Is abdominal implantation of devices a good alternative to external attachment? A comparative study in Adelie penguins
Abstract 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 behaviour of free-ra...
