Early auditory experience and the ontogeny of alarm-call discrimination in Belding's ground squirrels (Spermophilus beldingi).
Because young ground squirrels are vulnerable to predation, selection would favor the early ability to respond to alarm calls. This requires discrimination of classes of alarm calls from each other as well as from non-alarm calls. Pre-emergent auditory experience may influence the development of discrimination. As a means of determining when Belding's ground squirrels (Spermophilus beldingi) ca...
متن کاملDevelopmental and geographic variation in stress hormones in wild Belding's ground squirrels (Spermophilus beldingi).
Extensive research has been conducted on the role of glucocorticoids in regulating growth, mobilizing energy, responding to stressors and modulating learning and memory. However, little is known about the production of corticoids during early development in free-living animals, particularly during sensitive periods of acquisition of important behaviors. In a four-year study of Belding's ground ...
متن کاملDevelopment of alarm-call responses in Belding's ground squirrels: the role of dams
Experiences with adult conspecifics can influence the ontogeny of species-typical behaviours in naive young of many species. Two processes of influence, direct and indirect, are proposed to describe the effect of adult behaviours on juvenile development. In Belding's ground squirrels, Spermophilus beldingiexposure to adults experienced with responding to alarm calls may affect how juveniles res...
متن کاملSpermophilus xanthoprymnus (Rodentia: Sciuridae)
Spermophilus xanthoprymnus (Bennett, 1835), the Asia Minor ground squirrel, is a group-living, diurnal, obligately hibernating marmotine squirrel. It inhabits the steppes and alpine meadows throughout central lowland and eastern highland Anatolia and adjacent Armenia and northwestern Iran. Its preferred elevation appears to range from about 800 to 2,900 m. The species displays sexual dimorphism...
متن کاملBile constituents in hibernating golden-mantled ground squirrels (Spermophilus lateralis)
BACKGROUND Golden-mantled ground squirrels (S. lateralis) are anorexic during the winter and survive by exploiting hibernation to reduce energetic demands. The liver normally plays a critical role in fueling and regulating metabolism and one might expect significant changes in hepatobiliary function with hibernation. We analyzed bile collected from animals in summer, animals in winter that were...
