The adaptive utility of Richardson’s ground squirrel (Spermophilus richardsonii) short-range ultrasonic alarm signals
Richardson’s ground squirrels (Spermophilus richardsonii (Sabine, 1822)) produce audible (ca. 8 kHz) and (or) ultrasonic (ca. 48 kHz) alarm vocalizations that warn conspecifics of impending danger. Audible calls have a larger active space than ultrasonic calls because they travel farther, are louder, and contain frequencies to which conspecific and allospecific recipients are more sensitive. In...
متن کاملImpact of live trapping on stress profiles of Richardson's ground squirrel (Spermophilus richardsonii).
Researching the physiological ecology of natural populations requires an understanding of the impact of capture-induced stress because of its numerous effects on physiological processes. In many cases, initial blood samples to which comparisons are made are obtained well after capture and may differ markedly from free-ranging conditions. We examined the extent to which stress profiles of male R...

Physiol. 220(3) : 747-753. 1971. -A tissue-slice analysis showed no solute gradient of urea and sodium from the corticomedullary boundary through the papilla of torpid Columbian ground squirrels. Ground squirrels arousing normally from torpor and sacrificed 15 or 40 min after urine began to flow ...
متن کاملGeneric Revision in the Holarctic Ground Squirrel Genus Spermophilus
The substantial body of research on Holarctic ground squirrels amassed over the past century documents considerable variability in morphological, cytogenetic, ecological, and behavioral attributes in the genus Spermophilus F. Cuvier, 1825. Recent molecular phylogenetic studies suggest that the traditionally recognized genera Marmota Blumenbach, 1779 (marmots), Cynomys Rafinesque, 1817 (prairie ...
متن کاملEQUINE ENCEPHALOMYELITIS (Eastern and Western) SUMMARY Eastern and Western equine encephalomyelitis viruses belong to the genus Alphavirus of the family
Eastern and Western equine encephalomyelitis viruses belong to the genus Alphavirus of the family Togaviridae. Alternate infection of birds and mosquitoes maintain these viruses in nature. The disease occurs sporadically in horses and humans from mid-summer to late autumn. Horses and humans are tangential dead-end hosts. The disease in horses is characterised by fever, anorexia, and severe depr...
