a) Longevity of all hamsters in the study.
b) Longevity of the poor, moderate and good hibernators in the study
a) control hamsters (mean = 812 days, median = 843 days)
b) experimental hamsters (mean = 914 days, median = 884 days)
(a) Average longevity for bat species that do and do not hibernate.
(b) Average change in longevity between phylogenically independent comparisons in which hibernation was acquired.
Hibernation is not continuous!
There are cycles of hibernation and short awakening
(every week in ground squirrels)
Hibernation signals (darkness) may be sufficient!
A) Reproductive success of long-day (LD), short-day (SD) and short-day pinealectomized (SD-PX) females expressed as the percentage of females mated at 9 mo of age that delivered live litters.
B) Mean + SEM live litter size at birth and weaning.
