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...

Trade-offs between dispersal and reproduction are known to be important drivers of population dynamics, but their direct influence on the spreading speed of a population is not well understood. Using integrodifference equations, we develop a model that incorporates a dispersal–reproduction...

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...

Responses to n-3 fatty acid (LCPUFA) supplementation of gestating gilts, and lactating and weaned sows
Download2012
Smit, M. N., Patterson, Jennifer L., Spencer, Joel D., Dixon, Walter T., Dyck, Michael K., Foxcroft, George R., Cameron, Ashley C., Webel, Stephen K.
Feeding n-3 long-chain polyunsaturated fatty acids (LCPUFA) to gilts or sows has shown different responses to litter growth, pre-weaning mortality and subsequent reproductive performance of the sow. Two hypotheses were tested: (1) that feeding a marine oil-based supplement rich in protected n-3...

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:...
