The Effect of Capture on Ranging Behaviour and Activity of the European Roe Deer Capreolus capreolus
2009
Locating and monitoring animals using tracking devices is a method commonly used for many taxa to study characteristics such as home-range size, habitat selection, movement patterns and other aspects of ranging behaviour. Fitting such devices requires the capture and handling of the study organism and researchers must then assume that a monitored animal behaves in a ‘normal’ way. We investigated whether the capture and handling of roe deer Capreolus capreolus induced behavioural alterations. In particular, we expected that the roe deer would exhibit a ‘seeking a refuge and waiting before returning’ strategy immediately after release, taking shelter far from the capture scene, in closed habitat, and exhibiting a reduced activity level. We evaluated the effect of capture and handling on 112 roe deer equipped with GPS collars, during a period of 50 days after release. We compared the first 10 days after release with the subsequent days for the following behavioural parameters: distance to the barycentre of t...
