    Exploring Innovation and Behavioral Flexibility in Captive Carnivores

    The highly specialized order Carnivora, while underrepresented in the comparative cognition literature, faces diverse ecological and social constraints. Thus, species and individuals should differ in behaviors associated with cognitive abilities, facilitating the successful navigation of these challenges. Behavioral flexibility was measured in 80 individuals of 17 species through personality assessments predicting success on a multi-access puzzle box (MAB) and behaviors associated with cognition on both a MAB and an Impossible Task. At the species level, social species were significantly more persistent on the MAB, and smaller body mass and higher encephalization was associated with persistence and latency to success on the MAB. Within species, on the individual level, there were several significant differences in behaviors between the sexes, ambassador versus exhibit animals, and wild versus captive-born species in the behavioral trait assessments, and on the MAB and Impossible Task. No significant differences existed between individuals of different ages or species rated differently on the IUCN scale or in brain volume on the MAB. This dissertation contributes to the growing field of animal cognition through the first use of personality assessments predicting problem-solving success on an MAB, the largest and most inclusive sample of felids on an MAB, and the first use of an Impossible Task in non-domesticated felids.
