Predicting moose behaviors from tri-axial accelerometer data using a supervised classification algorithm
Abstract Background Monitoring the behavior of wild animals in situ can improve our understanding of how their behavior is related to their habitat and affected by disturbances and changes in their environment. Moose (Alces alces) are keystone species in their boreal habitats, where they are facing...
