    Abstract Background: Chronic stress is considered to be one of many causes of human preterm birth (PTB), but no direct evidence has yet been provided. Here we show in rats that stress across generations has downstream ...

    Background: Campylobacter jejuni causes enterocolitis in humans, but does not incite disease in asymptomatic carrier animals. To survive in the intestine, C. jejuni must successfully compete with the microbiota and overcome ...

(Public Library of ScienceArts and ScienceDepartment of Biological SciencesLethbridge Research CentreUniversity of LethbridgeAgriculture and ForestryPublic Health Agency of Canada, 2016)
    Cattle are the primary reservoir of the foodborne pathogen Escherichia coli O157:H7, with the concentration and frequency of E. coli O157:H7 shedding varying substantially among individual hosts. The term ‘‘super-shedder” ...

(Public Library of ScienceArts and ScienceDepartment of Biological SciencesPublic Health Agency of CanadaOntario Agency for Health Protection and PromotionUniversity of Lethbridge, 2012)
    Escherichia coli O104:H4 was associated with a severe foodborne disease outbreak originating in Germany in May 2011. More than 4000 illnesses and 50 deaths were reported. The outbreak strain was a typical enteroaggregative ...
  • Laird, Robert A.; Schamp, Brandon S. (Arts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2016-06-14)
    Intransitive competition occurs when competing strategies cannot be listed in a hierarchy, but rather form loops – as in the game Rock-Paper-Scissors. Due to its cyclic competitive replacement, competitive intransitivity ...
  • Pyle, Gregory; Mirza, Reehan S. (Taylor & FrancisArts and ScienceDepartment of BiologyNipissing UniversityUniversity of Lethbridge, 2007)
    Chemosensation is one of the oldest and most important sensory modalities utilized by aquatic animals to provide information about the location of predators, location of prey, sexual status of potential mates, genetic ...
  • Zohouri, Mohammad Ali; Pyle, Gregory; Wood, Chris M. (ElsevierArts and ScienceDepartment of BiologyMcMaster UniversityUniversity of Lethbridge, 2001)
    The effects of chronic exposure to waterborne Cd and elevated dietary Ca, alone and in combination, were examined in juvenile rainbow trout, Oncorhynchus mykiss. Fish were chronically exposed to 0.05 Žcontrol. or 2.56 g ...
  • Bilichak, Andriy; Ilnytskyy, Yaroslav; Woycicki, Rafal; Kepeshchuk, Nina; Fogen, Dawson; Kovalchuk, Igor (Frontiers MediaArts and ScienceDepartment of Biological SciencesLethbridge Research CentreUniversity of Lethbridge, 2015)
    Plants are able to maintain the memory of stress exposure throughout their ontogenesis and faithfully propagate it into the next generation. Recent evidence argues for the epigenetic nature of this phenomenon. Small RNAs ...
  • Migicovsky, Zoë; Kovalchuk, Igor (Frontiers MediaArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2012)
    Angiosperms do not contain a distinct germline, but rather develop gametes from game-tophyte initials that undergo cell division.These gametes contain cells that give rise to an endosperm and the embryo. DNA methylation ...
  • Hudson, Andrew J.; Moore, Ashley N.; Elniski, David; Joseph, Joella; Yee, Janet; Russell, Anthony G. (Oxford University PressArts and ScienceDepartment of Biological SciencesAlberta RNA Research and Training InstituteUniversity of LethbridgeTrent University, 2012)
    Non-coding RNAs (ncRNAs) have diverse essential biological functions in all organisms, and in eukaryotes, two such classes of ncRNAs are the small nucleolar (sno) and small nuclear (sn) RNAs. In this study, we have ...
  • Hargreaves, A.L.; Bailey, S.F.; Laird, Robert A. (Arts and ScienceDepartment of Biological SciencesQueen's UniversityAarhus UniversityUniversity of Lethbridge, 2016-06-14)
    Dispersal ability will largely determine whether species track their climatic niches during climate change, a process especially important for populations at contracting (low-­latitude/low-­elevatio ...
  • Adams, Rachael V.; Burg, Theresa M. (Public Library of ScienceArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2015)
    Habitat loss and fragmentation can affect the persistence of populations by reducing connectivity and restricting the ability of individuals to disperse across landscapes. Dispersal corridors promote population connectivity ...

    Both morphological and genetic evidence support a hybridization event between a Boreal Chickadee (Poecile hudsonicus) and a Black-capped Chickadee (Poecile atricapillus) in Atlantic Canada. Plumage of the hybrid was ...
  • Pulgararín-R, Paulo C.; Burg, Theresa M. (Public Library of ScienceArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2012)
    The glacial cycles of the Pleistocene have been recognized as important, large-scale historical processes that strongly influenced the demographic patterns and genetic structure of many species. Here we present evidence ...
