Aldabra giant tortoise (Aldabrachelys gigantea) high resolution movement path on Round Island (Mauritius)

<div>Aldabra giant tortoise (<i>Aldabrachelys gigantea</i>) 14-day dead-reckoned movement track (1 Hz resolution) obtained from 40Hz accelerometer and magnetometer data, collected using the 'Daily Diary' tag (Wildbyte Technologies Ltd, Swansea University, UK) and GPS data collected twice daily during daytime (am & pm). The data are part of the larger project "Tracking giant tortoise behaviour to manage re‐wilding" led by Durrell Conservation Trust and Mauritian</div><div>Wildlife Foundation, with biologging data collection led by Swansea University and Nik Cole. Data collection and dead-reckoning was done by James Redcliffe, using the Framework 4 software, with data pre-processing using the DDMT software (Wildbyte Technologies Ltd). Location data are projected to UTM40. We thank the National Parks and Conservation Service, Ministry of Agro-Industry for permission to access Round Island and undertake this research through the Tortoise Rewilding Project.</div

An example plot of uptake against <i>ODBA</i> (black circles) and <i>VeDBA</i> (grey triangles) over the duration of the trial following removal of the points above the participant's anaerobic threshold.

Dynamic body accelerations (<i>ODBA</i> – circles, and <i>VeDBA</i> –crosses) from straight- versus skew-mounted accelerometers (for details see text).

<p>Each point denotes a mean value derived from a three-minute trial of a participant moving at one particular speed below the lactate threshold. Data from all participants are included.</p

Heave (continuous line), sway (dotted line) and surge (dashed line) acceleration axes displayed graphically over one stride (from each leg) during walking (i) and running (ii).

Relationship between mean <i>ODBA</i> and mean <i>VeDBA</i> (means taken for each running speed) for a test participant during a max test.

<p>Only data during the period when the participant did not exceed the ventilatory threshold (for definition see text) are included. as with all other participants, the relationship between <i>ODBA</i> and <i>VeDBA</i> was highly significant (<i>VeDBA</i> = 0.014+0.6418 <i>ODBA</i>, r² = 0.987, P<0.001).</p

Predicted difference between straight- and skew-mounted <i>ODBA</i> derived from recordings on a tri-axial accelerometer subjected to equal acceleration in the heave, surge and sway axes as a function of pitch, roll and yaw differences between straight and skew.

<p>Contour lines show 2.5% intervals.</p
