Induced cold-tolerance mechanisms depend on duration of acclimation in the chill-sensitive Folsomia candida (Collembola).

Effect of pre-acclimation to sub lethal dose and combination of cold stress on tolerance of Folsomia candida to thiacloprid

Inducing Cold-Sensitivity in the Frigophilic Fly Drosophila montana by RNAi

Cold acclimation is a critical physiological adaptation for coping with seasonal cold. By increasing their cold tolerance individuals can remain active for longer at the onset of winter and can recover more quickly from a cold shock. In insects, despite many physiological studies, little is known about the genetic basis of cold acclimation. Recently, transcriptomic analyses in Drosophila virili...

Thermal response of lipid composition is stronger for surface dwelling than for soil dwelling springtail species

Species living under large thermal fluctuations possibly need more flexible physiological capabilities than species living in more stable thermal environments. Deep-soil dwelling species habituate more stable thermal environments than surface dwelling species. We compared the flexibility of lipid composition in response to two acclimation temperatures of soil (4), near surface (2), and surface ...

Sodium distribution predicts the chill tolerance of Drosophila melanogaster raised in different thermal conditions.

Many insects, including the model holometabolous insect Drosophila melanogaster, display remarkable plasticity in chill tolerance in response to the thermal environment experienced during development or as adults. At low temperatures, many insects lose the ability to regulate Na(+) balance, which is suggested to cause a secondary loss of hemolymph water to the tissues and gut lumen that concent...

Seasonal variation in basal and plastic cold tolerance: Adaptation is influenced by both long‐ and short‐term phenotypic plasticity

Understanding how thermal selection affects phenotypic distributions across different time scales will allow us to predict the effect of climate change on the fitness of ectotherms. We tested how seasonal temperature variation affects basal levels of cold tolerance and two types of phenotypic plasticity in Drosophila melanogaster. Developmental acclimation occurs as developmental stages of an o...
