Thermal and behavioural responses of moose to chemical immobilisation from a helicopter
Instrumentation and sample collection for wildlife research and management may require chemical immobilisation of animals, which may entail physiological and behavioural efects on them. It is therefore important to evaluate the immobilisation protocols to reduce the risk of mortality and morbidity o...

Instrumentation and sample collection for wildlife research and management may require chemical immobilisation of animals, which may entail physiological and behavioural efects on them. It is therefore important to evaluate the immobilisation protocols to reduce the risk of mortality and morbidity of the handled animals and their populations. Using a multi-sensor approach, we assessed the short-term (<10 days) thermal and behavioural responses of 10 adult female moose (Alces alces) equipped with ruminal temperature loggers and GPS collars with accelerometers to helicopter-based chemical immobili sations. We investigated the body temperature (Tb), movement rates, and resting time before, during, and after recapture. Chemical immobilisations on average increased maximum Tb by 0.71 °C during the capture day, and imposed longer travel distances during the capture day and the two following days (3.8 and 1.8 km, respectively), compared to a 10-day reference period before the immobilisation.
