A longitudinal and cross-sectional examination of the relationship between reasons for choosing a neighbourhood, physical activity and body mass index
Download2010
Berry, T. R., Blanchard, C., Selfridge, G., Spence, J. C., Edwards, J., Cutumisu, N.
Abstract: Background: The purpose of this study was to examine the relationship between body mass index and neighborhood walkability, socioeconomic status (SES), reasons for choosing neighborhoods, physical activity, fruit and vegetable intake, and demographic variables. Methods: Two studies,...

A review of metrics of distribution with application to Conservation Units under Canada's Wild Salmon Policy
Download2011-01-13
Carrie A. Holt, Stephanie J. Peacock
Metrics describing the distribution of individuals among groups and across the landscape can provide information on the resilience of a population that may not be apparent from abundance information alone. The distribution of spawners has therefore been recommended as an indicator of the...

Acid-base properties of cyanobacterial surfaces I: Influences of growth phase and nitrogen metabolism on cell surface reactivity
Download2008
Konhauser, K.O., Owttrim, G.W., Smith, D.S., Lalonde, S.V.
Significant efforts have been made to elucidate the chemical properties of bacterial surfaces for the purposes of refining surface complexation models that can account for their metal sorptive behavior under diverse conditions. However, the influence of culturing conditions on surface chemical...

Krkošek, M., Ashander, J., Lewis, Mark A., Frazer, N.
The exchange of native pathogens between wild and domesticated animals can lead to novel disease threats to wildlife. However, the dynamics of wild host-parasite systems exposed to a reservoir of domesticated hosts are not well understood. A simple mathematical model reveals that the spill-back...

Antimicrobial Use Surveillance Indicators: Use and Practicality in Salmonid Aquaculture Settings
DownloadFall 2021
Antimicrobial resistance (AMR) is a unique threat to One Health, and salmonid aquaculture industries are increasingly challenged to demonstrate responsible antimicrobial stewardship. Indicators and metrics to quantify antimicrobial use (AMU) data can comparatively enhance understanding of...

Aquaculture-induced changes to dynamics of a migratory host and specialist parasite: a case study of pink salmon and sea lice
Download2012-01-01
Ashander, Jaime, Lewis, Mark A., Krkošek, Martin
Exchange of diseases between domesticated and wild animals is a rising concern for conservation. In the ocean, many species display life histories that separate juveniles from adults. For pink salmon (Oncorhynchus gorbuscha) and parasitic sea lice (Lepeophtheirus salmonis), infection of juvenile...

Broccoli sprout supplementation during placental insufficiency confers structural and functional neuroprotection to the fetal rat
DownloadSpring 2010
Background: Perinatal ischemic brain injury leads to developmental disability (DD), which accounts for 30% of disabilities in children. Antepartum risk, or risk occurring prior to birth occurs in more than 90% of cases. This study investigated whether maternal ingestion of a natural health...

Peacock, Stephanie J., Connors, Brendan M., Krkošek, Martin, Irvine, James R., Lewis, Mark A.
The impact of parasites on hosts is invariably negative when considered in isolation, but may be complex and unexpected in nature. For example, if parasites make hosts less desirable to predators then gains from reduced predation may offset direct costs of being parasitized. We explore these...

Longrich, N. R., Currie, P. J., Erickson, G. M., Horner, J. R.
Background: Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion. However, there is little direct evidence of diet or feeding habits in this species. Methodology/Principal Findings: Examination...
