From: Temperature and CO2 concentration in honey bee hives exhibit circadian rhythms
Lomb-Scargle periodogram averages for 6 d raw data from the Summer 2023 experiments for colonies kept under total darkness (“CSU avg”) and colonies kept outside during the same period (“Outside avg”). (A) Hive temperature; and (B) Hive CO2 concentration. Lighter colors show standard errors for each line.
