Factors affecting male-male competition in thirteen-lined ground squirrels

Why Male Ground Squirrels Disperse

When they are about two months old, male Belding’s develop the idea that natal dispersal, like other behaviors ground squirrels (Spermophilus beldingi) leave the burrow and phenotypic attributes, can be understood from mulwhere they were born, never to return. Their sisters tiple, complementary perspectives. Separating these levbehave quite differently, remaining near home throughels of analysi...

Up-regulation of Long Non-coding RNA TUG1 in Hibernating Thirteen-lined Ground Squirrels

Mammalian hibernation is associated with multiple physiological, biochemical, and molecular changes that allow animals to endure colder temperatures. We hypothesize that long non-coding RNAs (lncRNAs), a group of non-coding transcripts with diverse functions, are differentially expressed during hibernation. In this study, expression levels of lncRNAsH19 and TUG1 were assessed via qRT-PCR in liv...

Melatonin receptor signaling contributes to neuroprotection upon arousal from torpor in thirteen-lined ground squirrels.

The brain of mammalian hibernators is naturally protected. Hibernating ground squirrels undergo rapid and extreme changes in body temperature and brain perfusion as they cycle between lengthy torpor bouts and brief periods of euthermia called interbout arousals (IBAs). Arousal from torpor to IBA occurs rapidly, but there is no evidence of brain injury accompanying this extreme physiological tra...

Regulation of the mTOR signaling network in hibernating thirteen-lined ground squirrels.

For many small mammals, survival over the winter months is a serious challenge because of low environmental temperatures and limited food availability. The solution for many species, such as thirteen-lined ground squirrels (Ictidomys tridecemlineatus), is hibernation, an altered physiological state characterized by seasonal heterothermy and entry into long periods of torpor that are intersperse...
