Effect of CO2 on chronic cold tolerance and fertility in Drosophila melanogaster
Huron Park S.S.

This experiment looked at the effects of CO2 anaesthetic on chronic cold tolerance in Drosophila melanogaster. Both hypotheses were rejected as there was no mortality or reduced fertility in flies exposed to CO2. CO2 did cause chill coma recovery time to be slower and cold caused reduced fertility in flies. Future experiments involving D. melanogaster will need to use another anaesthetic, or risk compromised results.
