Allele Model

Abstract I derive several properties of the model proposed by Gavrilets for maternal selection at a single diallelic locus. Most notably, (i) stable oscillations of genotype frequencies (i.e., cycling) can occur and (ii) in the special case in which maternal effects and standard viability selection act multiplicatively, maternal selection effectively acts on maternally derived alleles only.

Periodic Arousals

The hibernation pattern of captive eastern chipmunks maintained under controlled conditions of light and temperature was examined. It was consistent with the view that hibernation results from an endogenous rhythm with a periodicity of about a year, probably temperature independent.Continuous recording from nest bottom temperature sensors was tested for the first time with this species and found to be more accurate than the sawdust technique for detecting arousals. It also provided useful information about trends in body temperature.The hypothesis that a shift in the temperature at which heat-producing responses are mobilized occurs during hibernation and that it is responsible for the pattern of periodic arousals, is discussed in relation to the observations made.
