  • 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. ...
  • 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 ...

    We tested the hypothesis that segregation in wintering areas is associated with population differentiation in a sentinel North Pacific seabird, the rhinoceros auklet (Cerorhinca mono cerata). We collected tissue samples ...
  • 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 ...
  • Hindley, John A.; Graham, Brendan A.; Pulgarin-R., P. C.; Burg, Theresa M. (Nature Publishing GroupArts and ScienceDepartment of Biological SciencesUniversity of Lethbridgehttps://doi.org/10.1038/s41598-018-29982-7, 2018)
    Examining the factors that influence contemporary genetic patterns is important given the alarming rate at which natural environments are changing. In particular habitat fragmentation and climate change are expected to ...
  • Jensen, Ashley M.; O'Neil, Nicholas P.; Iwaniuk, Andrew N.; Burg, Theresa M. (WileyArts and ScienceCanadian Centre for Behavioural NeuroscienceDepartment of Biological SciencesUniversity of Lethbridgehttps://doi.org/10.1002/ece3.5112, 2019)
    The amount of dispersal that occurs among populations can be limited by landscape heterogeneity, which is often due to both natural processes and anthropogenic activity leading to habitat loss or fragmentation. Understanding ...
  • Dohms, Kimberly M.; Burg, Theresa M. (Peer J, LtdArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2014)
    The Eurasian or spotted nutcracker (Nucifraga caryocatactes) is a widespread resident corvid found throughout the Palearctic fromCentral Europe to Japan. Characterized by periodic bouts of irruptive dispersal in search ...

    Background: The biodiversity and distributions of terrestrial snails at local and regional scales are influenced by their low vagility and microhabitat specificity. The accessibility of large-bodied species and their ...
  • Dohms, Kimberly M.; Burg, Theresa M. (Public Library of ScienceArts and ScienceDepartment of Biological SciencesUniversity of Lethbridge, 2013)
    The genetic impact of barriers and Pleistocene glaciations on high latitude resident species has not been widely investigated. The Clark’s nutcracker is an endemic North American corvid closely associated with ...

    An increasing body of studies of widely distributed, high latitude species shows a variety of refugial locations and population genetic patterns. We examined the effects of glaciations and dispersal barriers on the popul ...
  • Burg, Theresa M. (University of the AzoresDepartment of BiologyQueen's University, 2005)
    Briefly explains the importance of using genetics to study seabirds.
  • Macfarlane, Colin B. A.; Natola, Libby; Brown, Mike W. (WileyArts and ScienceDepartment of Biological SciencesUniversity of Lethbridgehttps://dx.doi.org/10.1002/ece3.2524, 2016)
    Using a combination of mitochondrial and z- linked sequences, microsatellite data, and spatio- geographic modeling, we examined historical and contemporary factors influencing the population genetic structure of the purple ...
  • Hale, Marie L.; Burg, Theresa M.; Steeves, Tammy E. (Public Library of ScienceArts and ScienceDepartment of Biological SciencesUniversity of CanterburyUniversity of Lethbridge, 2012)
    One of the most common questions asked before starting a new population genetic study using microsatellite allele frequencies is ‘‘how many individuals do I need to sample from each population?’’ This question has previously ...
