EXPERIMENTAL POPULATION SUPPRESSION OF RICHARDSON'S GROUND SQUIRRELS (Spermophilus richardsonii) IN ALBERTA
Richardson's Ground Squirrel is one of the most economically harmful rodents in east central Alberta. In an effort to develop an effective, safe, economical and practical method of long-term population control over large areas, experimental f i e l d t e s t i n g was begun in 1970 to evaluate a variety of potential control techniques. Although tests w i t h a machine b a i t applicator proved ...
متن کاملExperimental infection of Richardson's ground squirrels (Spermophilus richardsonii) with attenuated and virulent strains of Brucella abortus.
A previous investigation of the safety of Brucella abortus strain RB51 (sRB51) in various nontarget species suggested that Richardson's ground squirrels (Spermophilus richardsonii) may develop persistent infections when orally inoculated with the vaccine. In the present study, sRB51, B. abortus strain 19 (s19), and virulent B. abortus strain 9941 (s9941) were administered orally to Richardson's...

متن کاملAge-specific resource investment strategies: evidence from female Richardson’s ground squirrels (Spermophilus richardsonii )
To avoid a possible cost to their future survival and/or reproduction, individuals must balance their somatic and reproductive investments. The van Noordwijk and De Jong model of resource investment predicts that investments into reproduction and soma can vary among individuals of a population based on the variation in the total amount of energy that individuals acquire. With principal componen...
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...
