Is abdominal implantation of devices a good alternative to external attachment ? A comparative study in Adélie penguins
International audience Bio-logging studies suffer from the lack of real controls. However, it is still possible to compare indirect parameters between control and equipped animals to assess the level of global disturbance due to instrumentation. In addition, it is also possible to compare the behavi...

This difference was due to a larger number of dives, reflecting a lower foraging ability or a higher food demand, and longer periods of recovery at the surface. These longer recovery periods were likely to be due to a reduced efficiency to ventilate at the surface, probably because the implanted devices pressurised adjacent organs such as air sacs.

Looking at our results, implantation appears more disadvantageous—at least for short-term deployment— than external equipment in Ade´lie Penguins, while this method has been described to induce no negative effects in long-term studies.

International audience Bio-logging studies suffer from the lack of real controls.

We instrumented Ade´lie Penguins (Pygoscelis adeliae) with internal or external time-depth recorders and monitored them in parallel with a control group during the first foraging trip following instrumentation.
