| Using New Lightweight GPS/GSM Transmitters to Monitor Movement and Predation of Eurasian Lynx (_Lynx lynx_) | |
| 2007 Conference Proceeding | |
Classic VHF radiotelemetry of animals with large home ranges is time consuming and there are often cases when the animals "disappear" due to unknown causes, one of which might be dispersion. Research is often hindered or even limited by national borders and/or inaccessible terrain. Use of GPS technology provides better efficiency in monitoring of movement of animals with higher precision even in remote areas and across national borders. Recent decreases of transmitters' weight made this technology feasible for telemetry of mid-sized animals. We will present preliminary results from a study of Eurasian lynx (_Lynx lynx_) using the new lightweight (285 g) Televilt Tellus GPS collar with remote GSM download technology. We captured a young female lynx on Sneznik plateau in Southern Slovenia and fitted her with the GPS/GSM collar. We tracked her movement in the northern Dinaric mountain range of Slovenia and Croatia and estimated success rate of GPS positioning in this very rugged karstic terrain. In addition, we will present methodology we used for locating prey remains and success rate of finding them, as well as preliminary data on prey preferences and predation rate of Eurasian lynx in Dinaric landscapes. |
