Effects of provisioning bottlenose dolphins in Cockburn Sound: injuries, entanglements, and changes to ranging and social behaviours

Updated: 2021-08-04

Unpublished data and analyses from Rebecca Donaldson (1993-1997) and original data collected for the thesis (2000-2003) from Cockburn Sound were used to: 1) evaluate the link between high-risk behaviour by dolphins during provisioning interactions and rates of human-induced injury; 2) contrast the behaviour of known individuals before and after they engaged in provisioning interactions; and 3) examine the incidence of unregulated provisioning interactions within a population-level context in which the baseline demographic parameters were known.
