A microsatellite polymorphism in the gamma interferon gene is associated with resistance to gastrointestinal nematodes in a naturally-parasitized population of Soay sheep

Pemberton, J. M., Coltman, D. W., Pilkington, J. G., Wilson, K., Stear, M. J.
Abstract: Free-living Soay sheep (Ovis aries) on the island of Hirta, St Kilda, Scotland, are naturally parasitized bq gastrointestinal nematodes, predominantly Teladorsagia circumcincta. In this paper we show that reduced faecal egg counts (FEC) are associated with an allele at a microsatellite...

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...

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...

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...

Krkosek, Martin, Orr, Craig, Peacock, Stephanie J., Proboszcz, Stan, Lewis, Mark A.
The resilience of coastal social-ecological systems may depend on adaptive responses to aquaculture disease outbreaks that can threaten wild and farm fish. A nine-year study of parasitic sea lice (Lepeophtheirus salmonis) and pink salmon (Oncorhynchus gorbuscha) from Pacific Canada indicates that...

The resilience of coastal social–ecological systems may depend on adaptive responses to aquaculture disease outbreaks that can threaten wild and farm fish. A nine-year study of parasitic sea lice (Lepeophtheirus salmonis) and pink salmon (Oncorhynchus gorbuscha) from Pacific Canada indicates that...
