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 …

Occupancy dynamics, personality, & behavior of Franklin's Ground Squirrel in agricultural landscapes
… movement of Poliocitellus franklinii (Franklin’s ground squirrels), a grassland species of conservation concern, at multiple scales in agricultural landscapes in the Midwestern United States. First, I investigated the relative influence of habitat quality, area, and connectivity on patterns of …

Some Life History and Ecological Activites of the Richardson Ground Squirrel In South Dakota
… range rodents such as the prairie dog and the ground squirrel existed undisturbed and unmolested except by their natural predators. With the advent of cultivated crops, the range herbivores found a new and tasty source of food. Among these primary consumers which took advantage of man’s …

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 …

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, …

Monitoring Squirrels from the Sky: Applications of Uncrewed Aerial Systems-Based Bioacoustic and Vegetation Monitoring Regimes for Mohave Ground Squirrel
… understand the areas occupied by the Mohave ground squirrel (Xerospermophilus mohavensis) through the application of uncrewed aerial systems-based (henceforward UAS or drones) bioacoustic monitoring. The Mohave ground squirrel (MGS) is a threatened species under the California Endangered …

Amiloride-sensitive components of sodium transport in guinea pig red blood cells: A cause of imbalance of sodium ion at low temperature
… cells of guinea pig is faster than in those of ground squirrel during cold storage at 5$\sp\circ$C in vitro and amiloride can partially inhibit the accumulation. Also, amiloride-sensitive Na influx in guinea pig red cells is known to be larger at 20$\sp\circ$C than at 37$\sp\circ$C.
