Approach to wolf study

As a result of many centuries during which wolves were pursued and killed by man in order to be totally exterminated, the wolves of today have become very cautious and hardly noticeable. The studies must therefore resort to indirect methods of data collection through indications of the wolf\'s presence and passing (traces, excrements, prey rests). Most of the data on the wolf\'s movement, habitat use and activities may be collected by telemetric monitoring. This method of studying the wildlife consists of capturing individuals alive and their subsequent release in the wild after marking them in one or more ways to facilitate monitoring of their movement and natural behaviour. The most appropriate and proven method of marking the wolves so as to be able to study their biology is radio-collaring. A portable radio-receiver and an antenna are used to detect a signal which enables determination of the location and activity of the animal monitored. Since not long ago these collars for monitoring are equipped with a GPS device and a GSM addition sending data by SMS directly to the researcher\'s computer.
