Heart rates in the captive, free-ranging beaver

Seasonal and diel variation in body temperature and heart rate of the Eurasian beaver

“…HR was lower during day me when beavers rested in the lodge and increased during the evening, remaining elevated throughout the night, in line with ndings from cap ve beavers (Swain, Gilbert & Robine e 1988) and in accordance with the beavers' crepuscular and nocturnal ac vity pa ern (Swinnen, Hughes & Leirs 2015;Bartra Cabre et al 2020).…”

Comparison of Isoflurane and Sevoflurane for Anesthesia in Beaver

“…This could mean that the gases did not cause much irritation or it could be that animals were stressed from handling and we were unable to accurately assess the ease of induction. Heart rates for free-ranging beaver range from 60-70 bpm (resting) to 110-120 bpm (active) (Gilbert and Gofton, 1982;Swain et al, 1988). Beaver anesthetized with isoflurane and sevoflurane initially had heart rates similar to active beaver (110-120 bpm) which decreased to about 80-90 bpm by the end of the surgery (Fig.…”

Diving behavior in a free‐living, semi‐aquatic herbivore, the Eurasian beaver Castor fiber

“…However, beavers have a suite of specialized morphological (thick fur, adipose tissue; Novak, ), physiological (e.g., bradycardia, peripheral vasoconstriction, local heterothermy, Swain et al., ; MacArthur & Dyck, ), and behavioral adaptations that enable them to operate in cold water. The latter may include spending more time on land or inside the lodge (Nolet & Rosell, ; Smith et al., ) or the selection of food rich in polyunsaturated fatty acids, which improve membrane functionality at low temperatures (Hazel, ) and comprise a major part of the adipose tissues of beavers (Zalewski, Martysiak‐Żurowska, Chylińska‐Ptak, & Nitkiwicz, ).…”
