Aggressiveness, boldness, and lateralization: an investigation of personality by sex and alternative male morph in Pelvicachromis pulcherDownload
Animal personality, patterns of behavior that are consistent across time and contexts, is a growing area of study and has been documented in a wide array of species. Some personality traits show sex differences. Recent work on the kribensis cichlid (Pelvicachromis pulcher) suggests that some...
Animal personality – defined as consistent differences in behaviour among individuals – is a growing field in behavioural ecology due to its demonstrated effects on fitness. However, the ontogeny of personality under natural conditions remains relatively unexplored. In this thesis, I examine the...
Legs IV of males in the family Tarsonemidae are highly modified to form thickened pincer-like appendages. Previous literature describes males using legs IV both to manipulate pharate females onto the males' genital capsule as well as to constrain the adult female's legs during mating. We observed...
Raw data: changes in personality associated with maturation and territory acquisition in the red squirrel
Raw data: changes in personality associated with maturation and territory acquisition in the red squirrelDownload
Raw dataset for 'changes in personality associated with maturation and territory acquisition in the red squirrel' (to be submitted to Proceedings of the Royal Society B: Biological Sciences)
Purpose: My aim in this thesis was to investigate the relationship between resident aggression towards care aides and quality of care in long-term care (LTC). Design: This is a paper-based thesis comprised of an introduction and overview, a critical review of the literature and an empirical...
Cerebral lateralization was once thought to be unique to humans, but is now known to be widespread among the vertebrates. Lateralization appears to confer cognitive advantages upon those that possess it. Despite the taxonomic ubiquity and described advantages of lateralization, substantial...
The effect of sex, size and habitat on the incidence of puncture wounds in the claws of the porcelain crab Petrolisthes cinctipes (Anomura: Porcellanidae)Download
Many porcelain crabs have an unusual claw (cheliped) form that is broad, flat and thin. This seemingly flimsy form suggests claws may be used more for display than for feeding or aggressive interactions. However, in the flat-topped porcelain crab Petrolisthes cinctipes, one of the most abundant...
