Cold Comfort: metabolic rate and tolerance to low temperatures predict latitudinal distribution in ants

This study examines how metabolic rate and cold tolerance relate to the latitudinal distribution of ants, finding that metabolic compensation supports biogeographical models in social insects.

Balanced mitochondrial function at low temperature is linked to cold adaptation in Drosophila species

The paper investigates how mitochondrial function changes with temperature in Drosophila species, finding that cold-sensitive species show greater reduction in complex I respiration and increased use of alternative substrates at low temperatures.

Mortality without springing a leak: Locust gut epithelia do not become more permeable to fluorescent dextran and bacteria in the cold

This study investigates whether cold stress increases gut permeability in locusts by testing bacterial and fluorescent dextran leakage, finding no significant increase.

Dramatic changes in mitochondrial substrate use at critically high temperatures: a comparative study using Drosophila

This study examines how mitochondrial substrate use changes with temperature in Drosophila species, finding that heat-tolerant species maintain mitochondrial function through alternative substrates at higher temperatures.

Neural dysfunction correlates with heat coma and CTmax in Drosophila but does not set the boundaries for heat stress survival

The paper examines how neural dysfunction relates to heat coma and CTmax in Drosophila, finding that CNS failure causes heat coma but not necessarily heat mortality.

Inter- and intraspecific differences in Drosophila cold tolerance are linked to hindgut reabsorption capacity

This study investigates how cold tolerance in Drosophila is linked to hindgut reabsorption capacity, finding that cold-adapted species maintain better ion and fluid reabsorption at low temperatures.
