hAGS (hibernating AGS), eAGS (euthermic AGS), laAGS (late arousal AGS), Female (F), male (M), adult (A), juvenile (J).
Used to study effect of hibernation.
Used to study effect of arousal following hibernation.
laAGS were treated with saline prior to arousal.
3 of 5 AGS that hibernated. 2 of 5 AGS did not hibernate prior to tissue collection.
Euthanized before onset of hibernation.
