, the Ovenbird (Seiurus aurocapilla) shows one of the largest...

Fall 2013
The placenta is an essential transitory fetal organ responsible for the key processes of nutrient, oxygen, and waste transfer between the mother and the fetus throughout gestation. Placental size is, importantly, known to correlate to fetal weight, and the malfunction and malformation of the...

Population-level responses of fathead minnow (Pimephales promelas) to alarm substances and predator odour
DownloadSpring 2010
Alarm substances, released by injured prey, and odours from predators, such as northern pike, are chemical cues associated with increased predation risk in aquatic ecosystems. In laboratory studies, individual prey can respond to the presence of such cues by reducing conspicuous behaviours, such...

Resources and Reproductive Trade-offs Affect Fitness, Life History Traits, and Sexual Selection in Red Squirrels
DownloadSpring 2017
Animals face trade-offs throughout life between competing functions, such as between self-maintenance, reproduction, and survival. Resource allocation between these competing functions leads to different patterns of life history traits, changes in investment in reproductive effort, and different...

Rising from the ashes; an unanticipated failure with the engorgement factor voraxin leads to advances in three areas of tick biology: Developmental abnormalities and parthenogenesis, identification of a Coxiella-like symbiont and the molecular characterization of vitellogenesis in the southern African bont tick, Amblyomma hebraeum Koch (1844)
DownloadFall 2012
Weiss and Kaufman (2004, PNAS 101: 5874-5879) demonstrated that injections of fed male gonad homogenates stimulate engorgement in virgin female Amblyomma hebraeum ticks, due to the presence of the engorgement factor voraxin. They also showed voraxin's potential as part of an anti-tick vaccine:...

Seasonal phenology and reproductive behaviour of Dioryctria species Zeller (Lepidoptera: Pyralidae) in British Columbian seed orchards
DownloadSpring 2011
Seasonal phenology and mating frequency of moths in the genus Dioryctria found sympatrically in north Okanagan Valley, British Columbia seed orchards were assessed. Female moths in the abietella, auranticella, ponderosae and schuetzeella species groups were trapped in Douglas-fir, lodgepole pine...

Spring 2013
Early embryonic development is a dynamic period that requires precise and timely interaction between the developing embryo and the maternal environment. A series of studies were carried out in order to identify the vital components of this environment and to understand their temporal and spatial...
