Hematological Variation Associated With Altitude, Season, Sexual Activity And Body In The Uinta Ground Squirrel, Ralph Theodore Kinchloe
Hematological Variation Associated With Altitude, Season, Sexual Activity And Body In The Uinta Ground Squirrel, Ralph Theodore Kinchloe
Theses and Dissertations
Hematological comparisons were made on the Uinta ground squirrel (Citellus armatus) trapped at different altitudes and during vari ou s stages of seasonal activity in 1965 and 1966. Hematological variation due to sex, sexual activity and body weight were also analyzed. Ground squirrels were secured from the Mt. Timpanogos area near Provo, Utah County, Utah. Erythrocyte count, hematocrit, total blood hemoglobin, mean erythrocyte volume, mean erythrocyte hemoglobin and reticulocyte counts were measured using standard procedures; banding patterns of hemoglobin and serum proteins wer e determined by means of electrophoresis with polyacetate strips.
Physiological Variations In The Uinta Ground Squirrel (Citellus Armatus) In Relation To Seasonal Activity And Altitude, Marden Reed Kohler
Physiological Variations In The Uinta Ground Squirrel (Citellus Armatus) In Relation To Seasonal Activity And Altitude, Marden Reed Kohler
Theses and Dissertations
The purpose of this investigation was to study the weight changes of selected internal organs to determine possible physiological variation occurring at six different altitudes ranging from 5,800 to 8,500 feetand during the summer season. This report was limited to the study of changes in the adrenal glands, kidneys, testes, heart and intestines. Electrocardiogram, heart and respiration rates were investigated also. These changes were statistically analyzed to determine possible seasonal differences along with any significant changes occurring at different elevations. The results of the study should in part overcome the lack of current experimental data for Citellus armatus.
A Study Of The Golden-Mantled Ground Squirrel (Citellus Lateralis) In A Sagebrush-Grass Community, Dennis E. Peterson
A Study Of The Golden-Mantled Ground Squirrel (Citellus Lateralis) In A Sagebrush-Grass Community, Dennis E. Peterson
Theses and Dissertations
Golden-mantled ground squirrels (Citellus lateralis Say) typically inhabit coniferous forest regions, but they occasionally occur in desert shrub habitats. The principal purpose of this study was to observe activities of mantled squirrels in a sagebrush community, and to ascertain factors which contribute to their success in an unusually arid habitat. Squirrels of this community belong to the subspecies C. l. lateralis; however, intergradation between typical C. l. lateralis and C. l. castanurus is evident. This community is in the Wasatch Mountains at an elevation of 5,750 feet, and in the Upper Sonoran Zone. These three conditions were not previously recorded …
