Homing in and Ecology of the Southern Flying Squirrel Glaucomys volans in Southeastern Virginia

Abstract: A population of the southern flying squirrel Glaucomys volans in southeastern Virginia was examined for its homing ability. Nest boxes were used to capture the experimental animals and to evaluate homing. Squirrels returned home with high frequency from distances up to 1000 m. There was a significant association between low temperature and large aggregations of huddling squirrels in nest boxes. Holes used as feeding stations were never converted to primary nests.

Preliminary study on the ecology of trogopterus xanthipes

Abstract: The Complex-Toothed Flying Squirrel (Trogopterus xanthipes) is indigenous to China. This paper deals with its ecology as its living and habits, the changes of external morphology with ages, reproduction, growth and life-span. The observation were carried out both in field and in rearing conditions. The following results were approached. 1. In January, May and August, 1981, the temperature inside the nests in cliffs was never below 10℃ in winter,and never above 26℃ in summer, the relative humidity is usually at 39-89%. 2. During breeding, in a nest at house always only one squirrel, but we found two special cases: ( 1 ) One family lived at the same nest-box? ( 2 ) Two adult females and six young squirrels lived at the same nest -box peacefully. 3. The squirrels prefer the branches of Thuja orienialis and Pinus tabu-laeformis as their food. 4. The first mating occurs at two years old (to be preciss, at 22 months) individuals. 4-6 days after the beginning of oestrus, the external pudenda of the females change from white to damp red in colour, when the pudenda swell as large as a broad bean, the females begin to accepte mating. Pregnancy is about 78-89 days, and most of the young squirrels are born at noon or in afternoon, Litter size is 1-4,
