Posters - 2024

Longitudinal observations of bottlenose dolphins (Tursiops truncatus) in managed care provide opportunities to assess behavior within different contexts, which may provide insights into individual and population wellbeing (e.g., Delfour et al., 2021; Serres et al., 2021). Since 2019, a longitudinal study on space use by bottlenose dolphins housed at a lagoon-based facility in Roatán, Honduras, has been conducted. Dolphin behavior and location data were collected with the goal of comparing behavior without humans present to varying contexts in which humans were present. The purpose of this descriptive study was to assess behaviors exhibited by dolphins in close proximity to a …
