Intra- and inter-familial behaviour of Glaucomys volans (Rodentia) following parturition

Intra- and inter-familial behaviour of Glaucomys volans (rodentia) following parturition.

The remarkably strong propensity in female flying squirrels (Glaucomys volans) for retrieving their young has been noted by several naturalists . In one instance (Stack 1925) a female climbed up the pant-leg of an observer who had removed the young from a nest; she took four babies from the observer's hand and carried each of them to another tree cavity. During my own field work I have often ob...

The chromosomes of the New World flying squirrels (Glaucomys volans and Glaucomys sabrinus) with special reference to autosomal heterochromatin.

There are two species of New World flying squirrels included in the genus Glaucomys: G. sabrinus, the northern flying squirrel, and G. volans, the southern flying squirrel. During a study of local rodents around Hanover, New Hampshire, several flying squirrels were caught and their chromosomes were analyzed. The occurrence, in this region, of both species allowed a comparative study of their re...

Effects of southern flying squirrels Glaucomys volans on red-cockaded woodpecker Picoides borealis reproductive success

Anecdotal data gathered from many populations suggest that southern flying squirrel (SFS, Gluucomys volans) use of the endangered red-cockaded woodpecker’s (RCW, Picoides borealis) nest and roost cavities may negatively affect RCW populations. We conducted a controlled experiment to determine the effects of SFSs on RCW reproductive success. During the 1994 and 1995 breeding seasons, SFSs were r...

Inter-familial and intra-familial phenotypic variability in three Sicilian families with Anderson-Fabry disease

BACKGROUND Anderson-Fabry disease (AFD) is an inborn lysosomal enzymopathy resulting from the deficient or absent activity of the lysosomal exogalactohydrolase, α-galactosidase A. This deficiency, results in the altered metabolism of glycosphingolipids which leads to their accumulation in lysosomes, thus to cellular and vascular dysfunction. To date, numerous mutations (according to recent data...
