Abstract

This PhD investigates how animal-attached motion-sensitive electronic tags might create behavioural biomarkers for animal ‘state’. Such biomarkers could indicate good health, disease, and injuries as well as positive and negative affective states. Success could have widespread implications for the w...

Then, potential TDBBs for &#x2018;healthy&#x2019; turtles and those with gas emboli were created, with variance in body attitude, number of 45&#xB0; turns per hour and mean angular velocity per hour showing the most promise to differentiate the two groups. TDBBs were also explored for welfare, giving &#x2018;healthy&#x2019; turtles nutritional enrichment, demonstrating that enrichment procedures do not always affect captive animal behaviour. To consider welfare implications of captivity, the movement behaviour of free-living and managed-care loggerheads was compared to determine wild-type and captive behaviour overlap. Findings revealed significant differences in the variance in pitch, heading and absolute angular velocity as well as the number of turns per hour. The final research topic considered trajectory step length data (the distances travelled in between turns), derived from tags deployed on nine wild species, for informing enclosure size for captive animals. The findings revealed that existing enclosure size guidelines regularly only permitted animals to undertake a very small percentage (often less than 3 %) of the step lengths recorded from free-living conspecifics.
