Fig. 2From: Deriving movement properties and the effect of the environment from the Brownian bridge movement model in monkeys and birdsSpatial distribution of vervet monkey movement data. The Brownian bridge movement model takes the GPS fixes along the trajectories as input and is used to calculate a probability density distribution function of location (i.e. the utilisation distribution), but also a spatial distribution of a movement property like speed (red equals low, violet high speed). The black outline demarcates the 99 % volume isoplethBack to article page
