Lévy like patterns in the small-scale movements of marsupials in an unfamiliar and risky environment [PDF]

open access: yesScientific Reports, 9, 2737 (2019), 2019
We investigate the movement patterns of three different Neotropical marsupials in an unfamiliar and risky environment. Animals are released in a matrix from which they try to reach a patch of forest. Their movements, performed on a small spacial scale, are best approximated by L\'evy flights.
