A conserved cold stress syndrome defines insect chill tolerance

This study identifies a conserved cold stress syndrome in insects, showing that hyperkalemia and ion homeostasis failure define chill tolerance across species and stress conditions.

Using thermal death time models to analyze cold stress resistance across Drosophila species

This study uses thermal death time models to analyze cold stress resistance across Drosophila species, finding that cold tolerance decreases with colder winter environments and that TDT curves provide predictive insights into insect cold resistance.

Chill tolerant Drosophila species maintain electrogenic muscle membrane potential to resist cold-induced depolarization

This study examines how Na+/K+-ATPase activity maintains muscle membrane potential in Drosophila species under different temperatures, finding that cold-tolerant species retain this electrogenic effect while sensitive species lose it.

Thermal acclimation of spreading depolarization in the CNS of Drosophila melanogaster

This study investigates how thermal acclimation affects spreading depolarization in Drosophila melanogaster, showing enhanced resistance to cold- and anoxic SD and interactive effects on TPP and SD propagation.

Dietary potassium and cold acclimation additively increase cold tolerance in Drosophila melanogaster

This study shows that cold acclimation and a high-potassium diet together improve cold tolerance in Drosophila by enhancing intracellular K+ levels and reducing hemolymph hyperkalemia.

Glial voltage-gated K+ channels modulate the neural abiotic stress tolerance of Drosophila melanogaster

This study shows that glial voltage-gated K+ channels, particularly those encoded by sei, are critical for modulating cold-induced spreading depolarization and stress tolerance in Drosophila melanogaster CNS.

The freeze-avoiding mountain pine beetle (Dendroctonus ponderosae) survives prolonged exposure to stressful cold by mitigating ionoregulatory collapse

This study examines how mountain pine beetle larvae maintain ion balance during cold exposure and finds that ionoregulatory collapse limits their cold tolerance.
