Chill coma
An attempt to select non genetic variation in resistance to starvation and reduced chill coma recovery time in Drosophila melanogaster
... Samples of natural populations of D. melanogaster were collected from a single population at Gotheron, France (44°56 ′ 0 ″ N, 04°53 ′ 30 ″ E) in June 2014 using fruit bait. Thirty isofemale lines were established ...

Chill coma temperatures appear similar along a latitudinal gradient, in contrast to divergent chill coma recovery times, in two widespread ant species
... The disparate patterns of latitudinal variation in the cold knock- down and recovery emphasize their independence from each other. This is in line with conclusions from studies on fruit flies, where the traits showed a ...
