ANECDOTE

Mass Collaring Revealed A Sea Of Data

  • Meg Crofoot collared ~25 baboons and recorded one GPS point per second for a month, yielding ~20 million GPS points and massive accelerometry data.
  • The collars let the team visualize every individual's movements simultaneously and reveal hidden group patterns.

  • Instead of a single leader, the troop formed amoeba-like shapes with multiple initiators and shifting influence.
