Studies of personality and temperament in humans span many disciplines, although animal research is still relatively undeveloped. Research investigating stable individual differences in marine mammals has been limited, and to date there have not been any studies with beluga whales. As an ongoing longitudinal study, seven beluga calves, housed at SeaWorld San Antonio, were videotaped throughout their first two years of life. Four videos were selected from archived video recordings for each calf from the following nine phases: newborn phase (month 1), Q1 (month 2-3), Q2 (month 4-6), Q3 (month 7-9), Q4 (month 10-12), Q5 (month 13-15), Q6 (month 16-18), …

Legislative and market initiatives are requiring that gestating sows move from individual housing to group settings. Little information is known about coping styles of individual sows in these more socially complex environments and thus the impact of different behavioral strategies on sow reproductive success and efficiency was investigated. The movements of 70 sows during periods of reintroduction into large pen gestational housing following insemination was measured with a commercially available system that tracked animal location and accelerations. Principle component analysis (PCA) was used to establish composite variables characterizing each animal’s behavioral response to social reintroduction and revealed the presence of …
