Starvation in hospital

Starvation induces genomic rearrangements and starvation-resilient phenotypes in yeast.

Evolution has shaped a wide variety of genomes across eukaryotic taxa. However, the forces that shape the genomes are generally unknown. Because organisms in nature commonly experience prolonged periods of nutrient depletion, we posit that diverse demographic, physiological, and genomic responses to starvation can occur. To test for these possibilities, we subjected replicate yeast populations ...

Activity in Starvation †

Deprivation of food, water, or individual nutrients usually causes an increase in the spontaneous running activity of the rate 9"'0, 170 2, U t, 2#,a8 although some exceptions have been reported.2,'7' ' The measurement of running activity has been used for investigations into motivation, for instance, as a measure of the hunger and thirst drives."90" Wald and Jackson considered the hyperactivit...

Starvation-Survival in Haloarchaea

Recent studies claiming to revive ancient microorganisms trapped in fluid inclusions in halite have warranted an investigation of long-term microbial persistence. While starvation-survival is widely reported for bacteria, it is less well known for halophilic archaea-microorganisms likely to be trapped in ancient salt crystals. To better understand microbial survival in fluid inclusions in ancie...

Extraordinary starvation resistance in

Ant colony mortality has not been sufficiently studied, even though it is crucial for understanding social insect population biology and can serve as an important model for general aging and mortality processes. Particularly, studies on proximate mechanisms on mortality and stress resistance of ant colonies are lacking. This study explores the long-term colony starvation resistance of the small...
