    Three adaptive hypotheses have been proposed to explain the link between the human leucocyte antigen (HLA) genes, health measures and facial attractiveness: inbreeding avoidance, heterozygote advantage and frequency-dependent ...
  • Dostie, Marcus Jack (Lethbridge, Alta. : University of Lethbridge, Dept. of GeographyArts and ScienceDepartment of GeographyDepartment of Psychology, 2014)
    A major limiting factor in the study of animal movement is the ability to collect affordable high resolution spatial data. Tracking data often requires interpolation; this research will focus on determining the amount of ...
  • Norman, Kerri M. (Lethbridge, Alta. : University of Lethbridge, Dept. of PsychologyArts and ScienceDepartment of Psychology, 2014)
    Research has shown that unlike wolves, dogs do not form stable packs and so do not function within a social hierarchy (Bradshaw, 2011). Therefore it is not clear that rolling onto the back can be readily interpreted as ...
  • Pasternak, Graham M. (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology, c2011Arts and ScienceDepartment of Psychology, 2011)
    Narrow riparian woodlands along non-perennial streams have made it possible for vervet monkeys to penetrate the semi-arid karoo ecosystem of South Africa, while artificial water points have more recently allowed these ...

    Self-directed behaviours (SDB) were recorded as a behavioural indicator of arousal in free-ranging vervet monkeys (Chlorocebus aethiops) inhabiting the Klein Karoo of South Africa. Measurement of SDB allowed for changes ...

    Does evolutionary theorizing have a rold in psychology? This is a more contentious issue than one might imagine, given that, as evolved creatures, the answer must surely be yes. The contested nature of evolutionary ...
  • Lucas, Miranda (Lethbridge, Alta. : University of Lethbridge, Dept. of PsychologyArts and ScienceDepartment of Psychology, 2014)
    Too much uncertainty in the world you live in can cause undue stress. Not knowing where to find your next meal or the prospect of being eaten at any moment are two examples. During aggressive encounters, creating uncertainty ...
  • Takahashi, April D. (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology, c2012Arts and ScienceDepartment of Psychology, 2012)
    This thesis offers an alternative to the conventional ‘social intelligence’ hypothesis: that the complexity of primate group emerges from dynamic, short term variation in partner availability and quality and that primate ...
  • Sashaw, Jessica Joan Hayden (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology, c2012Arts and ScienceDepartment of Psychology, 2012)
    I studied free-ranging vervet monkeys (Chlorocebus aethiops) in South Africa using focal animal sampling to test current theories of reproduction and maternal investment. Mothers cope with the energetic costs of lactation ...
  • Matlock, Alena; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology, c2013Arts and ScienceDepartment of Psychology, 2013)
    This study explores the effect of changing ecological conditions on female social organization among free-ranging vervet monkeys (Cholorocebus aethiops pygerythrus) in the Klein Karoo, South Africa. Comparison was made ...

    Large-scale interspecific studies of mammals ranging between 0.04–280 kg have shown that larger animals walk with more extended limb joints. Within a taxon or clade, however, the relationship between body size and joint ...
  • Thomas, Brittany L; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Psychology, c2013Arts and ScienceDepartment of Psychology, 2013)
    Vervet monkeys (Chlorocebus pygerythrus) are generally described as a territorial species, though variations in territoriality have been observed. This research examined the impact of high popula ...

    This thesis explores the female social structure of free ranging vervet monkeys and how social structure affects spatial positioning of individuals in the troop. The effect of dominance hierarchies on female grooming ...
  • Freeman, Natalie J (Lethbridge, Alta. : University of Lethbridge, c2012Arts and ScienceDepartment of Psychology, 2012)
    The permanent coresidence of males within a troop is unusual but occurs in vervet monkeys. Several hypotheses have been projected to explain the coexistence of male vervets (predation risk, breeding season length) but these ...
