This species shows a high basal desiccation tolerance, and cross-tolerance between desiccation and cold could have facilitated its successful establishment in temperate areas.
Polar arthropods are typically extremely tolerant of desiccation, with some being able to survive near-anhydrobiotic conditions (7).
We found that tolerance to most of the abiotic stressors tested (desiccation, paraquat, hydrogen peroxide, deltamethrin, and malathion) was high in newly eclosed adults before dramatically declining over the next days of adult life.
We characterized flies from these ten treatments (5 diets × 2 microbiota) in terms of development, body mass, food preference, body reserves, metabolic rate and a range of stress tolerance traits (heat, cold, starvation and desiccation tolerance).
Maintenance of body water homeostasis is a great challenge particularly for dormant small-bodied insects, which must prevent desiccation sometimes for several months (Yoder et al.

Predictions of this hypothesis include substantial overlap between freezing and desiccation tolerance in insects, so that physiological adaptations to desiccation stress promote cross-tolerance to freezing (Hayward et al., 2007).
In arthropods, they are induced by environmental stressors such as heat, heavy metals, ethanol, and desiccation [3,7,8].
Fst has also been reported to respond weakly to a range of abiotic stressors, such as dietary shifts, desiccation, chemical toxicity, insecticide exposure and hypoxia [10,13–16].
Gene transcription during exposure to, and recovery from, cold and desiccation stress in Drosophila melanogaster.
Sample preparation Samples for use in subsequent biochemical, proteomic and transcriptional analysis were taken immediately after the RCH treatment and a similar amount was sampled directly from the constant 25 °C cabinet (to avoid confounding effects of starvation and desiccation).
Increased hsp23 mRNA levels correlate with increased stress resistance (desiccation, starvation) in selected D.
63 mm), the plug containing absorbent cotton with distilled water to prevent desiccation, and kept in a water-bath set at 37 °C for 90 min.
