Status and Distribution of Franklin's and Richardson's Ground Squirrels in Eastern South Dakota
… mammal species such as the Richardson’s ground squirrel (Urocitellus richardsonii) and Franklin’s ground squirrel (Poliocitellus franklinii) have suffered declines in abundance and distribution throughout their range due to loss of grassland. However, little is known about the …

Determining parentage and the effects of relatedness on play partner preference in Belding's ground squirrels
… investigated 1) multiple paternity in Belding’s ground squirrels (<em>Urocitellus beldingi</em>) and 2) social partner preferences in juvenile <em>U. beldingi</em>. Prior work with blood allozymes demonstrated multiple paternity in <em>U. beldingi</em> litters. I evaluated paternity using …

Seasonal patterns in body temperature and behaviour in Cape ground squirrels, Xerus inauris, living in a semi-arid environment
… the abdominal cavities of 16 free-ranging Cape ground squirrels, Xerus inauris, to investigate seasonal body temperature patterns. Data loggers recorded body temperature at 5-min intervals while microclimate variables were recorded in situ at 15 minute intervals. The behaviour of the study …

Thyroid Hormones and the Onset of Hibernation in the 13-Lined Ground Squirrel, Spermophilus Tridecemlineatus
… hibernation, or delay its onset. Thirteen-lined ground squirrels, Spermophilus tridecemlineatus, (n=7 per treatment) were given propylthiouracil (PTU: 0.01%) in their drinking water to block thyroid function, in combination with a long photoperiod or naturally decreasing photoperiod, and either …

Food Habits and Energy Utilization of Badgers
… two energy-balance and three digestion trials. Ground squirrels, mice and rabbits were found to be the most important mammal foods eaten. Birds and eggs were only eaten during spring and summer. Toads and grains were important fall foods. Insects were eaten throughout the year but usually only …

Use of Eastern South Dakota Shelterbelts By Nesting Birds of Prey
… Peromyscus spp. in great horned owl pellets, ground squirrels (Spermophilus spp.) and birds in red-tailed hawk pellets, ground squirrels and rabbits (Lagopmorpha) in Swainson’s hawk pellets, and insects, birds, and Microtus spp. in American kestrel pellets. Observations on raptor perch …

Demographics and Transfer of Escherichia coli Within Bos taurus Populations
… coli</em> isolates from cattle and cohabitating ground squirrels were compared through a new method of bacterial strain typing called pyroprinting. Bulls from the Cal Poly Bull Test were sampled every summer from May to September when around 200 bulls from ranches across California are housed …

Reproductive Delay In The Female Cape Ground Squirrel (xerus Inauris)
The Cape ground squirrel, Xerus inauris, is a highly social cooperative breeder that forms groups containing multiple breeding females. While the distribution of reproduction among group members is fairly even (i.e. exhibits low reproductive skew), previous studies of Cape ground squirrels suggest …

Hibernation is super complex: dynamics of electron transport system supercomplexes
… mitochondria from rats and thirteen-lined ground squirrels (TLGS) in different hibernation states and measured mitochondrial respiration. I extracted mitochondrial proteins using two detergents of different strengths, and quantified SC abundance using 2-dimensional gel electrophoresis and …

Temperature-dependent alterations of brown adipose tissue metabolism during hibernation in the thirteen-lined ground squirrel, <i>Ictidomys tridecemlineatus</i>.
… mitochondria isolated from torpid thirteen-lined ground squirrels were suppressed by up to 62% compared with rates from individuals that aroused to interbout euthermia (IBE), when measured at 37°C. At 10°C, however, these rates did not differ between torpor and IBE. Contrary to these results, …
