    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 ...
  • Burg, Theresa M.; Lauff, Randolph F. (Ottawa Field-Naturalists' ClubArts and ScienceDepartment of Biological SciencesUniversity of LethbridgeSt. Francis Xavier UniversityNova Scotia Museum of Natural History, 2012)
    An anomalously large and coloured egg was found within a clutch of the Northern Saw-whet Owl (Aegolius acadicus) in Nova Scotia; all other eggs of the clutch were within the normal size and colour range for the species. ...
  • Weisbord, C.D.; Callaghan, D.T.; Pyle, Gregory (National Research Council of CanadaArts and ScienceDepartment of BiologyUniversity of LethbridgeLakehead University, 2012)
    Chemical communication governs a diversity of life processes in aquatic organisms. Crayfish use chemoreception during reproduction, social hierarchy formation, predation avoidance, and resource localization. Fish eggs ...
  • Rood, Stewart B.; Mahoney, John M. (Lethbridge, AB : University of Lethbridge, 1991Faculty of Arts and ScienceBiological SciencesUniversity of Lethbridge, 1991-02)
    Proceedings of the University of Lethbridge conference, May 4 to 6, 1990.
  • Bain, John; Flanagan, June; Kuijt, Job ([Lethbridge, Alta : University of Lethbridge] ; Lethbridge, Alta. : distributed by University of Lethbridge Digital Herbarium, 2014Arts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2014)
  • 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 ...
  • 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 ...
  • Lait, Linda Amy; Lauff, Randolph F.; Burg, Theresa M. (Ottawa Field-Naturalists' ClubArts and ScienceDepartment of Biological SciencesUniversity of LethbridgeSt. Francis Xavier UniversityMemorial University of Newfoundland, 2012)
    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 ...
  • Babenko, Olena; Golubov, Andrey; Ilnytskyy, Yaroslav; Kovalchuk, Igor; Metz, Gerlinde A. S. (Public Library of ScienceArts and ScienceDepartment of Biological SciencesCanadian Centre for Behavioural NeuroscienceUniversity of LethbridgeUniversity of Calgary, 2012)
    Stress represents a critical influence on motor system function and has been shown to impair movement performance. We hypothesized that stress-induced motor impairments are due to brain-specific changes in miRNA and ...
  • Kovalchuk, Igor; Walz, Paul; Thomas, James; Kovalchuk, Olga (Public Library of ScienceArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2013)
    Bacterial infection has been linked to carcinogenesis, however, there is lack of knowledge of molecular mechanisms that associate infection with the development of cancer. We analyzed possible effects of the consumption ...
  • Swift, Lucy H.; Golsteyn, Roy M. (M D P I A GArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2014)
    When a human cell detects damaged DNA, it initiates the DNA damage response (DDR) that permits it to repair the damage and avoid transmitting it to daughter cells. Despite this response, changes to the genome occur and ...
  • Adams, Rachael V.; Lazerte, Stefanie E.; Burg, Theresa M. (Arts and ScienceDepartment of Biological SciencesUniversity of LethbridgeUniversity of Northern British Columbia, 2016-08-08)
    Variation in landscape features influence individual dispersal and as a result can affect both gene flow and genetic variation within and between populations. The landscape of British Columbia, Canada, is already highly ...
