Distances travelled, night-roosting time and statistical comparisons for 14 upstream and 9 downstream <i>Myotis daubentonii</i> males radiotracked at the Abruzzo, Lazio and Molise National Park and its buffer zone, in Central Italy.

We considered both the straight distance from the roost to the farthest location reached on a given night and the length of the actual route covered by bats following the waterways; inactivity time is the total amount of time a bat spent inactive from emergence to sunrise.
