Acute Thermal and Stress Response in Moose to Chemical Immobilization
ABSTRACT Management and research of moose ( Alces alces ) in Alaska, USA, often require chemical immobilization; however, moose may be prone to capture‐induced hyperthermia while immobilized. We chemically immobilized moose with carfentanil citrate and xylazine hydrochloride to measure rump fat dept...

Additionally, we expected post‐capture body temperature would be a function of activity, time immobilized, and ambient temperature. As predicted, body temperature of wild moose was elevated 1 hour after capture (38.9°C, 95% CI = 38.7–39.1°C) but returned to baseline levels within 3 hours (38.0°C, 95% CI = 37.9–38.1°C); however, body temperatures then rose above baseline levels and remained elevated 12–48 hours post‐capture when movement rates were also elevated.
