Zacepins, Aleksejs; Kviesis, Armands, 2025, "Bee colony temperature dynamics at the day of the swarming event", https://doi.org/10.71782/DATA/9GKLLX, DataverseLV, V1, UNF:6:ENYjdnMklj/6EgsGH9QB1Q== [fileUNF]
The dataset demonstrates bee colony temperature data on the day of the bee colony swarming. Specific day may vary from colony to colony. The dataset consists of time-series measurements collected from 10 bee colonies, which swarmed during that day. Temperature readings capture thermal regulation inside the hive, which is critical for brood developm... |
