Fig. 3From: Using pseudo-absence models to test for environmental selection in marine movement ecology: the importance of sample size and selection strengthCharacteristics of observed blue shark tracks. a Step length distribution (median 32.7 km), b turning angle distribution (median 0.0\(^\circ\)), c step length as a function of turning angle. Color of panel c mimics the density of data points in the turning angle-step length space: yellower areas have a higher density of data pointsBack to article page
